2010 and 2011 Trends, Perspectives and Predictions: More of the same?

2011 is not a typo, I figured that since Im getting caught up on some things, why not get a jump as well.

Since 2009 went by so fast, and that Im finally getting around to doing an obligatory 2010 predictions post, lets take a look at both 2010 and 2011.

Actually Im getting around to doing a post here having already done interviews and articles for others soon to be released.

Based on prior trends and looking at forecasts, a simple predictions is that some of the items for 2010 will apply for 2011 as well given some of this years items may have been predicted by some in 2008, 2007, 2006, 2005 or, well ok, you get the picture. :)

Predictions are fun and funny in that for some, they are taken very seriously, while for others, at best they are taken with a grain of salt depending on where you sit. This applies both for the reader as well as who is making the predictions along with various motives or incentives.

Some are serious, some not so much…

For some, predictions are a great way of touting or promoting favorite wares (hard, soft or services) or getting yet another plug (YAP is a TLA BTW) in to meet coverage or exposure quota.

Meanwhile for others, predictions are a chance to brush up on new terms for the upcoming season of buzzword bingo games (did you pick up on YAP).

In honor of the Vancouver winter games, Im expecting some cool Olympic sized buzzword bingo games with a new slippery fast one being federation. Some buzzwords will take a break in 2010 as well as 2011 having been worked pretty hard the past few years, while others that have been on break, will reappear well rested, rejuvenated, and ready for duty.

Lets also clarify something regarding predictions and this is that they can be from at least two different perspectives. One view is that from a trend of what will be talked about or discussed in the industry. The other is in terms of what will actually be bought, deployed and used.

What can be confusing is sometimes the two perspectives are intermixed or assumed to be one and the same and for 2010 I see that trend continuing. In other words, there is adoption in terms of customers asking and investigating technologies vs. deployment where they are buying, installing and using those technologies in primary situations.

It is safe to say that there is still no such thing as an information, data or processing recession. Ok, surprise surprise; my dogs could have probably made that prediction during a nap. However what this means is more data will need to be moved, processed and stored for longer periods of time and at a lower cost without degrading performance or availability.

This means, denser technologies that enable a lower per unit cost of service without negatively impacting performance, availability, capacity or energy efficiency will be needed. In other words, watch for an expanded virtualization discussion around life beyond consolidation for servers, storage, desktops and networks with a theme around productivity and virtualization for agility and management enablement.

Certainly there will be continued merger and acquisitions on both a small as well as large scale ranging from liquidation sales or bargain hunting, to large and a mega block buster or two. Im thinking in terms of outside of the box, the type that will have people wondering perhaps confused as to why such a deal would be done until the whole picture is reveled and thought out.

In other words, outside of perhaps IBM, HP, Oracle, Intel or Microsoft among a few others, no vendor is too large not to be acquired, merged with, or even involved in a reverse merger. Im also thinking in terms of vendors filling in niche areas as well as building out their larger portfolio and IT stacks for integrated solutions.

Ok, lets take a look at some easy ones, lay ups or slam dunks:

  • More cluster, cloud conversations and confusion (public vs. private, service vs. product vs. architecture)
  • More server, desktop, IO and storage consolidation (excuse me, server virtualization)
  • Data footprint impact reduction ranging from deletion to archive to compress to dedupe among others
  • SSD and in particular flash continues to evolve with more conversations around PCM
  • Growing awareness of social media as yet another tool for customer relations management (CRM)
  • Security, data loss/leap prevention, digital forensics, PCI (payment card industry) and compliance
  • Focus expands from gaming/digital surveillance /security and energy to healthcare
  • Fibre Channel over Ethernet (FCoE) mainstream in discussions with some initial deployments
  • Continued confusion of Green IT and carbon reduction vs. economic and productivity (Green Gap)
  • No such thing as an information, data or processing recession, granted budgets are strained
  • Server, Storage or Systems Resource Analysis (SRA) with event correlation
  • SRA tools that provide and enable automation along with situational awareness

The green gap of confusion will continue with carbon or environment centric stories and messages continue to second back stage while people realize the other dimension of green being productivity.

As previously mentioned, virtualization of servers and storage continues to be popular with an expanding focus from just consolidation to one around agility, flexibility and enabling production, high performance or for other systems that do not lend themselves to consolidation to be virtualized.

6GB SAS interfaces as well as more SAS disk drives continue to gain popularity. I have said in the past there was a long shot that 8GFC disk drives might appear. We might very well see those in higher end systems while SAS drives continue to pick up the high performance spinning disk role in mid range systems.

Granted some types of disk drives will give way over time to others, for example high performance 3.5” 15.5K Fibre Channel disks will give way to 2.5” 15.5K SAS boosting densities, energy efficiency while maintaining performance. SSD will help to offload hot spots as they have in the past enabling disks to be more effectively used in their applicable roles or tiers with a net result of enhanced optimization, productivity and economics all of which have environmental benefits (e.g. the other Green IT closing the Green Gap).

