Data Infrastructure Server Storage I/O Tradecraft Trends

Data Infrastructure Server Storage I/O Tradecraft Trends

Updated 1/17/2018

Data Infrastructure trends include server storage I/O network and associated tradecraft are your skills, experiences, insight as well as tricks of the trade, profession and job function (read more about what is a data infrastructure here).

This is the second of a two-part series exploring data infrastructure along with serve storage I/O and related tradecraft. Read part one of this series here.

Data Infrastructures
Data Infrastructure and IT Infrastructure Layers

As a refresher from part one, data infrastructure encompasses servers, storage, I/O and networking along with associated hardware, software, services and management tasks including data protection among others. Tradecraft is knowing about tools, technologies, and trends in your primary domain as well as adjacent focus areas. However, tradecraft is also about knowing how and when to use different technologies, tools with various techniques to address different scenarios.

Tradecraft Trends
Trends involving tradecraft include capturing existing experiences and skills from those who are about to retire or simply move on to something else, as well as learning for those new to IT or servers, storage, I/O, and data infrastructure hardware, software, and services. This means being able to find a balance of old and new tools, techniques, and technologies, including using things in new ways for different situations.

Part of expanding your tradecraft skill set is knowing when to use different tools, techniques, and technologies from proprietary and closed to open solutions, from tightly integrated to loosely integrated, to bundled and converged, or to a la carte or unbundled components, with do-it-yourself (DIY) integration.

Tradecraft also means being able to balance when to make a change of technology, tool, or technique for the sake of change vs. clinging to something comfortable or known, vs. leveraging old and new in new ways while enabling change without disrupting the data infrastructure environment or users of its services.

A couple of other trends include the convergence of people and positions within organizations that may have been in different silos or focus areas in the past. One example is the rise of Development Operations (also known as DevOps), where instead of separate development, administration, and operations areas, they are a combined entity. This might be déja vu for some of you who grew up and gained your tradecraft in similar types of organizations decades ago; for others, it may be something new.

Regarding fundamental tradecraft skills, if you are a hardware person it is wise to learn software; if you are a software person, it is advisable to acquire some hardware experience. Also, don’t be afraid to say “I do not know” or “it depends on on” when asked a question. This also means learning how information technology supports the needs of the business, as well as learning the technology the business uses.

Put another way, in addition to learning server storage I/O hardware and software tradecraft, also learn the basic tradecraft of the business your information systems are supporting. After all, the fundamental role of IT is to protect, preserve, and serve information that enables the company or organization; no business exists just to support IT.

Data Infrastructure Tool Box

How to develop tradecraft?
There are many ways, including reading this book along with the companion websites as well as other books, attending seminars and webinars, participating in forums and user groups, as well as having a test lab to learn and try things. Also, find a mentor you can learn from to help capture some of his or her tradecrafts, and if you are experienced, become a mentor to help others develop their tradecraft.

Toolbox tips, reminders, and recommendations:

  • Create a virtual, software-defined, and physical toolbox.
  • Include tip sheets, notes, hints, tricks, and shortcuts.
  • Leverage books, blogs, websites, tutorials, and related information.
  • Implement a lab or sandbox to try things out
  • Do some proof of concepts (POC) and gain more experience

Tradecraft Tips
Get some hands-on, behind-the-wheel time with various technologies to gain insight, perspective, and appreciation of what others are doing, as well as what is needed to make informed decisions about other areas. This also means learning from looking at demos, trying out software, tools, services, or using other ways to understand the solution. Knowing about the tools and technology is important; however, so too is knowing how to use a tool (techniques) and when along with where or for what. This means knowing the tools in your toolbox, but also knowing when, where, why, and how to use a given tool (or technology), along with techniques to use that tool by itself or with multiple other tools.

Additional tips and considerations include:

  • Expand your social and technical network into adjacent areas.
  • Get involved in user groups, forums, and other venues to learn and give back.
  • Listen, learn, and comprehend vs. only memorizing to pass a test.
  • Find a mentor to help guide you, and become a mentor to help others.
  • Collaborate, share, respect and be respected; the accolades will follow.
  • Evolve from focus on certificates or credentials to expansion of experiences.
  • Connect with others to expand your network

What this means

Remember that tradecraft is skills, experiences, tricks, and techniques along with knowing what as well as how to use various related tools as part of what it is that you are doing. Your data infrastructure tradecraft is (or should be):

  • Essential skills and experiences spanning different technologies and focus areas
  • Knowing various techniques to use new and old things in new as well as hybrid ways
  • Expanding awareness into adjacent areas around your current focus or interest areas
  • Leveraging comprehension, understanding application of what you know
  • Evolving with new knowledge, experiences, and insight about tools and techniques
  • Hardware, software, services, processes, practices, and management
  • From legacy to software-defined, cloud, virtual, and containers

Part of server storage I/O data infrastructure tradecraft is understanding what tools to use when, where, and why, not to mention knowing how to adapt with those tools, find new ones, or create your own.

Remember, if all you have is a hammer, everything starts to look like a nail. On the other hand, if you have more tools than you know what to do with, or how to use them, perhaps fewer tools are needed along with learning how to use them by enhancing your skillset and tradecraft.

In-between the known data infrastructure server, storage, I/O network, converged infrastructure (CI), hyper-converged infrastructure (HCI), Docker and other containers, cloud, hardware software-defined known, and unknown is your tradecraft. The narrow the gap between the known and the unknown as well as how to apply your experience is the diversity of your tradecraft.

Ok, nuff said, for now.

What Does Converged Infrastructure CI Hyperconverged HCI Mean to Storage I/O?

What Does CI and HCI Mean to Storage I/O?

server storage I/O trends

Updated 1/17/2018

Converged Infrastructure (CI), Hyperconverged Infrastructure (HCI) along with Cluster or Cloud In Box (CIB) are popular trend topics that have gained both industry and customer adoption as part of data infrastructures. Data Infrastructures exists to support business, cloud and information technology (IT) among other applications that transform data into information or services. The fundamental role of legacy and software defined data infrastructures (SDDI) is to provide a platform environment for applications and data that is resilient, flexible, scalable, agile, efficient as well as cost-effective.

