Intel Micron 3D XPoint Evolving

Generations of memory
Major memory classes or categories timeline (Image via Intel and Micron)

Co-Creators of 3D XPoint the next generation of non-volatile memory (NVM) also known as storage class memory (SCM) or Persistent Memory (PMEM) have announced they will complete joint development of second-generation technology, then pursue their separate paths. Intel and Micron jointly announced 3D XPoint three years (July 2015) as a new technology with the first generation of products have appeared in the market or past year or so.

Various industry vs customer adoption deployment timelines
Various Adoption Deployment Timelines for different focus areas

For those in the industry who measure technology on shorter months vs. years adoption and deployment scenarios, or time from press release until new news, some would say 3D XPoint is late, behind schedule, which perhaps it is based on some timelines. On the other hand, IT customers tend to be on a different timeline that may seem like glacial speed to industry focused rapid change. IMHO 3D XPoint is about on the right timeline based on IT customer deployment which may very well accelerate for broader usage with the second generation based products.

While the focus is easily around Intel and Micron going separate ways, keep in mind that there is the second generation of 3D XPoint in the works. Some might consider the second generation of 3D XPoint as the first real production and volume technology with the first being just that, the first generation. An example of a first generation 3D XPoint based product are the Intel Optane NVMe devices such as the one show above, and discussed in this StorageIO Lab test drive post here.

What this all means

Some may see the announcement of Intel and Micron pursuing separate paths as a negative while others as a positive. While completing the second-generation development together, both can leverage what they have done while seeking different, presumably divergent or expand paths forward.

A concern could be if Intel and Micron merely go their separate ways yet focus on the same market areas. A benefit could be if Intel and Micron pursue different market focus areas with some overlap while expanding to broader opportunities.

The latter scenario could be useful for moving the technology forward by giving it new and different opportunities. For example, some that favor Intel along with its ecosystem would prefer whatever Intel does next. Likewise, those that favor Micron and their ecosystem may influence the direction Micron goes.

Does this mean Micron and Intel are all done collaborating? Tough to say.

However, they still share a fabrication facility (fab) imFLASH in Lehi Utah.

Overall, I think this is a good move for both Intel and Micron once they get the second generation of 3D XPoint developed and into production for customer deployments. With Intel Micron 3D XPoint Evolving, lets see what’s next.

Ok, nuff said, for now.

Use Intel Optane NVMe U.2 SFF 8639 SSD drive in PCIe slot

Use NVMe U.2 SFF 8639 disk drive form factor SSD in PCIe slot

server storage I/O data infrastructure trends

Need to install or use an Intel Optane NVMe 900P or other Nonvolatile Memory (NVM) Express NVMe based U.2 SFF 8639 disk drive form factor Solid State Device (SSD) into PCIe a slot?

For example, I needed to connect an Intel Optane NVMe 900P U.2 SFF 8639 drive form factor SSD into one of my servers using an available PCIe slot.

The solution I used was an carrier adapter card such as those from Ableconn (PEXU2-132 NVMe 2.5-inch U.2 [SFF-8639] via Amazon.com among other global venues.

NVMe Tradecraft Refresher

NVMe is the protocol that is implemented with different topologies including local via PCIe using U.2 aka SFF-8639 (aka disk drive form factor), M.2 aka Next Generation Form Factor (NGFF) also known as "gum stick", along with PCIe Add in Card (AiC). NVMe accessed devices can be installed in laptops, ultra books, workstations, servers and storage systems using the various form factors. U.2 drives are also refereed to by some as PCIe drives in that the NVMe command set protocol is implemented using PCIe x4 physical connection to the devices. Jump ahead if you want to skip over the NVMe primer refresh material to learn more about U.2 8639 devices.

Various SSD device form factors and interfaces

In addition to form factor, NVMe devices can be direct attached and dedicated, rack and shared, as well as accessed via networks also known as fabrics such as NVMe over Fabrics.

NVMeoF FC-NVMe NVMe fabric SDDC
The many facets of NVMe as a front-end, back-end, direct attach and fabric

Context is important with NVMe in that fabric can mean NVMe over Fibre Channel (FC-NVMe) where the NVMe command set protocol is used in place of SCSI Fibre Channel Protocol (e.g. SCSI_FCP) aka FCP or what many simply know and refer to as Fibre Channel. NVMe over Fabric can also mean NVMe command set implemented over an RDMA over Converged Ethernet (RoCE) based network.

NVM and NVMe accessed flash SCM SSD storage

Another point of context is not to confuse Nonvolatile Memory (NVM) which are the storage or memory media and NVMe which is the interface for accessing storage (e.g. similar to SAS, SATA and others). As a refresher, NVM or the media are the various persistent memories (PM) including NVRAM, NAND Flash, 3D XPoint along with other storage class memories (SCM) used in SSD (in various packaging).

Learn more about 3D XPoint with the following resources:

View this piece here looking at NVM vs. NVMe and how one is the media where data is stored, while the other is an access protocol (e.g. NVMe). Also visit www.thenvmeplace.com to view additional NVMe tips, tools, technologies, and related resources.

NVMe U.2 SFF-8639 aka 8639 SSD

On quick glance, an NVMe U.2 SFF-8639 SSD may look like a SAS small form factor (SFF) 2.5" HDD or SSD. Also, keep in mind that HDD and SSD with SAS interface have a small tab to prevent inserting them into a SATA port. As a reminder, SATA devices can plug into SAS ports, however not the other way around which is what the key tab function does (prevents accidental insertion of SAS into SATA). Looking at the left-hand side of the following image you will see an NVMe SFF 8639 aka U.2 backplane connector which looks similar to a SAS port.