What I dont see occurring, or at least in 2010

  • An information or data recession requiring less server, storage, I/O networking or software resources
  • OSD (object based disk storage without a gateway) at least in the context of T10
  • Mainframes, magnetic tape, disk drives, PCs, or Windows going away (at least physically)
  • Cisco cracking top 3, no wait, top 5, no make that top 10 server vendor ranking
  • More respect for growing and diverse SOHO market space
  • iSCSI taking over for all I/O connectivity, however I do see iSCSI expand its footprint
  • FCoE and flash based SSD reaching tipping point in terms of actual customer deployments
  • Large increases in IT Budgets and subsequent wild spending rivaling the dot com era
  • Backup, security, data loss prevention (DLP), data availability or protection issues going away
  • Brett Favre and the Minnesota Vikings winning the super bowl

What will be predicted at end of 2010 for 2011 (some of these will be DejaVU)

  • Many items that were predicted this year, last year, the year before that and so on…
  • Dedupe moving into primary and online active storage, rekindling of dedupe debates
  • Demise of cloud in terms of hype and confusion being replaced by federation
  • Clustered, grid, bulk and other forms of scale out storage grow in adoption
  • Disk, Tape, RAID, Mainframe, Fibre Channel, PCs, Windows being declared dead (again)
  • 2011 will be the year of Holographic storage and T10 OSD (an annual prediction by some)
  • FCoE kicks into broad and mainstream deployment adoption reaching tipping point
  • 16Gb (16GFC) Fibre Channel gets more attention stirring FCoE vs. FC vs. iSCSI debates
  • 100GbE gets more attention along with 4G adoption in order to move more data
  • Demise of iSCSI at the hands of SAS at low end, FCoE at high end and NAS from all angles

Gaining ground in 2010 however not yet in full stride (at least from customer deployment)

  • On the connectivity front, iSCSI, 6Gb SAS, 8Gb Fibre Channel, FCoE and 100GbE
  • SSD/flash based storage everywhere, however continued expansion
  • Dedupe  everywhere including primary storage – its still far from its full potential
  • Public and private clouds along with pNFS as well as scale out or clustered storage
  • Policy based automated storage tiering and transparent data movement or migration
  • Microsoft HyperV and Oracle based server virtualization technologies
  • Open source based technologies along with heterogeneous encryption
  • Virtualization life beyond consolidation addressing agility, flexibility and ease of management
  • Desktop virtualization using Citrix, Microsoft and VMware along with Microsoft Windows 7

Buzzword bingo hot topics and themes (in no particular order) include:

  • 2009 and previous year carry over items including cloud, iSCSI, HyperV, Dedupe, open source
  • Federation takes over some of the work of cloud, virtualization, clusters and grids
  • E2E, End to End management preferably across different technologies
  • SAS, Serial Attached SCSI for server to storage systems and as disk to storage interface
  • SRA, E23, Event correlation and other situational awareness related IRM tools
  • Virtualization, Life beyond consolidation enabling agility, flexibility for desktop, server and storage
  • Green IT, Transitions from carbon focus to economic with efficiency enabling productivity
  • FCoE, Continues to evolve and mature with more deployments however still not at tipping point
  • SSD, Flash based mediums continue to evolve however tipping point is still over the horizon
  • IOV, I/O Virtualization for both virtual and non virtual servers
  • Other new or recycled buzzword bingo candidates include PCoIP, 4G,

RAID will again be pronounced as being dead no longer relevant yet being found in more diverse deployments from consumer to the enterprise. In other words, RAID may be boring and thus no longer relevant to talk about, yet it is being used everywhere and enhanced in evolutionary ways, perhaps for some even revolutionary.

Tape remains being declared dead (e.g. on the Zombie technology list) yet being enhanced, purchased and utilized at higher rates with more data stored than in past history. Instead of being killed off by the disk drive, tape is being kept around for both traditional uses as well as taking on new roles where it is best suited such as long term or bulk off-line storage of data in ultra dense and energy efficient not to mention economical manners.

What I am seeing and hearing is that customers using tape are able to reduce the number of drives or transports, yet due to leveraging disk buffers or caches including from VTL and dedupe devices, they are able to operate their devices at higher utilization, thus requiring fewer devices with more data stored on media than in the past.

Likewise, even though I have been a fan of SSD for about 20 years and am bullish on its continued adoption, I do not see SSD killing off the spinning disk drive anytime soon. Disk drives are helping tape take on this new role by being a buffer or cache in the form of VTLs, disk based backup and bulk storage enhanced with compression, dedupe, thin provision and replication among other functionality.

There you have it, my predictions, observations and perspectives for 2010 and 2011. It is a broad and diverse list however I also get asked about and see a lot of different technologies, techniques and trends tied to IT resources (servers, storage, I/O and networks, hardware, software and services).

Lets see how they play out.

Ok, nuff said.

RAID Relevance Revisited

Following up from some previous posts on the topic, a continued discussion point in the data storage industry is the relevance (or lack there) of RAID (Redundant Array of Independent Disks).

These discussions tend to evolve around how RAID is dead due to its lack of real or perceived ability to continue scaling in terms of performance, availability, capacity, economies or energy capabilities needed or when compared to those of newer techniques, technologies or products.

RAID Relevance

While there are many new and evolving approaches to protecting data in addition to maintaining availability or accessibility to information, RAID despite the fan fare is far from being dead at least on the technology front.

Sure, there are issues or challenges that require continued investing in RAID as has been the case over the past 20 years; however those will also be addressed on a go forward basis via continued innovation and evolution along with riding technology improvement curves.

Now from a marketing standpoint, ok, I can see where the RAID story is dead, boring, and something new and shiny is needed, or, at least change the pitch to sound like something new.

Consequently, when being long in the tooth and with some of the fore mentioned items among others, older technologies that may be boring or lack sizzle or marketing dollars can and often are declared dead on the buzzword bingo circuit. After all, how long now has the industry trade group RAID Advisory Board (RAB) been missing in action, retired, spun down, archived or ILMed?