Software Defined Data Infrastructure overview

Business, IT Information, Data and other Infrastructures

Put another way, data infrastructures exist to protect, preserve, process, move, secure and serve data as well as their applications for information services delivery. Technologies that make up data infrastructures include hardware, software, cloud or managed services, servers, storage, I/O and networking along with people, processes, policies along with various tools spanning legacy, software-defined virtual, containers and cloud.

As part of data infrastructures, CI, CIB and HCI enable simplified deployment of resources (servers, storage, I/O networking, hardware, software) across different environments. What do these various approaches (CI, HCI, CiB) mean for a hyperconverged (and converged) storage environment? What are the key concerns and considerations related specifically to storage? Most importantly, how do you know that you’re asking the right questions in order to get to the right answers?

Join me on March 15 at 10:00 AM PT for a live (free) webinar organized by the Storage Network Industry Association (SNIA) Ethernet Storage Forum (ESF). In this webinar (What Does Hyperconverged Mean to Storage) I will be joined by SNIA ESF chair John Kim of Mellanox to discuss moving beyond the hype to prepare, plan and make decisions for deploying CI, CiB and HCI.

Some of the server, storage I/O and related topics we will be discussing during the webcast include:

  • What are the storage considerations for CI, CIB and HCI
  • Fast applications and fast servers need fast server storage I/O

    Windows Server 2016 and Active Directory
    Whats New and How to Plan for Migration

    Windows Server 2016 is expected to GA this fall and is a modernized version of the Microsoft operating system that includes new capabilities such as Active Directory (AD) enhancements. AD is critical to organizational operations providing control and secure access to data, networks, servers, storage and more from physical, virtual and cloud (public and hybrid). But over time, organizations along with their associated IT infrastructures have evolved due to mergers, acquisitions, restructuring and general growth. As a result, yesterday’s AD deployments may look like they did in the past while using new technology (e.g. in old ways). Now is the time to start planning for how you will optimize your AD environment using new tools and technologies such as those in Windows Server 2016 and AD in new ways. Optimizing AD means having a new design, performing cleanup and restructuring prior to migration vs. simply moving what you have. Join us for this interactive webinar to begin planning your journey to Windows Server 2016 and a new optimized AD deployment that is flexible, scalable and elastic, and enables resilient infrastructures. You will learn:

    • What’s new in Windows Server 2016 and how it impacts your AD
    • Why an optimized AD is critical for IT environments moving forward
    • How to gain insight into your current AD environment
    • AD restructuring planning considerations

    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).

    Twitter hash tag #3DXpoint

    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.


    Robert Crooke (Left) and Mark Durcan (Right)

    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.

    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. Continue reading Part II here and Part III here of this three-part series on Intel and Micron 3D XPoint along with more analysis and commentary.

    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.

    Server Storage I/O Benchmark Performance Resource Tools

    Server Storage I/O Benchmarking Performance Resource Tools

    server storage I/O trends

    Updated 1/23/2018

    Server storage I/O benchmark performance resource tools, various articles and tips. These include tools for legacy, virtual, cloud and software defined environments.

    benchmark performance resource tools server storage I/O performance

    The best server and storage I/O (input/output operation) is the one that you do not have to do, the second best is the one with the least impact.

    server storage I/O locality of reference

    This is where the idea of locality of reference (e.g. how close is the data to where your application is running) comes into play which is implemented via tiered memory, storage and caching shown in the figure above.

    Cloud virtual software defined storage I/O

    Server storage I/O performance applies to cloud, virtual, software defined and legacy environments

    What this has to do with server storage I/O (and networking) performance benchmarking is keeping the idea of locality of reference, context and the application workload in perspective regardless of if cloud, virtual, software defined or legacy physical environments.

    VMware VVOLs storage I/O fundementals (Part 1)

    VMware VVOL’s storage I/O fundamentals (Part I)

    Note that this is a three part series with the first piece here (e.g. Are VMware VVOL’s in your virtual server and storage I/O future?), the second piece here (e.g.VMware VVOL’s and storage I/O fundamentals Part 1) and the third piece here (e.g. VMware VVOL’s and storage I/O fundamentals Part 2).

    Some of you may already be participating in the VMware beta of VVOL involving one of the initial storage vendors also in the beta program.

    Ok, now let’s go a bit deeper, however if you want some good music to listen to while reading this, check out @BruceRave GoDeepMusic.Net and shows here.

    Taking a step back, digging deeper into Storage I/O and VVOL’s fundamentals

    Instead of a VM host accessing its virtual disk (aka VMDK) which is stored in a VMFS formatted data store (part of ESXi hypervisor) built on top of a SCSI LUN (e.g. SAS, SATA, iSCSI, Fibre Channel aka FC, FCoE aka FC over Ethernet, IBA/SRP, etc) or an NFS file system presented by a storage system (or appliance), VVOL’s push more functionality and visibility down into the storage system. VVOL’s shift more intelligence and work from the hypervisor down into the storage system. Instead of a storage system simply presenting a SCSI LUN or NFS mount point and having limited (coarse) to no visibility into how the underlying storage bits, bytes as well as blocks are being used, storage systems gain more awareness.

    Keep in mind that even files and objects still get ultimately mapped to pages and blocks aka sectors even on nand flash-based SSD’s. However also keep an eye on some new technology such as the Seagate Kinetic drive that instead of responding to SCSI block based commands, leverage object API’s and associated software on servers. Read more about these emerging trends here and here at objectstoragecenter.com.

