PCIe Fundamentals Server Storage I/O Network Essentials

PCIe fundamentals data infrastructure trends

This piece looks at PCIe Fundamentals topics for server, storage, I/O network data infrastructure environments. Peripheral Computer Interconnect (PCI) Express aka PCIe is a Server, Storage, I/O networking fundamentals component. This post is an excerpt from chapter 4 (Chapter 4: Servers: Physical, Virtual, Cloud, and Containers) of my new book Software Defined Data Infrastructure Essentials – Cloud, Converged and Virtual Fundamental Server Storage I/O Tradecraft (CRC Press 2017) Available via Amazon.com and other global venues. In this post, we look various PCIe fundamentals to learn and expand or refresh your server, storage, and I/O and networking tradecraft skills experience.

PCIe fundamentals Server Storage I/O Fundamentals

PCIe fundamental common server I/O component

Common to all servers is some form of a main system board, which can range from a few square meters in supercomputers, data center rack, tower, and micro towers converged or standalone, to small Intel NUC (Next Unit of Compute), MSI and Kepler-47 footprint, or Raspberry Pi-type desktop servers and laptops. Likewise, PCIe is commonly found in storage and networking systems, appliances among other devices.

For example, a blade server will have multiple server blades or modules, each with its motherboard, which shares a common back plane for connectivity. Another variation is a large server such as an IBM “Z” mainframe, Cray, or another supercomputer that consists of many specialized boards that function similar to a smaller-sized motherboard on a larger scale.

Some motherboards also have mezzanine or daughter boards for attachment of additional I/O networking or specialized devices. The following figure shows a generic example of a two-socket, with eight-memory-channel-type server architecture.

The above figure shows several PCIe, USB, SAS, SATA, 10 GbE LAN, and other I/O ports. Different servers will have various combinations of processor, and Dual Inline Memory Module (DIMM) Dynamic RAM (DRAM) sockets along with other features. What will also vary are the type and some I/O and storage expansion ports, power and cooling, along with management tools or included software.

PCIe, Including Mini-PCIe, NVMe, U.2, M.2, and GPU

At the heart of many servers I/O and connectivity solutions are the PCIe industry-standard interface (see PCIsig.com). PCIe is used to communicate with CPUs and the outside world of I/O networking devices. The importance of a faster and more efficient PCIe bus is to support more data moving in and out of servers while accessing fast external networks and storage.

For example, a server with a 40-GbE NIC or adapter would have to have a PCIe port capable of 5 GB per second. If multiple 40-GbE ports are attached to a server, you can see where the need for faster PCIe interfaces come into play.

As more VM are consolidated onto PM, as applications place more performance demand either regarding bandwidth or activity (IOPS, frames, or packets) per second, more 10-GbE adapters will be needed until the price of 40-GbE (also 25, 50 or 100 Gbe) becomes affordable. It is not if, but rather when you will grow into the performance needs on either a bandwidth/throughput basis or to support more activity and lower latency per interface.

PCIe is a serial interface specified for how servers communicate between CPUs, memory, and motherboard-mounted as well as AiC devices. This communication includes support attachment of onboard and host bus adapter (HBA) server storage I/O networking devices such as Ethernet, Fibre Channel, InfiniBand, RapidIO, NVMe (cards, drives, and fabrics), SAS, and SATA, among other interfaces.

In addition to supporting attachment of traditional LAN, SAN, MAN, and WAN devices, PCIe is also used for attaching GPU and video cards to servers. Traditionally, PCIe has been focused on being used inside of a given server chassis. Today, however, PCIe is being deployed on servers spanning nodes in dual, quad, or CiB, CI, and HCI or Software Defined Storage (SDS) deployments. Another variation of PCIe today is that multiple servers in the same rack or proximity can attach to shared devices such as storage via PCIe switches.

PCIe components (hardware and software) include:

  • Hardware chipsets, cabling, connectors, endpoints, and adapters
  • Root complex and switches, risers, extenders, retimers, and repeaters
  • Software drivers, BIOS, and management tools
  • HBAs, RAID, SSD, drives, GPU, and other AiC devices
  • Mezzanine, mini-PCIe, M.2, NVMe U.2 (8639 drive form factor)

There are many different implementations of PCIe, corresponding to generations representing speed improvements as well as physical packing options. PCIe can be deployed in various topologies, including a traditional model where an AiC such as GbE or Fibre Channel HBA connects the server to a network or storage device.

Another variation is for a server to connect to a PCIe switch, or in a shared PCIe configuration between two or more servers. In addition to different generations and topologies, there are also various PCIe form factors and physical connectors (see the following figure), ranging from AiC of various length and height, as well as M.2 small-form-factor devices and U.2 (8639) drive form-factor device for NVMe, among others.

Note that the presence of M.2 does not guarantee PCIe NVMe, as it also supports SATA.

Likewise, different NVMe devices run at various PCIe speeds based on the number of lanes. For example, in the following figure, the U.2 (8639) device (looks like a SAS device) shown is a PCIe x4.

SDDC, SDI, SDDI PCIe NVMe U.2 8639 drive fundamentals

PCIe leverages multiple serial unidirectional point-to-point links, known as lanes, compared to traditional PCI, which used a parallel bus design. PCIe interfaces can have one (x1), four (x4), eight (x8), sixteen (x16), or thirty-two (x32) lanes for data movement. Those PCIe lanes can be full-duplex, meaning data is sent and received at the same time, providing improved effective performance.

PCIe cards are upward-compatible, meaning that an x4 can work in an x8, an x8 in an x16, and so forth. Note, however, that the cards will not perform any faster than their specified speed; an x4 in an x8 slot will only run at x8. PCIe cards can also have single, dual, or multiple external ports and interfaces. Also, note that there are still some motherboards with legacy PCI slots that are not interoperable with PCIe cards and vice versa.

Note that PCIe cards and slots can be mechanically x1, x4, x8, x16, or x32, yet electrically (or signal) wired to a slower speed, based on the type and capabilities of the processor sockets and corresponding chipsets being used. For example, you can have a PCIe x16 slot (mechanical) that is wired for x8, which means it will only run at x8 speed.

In addition to the differences between electrical and mechanical slots, also pay attention to what generation the PCIe slots are, such as Gen 2 or Gen 3 or higher. Also, some motherboards or servers will advertise multiple PCIe slots, but those are only active with a second or additional processor socket occupied by a CPU. For example, a PCIe card that has dual x4 external PCIe ports requiring full PCIe bandwidth will need at least PCIe x8 attachment in the server slot. In other words, for full performance, the external ports on a PCIe card or device need to match the external electrical and mechanical card type and vice versa.

Recall big “B” as in Bytes vs. little “b” as in bits; for example, a PCIe Gen 3 x4 electrical could provide up to 4 GB/s bandwidth (your mileage and performance will vary), which translates to 8 × 4 GB or 32 Gbits/s. In the following table below, there is a mix of Big “B” Bytes per second and small “b” bits per second.

Each generation of PCIe has improved on the previous one by increasing the effective speed of the links. Some of the speed improvements have come from faster clock rates while implementing lower overhead encoding (e.g., from 8 b/10 b to 128 b/130 b).

For example, PCIe Gen 3 raw bit or line rate is 8 GT/s or 8 Gbps or about 2 GBps by using a 128 b/130 b encoding scheme that is very efficient compared to PCIe Gen 2 or Gen 1, which used an 8 b/10 b encoding scheme. With 8 b/10 b, there is a 20% overhead vs. a 1.5% overhead with 128 b/130 b (i.e., of 130 bits sent, 128 bits contain data, and 2 bits are for overhead).