Note that depending on how implemented including its internal controller, flash translation layer (FTL), firmware and other considerations, an NVMe U.2 or 8639 x4 SSD should have similar performance to a comparable NVMe x4 PCIe AiC (e.g. card) device. By comparable device, I mean the same type of NVM media (e.g. flash or 3D XPoint), FTL and controller. Likewise generally an PCIe x8 should be faster than an x4, however more PCIe lanes does not mean more performance, its what’s inside and how those lanes are actually used that matter.

NVMe U.2 SFF 8639 Drive (Software Defined Data Infrastructure Essentials CRC Press)

With U.2 devices the key tab that prevents SAS drives from inserting into a SATA port is where four pins that support PCIe x4 are located. What this all means is that a U.2 8639 port or socket can accept an NVMe, SAS or SATA device depending on how the port is configured. Note that the U.2 8639 port is either connected to a SAS controller for SAS and SATA devices or a PCIe port, riser or adapter.

On the left of the above figure is a view towards the backplane of a storage enclosure in a server that supports SAS, SATA, and NVMe (e.g. 8639). On the right of the above figure is the connector end of an 8639 NVM SSD showing addition pin connectors compared to a SAS or SATA device. Those extra pins give PCIe x4 connectivity to the NVMe devices. The 8639 drive connectors enable a device such as an NVM, or NAND flash SSD to share a common physical storage enclosure with SAS and SATA devices, including optional dual-pathing.

More PCIe lanes may not mean faster performance, verify if those lanes (e.g. x4 x8 x16 etc) are present just for mechanical (e.g. physical) as well as electrical (they are also usable) and actually being used. Also, note that some PCIe storage devices or adapters might be for example an x8 for supporting two channels or devices each at x4. Likewise, some devices might be x16 yet only support four x4 devices.

NVMe U.2 SFF 8639 PCIe Drive SSD FAQ

Some common questions pertaining NVMe U.2 aka SFF 8639 interface and form factor based SSD include:

Why use U.2 type devices?

Compatibility with what’s available for server storage I/O slots in a server, appliance, storage enclosure. Ability to mix and match SAS, SATA and NVMe with some caveats in the same enclosure. Support higher density storage configurations maximizing available PCIe slots and enclosure density.

Is PCIe x4 with NVMe U.2 devices fast enough?

While not as fast as a PCIe AiC that fully supports x8 or x16 or higher, an x4 U.2 NVMe accessed SSD should be plenty fast for many applications. If you need more performance, then go with a faster AiC card.

Why not go with all PCIe AiC?

If you need the speed, simplicity, have available PCIe card slots, then put as many of those in your systems or appliances as possible. Otoh, some servers or appliances are PCIe slot constrained so U.2 devices can be used to increase the number of devices attached to a PCIe backplane while also supporting SAS, SATA based SSD or HDDs.

Why not use M.2 devices?

If your system or appliances supports NVMe M.2 those are good options. Some systems even support a combination of M.2 for local boot, staging, logs, work and other storage space while PCIe AiC are for performance along with U.2 devices.

Why not use NVMeoF?

Good question, why not, that is, if your shared storage system supports NVMeoF or FC-NVMe go ahead and use that, however, you might also need some local NVMe devices. Likewise, if yours is a software-defined storage platform that needs local storage, then NVMe U.2, M.2 and AiC or custom cards are an option. On the other hand, a shared fabric NVMe based solution may support a mixed pool of SAS, SATA along with NVMe U.2, M.2, AiC or custom cards as its back-end storage resources.

When not to use U.2?

If your system, appliance or enclosure does not support U.2 and you do not have a need for it. Or, if you need more performance such as from an x8 or x16 based AiC, or you need shared storage. Granted a shared storage system may have U.2 based SSD drives as back-end storage among other options.

How does the U.2 backplane connector attach to PCIe?

Via enclosures backplane, there is either a direct hardwire connection to the PCIe backplane, or, via a connector cable to a riser card or similar mechanism.

Does NVMe replace SAS, SATA or Fibre Channel as an interface?

The NVMe command set is an alternative to the traditional SCSI command set used in SAS and Fibre Channel. That means it can replace, or co-exist depending on your needs and preferences for access various storage devices.

Who supports U.2 devices?

Dell has supported U.2 aka PCIe drives in some of their servers for many years, as has Intel and many others. Likewise, U.2 8639 SSD drives including 3D Xpoint and NAND flash-based are available from Intel among others.

Can you have AiC, U.2 and M.2 devices in the same system?

If your server or appliance or storage system support them then yes. Likewise, there are M.2 to PCIe AiC, M.2 to SATA along with other adapters available for your servers, workstations or software-defined storage system platform.

NVMe U.2 carrier to PCIe adapter

The following images show examples of mounting an Intel Optane NVMe 900P accessed U.2 8639 SSD on an Ableconn PCIe AiC carrier. Once U.2 SSD is mounted, the Ableconn adapter inserts into an available PCIe slot similar to other AiC devices. From a server or storage appliances software perspective, the Ableconn is a pass-through device so your normal device drivers are used, for example VMware vSphere ESXi 6.5 recognizes the Intel Optane device, similar with Windows and other operating systems.