    With a normal SCSI LUN the underlying storage system has no knowledge of how the upper level operating system, hypervisor, file system or application such as a database (doing raw IO) is allocating the pages or blocks of memory aka storage. It is up to the upper level storage and data management tools to map from objects and files to the corresponding extents, pages and logical block address (LBA) understood by the storage system. In the case of a NAS solution, there is a layer of abstractions placed over the underlying block storage handling file management and the associated file to LBA mapping activity.

    Storage I/O basics
    Storage I/O and IOP basics and addressing: LBA’s and LBN’s

    Getting back to VVOL, instead of simply presenting a LUN which is essentially a linear range of LBA’s (think of a big table or array) that the hypervisor then manages data placement and access, the storage system now gains insight into what LBA’s correspond to various entities such as a VMDK or VMX, log, clone, swap or other VMware objects. With this more insight, storage systems can now do native and more granular functions such as clone, replication, snapshot among others as opposed to simply working on a coarse LUN basis. The similar concepts extend over to NAS NFS based access. Granted, there are more to VVOL’s including ability to get the underlying storage system more closely integrated with the virtual machine, hypervisor and associated management including supported service manage and classes or categories of service across performance, availability, capacity, economics.

    What about VVOL, VAAI and VASA?

    VVOL’s are building from earlier VMware initiatives including VAAI and VASA. With VAAI, VMware hypervisor’s can off-load common functions to storage systems that support features such as copy, clone, zero copy among others like how a computer can off-load graphics processing to a graphics card if present.

    VASA however provides a means for visibility, insight and awareness between the hypervisor and its associated management (e.g. vCenter etc) as well as the storage system. This includes storage systems being able to communicate and publish to VMware its capabilities for storage space capacity, availability, performance and configuration among other things.

    With VVOL’s VASA gets leveraged for unidirectional (e.g. two-way) communication where VMware hypervisor and management tools can tell the storage system of things, configuration, activities to do among others. Hence why VASA is important to have in your VMware CASA.

    What’s this object storage stuff?

    VVOL’s are a form of object storage access in that they differ from traditional block (LUN’s) and files (NAS volumes/mount points). However, keep in mind that not all object storage are the same as there are object storage access and architectures.

    object storage
    Object Storage basics, generalities and block file relationships

    Avoid making the mistake of when you hear object storage that means ANSI T10 (the folks that manage the SCSI command specifications) Object Storage Device (OSD) or something else. There are many different types of underlying object storage architectures some with block and file as well as object access front ends. Likewise there are many different types of object access that sit on top of object architectures as well as traditional storage system.

    Object storage I/O
    An example of how some object storage gets accessed (not VMware specific)

    Also keep in mind that there are many different types of object access mechanism including HTTP Rest based, S3 (e.g. a common industry defacto standard based on Amazon Simple Storage Service), SNIA CDMI, SOAP, Torrent, XAM, JSON, XML, DICOM, IL7 just to name a few, not to mention various programmatic bindings or application specific implementations and API’s. Read more about object storage architectures, access and related topics, themes and trends at www.objecstoragecenter.com

    Server Storage I/O Network Benchmark Winter Olympic Games

    Storage I/O trends

    Server Storage I/O Network Benchmark Winter Olympic Games

    It is time for the 2014 Winter Olympic games in Sochi Russia where competitors including some athletes come together in what has become a mix of sporting and entertainment engaging activities.

    Games of inches and seconds, performance and skill

    Some of these activities including real Olympic game events are heavier on sports appeal, some with artistic and others pure entertainment with a mix of beauty, braun and maybe even a beast or two. Then there are those events that have been around since the last ice age, while others being post global warming era.

    Hence some have been around longer than others showing a mix of old, new in terms of the sports, athletes not to mention technology and their outfits.

    I mean how about some of the new snow boarding and things on skis being done, can you image if they brought in as a new "X" sport roller derby on the short speed skating track sponsored by Red Bull or Bud light? Wait, that sounds like the Red Bull Crashed Ice event (check this out if not familiar with) think motto cross, hockey, down hill on ice. How about getting some of the south African long distance sprinters to learn how to speed skate, talk about moving some gold metal as in medals back to the african continent! On the other hand, the current powers to be would lodge protest, change the benchmark or rules to stay in power, hmm, sound familiar with IT?

    Ok, enough of the fun stuff (for now), let’s get back on track here (catch that pun?).

    Metrics that matter, winners and losers

    Since these are the Olympics, lets also remember that there still awards for personal and team winners (along with second and third place), after all, if all Olympians were winners, there would be no losers and if no losers, how could there be a winner?

    Who or what decides the winners vs. losers involves metrics that matter, something that also applies to servers, storage I/O networking hardware, software and services.

    In the case of the Olympics, some of the sports or events are based on speed or how fast (e.g. time) something is done, or how much is accumulated or done in that amount of time while in other events the metrics that matter may be more of a mystery based on judging that maybe subjective.

    The technologies to record times, scores, movements and other things that go into scoring have certainly improved, as have the ability for fans to engage and vote their choice, or opposition via social media venues from twitter to face book among others.

    What about server storage I/O networking benchmarks

    There could easily be an Information Technology (IT) or data infrastructure benchmarking Olympics with events such as faster server (physical, virtual or cloud, personal or consortium team), storage, I/O and networking across hardware, software or services. Of course there would be different approaches favored by the various teams with disputes, protests and other things sometimes seen during Olympic games. One of the challenges however is what would be the metrics that matter particularly to the various marketing groups of each organization or their joint consortium?

    Just like with sports, which of the various industry trade groups or consortiums would be the ruling party or voice for a particular event specifying the competition criteria, scoring and other things. What happens when there is a break away group that launches their own competing approach yet when it comes time for the IT benchmarking Olympics, which of the various bodies does the Olympic committee defer to? In case you are not familiar with in sports there are various groups and sub-groups who can decide the participants for various supports perhaps independent of an overall group, sound like IT?

    Storage I/O trends

    Let the games begin

    So then the fun starts, however which of the events are relevant to your needs or interest, sure some are fun or entertaining while others are not practical. Some you can do yourself, while others are just fun to watch, both the thrill of victory and agony of defeat.

