What do NAS NASA NASCAR have in common?

What do NAS NASA NASCAR have in common?

server storage I/O data infrastructure trends

Updated 2/10/2018

The other day it dawned on me what do NAS, NASA NASCAR have in common?

Several things in addition to all starting with the letters NAS it turns out.

For example, they all deal with round objects, NAS or Network Attached storage involved with circular spinning disk drives, NASA or National Aeronautical Space Administration besides involved with aircraft that have tires that go round and round, or airplanes circling waiting for landing.

In the case of NASA they are also involved with sending craft or devices to circle other planets or moons and land or crash into them. Sometimes NAS along with other storage systems have disk drives that crash, similar to how NASCAR events see accidents.

NASCAR is also involved with vehicles that dont or at least should not fly, however they do go round and round on a track, often paved however sometimes mud or dirt tracks plus high tech exists with computers and various data models, not to mention the NASCAR air force.

In addition to being involved with round objects and activities, all three are also involved in computing, generating, processing, storing and retrieving for analysis of data, not to mention high performance requirements.

NAS based storage can also be relied upon for serving the needs of NASA and NASCAR data and informational needs.

And FWIW, just for fun, look at what you get when you spell NAS, NASA or NASCAR backwards:

RACSAN

What This All Means

Not much actually other than to stimulate some thought, discussion as well as perhaps have some fun with technology during the holiday season.

Im sure if I put some more thought to it, more similarities would or will come to mind.

However, for now, thats it for a quick thought, what similarities do you see or know about with NAS, NASA and NASCAR?

Ok, nuf fun for now, time to work on some other posts, content and projects.

Ok, nuff said, for now.

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.

Ok, nuff said.

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.

Is IBM XIV still relevant?

That is a question I get asked quite a bit and based on discussions in other blogs and twitter tweets; it appears that Im not alone.

A little over a year ago I did a blog post about IBM and XIV, now seems like a good time to revisit, look back and look forward.

Is IBM XIV still relevant?

Given the time, money as well as effort IBM has poured into promoting and generating awareness around XIV, it must be relevant to someone.

IBM recently released another round of momentum news, customer testimonials and product enhancements while making a point that there are now over 1,000 XIV systems installed around the world. 1,000 systems installed (regardless of if revenue or trial) in the just under 2 years since IBM bought XIV would be a triumph for most startups.

However for a major player with the resources of IBM, I would have expected the number of installed systems to be more in the 5,000 to perhaps 10,000 systems when looking at the progress of Dell (EqualLogic), HP (LeftHand) or others.

Now granted, XIV is not IBMs only storage solution focus as there is the high-end DS8000 series, mid-range DS5000/DS4000/DS3000, NAS based N-Series, SVC for SAN virtualization, DR550 for archiving not to mention the TS series of virtual tape systems (VTS) and virtual tape libraries (VTLs) including the Diligent based technologies.

Ok, fair enough, good job for IBM in placing 1,000 XIV systems in just under two years.

Another trend I regularly see is that of an approach of if you are not on the XIV bandwagon, that is not in love with their message, then you are against it with no room in between.

However, are these successes at the expense of other IBM storage solutions being placed?

The reason I bring this up is in discussions, I regularly hear stories where XIVs competition is not only 3PAR, Dell, EMC, Fujitsu, HDS, HP, NetApp or Sun among others, its also IBMs other products, those with five or six digit installed bases being targeted.

Im continually amazed when I talk with XIV prospects along with vars who have either not been told about other IBM products, or, provided with apples to oranges comparison as well as even FUD against its own solutions.

Does this mean that Im against XIV?

Die hard XIV believers will say yes to which I will respond, ok fine if that is what you believe.

However to everyone else, I also say look before you leap as well as checkout alternatives from others include IBM, not to mention being careful of the possible hangover from drinking too much cool aid.

To everyone else, give XIV a look; however as with any solution, do your due diligence, ask tough questions along with talking to others.

As to the long term future of XIV, given all of the money and marketing effort that has been put into it, I don’t see it going away near-term. However, Im still on the fence as to its long term future and if it might join other IBM storage solutions in the holding pen such as the DS6000.