Above Table: PCIe Generation and Sample Lane Comparison

Note that PCIe Gen 3 is the currently generally available shipping technology with PCIe Gen 4 appearing in the not so distant future, with PCIe Gen 5 in the wings appearing a few more years down the road.

By contrast, older generations of Fibre Channel and Ethernet also used 8 b/10 b, having switched over to 64 b/66 b encoding with 10 Gb and higher. PCIe, like other serial interfaces and protocols, can support full-duplex mode, meaning that data can be sent and received concurrently.

PCIe Bit Rate, Encoding, Giga Transfers, and Bandwidth

Let’s clarify something about data transfer or movement both internal and external to a server. At the core of a server, there is data movement within the sockets of the processors and its cores, as well as between memory and other devices (internal and external). For example, the QPI bus is used for moving data between some Intel processors whose performance is specified in giga transfers (GT).

PCIe is used for moving data between processors, memory, and other devices, including internal and external facing devices. Devices include host bus adapters (HBAs), host channel adapters (HCAs), converged network adapters (CNAs), network interface cards (NICs) or RAID cards, and others. PCIe performance is specified in multiple ways, given that it has a server processor focus which involves GT for raw bit rate as well as effective bandwidth per lane.

Note to keep in perspective PCIe mechanical as well as electrical lanes in that a card or slot may be advertised as say x8 mechanical (e.g., its physical slot form factor) yet only be x4 electrical (how many of those lanes are used or enabled). Also in the case of an adapter that has two or more ports, if the device is advertised as x8 does that mean it is x8 per port or x4 per port with an x8 connection to the PCIe bus.

Effective bandwidth per lane can be specified as half- or full-duplex (data moving in one or both directions for send and receive). Also, effective bandwidth can be specified as a single lane (x1), four lanes (x4), eight lanes (x8), sixteen lanes (x16), or 32 lanes (x32), as shown in the above table. The difference in speed or bits moved per second between the raw bit or line rate, and the effective bandwidth per lane in a single direction (i.e., half-duplex) is the encoding that is common to all serial data transmissions.

When data gets transmitted, the serializer/deserializer, or serdes, convert the bytes into a bit stream via encoding. There are different types of encoding, ranging from 8 b/10 b to 64 b/66 b and 128 b//130 b, shown in the following table.

Above Table: Low-Level Serial Encoding Data Transmit Efficiency

In these encoding schemes, the smaller number represents the amount of data being sent, and the difference is the overhead. Note that this is different yet related to what occurs at a higher level with the various network protocols such as TCP/IP (IP). With IP, there is a data payload plus addressing and other integrity and management features in a given packet or frame.

The 8-b/10-b, 64-b/66-b or 128-b/130-b encoding is at the lower physical layer. Thus, a small change there has a big impact and benefit when optimized. Table 4.2 shows comparisons of various encoding schemes using the example of moving a single 1542-byte packet or frame, as well as sending (or receiving) 64 packets or frames that are 1542 bytes in size.

Why 1542? That is a standard IP packet including data and protocol framing without using jumbo frames (MTU or maximum transmission units).

What does this have to do with PCIe? GbE, 10-GbE, 40-GbE, and other physical interfaces that are used for moving TCP/IP packets and frames interface with servers via PCIe.

This encoding is important as part of server storage I/O tradecraft regarding understanding the impact of performance and network or resource usage. It also means understanding why there are fewer bits per second of effective bandwidth (independent of compression or deduplication) vs. line rate in either half- or full-duplex mode.

Another item to note is that looking at encoding such as the example given in the above table shows how a relatively small change at a large scale can have a big effective impact benefit. If the bits and bytes encoding efficiency and effectiveness scenario in Table 4.2 do not make sense, then try imagining 13 MINI Cooper automobiles each with eight people in it (yes, that would be a tight fit) end to end on the same road.

Now imagine a large bus that takes up much less length on the road than the 13 MINI Coopers. The bus holds 128 people, who would still be crowded but nowhere near as cramped as eight people in a MINI, plus 24 additional people can be carried on the bus. That is an example of applying basic 8-b/10-b encoding (the MINI) vs. applying 128-b/130-b encoding (the bus) and is also similar to PCIe G3 and G4, which use 128-b/130-b encoding for data movement.

PCIe Topologies

The basic PCIe topology configuration has one or more devices attached to the root complex shown in the following figure via an AiC or onboard device connector. Examples of AiC and motherboard-mounted devices that attach to PCIe root include LAN or SAN HBA, networking, RAID, GPU, NVM or SSD, among others. At system start-up, the server initializes the PCIe bus and enumerates the devices found with their addresses.

PCIe devices attach (shown in the following figure) to a bus that communicates with the root complex that connects with processor CPUs and memory. At the other end of a PCIe device is an end-point target, a PCIe switch that in turn has end-point targets attached. From a software standpoint, hypervisor or operating system device drivers communicate with the PCI devices that in turn send or receive data or perform other functions.

SDDC, SDI, SDDI PCIe fundamentals
Basic PCIe root complex with a PCIe switch or expander.

Note that in addition to PCIe AiC such as HBAs, GPU, and NVM SSD, among others that install into PCIe slots, servers also have converged storage or disk drive enclosures that support a mix of SAS, SATA, and PCIe. These enclosure backplanes have a connector that attaches to a SAS or SATA onboard port, or a RAID card, as well as to a PCIe riser card or motherboard connector. Depending on what type of drive is installed in the connector, either the SAS, SATA, or NVMe (AiC, U.2, and M2) using PCIe communication paths are used.

In addition to traditional and switched PCIe, using PCIe switches as well as nontransparent bridging (NTB), various other configurations can be deployed. These include server to server for clustering, failover, or device sharing as well as fabrics. Note that this also means that while traditionally found inside a server, PCIe can today use an extender, retimer, and repeaters extended across servers within a rack or cabinet.

A nontransparent bridge (NTB) is a point-to-point connection between two PCIe-based systems that provide electrical isolation yet functions as a transport bridge between two different address domains. Hosts on either side of the NTB see their respective memory or I/O address space. The NTB presents an endpoint exposed to the local system where writes are mirrored to memory on the remote system to allow the systems to communicate and share devices using associated device drivers. For example, in the following figure, two servers, each with a unique PCIe root complex, address, and memory map, are shown using NTB to any communication between the systems while maintaining data integrity.

SDDC, SDI, SDDI PCIe two server fundamentals
PCIe dual server example using NTB along with switches.

General PCIe considerations (slots and devices) include:

  • Power consumption (and heat dissipation)
  • Physical and software plug-and-play (good interoperability)
  • Drivers (in-the-box, built into the OS, or add-in)
  • BIOS, UEFI, and firmware being current versions
  • Power draw per card or adapters
  • Type of processor, socket, and support chip (if not an onboard processor)
  • Electrical signal (lanes) and mechanical form factor per slot
  • Nontransparent bridge and root port (RP)
  • PCI multi-root (MR), single-root (SR), and hot plug
  • PCIe expansion chassis (internal or external)
  • External PCIe shared storage

Various operating system and hypervisor commands are available for viewing and managing PCIe devices. For example, on Linux, the “lspci” and “lshw–c pci” commands displays PCIe devices and associated information. On a VMware ESXi host, the “esxcli hardware pci list” command will show various PCIe devices and information, while on Microsoft Windows systems, “device manager” (GUI) or “devcon” (command line) will show similar information.