    This is similar to IT industry benchmarking and specmanship competitions, some of which is more relevant than others, then there are those that are entertaining.

    Likewise some benchmarks or workload claims can be reproduced to confirm the results or claims, while others remain more like the results of figure skating judges.

    Hence some of the benchmark games are more entertaining, however for those who are not aware or informed, they may turn out to be more misinformation or lead to poor decision-making.

    Consequently benchmarks and metrics that matter are those that most closely aging with what your environment is or will be doing.

    If your environment is going to be running a particularly simulation or script, than so be it, otoh, look for comparisons that are reflective.

    On the other hand, if you can’t find something that is applicable, then look at tools and results that have meaning along with relevance, not to mention that provide clarity and repeatable. Being repeatable means that you can get access to the tools, scripts or scenario (preferably free) to run in your own environment.

    There is a long list of benchmarks and workload simulation tools, as well as traces available, some for free, some for fee that apply to components, subsystems or complete application systems from server, storage I/O networking applications and hardware. These include those for Email such as Microsoft Exchange related, SQL databases, , LoginVSI for VDI, VMmark for VMware, Hadoop and HDFS related for big data among many others (see more here).

    Apples to Apples vs. Apple pie vs. Orange Jello

    Something else that matters are apples to apples vs. apples to oranges or worse, apple pie to orange Jello.

    This means knowing or gaining insight into the pieces as we as how they behave under different conditions as well as the entire system for a baseline (e.g normal) vs. abnormal.

    Hence its winter server storage I/O networking benchmark games with the first event having been earlier this week with team Brocade taking on Cisco. Here is a link to a post by Tony Bourke (@tbourke) that provides some interesting perspectives and interactions, along with a link here to the Brocade sponsored report done by Evaluator Group.

    In this match-up, Team Brocade (with HP servers, Brocade switches and an unnamed 16GFC SSD storage system) take on Team Cisco and their UCS (also an un-named 16GFC SSD system that I wonder if Cisco even knows whose’s it was?). Ironic that it was almost six years to the date that there was a similar winter benchmark wonder event when NetApp submitted an SPC result for EMC (read more about that cold day here).

    The Brocade FC (using HP servers and somebody’s SSD storage) vs. Cisco FCoE using UCS (and somebody else’s storage) comparison is actually quite entertaining, granted it can also be educational on what to do or not do, focus on or include among others things. The report also raises many questions that seem more wondering why somebody won in an ice figuring skating event vs. the winner of a men’s or women’s hockey game.

    Closing thoughts (for now)

    So here’s my last point and perspective, let’s have a side of context with them IOPs, TPS, bandwidth and other metrics that matter.

    Take metrics and benchmarks with a grain of salt however look for transparency in both how they are produced, information provided and most important, does it matter or is it relevant to your environment or simply entertaining.

    Lets see what the next event in the ongoing server storage I/O networking benchmark 2014 winter Olympic games will be.

    You can also take part in the on-going or re-emerging FC vs. FCoE hype and fud events by casting your vote here and see results below.

    Note the following poll is from a previous StorageIOblog post (Where has the FCoE hype and FUD gone? (with poll)).

    Disclosure: I used to work for Evaluator Group after working for a company called Inrange that competed with, then got absorbed (via CNT and McData) into Brocade who has been a client as has Cisco. I also do performance and functionality testing, audits, validation and proof of concepts services in my own as well as in client labs using various industry standard available tools and techniques. Otoh, not sure that I even need to disclose anything however its easy enough to do so why not ;).

    Storage I/O trends

    Fall 2013 StorageIO Update Newsletter

    Welcome to the Fall 2013 (joint September and October) edition of the StorageIO Update (newsletter) containing trends perspectives on cloud, virtualization and data infrastructure topics. It is fall (at least here in north America) which means conferences, symposium, virtual and physical events, seminars, webinars in addition to normal client project activities. Starting with VMworld back in late August, that event occurred in San Francisco which kicked off the fall (or back to school) season of activity. VMworld was followed with many other events including in-person along with virtual or on-line such as webinars, Google+ hangouts among others, not to mention all the briefings for vendor product announcements and updates. Check out the industry trends perspectives articles, comments and blog posts below that covers some activity over the past few months.

    VMworld 2013
    Congratulations to VMworld on the 10th anniversary of the event. With the largest installment yet of a VMworld in terms of attendance, there were also many announcements. Here are a synopsis of some of those announcements which of course included plenty of software defined marketing (SDM).

    CMG and Storage Performance
    During mid-September I was invited to give an industry trends and perspectives presentation to the Storage Performance Council (SPC) board. The SPC board were meeting in the Minneapolis area and I gave a brief talk about Metrics that Matter and importance of context with focus on applications. Speaking of the Minneapolis area, Tom Becchetti (@tbecchetti) organized a great CMG event hosted over at Blue Cross Blue Shield of Minnesota. I gave a discussion around Technolutionary, technology evolution and revolution, using old and new things in new ways.

    Check out our backup, restore, BC, DR and archiving (Under the resources section on StorageIO.com) for various presentation, book chapter downloads and other content.

    SNW Fall 2013 Long Beach
    Talking about traveling, there was a quick trip out to Long Beach for the fall 2013 edition of Storage Networking World (SNW) where I had some good meetings and conversations with those who were actually there. No need to sugar coat it, likewise no need to kick sand in its face. Plain and simple, SNW is not the event it used to be has been a common discussion theme for several years which I had set my expectation accordingly.

    Some have asked me why I even spent time, money and resources to attend SNW?

    My answer is that I had some meetings to attend to, wanted to see and meet with others who were going to be there, and perhaps even say goodbye to an event that I have been involved with for over a decade.

    Does that mean I’m all done with SNW?