Would I recommend XIV to IT customers?

What I tell those that I talk to is due your homework regarding XIV, ask tough questions including asking about other or alternative IBM products, where they fit and their caveats as you would do with any other vendor.

I do believe that IBM storage in general is still very relevant.

I think that IBM has some great storage and data management solutions.

I think that IBM needs to take the blinders off or at least take the ropes off, remove the fences and let their teams and vars sell the whole solution set letting the customer decide perhaps in the course growing their storage business instead of helping their competitors.

Is IBM XIV still relevant?

Bottom line, I probably wont be getting any holiday cards from many IBM or XIV folks along with some of their die hard supporters, however it is what it is and I have said what I have to say for now while continuing to listening as well as following the progress of the solution.

Ultimately you will be the judge of if XIV is still relevant, cast your vote here.

Here are some additional resource links:

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).

Ok, nuff said.

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!

ILM = Has It Losts its Meaning

Disclaimer, warning, be advised, heads up, disclosure, this post is partially for fun so take it that way.

Remember ILM, that is, Information Lifecycle Management among other meanings.

It was a popular buzzword de jour a few years ago similar to how cloud is being tossed around lately, or in the recent past, virtualization, clusters, grids and SOA among others.

One of the challenges with ILM besides its overuse and thus confusion was what it meant, after all was or is it a product, process, paradigm or something else?

That depends of course on who you talk to and their view or definition.

For some, ILM was a new name for archiving, or storage and data tiering, or data management, or hierarchical storage management (HSM) or system managed storage (SMS) and software managed storage (SMS) among others.

So where is ILM today?

Better yet, what does ILM stand for?

Well here are a few thoughts; some are oldies but goodies, some new, some just for fun.

ILM = I Like Marketing or Its a Lot of Marketing or Its a Lot of Money
ILM = It Losts its Meaning or Its a Lot of Meetings
ILM = Information Loves Magnetic media or I Love Magnetic media
ILM = IBM Loves Mainframes or Intel Loves Memory
ILM = Infrastructure Lifecycle Management or iPods/iPhones Like Macintosh

Then there are many other variations of xLM where I is replaced with X (similar to XaaS) where X is any letter you want or need for a particular purpose or message theme. For example, how about replacing X with an A for Application Lifecycle Management (ALM), or a B for Buzzword or Backup Lifecycle Management (BLM), C for Content Lifecycle Management (CLM) and D for Document or Data Lifecycle Management (DLM). There are many others including Hardware Lifecycle Management (HLM), Product or Program Lifecycle Management (PLM) not to mention Server, Storage or Security Lifecycle Management (SLM).

While ILM or xLM specific product and marketing buzz for the most part has subsided, perhaps it is about time to reappear to give current buzzwords such as cloud a bread or rest. After all, ILM and xLM as buzzwords should be well rested after their break at the Buzzword Rest Spa (BRS) perhaps located on someday isle. You know about someday isle dont you? Its that place of dreams, a visionary place to be visited in the future.

There are already signs of the impending rested, rejuvenated and re branded appearance of ILM in the form of automated tiering, intelligent storage and data management, file virtualization, policy managed server and storage among others.

Ok, nuff said.

Going Rouge or Rogue in IT

Given all of the hype and buzz lately around Sarah Palins new book Going Rogue, how long until we see the term or phrase used in IT? After all, we saw some jump on the cash for clunkers theme. I wonder who will be the first to jump on the Going Rogue or rogue theme bandwagon. Here are a few ideas that might stimulate some thought, or, to keep an eye out to see who jumps on the bandwagon.