Who Are Some PCIe Fundamentals Vendors and Service Providers

While not an exhaustive list, here is a sampling of some vendors and service providers involved in various ways with PCIe from solutions to components to services to trade groups include Amphenol (connectors and cables), AWS (cloud data infrastructure services), Broadcom (PCIe components), Cisco (servers), DataOn (servers), Dell EMC (servers, storage, software), E8 (storage software), Excelero (storage software), HPE (storage, servers), Huawei (storage, servers), IBM, Intel (storage, servers, adapters), Keysight (test equipment and tools).

Introducing Windows Subsystem for Linux WSL Overview #blogtober

Introducing Windows Subsystem for Linux WSL Overview #blogtober

server storage I/O data infrastructure trends

Updated 1/21/2018

Introducing Windows Subsystem for Linux WSL and Overview. Microsoft has been increasing their support of Linux across Azure public cloud, Hyper-V and Linux Integration Services (LIS) and Windows platforms including Windows Subsystem for Linux (WSL) as well as Server along with Docker support.

WSL installed with Ubuntu on Windows 10

WSL with Ubuntu installed and open in a window on one of my Windows 10 systems.

WSL is not a virtual machine (VM) running on Windows or Hyper-V, rather it is a subsystem that coexists next to win32 (read more about how it works and features, enhancements here). Once installed, WSL enables use of Linux bash shell along with familiar tools (find, grep, sed, awk, rsync among others) as well as services such as ssh, MySQL among others.

What this all means is that if you work with both Windows and Linux, you can do so on the same desktop, laptop, server or system using your preferred commands. For example in one window you can be using Powershell or traditional Windows commands and tools, while in another window working with grep, find and other tools eliminating the need to install things such as wingrep among others.

Installing WSL

Depending on which release of Windows desktop or server you are running, there are a couple of different install paths. Since my Windows 10 is the most recent release (e.g. 1709) I was able to simply go to the Microsoft Windows Store via desktop, search for Windows Linux, select the distribution, install and launch. Microsoft has some useful information for installing WSL on different Windows version here, as well as for Windows Servers here.

Get WSL from Windows Store

Get WSL from Windows Store or more information and options here.

Microsoft WSL install

Click on Get the app

Select which Linux for WSL to install

Select desired WSL distribution

SUSE linux for WSL

Lests select SUSE as I already have Ubuntu installed (I have both)

WSL installing SUSE

SUSE WSL in the process of downloading. Note SUSE needs an access code (free) that you get from https://www.suse.com/subscriptions/sles/developer/ while waiting for the download and install is a good time to get that code.

launching WSL on Windows 10

Launching WSL with SUSE, you will be prompted to enter the code mentioned above, if you do not have a code, get it here from SUSE.

completing install of WSL

The WSL installation is very straight forward, enter the SUSE code (Ubuntu did not need a code). Note the Ubuntu and SUSE WSL task bar icons circled bottom center.

Ubuntu and SUSE WSL on Windows 10

Provide a username for accessing the WSL bash shell along with password, confirm how root and sudo to be applied and that is it. Serious, the install for WSL at least with Windows 10 1709 is that fast and easy. Note in the above image, I have WSL with Ubuntu open in a window on the left, WSL with SUSE on the right, and their taskbar icons bottom center.

Windows WSL install error 0x8007007e

Enable Windows Subsystem for Linux Feature on Windows

If you get the above WSL error message 0x8007007e when installing WSL Ubuntu, SUSE or other shell distro, make sure to enable the Windows WSL feature if not already installed.

Windows WSL install error fix

One option is to install additional Windows features via settings or control panel. For example, Control panel -> Programs and features -> Turn Windows features on or off -> Check the box for Windows Subsystem for Linux

Another option is to install Windows subsystem feature via Powershell for example.

enable-windowsoptionalfeature -online  -featurename microsoft-windows-subsystem-linux

Using WSL

Once you have WSL installed, try something simple such as view your present directory:

pwd

Then look at the Windows C: drive location

ls /mnt/c -al

In case you did not notice the above, you can use Windows files and folders from the bash shell by placing /mnt in front of the device path. Note that you need to be case-sensitive such as User vs. user or Documents vs. documents.

As a further example, I needed to change several .htm, .html, .php and .xml files on a Windows system whose contents had not yet changed from https://storageio.com to https://storageio.com. Instead of installing wingrep or some tools, using WSL such as with Ubuntu finding files can be done with grep such as:

grep "https://storageio.com" /mnt/c/Users/*.xml

And then making changes using find and sed such as:

find /mnt/c/Users -name \*.xml -exec sed  -i "s,https://storageio.com,https://storageio.com,g" {} \;

Note that not all Linux apps and tools can use file via /mnt in which case a solution is to create a symbolic link.

For example:

ln -s "/mnt/c/Users/Test1/Documents"  /home/Test1/Projects

What This All Means

If you primarily work on (or have a preference for) Linux systems and need to do some functions from development to the administration or other activity on a Windows system, Windows Subsystem for Linux (WSL) provides a bash shell to do familiar tasks. Likewise, if you are primarily a Windows person and need to brush up on your Linux skills, WSL can help. If you need to run Linux server applications or workloads, put those into a Docker container, Hyper-V instance or Azure VM.

Overall I like WSL for what it is, a tool that eliminates the need of having to install several other tools to do common tasks, plus makes it easier to work across various Linux and Windows systems including bare metal, virtual and cloud-based. Now that you have been introduced to Windows Subsystems for Linux WSL and an overview including install as well as using, add it to your data infrastructure toolbox.

By the way, if you have not heard, its #Blogtober, check out some of the other blogs and posts occurring during October here.

Fixing the Microsoft Windows 10 1709 post upgrade restart loop

Fixing the Microsoft Windows 10 1709 post upgrade restart loop

server storage I/O data infrastructure trends

Updated 1/21/2018

Recently I needed to upgrade one of my systems to Microsoft Windows 10 1709 (e.g. the September 2017) release that post upgrade resulted in Windows Explorer, desktop and taskbar going into an endless loop. For those not familiar with Windows 10 1709 learn more here, and here including on how to get the bits (e.g. software). Windows 10 1709 is a semi-annual channel (SAC) Microsoft is following to enable a faster cadence or pace of releases making new features available faster. Note that there is a Windows 10 1709 SAC, as well as Windows Server 2017 SAC (more on that here).

All was well with the 1709 install on Windows 10 until post upgrade when I logged into my account on my laptop (Lenovo X1). Once logged in initially everything looked good until about 10 to 20 seconds later, the screen flickered, the desktop refreshed as did the taskbar. All was well for about another 10 to 20 seconds and again the desktop refreshed as did the taskbar. Trying to use the Windows key plus other keys was no success, likewise trying to use command prompt, Powershell or other tools was futile given how quick the refresh occurred.

Powering off the system and rebooting seemed normal, until once logged in and again the desktop and taskbar reset in the same looping fashion. Once again did a shutdown and restart, logged in and the same result.

The Safe Mode Fix

Unless you can access a command prompt or Powershell with administrator privileges, boot into Windows Safe mode.

The solution to the post Windows 10 1709 upgrade desktop and taskbar restart loop was to boot into safe mode and run the following three commands.

sfc /scannow


dism.exe /online /cleanup-image /scanhealth


dism.exe /online /cleanup-image /restorehealth

Before you can run the above commands, access Windows Safe Mode. Tip if your Windows 10 system presents a login screen, in the lower right corner select the Shutdown, Restart icon holding down the SHIFT key and select Restart. Your system should reboot presenting you with the following options, selecting Troubleshoot.

Windows 10 Troubleshoot

Next select Advanced options shown below.