    Not sure yet as will have to wait and see what SNIA and IDG/Computerworld the event co-owners and producers put together for future events. However there are enough other events and activities to pick up the slack which is part of what has caused the steady decline in events like SNW among others.

    Perhaps it is time for SNIA to partner with another adjacent yet like-minded organization such as CMG to collaborate and try doing something like what was done in the early 2000s? That is SNIA providing their own seminars along with others such as myself who involved with both CMG, SNW and SNIA to beef up or set up a storage and I/O focused track at the CMG event.

    Beyond those items mentioned above, or in the following section, there are plenty of interesting and exciting things occurring in the background that I cant talk about yet. However watch for future posts, commentary, perspectives and other information down the road (and in the not so distant future).

    Enjoy this edition of the StorageIO Update newsletter.

    Brouwer Storage Consultancy

    StorageIO in Europe (Netherlands)
    Spent over a week in the Netherlands where I presented three different seminar workshop sessions organized by Brouwer Storage Consultancy who is celebrating their 10th anniversary in business. These sessions spanned five full days of interactive discussions with an engaged diverse group of attendees in the Nijkerk area who came from across Holland to take part in these workshops.

    Congratulations to Gert and Frank Brouwer on their ten years of being in business and best wishes for many more. Fwiw those who are curious StorageIO will be ten years young in business in about two years.

    StorageIO Industry Trends and Perspectives

    Some observations from while in Europe:

    Continued cloud privacy concerns amplified by NSA and suspicion of US-based companies, yet many are not aware of similar concerns of European or UK-based firms from those outside those areas. While there were some cloud concern conversations over the demise of Nirvanix, those seemed less so then in the media or US given that at least in Holland they have seen other cloud and storage as a service firms come and go already. It should be noted that the US has also seen cloud and storage as a service startups come and go, however I think sometimes we or at least the media tends to have a short if not selective memory at times.

    In one of our workshops sessions we were talking about service level objectives (SLO), service level agreements (SLA), recovery point objectives (RPO) and recovery time objectives (RTO) among other themes. Somebody mentioned why the focus of time in RPO and questions why not a transactional perspective which I thought was a brilliant question. We had a good conversation in the group and concurred that while RPO is what the industry uses, that there also needs to be a transactional state context tie to what is inferred or assumed with RPO and RTO. Thus the importance of looking beyond just the point in time, however the importance of a transactional context or state, such as not just the time, however to a given transactional point.

    Note that transactional could mean database, file system, backup or data protection index or catalog, meta data repository or other entity. This is where some should be jumping up and down like Donkey in Shrek wanting to point out that is exactly what RTO and RPO refer to which would be great. However all to often what is assumed is not conveyed, thus those who don’t know, well, they assume or simply don’t know what others.

    StorageIO Industry Trends and Perspectives

    Data Dynamics StorageX 7.0 Intelligent Policy Based File Data Migration – There is no such thing as a data or information recession . Likewise, people and data are living longer as well as getting larger. These span various use cases from traditional to personal or at work productivity. From little to big data content, collaboration including file or document sharing to rich media applications all of which are leveraging unstructured data. For example, email, word processing back-office documents, web and text files, presentations (e.g. PowerPoint), photos, audio and video among others. These macro trends result in the continued growth of unstructured Network Attached Storage (NAS) file data.

    Thus, a common theme is adding management including automated data movement and migration to carry out structure around unstructured NAS file data. More than a data mover or storage migration tool, Data Dynamics StorageX is a software platform for adding storage management structure around unstructured local and distributed NAS file data. This includes heterogeneous vendor support across different storage system, protocols and tools including Windows CIFS and Unix/Linux NFS.

    Seagate Kinetic Cloud and Object Storage I/O platform (and Ethernet HDD)

    Storage I/O trends

    Seagate Kinetic Cloud and Object Storage I/O platform

    Seagate announced today their Kinetic platform and drive designed for use by object API accessed storage including for cloud deployments. The Kinetic platform includes Hard Disk Drives (HDD) that feature 1Gb Ethernet (1 GbE) attached devices that speak object access API or what Seagate refers to as a key / value.

    Seagate Kinetic architecture

    What is being announced with Seagate Kinetic Cloud and Object (Ethernet HDD) Storage?

    • Kinetic Open Storage Platform – Ethernet drives, key / value (object access) API, partner software
    • Software developer’s kits (SDK) – Developer tools, documentation, drive simulator, code libraries, code samples including for SwiftStack and Riak.
    • Partner ecosystem

    What is Kinetic?

    While it has 1 GbE ports, do not expect to be able to use those for iSCSI or NAS including NFS, CIFS or other standard access methods. Being Ethernet based, the Kinetic drive only supports the key value object access API. What this means is that applications, cloud or object stacks, key value and NoSQL data repositories, or other software that adopt the API can communicate directly using object access.

    Seagate Kinetic storage

    Internal, the HDD functions as a normal drive would store and accessing data, the object access function and translation layer shifts from being in an Object Storage Device (OSD) server node to inside the HDD. The Kinetic drive takes on the key value API personality over 1 GbE ports instead of traditional Logical Block Addressing (LBA) and Logical Block Number (LBN) access using 3g, 6g or emerging 12g SAS or SATA interfaces. Instead Kinetic drives respond to object access (aka what Seagate calls key / value) API commands such as Get, Put among others. Learn more about object storage, access and clouds at www.objectstoragecenter.com.

    Storage I/O trends

    Some questions and comments

    Is this the same as what was attempted almost a decade ago now with the T10 OSD drives?

    Seagate claims no.

    What is different this time around with Seagate doing a drive that to some may vaguely resemble the predecessor failed T10 OSD approach?

    Industry support for object access and API development have progressed from an era of build it and they will come thinking, to now where the drives are adapted to support current cloud, object and key value software deployment.

    Wont 1GbE ports be too slow vs. 12g or 6g or even 3g SAS and SATA ports?