Going rogue on Acadia
Going rogue on Analysts
Going rogue on Archiving
Going rogue on Automated tiering
Going rogue on Backup
Going rogue on Blade servers
Going rogue on Bloggers
Going rogue on Clouds (public or private)
Going rogue on Compliance
Going rogue on Consultants
Going rogue on Dedupe
Going rogue on Disks drives
Going rogue on FCoE
Going rogue on FLASH or SSD
Going rogue on Green IT
Going rogue on Hosting
Going rogue on IOV
Going rogue on iSCSI
Going rogue on Kindle
Going rogue on Managed service providers (MSP)
Going rogue on Media venues or reporters
Going rogue on Networking
Going rogue on OSD
Going rogue on Performance
Going rogue on Polls and surveys
Going rogue on RAID
Going rogue on Security
Going rogue on SOA
Going rogue on Social media
Going rogue on Tape
Going rogue on Testing
Going rogue on Thin provision
Going rogue on Training and certifications
Going rogue on Twitter
Going rogue on VCE
Going rogue on Vendors
Going rogue with Virtualization
Going rogue on Virtual machines
Going rogue on VMware or HyperV
Going rogue on VoIP
Going rogue on Windows
Going rogue with XaaS

Alright, enough is enough for now at the risk of being perceived as snarky, after all, this is also just in fun.

Lets sit back and see who comes up with something about going rogue from an IT perspective.

Did HP respond to EMC and Cisco VCE with Microsoft HyperV bundle?

Last week EMC and Cisco along with Intel and VMware created the VCE collation along with a consumption model based service joint venture called Acadia.

In other activity last week, HP made several announcements including:

  • Improvements in sensing technologies
  • StorageWorks enhancements (SVSP, IBRIX, EVA and HyperV, X9000 and others)

EMC and Cisco were relatively quiet this week on announcement front, however HP unleashed another round of announcements that among others included:

  • Quarterly financial results
  • SMB server, storage, network and virtualization enhancements (here, here, here and here)
  • Acquisitions of 3COM (see related blog post here)

The reason I bring up all of this HP activity is not to simply re-cap all of the news and announcements which you can find on many other blogs or news sites, rather I see as a trend.

That trend appears to be one of a company on the move, not ready to sit back on its laurels, rather a company that continues to innovate in-house and via acquisitions.

Some of those acquisitions including IBRIX were relatively small, some like EDS last year and the one this week of 3COM to some would be large while to others perhaps as being seen as medium sized. Either way, HP has been busy expanding its portfolio of technology solution and services offerings along with its comprehensive IT stack.

Cisco, EMC and HP are examples of companies looking to expand their IT stacks and footprint in terms of diversifying current product focus and reach, along with extending into new or further into existing customer and market sector areas. Last weeks EMC and Cisco signaled two large players combing their resources to make virtualization and private clouds easy to acquire and deploy for mid to large size environments with a theme around VMware.

This week buried in all of the HP announcements was one that caught my eye which is a virtualization solution bundle designed for small business (that is something smaller than a vblock0), something that was missing in the Cisco and EMC news of last week however one that Im sure will be addressed sooner versus later.

In the case of HP, the other thing with their virtualization bundle was the focus on the mid to small business that fall into the broad and diverse SMB category, not to mention including Microsoft.

Yes, that is right, while a VMware based solution from HP would be a no-brainer given all of the activity the two companies are involved  in as joint partners, Microsoft HyperV was front and center.

Is this a reaction to last weeks Cisco and EMC salvo?

Perhaps and some will jump to that conclusion. However I will also offer this alternative scenario, 85-90 percent of servers consolidated into virtual machines (VMs) on VMware or other hypervisors including Microsoft HyperV are Windows based.

Likewise as one of the largest if not largest server vendors (pick your favorite server category or price band) who also happens to be one of the largest Microsoft Windows partners, I would have been more surprised if HP had not done a HyperV bundle.

While Cisco and EMC may stay the course or at least talk the talk with a VMware affinity in the Acadia and VCE coalition for the time being, I would expect HP to flex its wings a bit and show diversity of support for multiple Hypervisors, Operating Systems across its various server, network, storage and services platforms.

I would not be surprised to see some VMware based bundles appear over time building on previous announced HP blade systems matrix solution bundles.

Welcome back my friends to the show that never ends, that is the on-going server, storage, networking, virtualization, hardware, software and services solutions game for enabling the adaptive, dynamic, flexible, scalable, resilient, service oriented, public or private cloud, infrastructure as a service green and virtual data center.

Stay tuned, there is much more to come!

Ok, nuff said.