RAID remains relevant because like other dead or zombie technologies it has reached the plateau of productivity and profitability. That success is also something that emerging technologies envy as their future domain and thus a classic marketing move is to declare the incumbent dead.

The reality is that RAID in all of its various instances from hardware to software, standard to non-standard with extensions is very much alive from the largest enterprise to the SMB to the SOHO down into consumer products and all points in between.

Now candidly, like any technology that is about 20 years old if not older after all, the disk drive is over 50 years old and been declared dead for how long now?.RAID in some ways is long in the tooth and there are certainly issues to be addressed as have been taken care of in the past. Some of these include the overhead of rebuilding large capacity 1TB, 2TB and even larger disk drives in the not so distant future.

There are also issues pertaining to distributed data protection in support of cloud, virtualized or other solutions that need to be addressed. In fact, go way way back to when RAID appeared commercially on the scene in the late 80s and one of the value propositions among others was to address the reliability of emerging large capacity multi MByte sized SCSI disk drives. It seems almost laughable today that when a decade later, when the 1GB disk drives appeared in the market back in the 90s that there was renewed concern about RAID and disk drive rebuild times.

Rest assured, I think that there is a need and plenty of room for continued innovate evolution around RAID related technologies and their associated storage systems or packaging on a go forward basis.

What I find interesting is that some of the issues facing RAID today are similar to those of a decade ago for example having to deal with large capacity disk drive rebuild, distributed data protecting and availability, performance, ease of use and so the list goes.

However what happened was that vendors continued to innovate both in terms of basic performance accelerated rebuild rates with improvements to rebuild algorithms, leveraged faster processors, busses and other techniques. In addition, vendors continued to innovate in terms of new functionality including adopting RAID 6 which for the better part of a decade outside of a few niche vendors languished as one of those future technologies that probably nobody would ever adopt, however we know that to be different now and for the past several years. RAID 6 is one of those areas where vendors who do not have it are either adding it, enhancing it, or telling you why you do not need it or why it is no good for you.

An example of how RAID 6 is being enhanced is boosting performance on normal read and write operations along with acceleration of performance during disk rebuild. Also tied to RAID 6 and disk drive rebuild are improvements in controller design to detect and proactively make repairs on the fly to minimize or eliminate errors or diminished the need for drive rebuilds, similar to what was done in previous generations. Lets also not forget the improvements in disk drives boosting performance, availability, capacity and energy improvements over time.

Funny how these and other enhancements are similar to those made to RAID controllers hardware and software fine tuning them in the early to mid 2000s in support for high capacity SATA disk drives that had different RAS characteristics of higher performance lower capacity enterprise drives.

Here is my point.

RAID to some may be dead while others continue to rely on it. Meanwhile others are working on enhancing technologies for future generations of storage systems and application requirements. Thus in different shapes, forms, configurations, feature; functionality or packaging, the spirit of RAID is very much alive and well remaining relevant.

Regardless of if a solution using two or three disk mirroring for availability, or RAID 0 fast SSD or SAS or FC disks in a stripe configuration for performance with data protection via rapid restoration from some other low cost medium (perhaps RAID 6 or tape), or perhaps single, dual or triple parity protection, or if using small block or multiMByte or volume based chunklets, let alone if it is hardware or software based, local or disturbed, standard or non standard, chances are there is some theme of RAID involved.

Granted, you do not have to call it RAID if you prefer!

As a closing thought, if RAID were no longer relevant, than why do the post RAID, next generation, life beyond RAID or whatever you prefer to call them technologies need to tie themselves to the themes of RAID? Simple, RAID is still relevant in some shape or form to different audiences as well as it is a great way of stimulating discussion or debate in a constantly evolving industry.

BTW, Im still waiting for the revolutionary piece of hardware that does not require software, and the software that does not require hardware and that includes playing games with server less servers using hypervisors :) .

Provide your perspective on RAID and its relevance in the following poll.

Here are some additional related and relevant RAID links of interests:

Stay tuned for more about RAIDs relevance as I dont think we have heard the last on this.

Ok, nuff said.

    Is MAID Storage Dead? I Dont Think So!

    Some vendors are doing better than others and first generation MAID (Massive or monolithic Array of Idle Disks) might be dead or about to be deceased, spun down or put into a long term sleep mode, it is safe to say that second generation MAID (e.g. MAID 2.0) also known as intelligent power management (IPM) is alive and doing well.

    In fact, IPM is not unique to disk storage or disk drives as it is also a technique found in current generation of processors such as those from Intel (e.g. Nehalem) and others.

    Other names for IPM include adaptive voltage scaling (AVS), adaptive voltage scaling optimized (AVSO) and adaptive power management (APM) among others.

    The basic concept is to vary the amount of power being used to the amount of work and service level needed at a point in time and on a granular basis.

    For example, first generation MAID or drive spin down as deployed by vendors such as Copan, which is rumored to be in the process of being spun down as a company (see blog post by a former Copan employee) were binary. That is, a disk drive was either on or off, and, that the granularity was the entire storage system. In the case of Copan, the granularly was that a maximum of 25% of the disks could ever be spun up at any point in time. As a point of reference, when I ask IT customers why they dont use MAID or IPM enabled technology they commonly site concerns about performance, or more importantly, the perception of bad performance.

