2012 industry trends perspectives and commentary (predictions)

2011 is almost over, so its wrap up time of the year as well as getting ready for 2012.

Here is a link to a post of the top 25 new posts that appeared on StorageIOblog in 2011.

As a companion to the above, here is a link to the all time top 25 posts from StorageIOblog.

Looking back, here is a post about industry trends, thoughts and perspective predictions for 2010 and 2011 (preview 2012 and 2013 thoughts and perspectives here).

Im still finalizing my 2012 and 2013 predictions and perspectives which is a work in progress, however here is a synopsis:

  • Addressing storage woes at the source: Time to start treating the source of data management and protection including backup challenges instead of or in addition to addressing downstream target destination topics.
  • Big data and big bandwidth meet big backup: 2011 was a buzz with big data and big bandwidth so 2012 will see realization that big backup needs to be addressed. Also in 2012 there will be continued realization that many have been doing big data and big bandwidth thus also big backups for many years if not decades before the current big buzzword became popular.
  • Little data does not get left out of the discussion even though younger brother big data gets all of the press and praise. Little data may not be the shining diva it once was, however the revenue annuity stream will keep many software, tools, server and storage vendors afloat while customers continue to rely on the little data darling to run their business.
  • Cloud confusion finds clarity on the horizon: Granted there will be plenty of more cloud fud and hype, cloud washing and cleaning going around, however 2012 and beyond will also find organizations realizing where and how to use different types of clouds (public, private, hybrid) too meet various needs from SaaS and AaaS to PaaS to IaaS and other variations of XaaS. Part of the clarification that will help remove the confusion will be that there are many different types of cloud architectures, products, stacks, solutions, services and products to address various needs. Another part of the clarification will be discussion of what needs to be added to clouds to make them more viable for both new, as well as old or existing applications. This means organizations will determine what they need to do to move their existing applications to some form of a cloud model while understanding how clouds coexist and compliment what they are currently doing. Cloud conversations will also shift from low cost or for free focus expanding to discussions around value, trust, quality of service (QoS), SLOs, SLAs, security, reliability and related themes.

Industry Trends and Perspectives

  • Cloud and virtualization stack battles: The golden rule of virtualization and clouds is that who ever controls the management and software stacks controls the gold. Hence, watch for more positioning around management and enablement stacks as well as solutions to see who gains control of the gold.
  • Data protection modernization: Building off of first point above, data protection modernization the past several years has been focused on treating the symptoms of downstream problems at the target or destination. This has involved swapping out or moving media around, applying data footprint reduction (DFR) techniques downstream to give near term tactical relief as has been the cause with backup, restore, BC and DR for many years. Now the focus will start to expand to how to address the source of the problem with is an expanding data footprint upstream or at the source using different data footprint reduction tools and techniques. This also means using different metrics including keeping performance and response time in perspective as part of reduction rates vs. ratios while leveraging different techniques and tools from the data footprint reduction tool box. In other words, its time to stop swapping out media like changing tires that keep going flat on a car, find and fix the problem, change the way data is protected (and when) to cut the impact down stream. This will not happen overnight, however with virtualization and cloud activities underway, now is a good time to start modernizing data protection.
  • End to End (E2E) management tools: Continue focus around E2E tools and capabilities to gain situational awareness across different technology layers.
  • FCoE and Fibre Channel continue to mature: One sure sign that Fibre Channel over Ethernet (FCoE) is continuing to evolve, mature and gain initial traction is the increase in activity declaring it dead or dumb or similar things. FCoE is still in its infancy while Fibre Channel (FC) is in the process of transitioning to 16Gb with a roadmap that will enable it to continue for many more years. As FCoE continues to ramp up over next several years (remember, FC took several years to get where it is today), continued FC enhancements will give options for those wishing to stick with it while gaining confidence with FCoE, iSCSI, SAS and NAS.
  • Hard drive shortages drive revenues and profits: Some have declared that the recent HDD shortages due to Thailand flooding will cause Solid State Devices (SSD) using flash memory to dramatically grow in adoption and deployment. I think that both single level cell (SLC) and multi level cell (MLC) flash SSDs will continue to grow in deployments counted in units shipped as well as revenues and hopefully also margin or profits. However I also think that with the HDD shortage and continued demand, vendors will use the opportunity to stabilize some of their pricing meaning less discounting while managing the inventory which should mean more margin or profits in a quarter or too. What will be interesting to watch will be if SSD vendors drop the margin in an effort to increase units shipped and deployed to show market revenue and adoption growth while HDD margins rise.