    Keep in mind those would be apples to oranges comparisons based on the protocols and types of activity being handled. Kinetic types of devices initially will be used for large data intensive applications where emphasis is on storing or retrieving large amounts of information, vs. low latency transactional. Also, keep in mind that one of the design premises is to keep cost low, spread the work over many nodes, devices to meet those goals while relying on server-side caching tools.

    Storage I/O trends

    Does this mean that the HDD is actually software defined?

    Seagate or other HDD manufactures have not yet noticed the software defined marketing (SDM) bandwagon. They could join the software defined fun (SDF) and talk about a software defined disk (SDD) or software defined HDD (SDHDD) however let us leave that alone for now.

    The reality is that there is far more software that exists in a typical HDD than what is realized. Sure some of that is packaged inside ASICs (Application Specific Integrated Circuits) or running as firmware that can be updated. However, there is a lot of software running in a HDD hence the need for power yet energy-efficient processors found in those devices. On a drive per drive basis, you may see a Kinetic device consume more energy vs. other equivalence HDDs due to the increase in processing (compute) needed to run the extra software. However that also represents an off-load of some work from servers enabling them to be smaller or do more work.

    Are these drives for everybody?

    It depends on if your application, environment, platform and technology can leverage them or not. This means if you view the world only through what is new or emerging then these drives may be for all of those environments, while other environments will continue to leverage different drive options.

    Object storage access

    Does this mean that block storage access is now dead?

    Not quite, after all there is still some block activity involved, it is just that they have been further abstracted. On the other hand, many applications, systems or environments still rely on block as well as file based access.

    What about OpenStack, Ceph, Cassandra, Mongo, Hbase and other support?

    Seagate has indicated those and others are targeted to be included in the ecosystem.

    Seagate needs to be careful balancing their story and message with Kinetic to play to and support those focused on the new and emerging, while also addressing their bread and butter legacy markets. The balancing act is communicating options, flexibility to choose and adopt the right technology for the task without being scared of the future, or clinging to the past, not to mention throwing the baby out with the bath water in exchange for something new.

    For those looking to do object storage systems, or cloud and other scale based solutions, Kinetic represents a new tool to do your due diligence and learn more about.

    Part II: IBM Server Side Storage I/O SSD Flash Cache Software

    Storage I/O trends

    Part II IBM Server Flash Cache Storage I/O accelerator for SSD

    This is the second in a two-part post series on IBM’s Flash Cache Storage Accelerator (FCSA) for Solid State Device (SSD) storage announced today. You can view part I of the IBM FCSA announcement synopsis here.

    Some FCSA ssd cache questions and perspectives

    What is FCSA?
    FCSA is a server-side storage I/O or IOP caching software tool that makes use of local (server-side) nand flash SSD (PCIe cards or drives). As a cache tool (view IBM flash site here) FCSA provides persistent read caching on IBM servers (xSeries, Flex and Blade x86 based systems) with write through cache (e.g. data cached for later reads) while write data is written directly to block attached storage including SANs. back-end storage can be iSCSI, SAS, FC or FCoE based block systems from IBM or others including all SSD, hybrid SSD or traditional HDD based solutions from IBM and others.

    How is this different from just using a dedicated PCIe nand flash SSD card?
    FCSA complements those by using them as a persistent storage to cache storage I/O reads to boost performance. By using the PCIe nand flash card or SSD drives, FCSA and other storage I/O cache optimization tools free up valuable server-side DRAM from having to be used as a read cache on the servers. On the other hand, caching tools such as FCSA also keep local cached reads closer to the applications on the servers (e.g. locality of reference) reducing the impact on backed shared block storage systems.

    What is FCSA for?
    With storage I/O or IOPS and application performance in general, location matters due to locality of reference hence the need for using different approaches for various environments. IBM FCSA is a storage I/O caching software technology that reduces the impact of applications having to do random read operations. In addition to caching reads, FCSA also has a write-through cache, which means that while data written to back-end block storage including on iSCSI, SAS, FC or FCoE based storage (IBM or other vendors), a copy of the data is cached for later reads. Thus while the best storage I/O is the one that does not have to be done (e.g. can be resolved from cache), the second best would be writes that go to a storage system that are not competing with read requests (handled via cache).

    Storage I/O trends

    Who else is doing this?
    This is similar to what EMC initially announced and released in February 2012 with VFcache now renamed to be XtremSW along with other caching and IO optimization software from others (e.g. SANdisk, Proximal and Pernix among others.

    Does this replace IBM EasyTier?
    Simple answer is no, one is for tiering (e.g. EasyTier), the other is for IO caching and optimization (e.g. FCSA).

    Does this replace or compete with other IBM SSD technologies?
    With anything, it is possible to find a way to make or view it as competitive. However in general FCSA complements other IBM storage I/O optimization and management software tools such as EasyTier as well as leverage and coexist with their various SSD products (from PCIe cards to drives to drive shelves to all SSD and hybrid SSD solutions).

    How does FCSA work?
    The FCSA software works in either a physical machine (PM) bare metal mode with Microsoft Windows operating systems (OS) such as Server 2008, 2012 among others. There is also *nix support for RedHat Linux, along with in a VMware virtual machine (VM) environment. In a VMware environment High Availability (HA), DRS and VMotion services and capabilities are supported. Hopefully it will be sooner vs. later that we hear IBM do a follow-up announcement (pure speculation and wishful thinking) on more hypervisors (e.g. Hyper-V, Xen, KVM) support along with Centos, Ubuntu or Power based systems including IBM pSeries. Read more about IBM Pure and Flex systems here.

    What about server CPU and DRAM overhead?
    As should be expected, a minimal amount of server DRAM (e.g. main memory) and CPU processing cycles are used to support the FCSA software and its drivers. Note the reason I say as should be expected is how you can have software running on a server doing any type of work that does not need some amount of DRAM and processing cycles. Granted some vendors will try to spin and say that there is no server-side DRAM or CPU consumed which would be true if they are completely external to the server (VM or PM). The important thing is to understand how much of an impact in terms of CPU along with DRAM consumed along with their corresponding effectiveness benefit that are derived.