Windows 10 Advanced Repair Options

Next select Startup Settings shown below. Note that this sequence of commands are also used for other troubleshooting scenarios including boot problems, restore image or to a previous protection point among other options.

Windows 10 System Repair Options

The following Startup Settings screen appears, select Restart to enter Safe Mode.

Windows 10 Startup Settings

Your system should then present the following options, select Safe Mode with Command Prompt (option 6).

Windows Safe Mode Options

Next your system should display a Command Prompt where the following three commands are run:

sfc /scannow
dism.exe /online /cleanup-image /scanhealth
dism.exe /online /cleanup-image /restorehealth

Windows Command Prompt in safe mode

Exit, shutdown, reboot and all should be good.

Some Tips and Recommendations

Before any upgrade, make sure you have good backups to enable various recovery points if needed.

If you have not done so recently, make sure you have system restore enabled, as well as underlying hypervisors or storage system snapshot.

If you have bitlocker enabled, before you do any upgrade, make sure to have a copy of your keys handy if you need to use them.

If you rely on PIN or fingerprint for login, make sure you have your real password handy.

If you have not done so recently, make sure your secondary standby emergency access account is working, if you dont have one, create one.

What This All Means

For those who are planning on upgrading to Windows 10 1709 or any system for that matter, being ready for the unexpected can help when the unexpected does occur. While the above is focused on Windows 10 1709 upgrade, the tips and tools including safe mode are used for many other situations. Keep in mind that if something can go wrong sometime, sometime it will go wrong, so be prepared. As for Microsoft Windows 10 1709 post upgrade, all is good and it is running well on my different systems including physical as well as virtual devices.

Cloud Conversations AWS Azure Service Maps via Microsoft

Cloud Conversations AWS Azure Service Maps via Microsoft

server storage I/O data infrastructure trends

Updated 1/21/2018

Microsoft has created an Amazon Web Service AWS Azure Service Map. The AWS Azure Service Map is a list created by Microsoft looks at corresponding services of both cloud providers.

Azure AWS service map via Microsoft.com
Image via Azure.Microsoft.com

Note that this is an evolving work in progress from Microsoft and use it as a tool to help position the different services from Azure and AWS.

Also note that not all features or services may not be available in different regions, visit Azure and AWS sites to see current availability.

As with any comparison they are often dated the day they are posted hence this is a work in progress. If you are looking for another Microsoft created why Azure vs. AWS then check out this here. If you are looking for an AWS vs. Azure, do a simple Google (or Bing) search and watch all the various items appear, some sponsored, some not so sponsored among others.

Whats In the Service Map

The following AWS and Azure services are mapped:

  • Marketplace (e.g. where you select service offerings)
  • Compute (Virtual Machines instances, Containers, Virtual Private Servers, Serverless Microservices and Management)
  • Storage (Primary, Secondary, Archive, Premium SSD and HDD, Block, File, Object/Blobs, Tables, Queues, Import/Export, Bulk transfer, Backup, Data Protection, Disaster Recovery, Gateways)
  • Network & Content Delivery (Virtual networking, virtual private networks and virtual private cloud, domain name services (DNS), content delivery network (CDN), load balancing, direct connect, edge, alerts)
  • Database (Relational, SQL and NoSQL document and key value, caching, database migration)
  • Analytics and Big Data (data warehouse, data lake, data processing, real-time and batch, data orchestration, data platforms, analytics)
  • Intelligence and IoT (IoT hub and gateways, speech recognition, visualization, search, machine learning, AI)
  • Management and Monitoring (management, monitoring, advisor, DevOps)
  • Mobile Services (management, monitoring, administration)
  • Security, Identity and Access (Security, directory services, compliance, authorization, authentication, encryption, firewall
  • Developer Tools (workflow, messaging, email, API management, media trans coding, development tools, testing, DevOps)
  • Enterprise Integration (application integration, content management)

What This All Means

On one hand this can and will likely be used as a comparison however use caution as both Azure and AWS services are rapidly evolving, adding new features, extending others. Likewise the service regions and site of data centers also continue to evolve thus use the above as a general guide or tool to help map what service offerings are similar between AWS and Azure.

Amazon Web Service AWS September 2017 Software Defined Data Infrastructure Updates

Amazon Web Service AWS September 2017 Software Defined Data Infrastructure Updates

server storage I/O data infrastructure trends

Amazon Web Service AWS September 2017 Software Defined Data Infrasture Updates

September was a busy month pertaining to software defined data infrastructure including cloud and related AWS announcements. One of the announcements included VMware partnering to deliver vSphere, vSAN and NSX data infrastructure components for creating software defined data centers (SDDC) also known as multi cloud, and hybrid cloud leveraging AWS elastic bare metal servers (read more here in a companion post). Unlike traditional partner software defined solutions that relied on AWS Elastic Cloud Compute (EC2) instances, VMware is being deployed using private bare metal AWS elastic servers.

What this means is that VMware vSphere (e.g. ESXi) hypervisor, vCenter, software defined storage (vSAN), storage defined network (NSX) and associated vRealize tools are deployed on AWS data infrastructure that can be used for deploying hybrid software defined data centers (e.g. connecting to your existing VMware environment). Learn more about VMware on AWS here or click on the following image.

VMware on AWS via Amazon.com

Additional AWS Updates

Amazon Web Services (AWS) updates include, coinciding with VMworld, the initial availability of VMware on AWS (using virtual private servers e.g. think along the lines of Lightsail, not EC2 instances) was announced. Amazon Web Services (AWS) continues its expansion into database and table services with Relational Data Services (RDS) including various engines (Amazon Auora,MariaDB, MySQL, Oracle, PostgreSQL,and SQL Server along with Database Migration Service (DMS). Note that these RDS are in addition to what you can install and run your self on Elastic Cloud Compute (EC2) virtual machine instances, Lambda serverless containers, or Lightsail Virtual Private Servers (VPS).

AWS has published a guide to database testing on Amazon RDS for Oracle plotting latency and IOPs for OLTP workloads here using SLOB. If you are not familiar with SLOB (Silly Little Oracle Benchmark) here is a podcast with its creator Kevin Closson discussing database performance and related topics. Learn more about SLOB and step by step installation for AWS RDS Oracle here, and for those who are concerned or think that you can not run workloads to evaluate Oracle platforms, have a look at this here.

EC2 enhancements include charging by the second (previous by the hour) for some EC2 instances (see details here including what is or is not currently available) which is a growing trend by private cloud vendors aligning with how serverless containers have been billed. New large memory EC2 instances that for example support up to 3,904GB of DDR4 RAM have been added by AWS. Other EC2 enhancements include updated network performance for some instances, OpenCL development environment to leverage AWS F1 FPGA enabled instances, along with new Elastic GPU enabled instances. Other server and network enhancements include Network Load Balancer for Elastic Load Balancer announced, as well as application load balancer now supports load balancing to IP address as targets for AWS and on premises (e.g. hybrid) resources.

Other updates and announces include data protection backups to AWS via Commvault and AWS Storage Gateway VTL announced. IBM has announced their Spectrum Scale (e.g. formerly known as SONAS aka GPFS) Scale Out Storage solution for high performance compute (HPC) quick start on AWS. Additional AWS enhancements include new edge location in Boston and a third Seattle site, while Direct Connect sites have been added in Boston and Houston along with Canberra Australia. View more AWS announcements and enhancements here.