Industry Trends and Perspectives

  • QoS, SLA/SLOs part of cloud conversations: Low cost or cost avoidance will continue to be the focus of some cloud conversations. However with metrics and measurements to make informed decisions, discussions will expand to QoS, SLO, SLAs, security, mean time to restore or return information, privacy, trust and value also enter into the picture. In other words, clouds are growing up and maturing for some, while their existing capabilities become discovered by others.
  • Clouds are a shared responsibility model: The cloud blame game when something goes wrong will continue, however there will also be a realization that as with any technology or tool, there is a shared responsibility. This means that customers accept responsibility for how they will use a tool, technologies or service, the provider assumes responsibility, and both parties have a collective responsibility.
  • Return on innovation is the new ROI: For years, no make that decades a popular buzz term is return on investment the companion of total cost of ownership. Both ROI and TCO as you know and like (or hate) will continue to be used, however for situations that are difficult to monitize, a new variation exists. That new variation is return on innovation which is the measure of intangible benefits derived from how hard products are used to derive value for or of soft products and services delivered.
  • Solid State Devices (SSD) confidence: One of the barriers to flash SSD adoption has been cost per capacity with another being confidence in reliability and data consistency over time (aka duty cycle wear and tear). Many enterprise class solutions have used single level cell (SLC) flash SSD which has better endurance, duty cycle or wear handing capabilities however that benefit comes at the cost of a higher price per capacity. Consequently vendors are pushing multi level cell (MLC) flash SSD that reduces the cost per capacity, however needs extra controller and firmware functionality to manage the wear leaving and duty cycle. In some ways, MLC flash is to SSD memory what SATA high-capacity desktop drives were to HDDs in the enterprise storage space about 8 to 9 years ago. What I mean by that is that more cost high performance disk drives were the norm, then lower cost higher capacity SATA drives appeared resulting in enhancements to make them more enterprise capable while boosting the confidence of customers to use the technology. Same thing is happening with flash SSD in that SLC is more expensive and for many has a higher confidence, while MLC is lower cost, higher capacity and gaining the enhancements to take on a role for flash SSD similar to what high-capacity SATA did in the HDD space. In addition to confidence with SSD, new packaging variations will continue to evolve as well.
  • Virtualization beyond consolidation: The current wave of consolidation of desktop using VDI, server and storage aggregation will continue, however a trend that has grown for a couple of years now that will take more prominence in 2012 and 2013 is realization that not everything can be consolidated, however many things can be virtualized. This means for some applications the focus will not be how many VMs to run per PM, rather, how a PM can be more effectively used to boost performance and agility for some applications during part of the day, while being used for other things at different times. For example a high performance database that normally would not be consolidated would be virtualized to enable agility for maintenance, BC, DR load balancing and placed on a fast PM with lots of fast memory, CPU and IO capabilities dedicated to it. However during off hours when little to no database activity is occurring, then other VMs would be moved onto that PM then moved off before the next busy cycle.