    Storage I/O trends

    Does FCSA work with NAS (NFS or CIFS) back-end storage?
    No this is a server-side block only cache solution. However having said that, if your applications or server are presenting shared storage to others (e.g. out the front-end) as NAS (NFS, CIFS, HDFS) using block storage (back-end), then FCSA can cache the storage I/O going to those back-end block devices.

    Is this an appliance?
    Short and simple answer is no, however I would not be surprised to hear some creative software defined marketer try to spin it as a flash cache software appliance. What this means is that FCSA is simply IO and storage optimization software for caching to boost read performance for VM and PM servers.

    What is this hardware or storage agnostic stuff mean?
    Simple, it means that FCSA can work with various nand flash PCIe cards or flash SSD drives installed in servers, as well as with various back-end block storage including SAN from IBM or others. This includes being able to use block storage using iSCSI, SAS, FC or FCoE attached storage.

    What is the difference between Easytier and FCSA?
    Simple, FCSA is providing read acceleration via caching which in turn should offload some reads from affecting storage systems so that they can focus on handling writes or read ahead operations. Easytier on the other hand is for as its name implies tiering or movement of data in a more deterministic fashion.

    How do you get FCSA?
    It is software that you buy from IBM that runs on an IBM x86 based server. It is licensed on a per server basis including one-year service and support. IBM has also indicated that they have volume or multiple servers based licensing options.

    Storage I/O trends

    Does this mean IBM is competing with other software based IO optimization and cache tool vendors?
    IBM is focusing on selling and adding value to their server solutions. Thus while you can buy the software from IBM for their servers (e.g. no bundling required), you cannot buy the software to run on your AMD/Seamicro, Cisco (including EMC/VCE and NetApp) , Dell, Fujitsu, HDS, HP, Lenovo, Oracle, SuperMicro among other vendors servers.

    Will this work on non-IBM servers?
    IBM is only supporting FCSA on IBM x86 based servers; however, you can buy the software without having to buy a solution bundle (e.g. servers or storage).

    What is this Cooperative Caching stuff?
    Cooperative caching takes the next step from simple read cache with write-through to also support chance coherency in a shared environment, as well as leverage tighter application or guest operating system and storage system integration. For example, applications can work with storage systems to make intelligent predictive informed decisions on what to pre-fetch or read ahead and cached, as well as enable cache warming on restart. Another example is where in a shared storage environment if one server makes a change to a shared LUN or volume that the local server-side caches are also updated to prevent stale or inconsistent reads from occurring.

    Can FCSA use multiple nand flash SSD devices on the same server?
    Yes, IBM FCSA supports use of multiple server-side PCIe and or drive based SSD devices.

    How is cache coherency maintained including during a reboot?
    While data stored in the nand flash SSD device is persistent, it’s up to the server and applications working with the storage systems to decide if there is coherent or stale data that needs to be refreshed. Likewise, since FCSA is server-side and back-end storage system or SAN agnostic, without cooperative caching it will not know if the underlying data for a storage volume changed without being notified from another server that modified it. Thus if using shared back-end including SAN storage, do your due diligence to make sure multi-host access to the same LUN’s or volumes is being coordinated with some server-side software to support cache coherency, something that would apply to all vendors.

    Storage I/O trends

    What about cache warming or reloading of the read cache?
    Some vendors who have tightly interested caching software and storage systems, something IBM refers to as cooperative caching that can have the ability to re-warm the cache. With solutions that support cache re-warming, the cache software and storage systems work together to main cache coherency while pre-loading data from the underlying storage system based on hot bands or other profiles and experience. As of this announcement, FCSA does not support cache warming on its own.

    Does IBM have service or tools to complement FCSA?
    Yes, IBM has an assessment, profile and planning tool that are available on a free consultation services basis with a technician to check your environment. Of course, the next logical step would be for IBM to make the tool available via free download or on some other basis as well.

    Do I recommend and have I tried FCSA?
    On paper, or WebEx, YouTube or other venue FCSA looks interesting and capable, a good fit for some environments particular if IBM server-based. However since my PM and VMware VM based servers are from other vendors, along with the fact that FCSA only runs on IBM servers, have not actually given it a hands on test drive yet. Thus if you are looking at storage I/O optimization and caching software tools for your VM or PM environment, checkout IBM FCSA to see if it meets your needs.

    General comments

    It is great to see server and storage systems vendors add value to their solutions with I/O and performance optimization as well as caching software tools. However, I am also concerned with the growing numbers of different software tools that only work with one vendor’s servers or storage systems, or at least are supported as such.

    This reminds me of a time not all that long ago (ok, for some longer than others) when we had a proliferation of different host bus adapter (HBA) driver and pathing drivers from various vendors. The result is a hodge podge (a technical term) of software running on different operating systems, hypervisors, PM’s, VMs, and storage systems, all of which need to be managed. On the other hand, for the time being perhaps the benefit will outweigh the pain of having different tools. That is where there are options from server-side vendor centric, storage system focused, or third-party software tool providers.

    Another consideration is that some tools work in VMware environments; others support multiple hypervisors while others also support bare metal servers or PMs. Which applies to your environment will of course depend. After all, if you are an all VMware environment given that many of the caching tools tend to be VMware focused, that gives more options vs. for those who are still predominately PM environments.

    Server and Storage IO Memory: DRAM and nand flash

    Storage I/O trends

    DRAM, DIMM, DDR3, nand flash memory, SSD, stating what’s often assumed

    Often what’s assumed is not always the case. For example in along with around server, storage and IO networking circles including virtual as well as cloud environments terms such as nand (Negated AND or NOT And) flash memory aka (Solid State Device or SSD), DRAM (Dynamic Random Access Memory), DDR3 (Double Data Rate 3) not to mention DIMM (Dual Inline Memory Module) get tossed around with the assumption everybody must know what they mean.