Where To Learn More

What This All Means

AWS continues to grow and expand, both in terms of number of services, also the extensiveness of them. Likewise AWS continues to add more regions and data center availability zones, enhanced connectivity, along with earlier mentioned service features. The partnership with VMware should enable enterprise organizations to move towards hybrid cloud data infrastructures, while giving AWS an additional reach into those data centers. Overall a good set of enhancements by AWS who continues to evolve their cloud and software defined data infrastructure portfolio of solution offerings.

Dell EMC VMware September 2017 Software Defined Data Infrastructure Updates

Dell EMC VMware September 2017 Software Defined Data Infrastructure Updates

server storage I/O data infrastructure trends

Dell EMC VMware September 2017 Software Defined Data Infrastructure Updates

vmworld 2017

September was a busy month including VMworld in Las Vegas that featured many Dell EMC VMware (among other) software defined data infrastructure updates and announcements.

A summary of September VMware (and partner) related announcements include:

VMware on AWS via Amazon.com
VMware and AWS via Amazon Web Services

VMware and AWS

Some of you might recall VMware earlier attempt at public cloud with vCloud Air service (see Server StorageIO lab test drive here) which has since been depreciated (e.g. retired). This new approach by VMware leverages the large global presence of AWS enabling customers to set up public or hybrid vSphere, vSAN and NSX based clouds, as well as software defined data centers (SDDC) and software defined data infrastructures (SDDI).

VMware Cloud on AWS exists on a dedicated, single-tenant (unlike Elastic Cloud Compute (EC2) multi-tenant instances or VMs) that supports from 4 to 16 underlying host per cluster. Unlike EC2 virtual machine instances, VMware Cloud on AWS is delivered on elastic bare-metal (e.g. dedicated private servers aka DPS). Note AWS EC2 is more commonly known, AWS also has other options for server compute including Lambda micro services serverless containers, as well as Lightsail virtual private servers (VPS).

Besides servers with storage optimized I/O featuring low latency NVMe accessed SSDs, and applicable underlying server I/O networking, VMware Cloud on AWS leverages the VMware software stack directly on underlying host servers (e.g. there is no virtualization nesting taking place). This means more robust performance should be expected like in your on premise VMware environment. VM workloads can move between your onsite VMware systems and VMware Cloud on AWS using various tools. The VMware Cloud on AWS is delivered and managed by VMware, including pricing. Learn more about VMware Cloud on AWS here, and here (VMware PDF) and here (VMware Hands On Lab aka HOL).

Read more about AWS September news and related updates here in this StorageIOblog post.

VMware PKS
VMware and Pivotal PKS via VMware.com

Pivotal Container Service (PKS) and Google Kubernetes Partnership

During VMworld VMware, Pivotal and Google announced a partnership for enabling Kubernetes container management called PKS (Pivotal Container Service). Kubernetes is evolving as a popular open source container microservice serverless management orchestration platform that has roots within Google. What this means is that what is good for Google and others for managing containers, is now good for VMware and Pivotal. In related news, VMware has become a platinum sponsor of the Cloud Native Compute Foundation (CNCF). If you are not familiar with CNCF, add it to your vocabulary and learn more here at www.cncf.io.

Other VMworld and September VMware related announcements

Hyper converged data infrastructure provider Maxta has announced a VMware vSphere Escape Pod (parachute not included ;) ) to facilitate migration from ESXi based to Red Hat Linux hypervisor environments. IBM and VMware for cloud partnership, along with Dell EMC, IBM and VMware joint cloud solutions. White listing of VMware vSphere VMs for enhanced security combine with earlier announced capabilities.

Note that both VMware with vSphere ESXi and Microsoft with Hyper-V (Windows and Azure based) are supporting various approaches for securing Virtual Machines (VMs) and the hosts they run on. These enhancements are moving beyond simply encrypting the VMDK or VHDX virtual disks the VMs reside in or use, as well as more than password, ssh and other security measures. For example Microsoft is adding support for host guarded fabrics (and machine hosts) as well as shielded VMs. Keep an eye on how both VMware and Microsoft extend the data protection and security capabilities for software defined data infrastructures for their solutions and services.

Dell EMC Announcements

At VMworld in September Dell EMC announcements included:

  • Hyper Converged Infrastructure (HCI) and Hybrid Cloud enhancements
  • Data Protection, Goverence and Management suite updates
  • XtremIO X2 all flash array (AFA) availability optimized for vSphere and VDI

HCI and Hybrid Cloud enhancements include VxRail Appliance, VxRack SDDC (vSphere 6.5, vSAN 6.6, NSX 6.3) along with hybrid cloud platforms (Enterprise Hybrid Cloud and Native Hybrid Cloud) along with vSAN Ready Nodes (vSAN 6.6 and encryption) and VMware Ready System. Note that Dell EMC in addition to supporting VMware hybrid clouds also previously announced solutions for Microsoft Azure Stack back in May.

Software Defined Data Infrastructure Essentials (CRC Press) at VMworld bookstore

My new book Software Defined Data Infrastructure Essentials (CRC Press) made its public debut in the VMware book store where I did a book signing event. You can get your copy of Software Defined Data Infrastructure Essentials which includes Software Defined Data Centers (SDDC) along with hybrid, multi-cloud, serverless, converged and related topics at Amazon among other venues. Learn more here.

Where To Learn More

What This All Means

A year ago at VMworld the initial conversations were started around what would become the VMware Cloud on AWS solution. Also a year ago besides VMware Integrated Containers (VIC) and some other pieces, the overall container and in particular related management story was a bit cloudy (pun intended). However, now the fog and cloud seem to be clearing with the PKS solution, along with details of VMware Cloud on AWS. Likewise vSphere, vSAN and NSX along with associated vRealize tools continue to evolve as well as customer deployment growing. All in all, VMware continues to evolve, let’s see how things progress now over the year until the next VMworld.

Microsoft Azure September 2017 Software Defined Data Infrastructure Updates

Microsoft Azure September 2017 Software Defined Data Infrastructure Updates

server storage I/O data infrastructure trends

Microsoft and Azure September 2017 Software Defined Data infrastructure Updates

September was a busy month for data infrastructure topics as well as Microsoft in terms of new and enhanced technologies. Wrapping up September was Microsoft Ignite where Azure, Azure Stack, Windows, O365, AI, IoT, development tools announcements occurred, along with others from earlier in the month. As part of the September announcements, Microsoft released a new version of Windows server (e.g. 1709) that has a focus for enhanced container support. Note that if you have deployed Storage Spaces Direct (S2D) and are looking to upgrade to 1709, do your homework as there are some caveats that will cause you to wait for the next release. Note that there had been new storage related enhancements slated for the September update, however those were announced at Ignite to being pushed to the next semi-annual release. Learn more here and also here.

Azure Files and NFS

Microsoft made several Azure file storage related announcements and public previews during September including Native NFS based file sharing as companion to existing Azure Files, along with public preview of new Azure File Sync Service. Native NFS based file sharing (public preview announced, service is slated to be available in 2018) is a software defined storage deployment of NetApp OnTAP running on top of Azure data infrastructure including virtual machines and leverage Azure underlying storage.

Note that the new native NFS is in addition to the earlier native Azure Files accessed via HTTP REST and SMB3 enabling sharing of files inside Azure public cloud, as well as accessible externally from Windows based and Linux platforms including on premises. Learn more about Azure Storage and Azure Files here.

Azure File Sync (AFS)

Azure File Sync AFS

Azure File Sync (AFS) has now entered public preview. While users of Windows-based systems have been able to access and share Azure Files in the past, AFS is something different. I have used AFS for some time now during several private preview iterations having seen how it has evolved, along with how Microsoft listens incorporating feedback into the solution.