Industry Trends and Perspectives

  • Will applications be ready to leverage cloud: Some applications and functionality can more easily be moved to cloud environments vs. others. A question that organizations will start to ask is what prevents their applications or business functionality from going to or using cloud resources in addition to asking cloud providers what new capabilities will they extend to support old environments.
  • Zombie list grows: More items will be declared dead meaning that they are either still alive, or have reached stability to the point where some want to see them dead so that their preferred technology or topic can take root.
  • Some other topics and trends include continued growing awareness that metrics and measurements matter for cloud, virtualization, data and storage networking. This also means a growing awareness that there are more metrics that matter for storage than cost per GByte or Tbyte that include IOPS, latency or response time, bandwidth, IO size, random and sequential along with availability. 2012 and 2013 will see continued respect being given to NAS at both the high end as well as low end of the market from enterprise down to consumer space. Speaking of consumer and SOHO (Small Office Home Office), now that SMB has generally been given respect or at least attention by many vendors, the new frontier will be to move further down market to the lower end of the SMB which is SOHO, just above consumer space. Of course some vendors have already closed the gap (or at least on paper, power point, web ex or you tube video) from consumer to enterprise. Of course Buzzword bingo will continue to be a popular game.
  • Oh, btw, DevOps will also appear in your vocabulary if it has not already.

New Seagate Momentus XT Hybrid drive (SSD and HDD)

Seagate recently announced the next generation Momentus XT Hybrid Hard Disk Drive (HHDD) with a capacity of 750GB in a 2.5 inch form factor and MSRP of $245.00 USD including integrated NAND flash solid state device (SSD). As a refresher, the Momentus XT is a HHDD in that it includes a 4GB nand flash SSD integrated with a 500GB (or larger) 7,200 RPM hard disk drive (HDD) in a single 2.5 inch package.

This is the fifth installment of a series that I have done since June 2010 when I received my first HHDD a Seagate Momentus XT. You can read the other installments of my momentus moments here, here, here and here.

Whats is new with the new generation.
Besides extra storage space capacity up to 750GB (was 500GB), there is twice as much single level cell (SLC) nand flash memory (8GB vs. 4GB in previous generation) along with an enhanced interface using 6Gb per second SATA that supports native command queuing (NCQ) for better performance. Note that NCQ was available on the previous generation Momentus XT that used a 3Gb SATA interface. Other enhancements include a larger block or sector size of 4096 bytes vs. traditional 512 bytes on previous generation storage devices.

This bigger sector size results in less overhead with managing data blocks on large capacity storage devices. Also new are caching enhancements are FAST Factor Flash Management, FAST Factor Boot and Adaptive Memory Technology. Not to be confused with EMC Fully Automated Storage Tiering the other FAST; Seagate FAST is technology that exists inside the storage drive itself. FAST Factor boot enables systems to boot and be productive with speeds similar to SSD or several times faster than traditional HDDs.

The FAST Factor Flash Management provides the integrated intelligence to maximize use of the nand flash or SSD capabilities along with spinning HDD to boot performance, keep up compatibility with different systems and their operating systems. In addition to performance and interoperability, data integrity and SSD flash endurance are also enhanced for investment protection. The Adaptive Memory technology is a self learning algorithm to give SSD like performance for often used applications and data to close the storage capacity too performance gap that has increased along with data center bottlenecks.

Some questions and discussion comments:

When to use SSD vs. HDD vs. HHDD?
If you need the full speed of SSD to boost performance across all data access and cost is not an issue for available capacity that is where you should be focused. However if you are looking for lowest total cost of storage capacity with no need for performance, than lower cost high capacity HDDs should be on your shopping list. On the other hand, if you want a mix of performance and capacity at an effective price, than HHDDs should be considered.

Why the price jump compared to first generation HHDD?
IMHO, it has a lot to do with current market conditions, supply and demand.

With recent floods in Thailand and forecasted HDD and other technology shortages, the lay of supply and demand applies. This means that the supply may be constrained for some products causing demand to rise for others. Your particular vendor or supplier may have inventory however will be less likely to heavily discount while there are shortages or market opportunities to keep prices high. There are already examples of this if you check around on various sites to compare prices now vs. a few months ago. Granted it is the holiday shopping season for both people as well as organizations spending the last of their available budgets so more demand for available supplies.

What kind of performance or productivity have I seen with HHDDs?
While I have not yet tested and compared the second generation or new devices, I can attest to the performance improvements resulting in better productivity over the past year using Seagate Momentus XT HHDDs compared to traditional HDDs. Here is a post that you can follow to see some boot performance comparisons as part of some virtual desktop infrastructure (VDI) sizing testing I did earlier this year that included both HHDD and HDD.