Here are some Amazon.com links to various Intel Optane NVMe 3D XPoint based SSDs in different packaging form factors:

Here are some Amazon.com links to various Intel and other vendor NAND flash based NVMe accessed SSDs including U.2, M.2 and AiC form factors:

Note in addition to carriers to adapt U.2 8639 devices to PCIe AiC form factor and interfaces, there are also M.2 NGFF to PCIe AiC among others. An example is the Ableconn M.2 NGFF PCIe SSD to PCI Express 3.0 x4 Host Adapter Card.

In addition to Amazon.com, Newegg.com, Ebay and many other venues carry NVMe related technologies.
The Intel Optane NVMe 900P are newer, however the Intel 750 Series along with other Intel NAND Flash based SSDs are still good price performers and as well as provide value. I have accumulated several Intel 750 NVMe devices over past few years as they are great price performers. Check out this related post Get in the NVMe SSD game (if you are not already).

What This All Means

NVMe accessed storage is in your future, however there are various questions to address including exploring your options for type of devices, form factors, configurations among other topics. Some NVMe accessed storage is direct attached and dedicated in laptops, ultrabooks, workstations and servers including PCIe AiC, M.2 and U.2 SSDs, while others are shared networked aka fabric based. NVMe over fabric (e.g. NVMeoF) includes RDMA over converged Ethernet (RoCE) as well as NVMe over Fibre Channel (e.g. FC-NVMe). Networked fabric accessed NVMe access of pooled shared storage systems and appliances can also include internal NVMe attached devices (e.g. as part of back-end storage) as well as other SSDs (e.g. SAS, SATA).

General wrap-up (for now) NVMe U.2 8639 and related tips include:

  • Verify the performance of the device vs. how many PCIe lanes exist
  • Update any applicable BIOS/UEFI, device drivers and other software
  • Check the form factor and interface needed (e.g. U.2, M.2 / NGFF, AiC) for a given scenario
  • Look carefully at the NVMe devices being ordered for proper form factor and interface
  • With M.2 verify that it is an NVMe enabled device vs. SATA

    NVMe Wont Replace Flash By Itself They Complement Each Other

    NVMe Wont Replace Flash By Itself They Complement Each Other

    server storage I/O data infrastructure trends

    Updated 2/2/2018

    NVMe Wont Replace Flash By Itself They Complement Each Other

    >various NVM flash and SSD devices
    Various Solid State Devices (SSD) including NVMe, SAS, SATA, USB, M.2

    There has been some recent industry marketing buzz generated by a startup to get some attention by claiming via a study sponsored by including the startup that Non-Volatile Memory (NVM) Express (NVMe) will replace flash storage. Granted, many IT customers as well as vendors are still confused by NVMe thinking it is a storage medium as opposed to an interface used for accessing fast storage devices such as nand flash among other solid state devices (SSDs). Part of that confusion can be tied to common SSD based devices rely on NVM that are persistent memory retaining data when powered off (unlike the memory in your computer).

    NVMe is an access interface and protocol

    Instead of saying NVMe will mean the demise of flash, what should or could be said however some might be scared to say it is that other interfaces and protocols such as SAS (Serial Attached SCSI), AHCI/SATA, mSATA, Fibre Channel SCSI Protocol aka FCP aka simply Fibre Channel (FC), iSCSI and others are what can be replaced by NVMe. NVMe is simply the path or roadway along with traffic rules for getting from point a (such as a server) to point b (some storage device or medium e.g. flash SSD). The storage medium is where data is stored such as magnetic for Hard Disk Drive (HDD) or tape, nand flash, 3D XPoint, Optane among others.

    NVMe and NVM better together

    NVMe and NVM including flash are better together

    The simple quick get to the point is that NVMe (e.g. Non Volatile Memory aka NVM Express [NVMe]) is an interface protocol (like SAS/SATA/iSCSI among others) used for communicating with various nonvolatile memory (NVM) and solid state device (SSDs). NVMe is how data gets moved between a computer or other system and the NVM persistent memory such as nand flash, 3D XPoint, Spintorque or other storage class memories (SCM).

    In other words, the only thing NVMe will, should, might or could kill off would be the use of some other interface such as SAS, SATA/AHCI, Fibre Channel, iSCSI along with propritary driver or protocols. On the other hand, given the extensibility of NVMe and how it can be used in different configurations including as part of fabrics, it is an enabler for various NVMs also known as persistent memories, SCMs, SSDs including those based on NAND flash as well as emerging 3D XPoint (or Intel version) among others.

    What This All Means

    Context matters for example, NVM as the medium compared to NVMe as the interface and access protocols. With context in mind you can compare like or similar apples to apples such as nand flash, MRAM, NVRAM, 3D XPoint, Optane among other persistent memories also known as storage class memories, NVMs and SSDs. Likewise with context in mind NVMe can be compared to other interfaces and protocols such as SAS, SATA, PCIe, mSATA, Fibre Channel among others. The following puts all of this into context including various packaging options, interfaces and access protocols, functionality and media.

    NVMe is the access for NVM flash
    Putting IT all together

    Will NVMe kill off flash? IMHO no not by itself, however NVMe combined with some other form of NVM, SCM, persistent memory as a storage medium may eventually combine as an alternative to NVMe and flash (or SAS/SATA and flash). However, for now at least for many applications, NVMe is in your future (along with flash among other storage mediums), the questions include when, where, why, how, with what among other questions (and answers). NVMe wont replace flash by itself (at least yet) as they complement each other.

    Keep in mind, if NVMe is the answer, what are the questions.

    Ok, nuff said, for now.

    If NVMe is the answer, what are the questions?

    If NVMe is the answer, what are the questions?