    CPU chips have been taking the lead with the ability to vary the voltage and clock speed, enabling or disabling electronic circuitry to align with amount of work needing to be done at a point in time. This more granular approach allows the CPU to run at faster rates when needed, slower rates when possible to conserve energy (here, here and here).

    A common example is a laptop with technology such as speed step, or battery stretch saving modes. Disk drives have been following this approach by being able to vary their power usage by adjusting to different spin speeds along with enabling or disabling electronic circuitry.

    On a granular basis, second generation MAID with IPM enabled technology can be done on a LUN or volume group basis across different RAID levels and types of disk drives depending on specific vendor implementation. Some examples of vendors implementing various forms of IPM for second generation MAID to name a few include Adaptec, EMC, Fujitsu Eternus, HDS (AMS), HGST (disk drives), Nexsan and Xyratex among many others.

    Something else that is taking place in the industry seems to be vendors shying away from using the term MAID as there is some stigma associated with performance issues of some first generation products.

    This is not all that different than what took place about 15 years ago or so when the first purpose built monolithic RAID arrays appeared on the market. Products such as the SF2 aka South San Francisco Forklift company product called Failsafe (here and here) which was bought by MTI with patents later sold to EMC.

    Failsafe, or what many at DEC referred to as Fail Some was a large refrigerator sized device with 5.25” disk drives configured as RAID5 with dedicated hot spare disk drives. Thus its performance was ok for the time doing random reads, however writes in the pre write back cache RAID5 days was less than spectacular.

    Failsafe and other early RAID (and here) implementations received a black eye from some due to performance, availability and other issues until best practices and additional enhancements such as multiple RAID levels appeared along with cache in follow on products.

    What that trip down memory (or nightmare) lane has to do with MAID and particularly first generation products that did their part to help establish new technology is that they also gave way to second, third, fourth, fifth, sixth and beyond generations of RAID products.

    The same can be expected as we are seeing with more vendors jumping in on the second generation of MAID also known as drive spin down with more in the wings.

    Consequently, dont judge MAID based solely on the first generation products which could be thought of as advanced technology production proof of concept solutions that will have paved the way for follow up future solutions.

    Just like RAID has become so ubiquitous it has been declared dead making it another zombie technology (dead however still being developed, produced, bought and put to use), follow on IPM enabled generations of technology will be more transparent. That is, similar to finding multiple RAID levels in most storage, look for IPM features including variable drive speeds, power setting and performance options on a go forward basis. These newer solutions may not carry the MAID name, however the sprit and function of intelligent power management without performance compromise does live on.

    Ok, nuff said.

    EMC Storage and Management Software Getting FAST

    EMC has announced the availability of the first phase of FAST (Fully Automated Storage Tiering) functionality for their Symmetrix VMAX, CLARiiON and Celerra storage systems.

    FAST was first previewed earlier this year (see here and here).

    Key themes of FAST are to leverage policies for enabling automation to support large scale environments, doing more with what you have along with enabling virtual data centers for traditional, private and public clouds as well as enhancing IT economics.

    This means enabling performance and capacity planning analysis along with facilitating load balancing or other infrastructure optimization activities to boost productivity, efficiency and resource usage effectiveness not to mention enabling Green IT.

    Is FAST revolutionary? That will depend on who you talk or listen to.

    Some vendors will jump up and down similar to donkey in shrek wanting to be picked or noticed claiming to have been the first to implement LUN or file movement inside of storage systems, or, as operating system or file system or volume manager built in. Others will claim to have done it via third party information lifecycle management (ILM) software including hierarchal storage management (HSM) tools among others. Ok, fair enough, than let their games begin (or continue) and I will leave it up to the variou vendors and their followings to debate whos got what or not.

    BTW, anyone remember system manage storage on IBM mainframes or array based movement in HP AutoRAID among others?

    Vendors have also in the past provided built in or third party add on tools for providing insight and awareness ranging from capacity or space usage and allocation storage resource management (SRM) tools, performance advisory activity monitors or charge back among others. For example, hot files analysis and reporting tool have been popular in the past, often operating system specific for identifying candidate files for placement on SSD or other fast storage. Granted the tools provided insight and awareness, there was still the time and error prone task of decision making and subsequently data movement, not to mention associated down time.

    What is new here with FAST is the integrated approach, tools that are operating system independent, functionality in the array, available for different product family and price bands as well as that are optimized for improving user and IT productivity in medium to high-end enterprise scale environments.

    One of the knocks on previous technology is either the performance impact to an application when data was moved, or, impact to other applications when data is being moved in the background. Another issue has been avoiding excessive thrashing due to data being moved at the expense of taking performance cycles from production applications. This would also be similar to having too many snapshots or raid rebuild that are not optimized running in the background on a storage system lacking sufficient performance capability. Another knock has been that historically, either 3rd party host or appliance based software was needed, or, solutions were designed and targeted for workgroup, departmental or small environments.

    What is FAST and how is it implemented
    FAST is technology for moving data within storage systems (and external for Celerra) for load balancing, capacity and performance optimization to meet quality of service (QoS) performance, availability, capacity along with energy and economic initiatives (figure1) across different tiers or types of storage devices. For example, moving data from slower SATA disks where a performance bottleneck exists to faster Fibre Channel or SSD devices. Similarly, cold or infrequently data on faster more expensive storage devices can be marked as candidates for migration to lower cost SATA devices based on customer policies.