When will I jump on the SSD bandwagon?
Great question, I have actually been on the SSD train for several decades using them, selling them, covering, analyzing and consulting around them along with other storage mediums including HDD, HHDD, cloud and tape. I have some SSDs and will eventually put them into my laptops, workstations and servers as primary storage when the opportunity makes sense.

Will HHDDs help backup and other data protection tasks?
Yes, in fact I initially used my Momentus XTs as backup or data protection targets along with for moving large amounts of data between systems faster than what my network could support.

Why not use a SSD?
If you need the performance and can afford the price, go SSD!

On the other hand, if you are looking to add a small 64GB, 128GB or even 256GB SSD while retaining a larger capacity, slower and lower cost HDD, an HHDD should be considered as an option. By using an HHDD instead of both a SSD and HDD, you will cut the need of figuring out how to install both in space constrained laptops, desktop or workstations. In addition, you will cut the need to either manually move data between the different devices or avoid having to acquire software or drivers to do that for you.

How much does the new Seagate Momentus XT HHDD cost?
Manufactures Suggested Retail Price (MSRP) is listed at $245 for a 750GB version.

Does the Momentus XT HHDD need any special drivers, adapters or software?
No, they are plug and play. There is no need for caching or performance acceleration drivers, utilities or other software. Likewise no needs for tiering or data movement tools.

How do you install an HHDD into an existing system?
Similar to installing a new HDD to replace an existing one if you are familiar with that process. If not, it goes like this (or uses your own preferred approach).

  • Attach a new HHDD to an existing system using a cable
  • Utilize a disk clone or image tool to make a copy of the existing HDD to HHDD
  • Note that the system may not be able to be used during the copy, so plan ahead.
  • After the clone or image copy is made, shutdown system, remove existing HDD and replace it with the HHDD that was connected to the system during the copy (remember to remove the copy cable).
  • Reboot the system to verify all is well, note that it will take a few reboots before the HHDD will start to learn your data and files along with how they are used.
  • Regarding your old HDD, save it, put it in a safe place and use it as a disaster recovery (DR) backup. For example if you have a safe deposit box or somewhere else safe, put it there for when you will need it in the future.


Seagate Momentus XT and USB to SATA cable

Can an HHDD fit into an existing slot in a laptop, workstation or server?
Yes. In fact, unlike a HDD and SSD combination, that requires multiple slots or forcing one device to be external, HHDDs like the Momentus XT simply use the space where your current HDD is installed.

How do you move data to it?
Beyond the first installation described above, the HHDD appears as just another local device meaning you can move data to or from it like any other HDD, SSD or CD.

Do you need automated tiering software?
No, not unless you need it for some other reason or if you want to use an HHDD as the lower cost, larger capacity option as a companion to a smaller SSD.

Do I have any of the new or second generation HHDDs?
Not yet, maybe soon and I will do another momentus moment point when that time arrives. For the time being, I will continue to use the first generation Momentus XT HHDDs

Bottom line (for now), If you are considering a large capacity, HDDs check out the HHDDs for an added performance boost including faster boot times as well as accessing other data quicker.

On the other hand if you want an SSD however your budget restricts you to a smaller capacity version, look into how an HHDD can be a viable option for some of your needs.

Measuring Windows performance impact for VDI planning

Here is a link to a recent guest post that I was invited to do over at The Virtualization Practice (TVP) pertaining to measuring the impact of Windows Boot performance and what that means for planning for Virtual Desktop Infrastructure (VDI) initiatives.

With Virtual Desktop Infrastructures (VDI) initiatives adoption being a popular theme associated with cloud and dynamic infrastructure environments a related discussion point is the impact on networks, servers and storage during boot or startup activity to avoid bottlenecks. VDI solution vendors include Citrix, Microsoft and VMware along with various server, storage, networking and management tools vendors.