    On the other hand, I find plenty of people who are not sure what those among other terms or things are, sometimes they are even embarrassed to ask, particular if they are a self-proclaimed expert.

    So for those who need a refresh or primer, here you go, an excerpt from Chapter 7 (Servers – Physical, Virtual and Software) from my book "The Green and Virtual Data Center" (CRC Press) available at Amazon.com and other global venues in print and ebook formats.

    7.2.2 Memory

    Computers rely on some form of memory ranging from internal registers, local on-board processor Level 1 (L1) and Level 2 (L2) caches, random accessible memory (RAM), non-volatile RAM (NVRAM) or nand Flash (SSD) along with external disk storage. Memory, which includes external disk storage, is used for storing operating system software along with associated tools or utilities, application programs and data. Main memory or RAM, also known as dynamic RAM (DRAM) chips, is packaged in different ways with a common form being dual inline memory modules (DIMMs) for notebook or laptop, desktop PC and servers.

    RAM main memory on a server is the fastest form of memory, second only to internal processor or chip based registers, L1, L2 or local memory. RAM and processor based memories are volatile and non-persistent in that when power is removed, the contents of memory are lost. As a result, some form of persistent memory is needed to keep programs and data when power is removed. Read only memory (ROM) and NVRAM are both persistent forms of memory in that their contents are not lost when power is removed. The amount of RAM that can be installed into a server will vary with specific architecture implementation and operating software being used. In addition to memory capacity and packaging format, the speed of memory is also important to be able to move data and programs quickly to avoid internal bottlenecks. Memory bandwidth performance increases with the width of the memory bus in bits and frequency in MHz. For example, moving 8 bytes on a 64 bit buss in parallel at the same time at 100MHz provides a theoretical 800MByte/sec speed.

    To improve availability and increase the level of persistence, some servers include battery backed up RAM or cache to protect data in the event of a power loss. Another technique to protect memory data on some servers is memory mirroring where twice the amount of memory is installed and divided into two groups. Each group of memory has a copy of data being stored so that in the event of a memory failure beyond those correctable with standard parity and error correction code (ECC) no data is lost. In addition to being fast, RAM based memories are also more expensive and used in smaller quantities compared to external persistent memories such as magnetic hard disk drives, magnetic tape or optical based memory medias.

    Memory diagram
    Memory and Storage Pyramid

    The above shows a tiered memory model that may look familiar as the bottom part is often expanded to show tiered storage. At the top of the memory pyramid is high-speed processor memory followed by RAM, ROM, NVRAM and FLASH along with many forms of external memory commonly called storage. More detail about tiered storage is covered in chapter 8 (Data Storage – Data Storage – Disk, Tape, Optical, and Memory). In addition to being slower and lower cost than RAM based memories, disk storage along with NVRAM and FLASH based memory devices are also persistent.

    By being persistent, when power is removed, data is retained on the storage or memory device. Also shown in the above figure is that on a relative basis, less energy is used for power storage or memory at the bottom of the pyramid than for upper levels where performance increases. From a PCFE (Power, Cooling, Floor space, Economic) perspective, balancing memory and storage performance, availability, capacity and energy to a given function, quality of service and service level objective for a given cost needs to be kept in perspective and not considering simply the lowest cost for the most amount of memory or storage. In addition to gauging memory on capacity, other metrics include percent used, operating system page faults and page read/write operations along with memory swap activity as well memory errors.

    Base 2 versus base 10 numbering systems can account for some storage capacity that appears to “missing” when real storage is compared to what is expected to be seen. Disk drive manufacturers use base 10 (decimal) to count bytes of data while memory chip, server and operating system vendors typically use base 2 (binary) to count bytes of data. This has led to confusion when comparing a disk drive base 10 GB with a chip memory base 2 GB of memory capacity, such as 1,000,000,000 (10^9) bytes versus 1,073,741,824 (2^30) bytes. Nomenclature based on the International System of Units uses MiB, GiB and TiB to denote million, billion and trillion bytes for base 2 numbering with base 10 using MB, TB and GB . Most vendors do document how many bytes, sometimes in both base 2 and base 10, as well as the number of 512 byte sectors supported on their storage devices and storage systems, though it might be in the small print.

    How much storage performance do you want vs. need?

    Storage I/O trends

    How much storage I/O performance do you want vs. need?

    The answer to how much storage I/O performance you need vs. want probably depends on cost, for which applications along with benefit among other things.

    Storage I/O performance
    View Part II: How many IOPS can a HDD, HHDD or SSD do with VMware?

    I did a piece over at 21cit titled Parsing the Need for Speed in Storage that looks at those and other related themes including metrics that matter across tiered storage.

    Here is an excerpt:

    Can storage speed be too fast? Or, put another away, how do you decide a return on investments or innovation from the financial resources you spend on storage and the various technologies that go into storage performance.

    Think about it: Fast storage needs fast servers, IO and networking interfaces, software, firmware, hypervisors, operating systems, drivers, and a file system or database, along with applications. Then there are the other buzzword bingo technologies that are also factors, among them fast storage DRAM and flash Solid State Devices (SSD).

    Some questions to ask about storage I/O performance include among others:

    • How do response time, latency, and think or wait-times effect your environment and applications?
    • Do you know the location of your storage or data center performance bottlenecks?
    • If you remove bottlenecks in storage systems or appliances as well as in the data path, how will your application or the CPU in the server it runs on behave?
    • If your application server is currently showing high CPU due to the system overhead of having to wait for storage I/Os, you may see a positive improvement.
    • If more real work can be done now, will all of the components be ready to support each other without creating a new bottleneck?
    • Also speaking of storage I/O performance, how about can we get a side of context with them IOPs and other metrics that matter!

    So how about it, how much performance, for primary, secondary, backup, cloud or virtual storage do you want vs. need?

    Ok, nuff said for now.