    If NVMe is the answer, then what are the various questions that should be asked?

    Some common questions that NVMe is the answer to include what is the difference between NVM and NVMe?

    Is NVMe only for servers, does NVMe require fabrics and what benefit is NVMe beyond more IOPs.

    Lets take a look at some of these common NVMe conversations and other questions.

    Main Features and Benefits of NVMe

    Some of the main feature and benefits of NVMe among others include:

      • Lower latency due to improve drivers and increased queues (and queue sizes)
      • Lower CPU used to handle larger number of I/Os (more CPU available for useful work)
      • Higher I/O activity rates (IOPS) to boost productivity unlock value of fast flash and NVM
      • Bandwidth improvements leveraging various fast PCIe interface and available lanes
      • Dual-pathing of devices like what is available with dual-path SAS devices
      • Unlock the value of more cores per processor socket and software threads (productivity)
      • Various packaging options, deployment scenarios and configuration options
      • Appears as a standard storage device on most operating systems
      • Plug-play with in-box drivers on many popular operating systems and hypervisors

    NVM and Media memory matters

    Whats the differences between NVM and NVMe? Non-Volatile Memory (NVM) which as its name implies is persistent electronic memory medium where data is stored. Today you commonly know about NVMs as NAND flash Solid State Devices (SSD), along with NVRAM among others emerging storage class memories (SCM).

    Emerging SCM such as 3D XPoint among other mediums (or media if you prefer) have the premises of boosting both read and write performance beyond traditional NAND flash, closer to DRAM, while having durability also closer to DRAM. For now let’s set the media and mediums aside and get back to how they or will be accessed as well as used.

    server storage I/O NVMe fundamentals

    Server and Storage I/O Media access matters

    NVM Express (e.g. NVMe) is a standard industry protocol for accessing NVM media (SSD and flash devices, storage system, appliances). If NVMe is the answer, then depending on your point of view, NVMe can be (or is) a replacement (today or in the future) for AHCI/SATA, Serial Attached SCSI (SAS). What this means is that NVMe can coexist or replace other block SCSI protocol implementations (e.g. Fibre Channel FCP aka FCP, iSCSI, SRP) as well as NBD (among others).

    Similar to the SCSI command set that is implemented on different networks (e.g. iSCSI (IP), FCP (Fibre Channel), SRP (InfiniBand), SAS) NVMe as a protocol is now implemented using PCIe with form factors of add-in cards (AiC), M.2 (e.g. gum sticks aka next-gen form factor or NGFF) as well as U.2 aka 8639 drive form factors. There are also the emerging NVMe over Fabrics variants including FC-NVMe (e.g. NVMe protocol over Fibre Channel) which is an alternative to SCSI_FCP (e.g. SCSI on Fibre Channel). An example of a PCIe AiC that I have include the Intel 750 400GB NVMe (among others). You should be able to find the Intel among other NVMe devices from your prefered vendor as well as different venues including Amazon.com.

    The following image shows an NVMe U.2 (e.g. 8639) drive form factor device that from a distance looks like a SAS device and connector. However looking closer some extra pins or connectors that present a PCIe Gen 3 x4 (4 PCIe lanes) connection from the server or enclosure backplane to the devices. These U.2 devices plug into 8639 slots (right) that look like a SAS slot that can also accommodate SATA. Remember, SATA can plug into SAS, however not the other way around.

    NVMe U.2 8639 driveNVMe 8639 slot
    Left NVMe U.2 drive showing PCIe x4 connectors, right, NVMe U.2 8639 connector

    What NVMe U.2 means is that the 8639 slots can be used for 12Gbps SAS, 6Gbps SATA or x4 PCIe-based NVMe. Those devices in turn attach to their respective controllers (or adapters) and device driver software protocol stack. Several servers have U.2 or 8639 drive slots either in 2.5” or 1.8” form factors, sometimes these are also called or known as “blue” drives (or slots). The color coding simply helps to keep track of what slots can be used for different things.

    Navigating your various NVMe options

    If NVMe is the answer, then some device and component options are as follows.

    NVMe device components and options include:

      • Enclosures and connector port slots
      • Adapters and controllers
      • U.2, PCIe AIC and M.2 devices
      • Shared storage system or appliances
      • PCIe and NVMe switches

    If NVMe is the answer, what to use when, where and why?

    Why use an U.2 or 8639 slot when you could use PCIe AiC? Simple, your server or storage system may be PCIe slot constrained, yet have more available U.2 slots. There are U.2 drives from various vendors including Intel and Micro, as well as servers from Dell, Intel and Lenovo among many others.

    Why and when would you use an NVMe M.2 device? As a local read/write cache, or perhaps a boot and system device on servers or appliances that have M.2 slots. Many servers and smaller workstations including Intel NUC support M.2. Likewise, there are M.2 devices from many different vendors including Micron, Samsung among others.

    Where and why would you use NVMe PCIe AiC? Whenever you can and if you have enough PCIe slots of the proper form factor, mechanical and electrical (e.g. x1, x4, x8, x16) to support a particular card.

    Can you mix and match different types of NVMe devices on the same server or appliance? As long as the physical server and its software (BIOS/UEFI, operating system, hypervisors, drivers) support it yes. Most server and appliance vendors support PCIe NVMe AiCs, however, pay attention to if they are x4, x8 both mechanical as well as electrical. Also, verify operating system and hypervisor device driver support. PCIe NVMe AiCs are available from Dell, Intel, Micron and many other vendors.