A common storage and network related topic involving VDI are boot storms when many workstations or desktops all startup at the same time. However any discussion around VDI and its impact on networks, servers and storage should also be expanded from read centric boots to write intensive shutdown or maintenance activity as well.

Having an understanding of what your performance requirements are is important to adequately design a configuration that will meet your Quality of Service (QoS) and service level objectives (SLOs) for VDI deployment in addition to knowing what to look for in candidate server, storage and networking technologies. For example, knowing how your different desktop applications and workloads perform on a normal basis provides a baseline to compare with during busy periods or times of trouble. Another benefit is that when shopping for example storage systems and reviewing various benchmarks, knowing what your actual performance and application characteristics are helps to align the applicable technology to your QoS and SLO needs while avoiding apples to oranges benchmark comparisons.

Check out the entire piece including some test results using the hIOmon tool from hyperIO to gather actual workstation performance numbers.

Keep in mind that the best benchmark is your actual applications running as close to possible to their typical workload and usage scenarios.

Also keep in mind that fast workstations need fast networks, fast servers and fast storage.

StorageIO Momentus Hybrid Hard Disk Drive (HHDD) Moments

This is the third in a series of posts that I have done about Hybrid Hard Disk Drives (HHDDs) along with pieces about Hard Disk Drives (HDD) and Solid State Devices (SSDs). Granted the HDD received its AARP card several years ago when it turned 50 and is routinely declared dead (or read here) even though it continues to evolve along SSD maturing and both expanding into different markets as well as usage roles.

For those who have not read previous posts about Hybrid Hard Disk Drives (HHDDs) and the Seagate Momentus XT you can find them here and here.

Since my last post, I have been using the HHDDs extensively and recently installed the latest firmware. The release of new HHDD firmware by Seagate for the Momentus XT (SD 25) like its predecessor SD24 cleaned up some annoyances and improved on overall stability. Here is a Seagate post by Mark Wojtasiak discussing SD25 and feedback obtained via the Momentus XT forum from customers.

If you have never done a HDD firmware update, its not as bad or intimidating as might be expected. The Seagate firmware update tools make it very easy, that is assuming you have a recent good backup of your data (one that can be restored) and about 10 to 15 minutes of time for a couple of reboots.

Speaking of stability, the Momentus XT HHDDs have been performing well helping to speed up accessing large documents on various projects including those for my new book. Granted an SSD would be faster across the board, however the large capacity at the price point of the HHDD is what makes it a hybrid value proposition. As I have said in previous posts, if you have the need for speed all of the time and time is money, get an SSD. Likewise if you need as much capacity as you can get and performance is not your primary objective, then leverage the high capacity HDDs. On the other hand, if you need a balance of some performance boost with capacity boost and a good value, then check out the HHDDs.

Lets shift gears from that of the product or technology to that of common questions that I get asked about HHDDs.

Common questions I get asked about HHDDs include:

What is a Hybrid Hard Disk Drive?

A Hybrid Hard Disk Drive includes a combination of rotating HDD, solid state flash persistent memory along with volatile dynamic random access memory (DRAM) in an integrated package or product. The value proposition and benefit is a balance of performance and capacity at a good price for those environments, systems or applications that do not need all SSD performance (and cost) vs. those that need some performance in addition to large capacity.

How the Seagate Momentus XT differs from other Hybrid Disks?
One approach is to take a traditional HDD and pair it with a SSD using a controller packaged in various ways. For example on a large scale, HDDs and SSDs coexist in the same tiered storage system being managed by the controllers, storage processors or nodes in the solution including automated tiering and cache promotion or demotion. The main difference however between other storage systems, tiering and pairing and HHDDs is that in the case of the Momentus XT the HDD, SLC flash (SSD functionality) and RAM cache and their management are all integrated within the disk drive enclosure.

Do I use SSDs and HDDs or just HHDDs?
I have HHDDs installed internally in my laptops. I also have HDDs which are installed in servers, NAS and disk to disk (D2D) backup devices and Digital Video Recorders (DVRs) along with external SSD and Removable Hard Disk Drives (RHDDs). The RHDDs are used for archive and master or gold copy data protection that go offsite complimenting how I also use cloud backup services as part of my data protection strategy.