Lets take a look at what is AFS, what it does, how it works, where and when to use it among other considerations. With AFS, different and independent systems can now synchronize file shares through Azure. Currently in the AFS preview Windows Server 2012 and 2016 are supported including bare metal, virtual, and cloud based. For example I have had bare metal, virtual (VMware), cloud (Azure and AWS) as part of participating in a file sync activities using AFS.

Not to be confused with some other storage related AFS including Andrew File System among others, the new Microsoft Azure File Sync service enables files to be synchronized across different servers via Azure. This is different then the previous available Azure File Share service that enables files stored in Azure cloud storage to be accessed via Windows and Linux systems within Azure, as well as natively by Windows platforms outside of Azure. Likewise this is different from the recently announced Microsoft Azure native NFS file sharing serving service in partnership with NetApp (e.g. powered by OnTAP cloud).

AFS can be used to synchronize across different on premise as well as cloud servers that can also function as cache. What this means is that for Windows work folders served via different on premise servers, those files can be synchronized across Azure to other locations. Besides providing a cache, cloud tiering and enterprise file sync share (EFSS) capabilities, AFS also has robust optimization for data movement to and from the cloud and across sites, along with management tools. Management tools including diagnostics, performance and activity monitoring among others.

Check out the AFS preview including planning for an Azure File Sync (preview) deployment (Docs Microsoft), and for those who have Yammer accounts, here is the AFS preview group link.

Microsoft Azure Blob Events via Microsoft

Azure Blob Storage Tiering and Event Triggers

Two other Azure storage features that are in public preview include blob tiering (for cold archiving) and event triggers for events. As their names imply, blob tiering enables automatic migration from active to cold inactive storage of dormant date. Event triggers are policies rules (code) that get executed when a blob is stored to do various functions or tasks. Here is an overview of blob events and a quick start from Microsoft here.

Keep in mind that not all blob and object storage are the same, a good example is Microsoft Azure that has page, block and append blobs. Append blobs are similar to what you might be familiar with other services objects. Here is a Microsoft overview of various Azure blobs including what to use when.

Project Honolulu and Windows Server Enhancements

Microsoft has evolved from command prompt (e.g. early MSDOS) to GUI with Windows to command line extending into PowerShell that left some thinking there is no longer need for GUI. Even though Microsoft has extended its CLI with PowerShell spanning WIndows platforms and Azure, along with adding Linux command shell, there are those who still want or need a GUI. Project Honolulu is the effort to bring GUI based management back to Windows in a simplified way for what had been headless, and desktop less deployments (e.g. Nano, Server Core). Microsoft had Server Management Tools (SMT) accessible via the Azure Portal which has been discontinued.


Project Honolulu Image via Microsoft.com

This is where project Honolulu comes into play for managing Windows Server platforms. What this means is that for those who dont want to rely on or have a PowerShell dependency have an alternative option. Learn more about Project Honolulu here and here, including download the public preview here.

Storage Spaces Direct (S2D) Kepler Appliance

Data Infrastructure provider DataOn has announced a new turnkey Windows Server 2016 Storage Spaces Direct (S2D) powered Hyper-Converged Infrastructure (e.g. productization of project Kepler-47) solution with two node small form factor servers (partner with MSI). How small? Think suitcase or airplane roller board carry on luggage size.

What this means is that you can get into the converged, hyper-converged software defined storage game with Windows-based servers supporting Hyper-V virtual machines (Windows and Linux) including hardware for around $10,000 USD (varies by configuration and other options).

Azure and Microsoft Networking News

Speaking of Microsoft Azure public cloud, ever wonder what the network that enables the service looks like and some of the software defined networking (SDN) along with network virtualization function (NFV) objectives are, have a look at this piece from over at Data Center Knowledge.

In related Windows, Azure and other focus areas, Microsoft, Facebook and Telxius have completed the installation of a high-capacity subsea cable (network) to cross the atlantic ocean. Whats so interesting from a data infrastructure, cloud or legacy server storage I/O and data center focus perspective? The new network was built by the combined companies vs. in the past by a Telco provider consortium with the subsequent bandwidth sold or leased to others.

This new network is also 4,000 miles long including in depths of 11,000 feet, supports with current optics 160 terabits (e.g. 20 TeraBytes) per second capable of supporting 71 million HD videos streamed simultaneous. To put things into perspective, some residential Fiber Optic services can operate best case up to 1 gigabit per second (line speed) and in an asymmetrical fashion (faster download than uploads). Granted there are some 10 Gbit based services out there more common with commercial than residential. Simply put, there is a large amount of bandwidth increased across the atlantic for Microsoft and Facebook to support growing demands.

Where To Learn More

Learn more about related technology, trends, tools, techniques, and tips with the following links.

What This All Means

Microsoft announced a new release of Windows Server at Ignite as part of its new semi-annual release cycle. This latest version of Windows server is optimized for containers. In addition to Windows server enhancements, Microsoft continues to extend Azure and related technologies for public, private and hybrid cloud as well as software defined data infrastructures.

September 2017 Server StorageIO Data Infrastructure Update Newsletter



Server StorageIO September 2017 Data Infrastructure Update Newsletter

Volume 17, Issue IX (September 2017)

Hello and welcome to the September 2017 issue of the Server StorageIO update newsletter.

With September being generally known as back to school month, the two September event bookends were VMware VMworld and Microsoft Ignite with many other things in between. Needless to say, a lot has happened in and around data infrastructure topic areas since the August newsletter (here if you missed it). Here is a post covering some of the things that I participated with during September including presentations at events in Las Vegas (VMworld), New York City (Wipro SDx Summit), SNIA SDC in Santa Clara, Fujifilm Executive Summitt in Seattle, Minneapolis/St. Paul CMG along with other activities.

Software-Defined Data Infrastructure Essentials SDDI SDDC

One of the activities I participated in with while at VMworld in Las Vegas was a book signing event at the VMware bookstore of my new book Software Defined Data Infrastructure Essentials (CRC Press) available at Amazon.com and other global venues.

September has been a busy month pertaining data infrastructure including server storage I/O related trends, activities, news, perspectives and related topics, so let’s have a look at them.

In This Issue

Enjoy this edition of the Server StorageIO data infrastructure update newsletter.

Cheers GS

Data Infrastructure and IT Industry Activity Trends

Some recent Industry Activities, Trends, News and Announcements include:

The month started out with VMworld in Las Vegas (e.g. one of the event bookends for the month). Rather than a long list of announcements in this newsletter, check out this StorageIOblog post covering VMworld, VMware and Dell EMC and related news. As part of VMworld, VMware and Amazon Web Services (AWS) announced news about their partnership. AWS also had several other enhancements and new product announcements during september that can be found in this StorageIOblog post here.

AWS, Dell EMC and VMware were not the only ones making news or announcements during September. Startup NVMe based storage startup Apeiron has announced a Splunk appliance to boost log and analytics processing performance. Gigamon has extended its public cloud monitoring, insight awareness and analytics capabilities including support for Microsoft Azure.

For those looking for the latest new emerging data infrastructure vendors to watch, add Vexta to your list of NVMe based storage systems. Vexta talks a lot about NVMe particular for their backend (e.g. where data stored on NVM based devices accessed via NVMe), access of their storage system is via traditional Fibre Channel (FC) or emerging NVMe over fabric.

Long time data infrastructure server and storage vendor HDS (Hitachi Data Systems) is no more (at least in name) having re branded themselves as Vantara focusing on IoT and Cloud analytics besides their traditional data center focus. Vantara combines what was HDS, Hitachi Insight Group and Pentaho into a single unit effectively based in what was HDS as a new, repackaged, refocused business unit.