    Networking with your Server and NVMe Storage

    Keep in mind that context is important when discussing NVMe as there are devices for attaching as the back-end to servers, storage systems or appliances, as well as for front-end attachment (e.g. for attaching storage systems to servers). NVMe devices can also be internal to a server or storage system and appliance, or, accessible over a network. Think of NVMe as an upper-level command set protocol like SCSI that gets implemented on different networks (e.g. iSCSI, FCP, SRP).

    How can NVMe use PCIe as a transport to use devices that are outside of a server? Different vendors have PCIe adapter cards that support longer distances (few meters) to attach to devices. For example, Dell EMC DSSD has a special dual port (two x4 ports) that are PCIe x8 cards for attachment to the DSSD shared SSD devices.

    Note that there are also PCIe switches similar to SAS and InfiniBand among other switches. However just because these are switches, does not mean they are your regular off the shelf network type switch that your networking folks will know what to do with (or want to manage).

    The following example shows a shared storage system or appliance being accessed by servers using traditional block, NAS file or object protocols. In this example, the storage system or appliance has implemented NVMe devices (PCIe AiC, M.2, U.2) as part of their back-end storage. The back-end storage might be all NVMe, or a mix of NVMe, SAS or SATA SSD and perhaps some high-capacity HDD.

    NVMe and server storage access
    Servers accessing shared storage with NVMe back-end devices

    NVMe and server storage access via PCIe
    NVMe PCIe attached (via front-end) storage with various back-end devices

    In addition to shared PCIe-attached storage such as Dell EMC DSSD similar to what is shown above, there are also other NVMe options. For example, there are industry initiatives to support the NVMe protocol to use shared storage over fabric networks. There are different fabric networks, they range from RDMA over Converged Ethernet (RoCE) based as well as Fibre Channel NVME (e.g. FC-NVME) among others.

    An option that on the surface may not seem like a natural fit or leverage NVMe to its fullest is simply adding NVMe devices as back-end media to existing arrays and appliances. For example, adding NVMe devices as the back-end to iSCSI, SAS, FC, FCoE or other block-based, NAS file or object systems.

    NVMe and server storage access via shared PCIe
    NVMe over a fabric network (via front-end) with various back-end devices

    A common argument against using legacy storage access of shared NVMe is along the lines of why would you want to put a slow network or controller in front of a fast NVM device? You might not want to do that, or your vendor may tell you many reasons why you don’t want to do it particularly if they do not support it. On the other hand, just like other fast NVM SSD storage on shared systems, it may not be all about 100% full performance. Rather, for some environments, it might be about maximizing connectivity over many interfaces to faster NVM devices for several servers.

    NVMe and server storage I/O performance

    Is NVMe all about boosting the number of IOPS? NVMe can increase the number of IOPS, as well as support more bandwidth. However, it also reduces response time latency as would be expected with an SSD or NVM type of solution. The following image shows an example of not surprisingly an NVMe PCIe AiC x4 SSD outperforming (more IOPs, lower response time) compared to a 6Gb SATA SSD (apples to oranges). Also keep in mind that best benchmark or workload tool is your own application as well as your performance mileage will vary.

    NVMe using less CPU per IOP
    SATA SSD vs. NVMe PCIe AiC SSD IOPS, Latency and CPU per IOP

    The above image shows the lower amount of CPU per IOP given the newer, more streamlined driver and I/O software protocol of NVMe. With NVMe there is less overhead due to the new design, more queues and ability to unlock value not only in SSD also in servers with more sockets, cores and threads.

    What this means is that NVMe and SSD can boost performance for activity (TPS, IOPs, gets, puts, reads, writes). NVMe can also lower response time latency while also enabling higher throughput bandwidth. In other words, you get more work out of your servers CPU (and memory). Granted SSDs have been used for decades to boost server performance and in many cases, delay an upgrade to a newer faster system by getting more work out of them (e.g. SSD marketing 202).

    NVMe maximizing your software license investments

    What may not be so obvious (e.g. SSD marketing 404) is that by getting more work activity done in a given amount of time, you can also stretch your software licenses further. What this means is that you can get more out of your IBM, Microsoft, Oracle, SAP, VMware and other software licenses by increasing their effective productivity. You might already be using virtualization to increase server hardware efficiency and utilization to cut costs. Why not go further and boost productivity to increase your software license (as well as servers) effectiveness by using NVMe and SSDs?

    Note that fast applications need fast software, servers, drivers, I/O protocols and devices.

    Also just because you have NVMe present or PCIe does not mean full performance, similar to how some vendors put SSDs behind their slow controllers and saw, well slow performance. On the other hand vendors who had or have fast controllers (software, firmware, hardware) that were HDD or are even SSD performance constrained can see a performance boost.

    Additional NVMe and related tips

    If you have a Windows server and have not overridden, check your power plan to make sure it is not improperly set to balanced instead of high performance. For example using PowerShell issue the following command:

    PowerCfg -SetActive “381b4222-f694-41f0-9685-ff5bb260df2e”

    Another Windows related tip if you have not done so is enable task manager disk stats by issuing from a command line “diskperf –y”. Then display task manager and performance and see drive performance.

    Need to benchmark, validate, compare or test an NVMe, SSD (or even HDD) device or system, there are various tools and workloads for different scenarios. Likewise those various tools can be configured for different activity to reflect your needs (and application workloads). For example, Microsoft Diskspd, fio.exe, iometer and vdbench sample scripts are shown here (along with results) as a starting point for comparison or validation testing.