    EMC FAST
    Figure 1 FAST big picture Source EMC

    The premise is that policies are defined based on activity along with capacity to determine when data becomes a candidate for movement. All movement is performed in the background concurrently while applications are accessing data without disruptions. This means that there are no stub files or application pause or timeouts that occur or erratic I/O activity while data is being migrated. Another aspect of FAST data movement which is performed in the actual storage systems by their respective controllers is the ability for EMC management tools to identify hot or active LUNs or volumes (files in the case of Celerra) as candidates for moving (figure 2).

    EMC FAST
    Figure 2 FAST what it does Source EMC

    However, users specify if they want data moved on its own or under supervision enabling a deterministic environment where the storage system and associated management tools makes recommendations and suggestions for administrators to approve before migration occurs. This capacity can be a safeguard as well as a learn mode enabling organizations to become comfortable with the technology along with its recommendations while applying knowledge of current business dynamics (figure 3).

    EMC FAST
    Figure 3 The Value proposition of FAST Source EMC

    FAST is implemented as technology resident or embedded in the EMC VMAX (aka Symmetrix), CLARiiON and Cellera along with external management software tools. In the case of the block (figure 4) storage systems including DMX/VMAX and CLARiiON family of products that support FAST, data movement is on a LUN or volume basis and within a single storage system. For NAS or file based Cellera storage systems, FAST is implanted using FMA technology enabling either in the box or externally to other storage systems on a file basis.

    EMC FAST
    Figure 4 Example of FAST activity Source EMC

    What this means is that data at the LUN or volume level can be moved across different tiers of storage or disk drives within a CLARiiON instance, or, within a VMAX instance (e.g. amongst the nodes). For example, Virtual LUNs are a building block that is leveraged for data movement and migration combined with external management tools including Navisphere for the CLARiiON and Symmetrix management console along with Ionix all of which has been enhanced.

    Note however that initially data is not moved externally between different CLARiiONs or VMAX systems. For external data movement, other existing EMC tools would be deployed. In the case of Celerra, files can be moved within a specific CLARiiON as well as externally across other storage systems. External storage systems that files can be moved across using EMC FMA technology includes other Celleras, Centera and ATMOS solutions based upon defined policies.

    What do I like most and why?

    Integration of management tools providing insight with ability for user to setup polices as well as approve or intercede with data movement and placement as their specific philosophies dictate. This is key, for those who want to, let the system manage it self with your supervision of course. For those who prefer to take their time, then take simple steps by using the solution for initially providing insight into hot or cold spots and then helping to make decisions on what changes to make. Use the solution and adapt it to your specific environment and philosophy approach, what a concept, a tool that works for you, vs you working for it.

    What dont I like and why?

    There is and will remain some confusion about intra and inter box or system data movement and migration, operations that can be done by other EMC technology today for those who need it. For example I have had questions asking if FAST is nothing more than EMC Invista or some other data mover appliance sitting in front of Symmetrix or CLARiiONs and the answer is NO. Thus EMC will need to articulate that FAST is both an umbrella term as well as a product feature set combining the storage system along with associated management tools unique to each of the different storage systems. In addition, there will be confusion at least with GA of lack of support for Symmetrix DMX vs supported VMAX. Of course with EMC pricing is always a question so lets see how this plays out in the market with customer acceptance.

    What about the others?

    Certainly some will jump up and down claiming ratification of their visions welcoming EMC to the game while forgetting that there were others before them. However, it can also be said that EMC like others who have had LUN and volume movement or cloning capabilities for large scale solutions are taking the next step. Thus I would expect other vendors to continue movement in the same direction with their own unique spin and approach. For others who have in the past made automated tiering their marketing differentiation, I would suggest they come up with some new spins and stories as those functions are about to become table stakes or common feature functionality on a go forward basis.

    When and where to use?

    In theory, anyone with a Symmetrix/VMAX, CLARiiON or Celerra that supports the new functionality should be a candidate for the capabilities, that is, at least the insight, analysis, monitoring and situation awareness capabilities Note that does not mean actually enabling the automated movement initially.

    While the concept is to enable automated system managed storage (Hmmm, Mainframe DejaVu anyone), for those who want to walk before they run, enabling the insight and awareness capabilities can provide valuable information about how resources are being used. The next step would then to look at the recommendations of the tools, and if you concur with the recommendations, then take remedial action by telling the system when the movement can occur at your desired time.

    For those ready to run, then let it rip and take off as FAST as you want. In either situation, look at FAST for providing insight and situational awareness of hot and cold storage, where opportunities exist for optimizing and gaining efficiency in how resources are used, all important aspects for enabling a Green and Virtual Data Center not to mention as well as supporting public and private clouds.

    FYI, FTC Disclosure and FWIW

    I have done content related projects for EMC in the past (see here), they are not currently a client nor have they sponsored, underwritten, influenced, renumerated, utilize third party off shore swiss, cayman or south american unnumbered bank accounts, or provided any other reimbursement for this post, however I did personally sign and hand to Joe Tucci a copy of my book The Green and Virtual Data Center (CRC) ;).

    Bottom line

    Do I like what EMC is doing with FAST and this approach? Yes.

    Do I think there is room for improvement and additional enhancements? Absolutely!

    Whats my recommendation? Have a look, do your homework, due diligence and see if its applicable to your environment while asking others vendors what they will be doing (under NDA if needed).

    Ok, nuff said.

    SSD and Storage System Performance

    Jacob Gsoedl has a new article over at SearchStorage titled How to add solidstate storage to your enterprise data storage systems.