Another longtime data infrastructure solution and service provider IBM announced a new Linux only zSeries (ZED) mainframe solution. Some might think the Mainframe is dead, others that it can only run Linux as a virtual guest in a virtual machine. On the other hand some might recall that there are native Linux implementations on the ZED including Ubuntu among others.

Also note that while IBM zOS mainframe operating systems use FICON for storage access, native ZED Linux systems can use open systems based Fibre Channel (FC) e.g. SCSI command set protocols. Is the ZED based Linux for everybody or every environment? Probably not, however for those who have large-scale Linux needs, it might be worth a look to do a total cost of ownership analysis. If nothing else, do your homework, play your cards right and you might have some leverage with the x86 based server crowd when it comes to negotiating leverage.

Cloud storage gateway vendor Nasuni has landed another $38 Million USD in funding, hopefully that will enable them to start landing some new and larger customer revenues growing their business. Meanwhile storage startup Qumulo has announced extending their global file fabric name space to include spanning AWS.

Attala Systems has announced next generation software defined storage for data infrastructures for Telco environments. Percona has added an experimental release of their MySQL engine enhancing performance for high volume, write intensive workloads along with improved cost effectiveness.

Software defined storage vendor Datacore announced enhancements to support fast databases for online transaction processing (OLTP) along with analytics. Meanwhile Linux provider SUSE continues to expand its software defined storage story based around Ceph. Panasas has enhanced its scale out high performance cluster file system global name space for HPC environments with 20 PByte support. Another longtime storage vendor X-IO (formerly known as Xiotech) announced their 4th generation of their Intelligent Storage Element (ISE).

September wrapped up with Microsoft Ignite conference along with many updated, enhancements and new features for Azure, Azure Stack, Windows among others. Read more about those and other Microsoft September announcements here in this StorageIOblog post.

Getting Caught Up What Happened In September 2017

server storage I/O data infrastructure trends

Getting Caught Up, What Happened In September?

Seems like just yesterday it was the end of August with the start of VMworld in Las Vegas, now its the end of September and Microsoft Ignite in Orlando is wrapping up. Microsoft has made several announcements this week at Ignite including Azure cloud related, AI, IoT, Windows platforms, O365 among others. More about Microsoft Azure, Azure Stack, Windows Server, Hyper-V and related data infrastructure topics in future posts.

Like many of you, September is a busy time of the year, so here is a recap of some of what I have been doing for the past month (among other things).

vmworld 2017

VMworld Las Vegas

During VMworld US VMware announced enhanced workspace, security and endpoint solutions, Pivotal Container Service (PKS) with Google for Kubernetes serverless container management, DXC partnership for hybrid cloud management, security enablement via its AppDefense solutions, data infrastructure platform enhancements including integrated OpenStack, vRealize management tools, vSAN among others. VMware also made announcements including expanded multi-cloud and hybrid cloud support along with VMware on AWS as well as Dell EMC data protection for VMware and AWS environments.

Software Defined Data Infrastructure Essentials (CRC Press) at VMworld bookstore

In other VMworld activity, my new book Software Defined Data Infrastructure Essentials (CRC Press) made its public debut in the VMware book store where I did a book signing event. You can get your copy of Software Defined Data Infrastructure Essentials which includes Software Defined Data Centers (SDDC) along with hybrid, multi-cloud, serverless, converged and related topics at Amazon among other venues. Learn more here.

Software Defined Everything (x)

In early September I was invited to present at the Wipro Software Defined Everything (x) event in New York City. This event follows Wipro invited me to present at in London England this past January at the inaugural SDx Summit event. At the New York City event my presentation was Planning and Enabling Your Journey to SDx which bridged the higher level big picture industry trends to the applied feet on the ground topics. Attendees of the event included customers, prospects, partners, various analyst firms along with Wipro personal.

At the Wipro event during a panel discussion a question was asked about definition of software defined. After the usual vendor and industry responses, mine was a simple, put the emphasis on Define as opposed to software, with a focus on what is the resulting outcome. In other words how and what are you defining (e.g. x) which could be storage, server, data center, data infrastructure, network among others to make a particular result, outcome, service or capability. While the emphasis is around defined, that also can mean curate, compose, craft, program or whatever you prefer to create an outcome.

Role of Storage in a Software Defined Data Infrastructure

At the Storage Network Industry Association (SNIA) Storage Developers Conference (SDC) in Santa Clara I did a talk about the role of Storage in Software Defined Data Infrastructures. The theme was that not only is there a role, storage is fundamental and essential for any software defined data infrastructure (as well as legacy) from cloud to container, serverless to virtual servers, converged and hybrid among others. Other themes included the changing role of storage along with how hardware needs software, software needs hardware, and serverless has hardware and software somewhere in the stack. Tradecraft along with other related data infrastructure topics were also discussed.

Data Infrastructures Protect Preserve Secure and Serve Information
Various IT and Cloud Infrastructure Layers including Data Infrastructures

While promoted as an event for storage developers by storage developers, based on a lot of the content presented, SNIA could easily increase attendance to a broader audience with some slight tweaks as well as messaging. If SNIA is looking to focus the event only for vendor storage developers, surprise surprise, there were developers there, however I also talked with IT customers who were there among other non developers. SDC IMHO is not a replacement for SNW, however with some simple adjustments in messaging from who shouldn’t attend to who should or could attend, more attendees and sponsors might just happen appear.

Check out the SNIA SDC presentations here, along with my presentation from the 2017 event here (among others).

tape and cloud storage

Tape in a Software Defined and Hybrid Cloud World

I was invited by Fujifilm to present at their recent 9th annual executive summit in Seattle. The Fujifilm event was attended by various partners, customers and industry folks covering a diverse set of topics. Focus areas spanned from legacy IT to hyper-scale to public cloud and High-Performance Compute (HPC) among others. Magnetic Tape (e.g. tape) may be going away from your data center, however, chances are if you are doing or storing things in the cloud, your data may end up on tape. In other words, not only does tape continue to evolve, its place and how used (as well as accessed) is also changing. Check out the Fujifilm site here where you can scroll down and check out mine and other presentations from the event.

Focus on Data Protection (and recovery)

September also saw hurricanes, tropical storms, flooding, earthquakes, and acts of natural events, to man-made accidental as well as intentional including software-defined threats such as ransomware, malware, virus, Equifax data information breaches, leaks, loss among other security concerns. A reminder that there are the headline-making news events, as well as those that may be more common yet not widely talked about. What this means is that big or small, full or partial damage, destruction, loss or loss of access, data protection should be proactive to enable recovery instead of an afterthought.

Think of data protection as an investment instead of cost overhead, however that also means finding ways to spread costs out while gaining more benefit. Also remember that if something can occur, fail or happen, it probably will. In other words, the question should not be if, rather when, with what impact. This also means evolving from backup/restore, disaster recovery to business resiliency that enables your applications and data to stay available as well as accessible. In other words, how well are you prepared?

Additional data protection related topics and content include:

  • Free Webinar (registration required) with tips for disaster recovery (DR) and business resiliency (BR)
  • Preventing Unexpected Disasters article tip via Iron Mountain
  • Server StorageIO data infrastructure data protection diaries (various tips and content)
  • Free webinar (registration required) planning for GDPR
  • Time to recover, do you know where backup data is (article from Computerweekly)
  • Ensuring your data infrastructure remains available (article from Networkworld)
  • Tips on preparing for Hurricane and storm season (via IronMountain)

Expanding Your Data Infrastructure Tradecraft

At the September Minneapolis St. Paul (MSP) Computer Measurement Group (CMG) event, I gave a presentation discussing industry trends perspectives, buzzword bingo updates including software defined, NVM (the media) vs. NVMe (the interface) benchmarking, tools, cloud, serverless and tradecraft. Tradecraft as a refresher are those skills and fundamental experiences you acquire over time including what tools, techniques to use for different scenarios.