    Does M.2. mean you have NVMe? That depends as some systems implement M.2 with SATA, while others support NVMe, read the fine print or ask for clarification.

    Do all NVMe using PCIe run at the same speed? Not necessarily as some might be PCIe x1 or x4 or x8. Likewise some NVMe PCIe cards might be x8 (mechanical and electrical) yet split out into a pair of x4 ports. Also keep in mind that similar to a dual port HDD, NVMe U.2 drives can have two paths to a server, storage system controller or adapter, however both might not be active at the same time. You might also have a fast NVMe device attached to a slow server or storage system or adapter.

    Who to watch and keep an eye on in the NVMe ecosystem? Besides those mentioned above, others to keep an eye on include Broadcom, E8, Enmotus Fuzedrive (micro-tiering software), Excelero, Magnotics, Mellanox, Microsemi (e.g. PMC Sierra), Microsoft (Windows Server 2016 S2D + ReFS + Storage Tiering), NVM Express trade group, Seagate, VMware (Virtual NVMe driver part of vSphere ESXi in addition to previous driver support) and WD/Sandisk among many others.

    What This All Means

    NVMe is in your future, that was the answer, however there are the when, where, how, with what among other questions to be addressed. One of the great things IMHO about NVMe is that you can have it your way, where and when you need it, as a replacement or companion to what you have. Granted that will vary based on your preferred vendors as well as what they support today or in the future.

    If NVMe is the answer, Ask your vendor when they will support NVMe as a back-end for their storage systems, as well as a front-end. Also decide when will your servers (hardware, operating systems hypervisors) support NVMe and in what variation. Learn more why NVMe is the answer and related topics at www.thenvmeplace.com

    Get in the NVMe SSD game (if you are not already) with Intel 750 among others

    Get in the NVMe SSD game (if you are not already)

    Get in the NVMe SSD game. If you are or have talked the Non Volatile Memory (NVM) and NVM Express (NVMe) flash SSD talk, however have not yet done the walk, there are some good opportunities to do so.

    One example how to start walking the talk is get something like the Intel 750 400GB NVMe PCIe Add in Card (AiC) which you should be able to find on different venues including Amazon for $400 USD or less (recently saw the 400GB version for about $309 USD delivered).

    Of course the question might then be what to do with a NVMe device when you get it which besides running your applications on it, you can find some benchmark and workload generator tools, scripts and examples here.

    NVMe ssd storage
    Various NVM flash SSD including NVMe devices

    Sure there are newer, more expensive, higher capacity cards, some are general availability (GA) while others are on early preview or evaluation basis.

    However a good value, cost-effective way to get into the NVMe game, or expand your footprint are devices such as the Intel 750.

    I have some of these cards and they have been great for use with various workloads. The Intel 750 cards are plug and play in various systems including my TS140s among larger robust servers running Windows Server (2012 R2, 2016 TP5), Ubuntu (various) and VMware ESXi (various).

    There are in the box drivers for these Intel 750 cards, however to get a little more performance recommend visiting the Intel site, get the SSD tools, update the firmware on the cards if needed, as well as try the Intel vs. native drivers.

    There are many vendors with NVMe PCIe cards, as well as U.2/SFF 8639 drives and M.2 mini-cards including Intel, Micron, Seagate, WD among many others

    What This All Means

    Time to get in the NVMe game if you have not already done so moving from talking the talk to walking the talk. With cost of early generation NVMe devices such as the Intel 750 among others there are great opportunities to get started. On the other hand if you are already using NVMe, there are some good opportunities to add extra NVMe based SSD to other servers or systems.

    Speaking of NVMe talk, join me and others on a panel (Session 303) moderated by Dr. Jay Metz (@drjmetz) August 11th at Flash Memory Summit where we will discuss NVMe including NVMe over fabric networks (e.g. moving beyond the PCIe bus). Also keep in mind, with NVMe the question is not if, rather when, where, why, how with what and how to coexist and leverage existing technologies, hardware, software and people skill sets.

    The NVMe Place resources and NVM including SCM, PMEM, Flash

    NVMe place includes Non Volatile Memory (NVM) including nand flash, storage class memories (SCM), persistent memories (PM) are storage memory mediums while NVM Express (NVMe) is an interface for accessing NVM. This NVMe resources page is a companion to The SSD Place which has a broader Non Volatile Memory (NVM) focus including flash among other SSD topics. NVMe is a new server storage I/O access method and protocol for fast access to NVM based storage and memory technologies. NVMe is an alternative to existing block based server storage I/O access protocols such as AHCI/SATA and SCSI/SAS devices commonly used for access Hard Disk Drives (HDD) along with SSD among other things.

    Server Storage I/O NVMe PCIe SAS SATA AHCI
    Comparing AHCI/SATA, SCSI/SAS and NVMe all of which can coexist to address different needs.

    Leveraging the standard PCIe hardware interface, NVMe based devices (that have an NVMe controller) can be accessed via various operating systems (and hypervisors such as VMware ESXi) with both in the box drivers or optional third-party device drivers. Devices that support NVMe can be 2.5″ drive format packaged that use a converged 8637/8639 connector (e.g. PCIe x4) coexisting with SAS and SATA devices as well as being add-in card (AIC) PCIe cards supporting x4, x8 and other implementations. Initially, NVMe is being positioned as a back-end to servers (or storage systems) interface for accessing fast flash and other NVM based devices.