    In his article which includes some commentary by me, Jacob lays out various options on where and how to deploy solid state devices (SSD) in and with enterprise storage systems.

    While many vendors have jumped on the latest SSD bandwagon adding flash based devices to storage systems, where and how they implement the technologies varies.

    Some vendors take a simplistic approach of qualify flash SSD devices for attachment to their storage controllers similar to how any other Fibre Channel, SAS or SATA hard disk drive (HDD) would be.

    Yet others take a more in depth approach including optimizing controller software, firmware or micro code to leverage flash SSD devices along with addressing wear leveling, read and write performance among other capabilities.

    Performance is another area where on paper a flash SSD device might appear to be fast and enable a storage system to be faster.

    However, systems that are not optimized for higher throughput and or increased IOPs needing lower latency may end up placing restrictions on the number of flash SSD devices or other configuration constraints. Even worse is when expected performance improvements are not realized as after all, fast controllers need fast devices, and fast devices need fast controllers.

    RAM and flash based SSD are great enabling technologies for boosting performance, productivity and enabling a green efficient environment however do your homework.

    Look at how various vendors implement and support SSD particularly flash based products with enhancements to storage controllers for optimal performance.

    Likewise check out the activity of  the SNIA Solid State Storage Initiative (SSSI) among other industry trade group or vendor initiatives around enhancing along with best practices for SSD.

    The other Green Storage: Efficiency and Optimization

    Some believe that green storage is specifically designed to reduce power and cooling costs.

    The reality is that there are many ways to reduce environmental impact while enhancing the economics of data storage besides simply booting utilizing.

    These include optimizing data storage capacity as well as boosting performance to increase productivity per watt of energy used when work needs to be done.

    Some approaches require new hardware or software while others can be accomplished with changes to management including reconfiguration leveraging insight and awareness of resource needs.

    How to win approval for upgrades: Link them to business benefits

    Drew Rob has another good article over at Processor.com about various tips and strategies on how to gain approval for hardware (or software) purchases with some comments by yours truly.

    My tips and advice that are quoted in the story include to link technology resources to business needs impact which may be common sense, however still a time tested effective technique.

    Instead of speaking tech talk such as Performance, capacity, availability, IOPS, bandwidth, GHz, frames or packets per second, VMs to PM or dedupe ratio, map them to business speak, that is things that finance, accountants, MBAs or other management personal understand.

    For example, how many transactions at a given response time can be supported by a given type of server, storage or networking device.

    Or, put a different way, with a given device, how much work can be done and what is the associated monetary or business benefit.

    Likewise, if you do not have a capacity plan for servers, storage, I/O and networking along with software and facilities covering performance, availability, capacity and energy demands now is the time to put one in place.

    More on capacity and performance planning later, however for now, if you want to learn more, check Chapter 10 (Performance and Capacity Planning) in my book Resilient Storage Networks: Designing Flexible and Scalable Data Infrastructure: Elsevier).

    What is the Future of Servers?

    Recently I provided some comments and perspectives on the future of servers in an article over at Processor.com.

    In general, blade servers will become more ubiquitous, that is they wont go away even with cloud, rather become more common place with even higher density processors with more cores and performance along with faster I/O and larger memory capacity per given footprint.

    While the term blade server may fade giving way to some new term or phrase, rest assured their capabilities and functionality will not disappear, rather be further enhanced to support virtualization with VMware vsphere, Microsoft HyperV, Citrix/Zen along with public and private clouds, both for consolidation and in the next wave of virtualization called life beyond consolidation.

    The other trend is that not only will servers be able to support more processing and memory per footprint; they will also do that drawing less energy requiring lower cooling demands, hence more Ghz per watt along with energy savings modes when less work needs to be performed.

    Another trend is around convergence both in terms of packaging along with technology improvements from a server, I/O networking and storage perspective. For example, enhancements to shared PCIe with I/O virtualization, hypervisor optimization, and integration such as the recently announced EMC, Cisco, Intel and VMware VCE coalition and vblocks.

    Read more including my comments in the article here.

    Justifying Green IT and Home Hardware Upgrades with EnergyStar

    Energy Star

    Have you seen the TV commercials or print advertisements where an energy star washer is mentioned as so efficient that the savings from reduced power consumption are enough to pay for the dryer? If not, check out the EPA Energy Star website for information about various programs, savings and efficiency options to learn more

    What does this have to do with servers, storage, networking, data centers or other IT equipment?

    Simple, if you are not aware, Energy Star for Servers now exits and is being enhanced while good progress is being made on the Energy Star for storage program.

    The Energy Star for household appliances has been around a bit longer and more refined, something that I anticipated the server and storage programs to follow-suit with over time.

    What really caught my eye with the commercial is the focus on closing the green gap, that is instead of the green environmental impact savings of an appliance that uses less power and subsequent carbon footprint benefits, the message is to the economic hot button. That is, switch to more energy efficient technology that allows more work to done at a lower overall cost and the savings can help self fund the enhancements.

    For example, a more energy efficient server that can do more work or GHz per watt of energy when needed, or, to go into lower power modes (intelligent power management: IPM). Low power modes do not necessarily mean turning completely off, rather, drawing less energy and subsequently lower cooling demands during slow periods such as with new Intel Nehalem and other processors.

    From a disk storage perspective, energy efficiency is often thought to be avoidance or turning disk drives off boosting capacity and squeezing data footprints.

    However energy efficiency and savings can also be achieved by slowing a disk drive down or turning of some of the electronics to reduce energy consumption and heat generation.