As part of the CMG presentation, the discussion looked at expanding your data infrastructure tradecraft into adjacent areas around your current focus. Also discussed were the importance of context as different words have two or more meanings. For example SAS can mean Scandinavian Air System, Statistics Analysis Software the original unstructured and big data tool, as well as for storage Serial Attached SCSI. However there is another meaning for SAS which spans server, storage, networking, cloud, security and other focus areas which is Shared Access Signature.

Downloads the CMG and other presentations from the Server StorageIO website here.

What This All Means

The above are some of the things I was involved with during September with themes of data infrastructure, data protection, software defined cloud, virtual, serverless containers, servers, storage, I/O networking, SSD including NVMe, performance and capacity planning, metrics that matter, management among other topics. It was great meeting many new people at the various venues this past month, likewise seeing old acquaintances and friends. Also thanks to all who have ordered copies of my new book Software Defined Data Infrastructure Essentials along with your comments. Check out the Server StorageIO data infrastructure update newsletter for other related activity, industry trends among other topics. Now lets see how fast October and the rest of 2017 goes.

Software Defined Data Infrastructure Essentials Book SDDC

What This All Means

Data Infrastructures exist to protect, preserve, secure and serve information along with the applications and data they depend on. With more data being created at a faster rate, along with the size of data becoming larger, increased application functionality to transform data into information means more demands on data infrastructures and their underlying resources.

Software-Defined Data Infrastructure Essentials: Cloud, Converged, and Virtual Fundamental Server Storage I/O Tradecraft is for people who are currently involved with or looking to expand their knowledge and tradecraft skills (experience) of data infrastructures. Software-defined data centers (SDDC), software data infrastructures (SDI), software-defined data infrastructure (SDDI) and traditional data infrastructures are made up of software, hardware, services, and best practices and tools spanning servers, I/O networking, and storage from physical to software-defined virtual, container, and clouds. The role of data infrastructures is to enable and support information technology (IT) and organizational information applications.

Additional learning experiences along with common questions (and answers), as well as tips can be found in Software Defined Data Infrastructure Essentials book.

Chelsio Storage over IP and other Networks Enable Data Infrastructures

Chelsio Storage over IP Enable Data Infrastructures

server storage I/O data infrastructure trends

Chelsio and Storage over IP (SoIP) continue to enable Data Infrastructures from legacy to software defined virtual, container, cloud as well as converged. This past week I had a chance to visit with Chelsio to discuss data infrastructures, server storage I/O networking along with other related topics. More on Chelsio later in this post, however, for now lets take a quick step back and refresh what is SoIP (Storage over IP) along with Storage over Ethernet (among other networks).

Data Infrastructures Protect Preserve Secure and Serve Information
Various IT and Cloud Infrastructure Layers including Data Infrastructures

Server Storage over IP Revisited

There are many variations of SoIP from network attached storage (NAS) file based processing including NFS, SAMBA/SMB (aka Windows File sharing) among others. In addition there is various block such as SCSI over IP (e.g. iSCSI), along with object via HTTP/HTTPS, not to mention the buzzword bingo list of RoCE, iSER, iWARP, RDMA, DDPK, FTP, FCoE, IFCP, and SMB3 direct to name a few.

Who is Chelsio

For those who are not aware or need a refresher, Chelsio is involved with enabling server storage I/O by creating ASICs (Application Specific Integrated Circuits) that do various functions offloading those from the host server processor. What this means for some is a throw back to the early 2000s of the TCP Offload Engine (TOE) era where various processing to handle regular along with iSCSI and other storage over Ethernet and IP could be accelerated.

Chelsio data infrastructure focus

Chelsio ecosystem across different data infrastructure focus areas and application workloads

As seen in the image above, certainly there is a server and storage I/O network play with Chelsio, along with traffic management, packet inspection, security (encryption, SSL and other offload), traditional, commercial, web, high performance compute (HPC) along with high profit or productivity compute (the other HPC). Chelsio also enables data infrastructures that are part of physical bare metal (BM), software defined virtual, container, cloud, serverless among others.

Chelsio server storage I/O focus

The above image shows how Chelsio enables initiators on server and storage appliances as well as targets via various storage over IP (or Ethernet) protocols.

Chelsio enabling various data center resources

Chelsio also plays in several different sectors from *NIX to Windows, Cloud to Containers, Various processor architectures and hypervisors.

Chelsio ecosystem

Besides diverse server storage I/O enabling capabilities across various data infrastructure environments, what caught my eye with Chelsio is how far they, and storage over IP have progressed over the past decade (or more). Granted there are faster underlying networks today, however the offload and specialized chip sets (e.g. ASICs) have also progressed as seen in the above and next series of images via Chelsio.

The above showing TCP and UDP acceleration, the following show Microsoft SMB 3.1.1 performance something important for doing Storage Spaces Direct (S2D) and Windows-based Converged Infrastructure (CI) along with Hyper Converged Infrastructures (HCI) deployments.

Chelsio software environments

Something else that caught my eye was iSCSI performance which in the following shows 4 initiators accessing a single target doing about 4 million IOPs (reads and writes), various size and configurations. Granted that is with a 100Gb network interface, however it also shows that potential bottlenecks are removed enabling that faster network to be more effectively used.

Chelsio server storage I/O performance

Moving on from TCP, UDP and iSCSI, NVMe and in particular NVMe over Fabric (NVMeoF) have become popular industry topics so check out the following. One of my comments to Chelsio is to add host or server CPU usage to the following chart to help show the story and value proposition of NVMe in general to do more I/O activity while consuming less server-side resources. Lets see what they put out in the future.

Chelsio

Ok, so Chelsio does storage over IP, storage over Ethernet and other interfaces accelerating performance, as well as regular TCP and UDP activity. One of the other benefits of what Chelsio and others are doing with their ASICs (or FPGA by some) is to also offload processing for security among other topics. Given the increased focus around server storage I/O and data infrastructure security from encryption to SSL and related usage that requires more resources, these new ASIC such as from Chelsio help to offload various specialized processing from the server.

The customer benefit is that more productive application work can be done by their servers (or storage appliances). For example, if you have a database server, that means more product ivy data base transactions per second per licensed software. Put another way, want to get more value out of your Oracle, Microsoft or other vendors software licenses, simple, get more work done per server that is licensed by offloading and eliminate waits or other bottlenecks.

Using offloads and removing server bottlenecks might seem like common sense however I’m still amazed that the number of organizations who are more focused on getting extra value out of their hardware vs. getting value out of their software licenses (which might be more expensive).

What This All Means

Data Infrastructures exist to protect, preserve, secure and serve information along with the applications and data they depend on. With more data being created at a faster rate, along with the size of data becoming larger, increased application functionality to transform data into information means more demands on data infrastructures and their underlying resources.

This means more server I/O to storage system and other servers, along with increased use of SoIP as well as storage over Ethernet and other interfaces including NVMe. Chelsio (and others) are addressing the various application and workload demands by enabling more robust, productive, effective and efficient data infrastructures.

Check out Chelsio and how they are enabling storage over IPO (SoIP) to enable Data Infrastructures from legacy to software defined virtual, container, cloud as well as converged, oh, and thanks Chelsio for being able to use the above images.

Ok, nuff said, for now.