What are the technical specifications of a HHDD such as the Seagate Momentus XT?
3Gbs SATA interface, 2.5 inch 500GB 7,200 RPM HDD with 32MB RAM cache and integrated 4GByte SLC flash all managed via internal drive processor. Power consumption varies depending what the device is doing such as initial power up, idle, normal or other operating modes. You can view the Seagate Momentus XT 500GB (ST95005620AS which is what I have) specifications here as well as the product manual here.

Do you need a special controller or management software?
Generally speaking no, the HHDD that I have been using plugged and played into my existing laptops internal bay replacing the HDD that came with those systems. No extra software was needed for Windows, no data movement or migration tools needed other than when initially copying from the source HDD to the new HHDD. The HHDD do their own caching, read ahead and write behind independent of the operating system or controller. Now the reason I say generally speaking is that like many devices, some operating systems or controllers may be able to leverage advanced features so check your particular system capabilities.

How come the storage system vendors are not talking about these HHDDs?
Good question which I assume it has a lot to do with the investment (people, time, engineering, money and marketing) that they have or are making in controller and storage system software functionality to effectively create hybrid tiered storage systems using SSD and HDDs on different scales. There have been some packaged HHDD systems or solutions brought to market by different vendors that combine HDD and SSD into a single physical package glued together with some software and controllers or processors to appear as a single system. I would not be surprised to see discrete HHDDs (where the HDD and flash SSD and RAM are all one integrated product) appear in lower end NAS or multifunction storage systems as well as for backup, dedupe or other system that requires large amounts of capacity space and performance boost now and then.

Why do I think this? Simple, say you have five HHDDs each with 500GB of capacity configured as a RAID5 set resulting in 2TByte of capacity. Using as a hypothetical example the Momentus XT yields 5 x 4GByte or 20GByte of flash cache helps accelerate write operations during data dumps, backup or other updates. Granted that is an overly simplified example and storage systems can be found with hundreds of GByte of cache, however think in terms of value or low cost balancing performance and capacity to cost for different usage scenarios. For example, applications such as bulk or scale out file and object storage including cloud or big data, entertainment, Server (Citrix/Xen, Microsoft/HyperV, VMware/vSphere) and Desktop virtualization or VDI, Disk to Disk (D2D) backup, business analytics among others. The common tenets of those applications and usage scenario is a combination of I/O and storage consolidation in a cost effective manner addressing the continuing storage capacity to I/O performance gap.

Do you have to backup HHDDs?
Yes, just as you would want to backup or protect any SSD or HHD device or system.

How does data get moved between the SSD and the HDD?
Other than the initial data migration from the old HDD (or SSD) to the HHDD, unless you are starting with a new system, once your data and applications exist on the HHDD, it automatically via the internal process of the device manages the RAM, flash and HDD activity. Unlike in a tiered storage system where data blocks or files may be moved between different types of storage devices, inside the HHDD, all data gets written to the HDD, however the flash and RAM are used as buffers for caching depending on activity needs. If you have sat through or listened to a NetApp or HDS use of cache for tiering discussion what the HHDDs do is similar in concept however on a smaller scale at the device level, potentially even in a complimentary mode in the future? Other functions performed inside the HHDD by its processor includes reading and writing, managing the caches, bad block replacement or re vectoring on the HDD, wear leveling of the SLC flash and other routine tasks such as integrity checks and diagnostics. Unlike paired storage solutions where data gets moved between tiers or types of devices, once data is stored in the HHDD, it is managed by the device similar to how a SSD or HDD would move blocks of data to and from the specific media along with leveraging RAM cache as a buffer.

Where is the controller that manages the SSD and HDD?
The HHDD itself is the controller per say in that the internal processor that manages the HDD also directly access the RAM and flash.