    NVMe as a “back-end” I/O interface for NVM storage media

    NVMe as front-end server storage I/O interface
    NVMe as a “front-end” interface for servers or storage systems/appliances

    NVMe has also been shown to work over low latency, high-speed RDMA based network interfaces including RoCE (RDMA over Converged Ethernet) and InfiniBand (read more here, here and here involving Mangstor, Mellanox and PMC among others). What this means is that like SCSI based SAS which can be both a back-end drive (HDD, SSD, etc) access protocol and interface, NVMe can also being used for back-end can also be used as a front-end of server to storage interface like how Fibre Channel SCSI_Protocol (aka FCP), SCSI based iSCSI, SCSI RDMA Protocol via InfiniBand (among others) are used.

    NVMe features

    Main features of NVMe include among others:

    • Lower latency due to improve drivers and increased queues (and queue sizes)
    • Lower CPU used to handle larger number of I/Os (more CPU available for useful work)
    • Higher I/O activity rates (IOPs) to boost productivity unlock value of fast flash and NVM
    • Bandwidth improvements leveraging various fast PCIe interface and available lanes
    • Dual-pathing of devices like what is available with dual-path SAS devices
    • Unlock the value of more cores per processor socket and software threads (productivity)
    • Various packaging options, deployment scenarios and configuration options
    • Appears as a standard storage device on most operating systems
    • Plug-play with in-box drivers on many popular operating systems and hypervisors

    Non-Volatile Memory (NVM) Express (NVMe) continues to evolve as a technology for enabling and improving server storage I/O for NVM including nand flash SSD storage. NVMe streamline performance enabling more work to be done (e.g. IOPs), data to be moved (bandwidth) at a lower response time using less CPU.

    NVMe and SATA flash SSD performance

    The above figure is a quick look comparing nand flash SSD being accessed via SATA III (6Gbps) on the left and NVMe (x4) on the right. As with any server storage I/O performance comparisons there are many variables and take them with a grain of salt. While IOPs and bandwidth are often discussed, keep in mind that with the new protocol, drivers and device controllers with NVMe that streamline I/O less CPU is needed.

    Intel Micron 3D XPoint server storage NVM SCM PM SSD

    3D XPoint server storage class memory SCM


    Storage I/O trends

    Updated 1/31/2018

    Intel Micron 3D XPoint server storage NVM SCM PM SSD.

    This is the second of a three-part series on the recent Intel and Micron 3D XPoint server storage memory announcement. Read Part I here and Part III here.

    Is this 3D XPoint marketing, manufacturing or material technology?

    You can’t have a successful manufactured material technology without some marketing, likewise marketing without some manufactured material would be manufactured marketing. In the case of 3D XPoint and its announcement launch, their real technology shown, granted it was only wafer and dies as opposed to an actual DDR4 DIMM or PCIe Add In Card (AIC) or drive form factor Solid State Device (SSD) product. On the other hand, on a relative comparison basis, even though there is marketing collateral available to learn more from, this was far from a over the big-top made for TV or web circus event, which can be a good thing.


    Wafer unveiled containing 3D XPoint 128 Gb dies

    Who will get access to 3D XPoint?

    Initially 3D XPoint production capacity supply will be for the two companies to offer early samples to their customers later this year with general production slated for 2016 meaning early real customer deployed products starting sometime in 2016.

    Is it NAND or NOT?

    3D XPoint is not NAND flash, it is also not NVRAM or DRAM, it’s a new class of NVM that can be used for server class main memory with persistency, or as persistent data storage among other uses (cell phones, automobiles, appliances and other electronics). In addition, 3D XPoint is more durable with a longer useful life for writing and storing data vs. NAND flash.

    Why is 3D XPoint important?

    As mentioned during the Intel and Micron announcement, there have only been seven major memory technologies introduced since the transistor back in 1947, granted there have been many variations along with generational enhancements of those. Thus 3D XPoint is being positioned by Intel and Micron as the eighth memory class joining its predecessors many of which continue to be used today in various roles.


    Major memory classes or categories timeline

    In addition to the above memory classes or categories timeline, the following shows in more detail various memory categories (click on the image below to get access to the Intel interactive infographic).

    Intel History of Memory Infographic
    Via: https://intelsalestraining.com/memory timeline/ (Click on image to view)

    What capacity size is 3D XPoint?

    Initially the 3D XPoint technology is available in a 2 layer 128 bit (cell) per die capacity. Keep in mind that there are usually 8 bits to a byte resulting in 16 GByte capacity per chip initially. With density improvements, as well as increased stacking of layers, the number of cells or bits per die (e.g. what makes up a chip) should improve, as well as most implementations will have multiple chips in some type of configuration.

    What will 3D XPoint cost?

    During the 3D XPoint launch webinar Intel and Micron hinted that first pricing will be between current DRAM and NAND flash on a per cell or bit basis, however real pricing and costs will vary depending on how packaged for use. For example if placed on a DDR4 or different type of DIMM or on a PCIe Add In Card (AIC) or as a drive form factor SSD among other options will vary the real price. Likewise as with other memories and storage mediums, as production yields and volumes increase, along with denser designs, the cost per usable cell or bit can be expected to further improve.

    What This All Means

    DRAM which has been around for sometime has plenty of life left for many applications as does NAND flash including new 3D NAND, vNAND and other variations. For the next several years, there will be a co-existences between new and old NVM and DRAM among other memory technologies including 3D XPoint.

    Disclosure: Micron and Intel have been direct and/or indirect clients in the past via third-parties and partners, also I have bought and use some of their technologies direct and/or in-direct via their partners.