    Other forms of energy savings include thin provisioning and deduplication however another form of energy efficiency for storage is boosting performance. That is, doing more work per watt of energy for active or time sensitive applications or usage scenarios.

    Thus there is another Green IT, one that provides both economic and environmental benefits!

    Acadia VCE: VMware + Cisco + EMC = Virtual Computing Environment

    Was today the day the music died? (click here or here if you are not familar with the expression)

    Add another three letter acronym (TLA) to your IT vocabulary if you are involved with server, storage, networking, virtualization, security and related infrastructure resource management (IRM) topics.

    That new TLA is Virtual Computing Environment (VCE), a coalition formed by EMC and Cisco along with partner Intel called Acadia that was announced today. Of course, EMC who also happens to own VMware for virtualization and RSA for security software tools bring those to the coalition (read press release here).

    For some quick fun, twittervile and the blogosphere have come up with other meanings such as:

    VCE = Virtualization Communications Endpoint
    VCE = VMware Cisco EMC
    VCE = Very Cash Efficient
    VCE = VMware Controls Everything
    VCE = Virtualization Causes Enthusiasm
    VCE = VMware Cisco Exclusive

    Ok, so much for some fun, at least for now.

    With Cisco, EMC and VMware announcing their new VCE coalition, has this signaled the end of servers, storage, networking, hardware and software for physical, virtual and clouding computing as we know it?

    Does this mean all other vendors not in this announcement should pack it up, game over and go home?

    The answer in my perspective is NO!

    No, the music did not end today!

    NO, servers, storage and networking for virtual or cloud environments has not ended.

    Also, NO, other vendors do not have to go home today, the game is not over!

    However a new game is on, one that some have seen before, for others it is something new, exciting perhaps revolutionary or an industry first.

    What was announced?
    Figure 1 shows a general vision or positioning from the three major players involved along with four tenants or topic areas of focus. Here is a link to a press release where you can read more.

    CiscoVirtualizationCoalition.png
    Figure 1: Source: Cisco, EMC, VMware

    General points include:

    • A new coalition (e.g. VCE) focused on virtual compute for cloud and non cloud environments
    • A new company Acadia owned by EMC and Cisco (1/3 each) along with Intel and VMware
    • A new go to market pre-sales, service and support cross technology domain skill set team
    • Solution bundles or vblocks with technology from Cisco, EMC, Intel and VMware

    What are the vblocks and components?
    Pre-configured (see this link for a 3D model), tested, and supported with a single throat to choke model for streamlined end to end management and acquisition. There are three vblocks or virtual building blocks that include server, storage, I/O networking, and virtualization hypervisor software along with associated IRM software tools.

    Cisco is bringing to the game their Unified Compute Solution (UCS) server along with Nexus 1000v and Multilayer Director (MDS) switches, EMC is bringing storage (Symmetrix VMax, CLARiiON and unified storage) along with their RSA security and Ionix IRM tools. VMware is providing their vSphere hypervisors running on Intel based services (via Cisco).

    The components include:

    • EMC Ionix management tools and framework – The IRM tools
    • EMC RSA security framework software – The security tools
    • EMC VMware vSphere hypervisor virtualization software – The virtualization layer
    • EMC VMax, CLARiiON and unified storage systems – The storage
    • Cisco Nexus 1000v and MDS switches – The Network and connectivity
    • Cisco Unified Compute Solution (UCS) – The physical servers
    • Services and support – Cross technology domain presales, delivery and professional services

    CiscoEMCVMwarevblock.jpg
    Figure 2: Source: Cisco vblock (Server, Storage, Networking and Virtualization Software) via Cisco

    The three vblock models are:
    Vblock0: entry level system due out in 2010 supporting 300 to 800 VMs for initial customer consolidation, private clouds or other diverse applications in small or medium sized business. You can think of this as a SAN in a CAN or Data Center in a box with Cisco UCS and Nexus 1000v, EMC unified storage secured by RSA and VMware vSphere.

    Vblock1: mid sized building block supporting 800 to 3000 VMs for consolidation and other optimization initiatives using Cisco UCS, Nexus and MDS switches along with EMC CLARiiON storage secured with RSA software hosting VMware hypervisors.

    Vblock2 high end supporting up 3000 to 6000 VMs for large scale data center transformation or new virtualization efforts combing Cisco Unified Computing System (UCS), Nexus 1000v and MDS switches and EMC VMax Symmetix storage with RSA security software hosting VMware vSpshere hypervisor.

    What does this all mean?
    With this move, for some it will add fuel to the campfire that Cisco is moving closer to EMC and or VMware with a pre-nuptial via Acadia. For others, this will be seen as fragmentation for virtualization particularly if other vendors such as Dell, Fujitsu, HP, IBM and Microsoft among others are kept out of the game, not to mention their channels of vars or IT customers barriers.

    Acadia is a new company or more precisely, a joint venture being created by major backers EMC and Cisco with minority backers being VMware and Intel.

    Like any other joint ventures, for examples those commonly seen in the airline industry (e.g. transportation utility) where carriers pool resources such as SkyTeam whose members include Delta who had a JV with Airframe owner of KLM who had a antitrust immunity JV with northwest (now being digested by Delta).

    These joint ventures can range from simple marketing alliances like you see with EMC programs such as their Select program to more formal OEM to ownership as is the case with VMware and RSA to this new model for Acadia.