    Intel Micron unveil new 3D XPoint Non Volatie Memory NVM for servers storage

    3D XPoint NVM persistent memory PM storage class memory SCM


    Storage I/O trends

    Updated 1/31/2018

    This is the first of a three-part series on Intel Micron unveil new 3D XPoint Non Volatie Memory NVM for servers storage announcement. Read Part II here and Part III here.

    In a webcast the other day, Intel and Micron announced new 3D XPoint non-volatile memory (NVM) that can be used for both primary main memory (e.g. what’s in computers, serves, laptops, tablets and many other things) in place of Dynamic Random Access Memory (DRAM), for persistent storage faster than today’s NAND flash-based solid state devices (SSD), not to mention future hybrid usage scenarios. Note that this announcement while having the common term 3D in it is different from the earlier Intel and Micron announcement about 3D NAND flash (read more about that here).

    The big picture, why this type of NVM technology is needed

    Server and Storage I/O trends

    • Memory is storage and storage is persistent memory
    • No such thing as a data or information recession, more data being create, processed and stored
    • Increased demand is also driving density along with convergence across server storage I/O resources
    • Larger amounts of data needing to be processed faster (large amounts of little data and big fast data)
    • Fast applications need more and faster processors, memory along with I/O interfaces
    • The best server or storage I/O is the one you do not need to do
    • The second best I/O is one with least impact or overhead
    • Data needs to be close to processing, processing needs to be close to the data (locality of reference)


    Server Storage I/O memory hardware and software hierarchy along with technology tiers

    What did Intel and Micron announce?

    Intel SVP and General Manager Non-Volatile Memory solutions group Robert Crooke (Left) and Micron CEO D. Mark Durcan did the joint announcement presentation of 3D XPoint (webinar here). What was announced is the 3D XPoint technology jointly developed and manufactured by Intel and Micron which is a new form or category of NVM that can be used for both primary memory in servers, laptops, other computers among other uses, as well as for persistent data storage.

    Summary of 3D XPoint announcement

    • New category of NVM memory for servers and storage
    • Joint development and manufacturing by Intel and Micron in Utah
    • Non volatile so can be used for storage or persistent server main memory
    • Allows NVM to scale with data, storage and processors performance
    • Leverages capabilities of both Intel and Micron who have collaborated in the past
    • Performance Intel and Micron claim up to 1000x faster vs. NAND flash
    • Availability persistent NVM compared to DRAM with better durability (life span) vs. NAND flash
    • Capacity densities about 10x better vs. traditional DRAM
    • Economics cost per bit between dram and nand (depending on packaging of resulting products)

    What applications and products is 3D XPoint suited for?

    In general, 3D XPoint should be able to be used for many of the same applications and associated products that current DRAM and NAND flash-based storage memories are used for. These range from IT and cloud or managed service provider data centers based applications and services, as well as consumer focused among many others.


    3D XPoint enabling various applications

    In general, applications or usage scenarios along with supporting products that can benefit from 3D XPoint include among others’. Applications that need larger amounts of main memory in a denser footprint such as in-memory databases, little and big data analytics, gaming, wave form analysis for security, copyright or other detection analysis, life sciences, high performance compute and high-productivity compute, energy, video and content severing among many others.

    In addition, applications that need persistent main memory for resiliency, or to cut delays and impacts for planned or un-planned maintenance or having to wait for memories and caches to be warmed or re-populated after a server boot (or re-boot). 3D XPoint will also be useful for those applications that need faster read and write performance compared to current generations NAND flash for data storage. This means both existing and emerging applications as well as some that do not yet exist will benefit from 3D XPoint over time, like how today’s applications and others have benefited from DRAM used in Dual Inline Memory Module (DIMM) and NAND flash advances over the past several decades.

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

    What This All Means

    First, keep in mind that this is very early in the 3D XPoint technology evolution life-cycle and both DRAM and NAND flash will not be dead at least near term. Keep in mind that NAND flash appeared back in 1989 and only over the past several years has finally hit its mainstream adoption stride with plenty of market upside left.

    Nand flash SSD NVM SCM server storage I/O memory conversations

    Updated 8/31/19
    Server Storage I/O storageioblog SDDC SDDI Data Infrastructure trends

    The SSD Place NVM, SCM, PMEM, Flash, Optane, 3D XPoint, MRAM, NVMe Server, Storage, I/O Topics

    Now and then somebody asks me if I’m familiar with flash or nand flash Solid State Devices (SSD) along with other non-volatile memory (NVM) technologies and trends including NVM Express (NVMe).

    Having been involved with various types of SSD technology, products and solutions since the late 80s initially as a customer in IT (including as a lunch customer for DEC’s ESE20 SSD’s), then later as a vendor selling SSD solutions, as well as an analyst and advisory consultant cover the technologies, I tell the person asking, well, yes, of course.

    That gave me the idea as well as to help me keep track of some of the content and make it easy to find by putting it here in this post (which will be updated now and then).

    Thus this is a collection of articles, tips, posts, presentations, blog posts and other content on SSD including nand flash drives, PCIe cards, DIMMs, NVM Express (NVMe), hybrid and other storage solutions along with related themes.

    Also if you can’t find it here, you can always do a Google search like this or this to find some more material (some of which is on this page).

    Flash SSD Articles, posts and presentations

    The following are some of my tips, articles, blog posts, presentations and other content on SSD. Keep in mind that the question should not be if SSD are in your future, rather when, where, with what, from whom and how much. Also keep in mind that a bit of SSD as storage or cache in the right place can go a long way, while a lot of SSD will give you a benefit however also cost a lot of cash.