    An airline analogy may not be the most appropriate, yet there are some interesting similarities, least of which that air carriers rely on information systems and technologies provided by members of this collation among others. There is also a correlation in that joint ventures are about streamlining and creating a seamless end to end customer experience. That is, give them enough choice and options, keep them happy, take out the complexities and hopefully some cost, and with customer control come revenue and margin or profits.

    Certainly there are opportunities to streamline and not just simply cut corners, perhaps that’s another area or analogy with the airlines where there is a current focus on cutting, nickel and dimming for services. Hopefully the Acadia and VCE are not just another example of vendors getting together around the campfire to sing Kumbaya in the name of increasing customer adoption, cost cutting or putting a marketing spin on how to sell more to customers for account control.

    Now with all due respect to the individual companies and personal, at least in this iteration, it is not as much about the technology or packaging. Likewise, while important, it is also not just about bundling, integration and testing (they are important) as we have seen similar solutions before.

    Rather, I think this has the potential for changing the way server, storage and networking hardware along with IRM and virtualization software are sold into organizations, for the better or worse.

    What Im watching is how Acadia and their principal backers can navigate the channel maze and ultimately the customer maze to sell a cross technology domain solution. For example, will a sales call require six to fourteen legs (e.g. one person is a two legged call for those not up on sales or vendor lingo) with a storage, server, networking, VMware, RSA, Ionix and services representative?

    Or, can a model to drive down the number of people or product specialist involved in a given sales call be achieved leveraging people with cross technology domain skills (e.g. someone who can speak server and storage hardware and software along with networking)?

    Assuming Acadia and VCE vblocks address product integration issues, I see the bigger issue as being streamlining the sales process (including compensation plans) along with how partners are dealt with not to mention customers.

    How will the sales pitch be to the Cisco network people at VARs or customer sites, or too the storage or server or VMware teams, or, all of the above?

    What about the others?
    Cisco has relationships with Dell, HP, IBM, Microsoft and Oracle/Sun among others that they will be stepping even more on the partner toes than when they launched the UCS earlier this year. EMC for its part if fairly diversified and is not as subservient to IBM however has a history of partnering with Dell, Oracle and Microsoft among others.

    VMware has a smaller investment and thus more in the wings as is Intel given that both have large partnership with Dell, HP, IBM and Microsoft. Microsoft is of interest here because on one front the bulk of all servers virtualized into VMware VMs are Windows based.

    On the other hand, Microsoft has their own virtualization hypervisor HyperV that depending upon how you look at it, could be a competitor of VMware or simply a nuisance. Im of the mindset that its still to early and don’t judge this game on the first round which VMware has won. Keep in mind the history such as desktop and browser wars that Microsoft lost in the first round only to come back strong later. This move could very well invigorate Microsoft, or perhaps Oracle, Citrix among others.

    Now this is far from the first time that we have seen alliances, coalitions, marketing or sales promotion cross technology vendor clubs in the industry let alone from the specific vendors involved in this announcement.

    One that comes to mind was 3COMs failed attempt in the late 90s to become the first traditional networking vendor to get into SANs, that was many years before Cisco could spell SAN let alone their Andiamo startup incubated. The 3COM initiative which was cancelled due to financial issues literally on the eve of rollout was to include the likes of STK (pre-sun), Qlogic, Anchor (People were still learning how to spell Brocade), Crossroads (FC to SCSI routers for tape), Legato (pre-EMC), DG CLARiiON (Pre-EMC), MTI (sold their patents to EMC, became a reseller, now defunct) along with some others slated to jump on the bandwagon.

    Lets also not forget that while among the traditional networking market vendors Cisco is the $32B giant and all of the others including 3Com, Brocade, Broadcom, Ciena, Emulex, Juniper and Qlogic are the seven plus dwarfs. However, keep the $23B USD Huawei networking vendor that is growing at a 45% annual rate in mind.

    I would keep an eye on AMD, Brocade, Citrix, Dell, Fujitsu, HP, Huawei, Juniper, Microsoft, NetApp, Oracle/Sun, Rackable and Symantec among many others for similar joint venture or marketing alliances.

    Some of these have already surfaced with Brocade and Oracle sharing hugs and chugs (another sales term referring to alliance meetings over beers or shots).

    Also keep in mind that VMware has a large software (customer business) footprint deployed on HP with Intel (and AMD) servers.

    Oh, and those VMware based VMs running on HP servers also just happen to be hosting in their neighbor of 80% or more Windows based guests operating systems, I would say its game on time.

    When I say its game on time, I dont think VMware is brash enough to cut HP (or others) off forcing them to move to Microsoft for virtualization. However the game is about control, control of technology stacks and partnerships, control of vars, integrators and the channel, as well as control of customers.

    If you cannot tell, I find this topic fun and interesting.

    For those who only know me from servers they often ask when did I learn about networking to which I say check out one of my books (Resilient Storage Networks-Elsevier). Meanwhile for others who know me from storage I get asked when did I learn about or get into servers to which I respond about 28 years ago when I worked in IT as the customer.

    Bottom line on Acadia, vblocks and VCE for now, I like the idea of a unified and bundled solution as long as they are open and flexible.

    On the other hand, I have many questions and even skeptical in some areas including of how this plays out for Cisco and EMC in terms of if it can be a unifier or polarized causing market fragmentation.

    For some this is or will be dejavu, back to the future, while for others it is a new, exciting and revolutionary approach while for others it will be new fodder for smack talk!

    More to follow soon.