What type of flash is used and will it wear out?
The XT uses SLC (single level cell) flash which with wear leveling has a good duty cycle (life span) and is what is typically found in higher end flash SSD solutions vs. lower cost MLC (multi level cell)

Have I lost any data from it yet?
No, at least nothing that was not my own fault from saving the wrong file in the wrong place and having to recover from one of my recent D2D copies or the cloud. Oh, regarding what have I done with the HDDs that were replaced by the HHDDs? They are now an extra gold master backup copy as of a particular point in time and are being kept in a safe secure facility, encrypted of course.

Have you noticed a performance improvement?
Yes, performance will vary however in many cases I have seen performance comparable to SSD on both reads and writes as long as the HDDs keep up with the flash and RAM cache. Even as larger amounts of data are written, I have seen better performance than compared to HDDs. The caveat however is that initially you may see little to marginal performance improvement however over time, particularly on the same files, performance tends to improve. Working on large tens to hundreds of MByte size documents I noticed good performance when doing saves compared to working with them on a HDD.

What do the HHDDs cost?
Amazon.com has the 500GB model for about $100 which is about $40 to $50 less than when I bought my most recent one last fall. I have heard from other people that you can find them at even lower prices at other venues. In the theme of disclosures, I bought one of my HHDDs from Amazon and Seagate gave me one to test.

Will I buy more HHDDs or switch to SSDs?
Where applicable I will add SSDs as well as HDDs, however where possible and practical, I will also add HHDDs perhaps even replacing the HDDs in my NAS system with HHDDs at some time or maybe trying them in a DVR.

What is the down side to the HHDDs?
Im generating and saving more data on the devices at a faster rate which means that when I installed them I was wondering if I would ever fill up a 500GB drive. I still have hundreds of GBytes free or available for use, however I also am able to cary more reference data or information than in the past. In addition to more reference data including videos, audio, images, slide decks and other content, I have also been able to keep more versions or copies of documents which has been handy on the book project. Data that changes gets backed up D2D as well as to my cloud provider including while traveling. Leveraging compression and dedupe, given that many chapters or other content are similar, not as much data actually gets transmitted when doing cloud backups which has been handy when doing a backup from a airplane flying over the clouds. A wish for the XT type of HHDD that I have is for vendors such as Seagate to add Self Encrypting Disk (SED) capabilities to them along with applying continued intelligent power management (IPM) enhancements.

Why do I like the HHDD?
Simple, it solves both business and technology challenges while being an enabler, it gives me a balance of performance for productivity and capacity in a cost effective manner while being transparent to the systems it works with.

End to End (E2E) Systems Resource Analysis (SRA) for Cloud and Virtual Environments

A new StorageIO Industry Trends and Perspective (ITP) white paper titled “End to End (E2E) Systems Resource Analysis (SRA) for Cloud, Virtual and Abstracted Environments” is now available at www.storageio.com/reports compliments of SANpulse technologies.

End to End (E2E) Systems Resource Analysis (SRA) for Virtual, Cloud and abstracted environments: Importance of Situational Awareness for Virtual and Abstracted Environments

Abstract:
Many organizations are in the planning phase or already executing initiatives moving their IT applications and data to abstracted, cloud (public or private) virtualized or other forms of efficient, effective dynamic operating environments. Others are in the process of exploring where, when, why and how to use various forms of abstraction techniques and technologies to address various issues. Issues include opportunities to leverage virtualization and abstraction techniques that enable IT agility, flexibility, resiliency and salability in a cost effective yet productive manner.

An important need when moving to a cloud or virtualized dynamic environment is to have situational awareness of IT resources. This means having insight into how IT resources are being deployed to support business applications and to meet service objectives in a cost effective manner.

Awareness of IT resource usage provides insight necessary for both tactical and strategic planning as well as decision making. Effective management requires insight into not only what resources are at hand but also how they are being used to decide where different applications and data should be placed to effectively meet business requirements.

Learn more about the importance and opportunities associated with gaining situational awareness using E2E SRA for virtual, cloud and abstracted environments in this StorageIO Industry Trends and Perspective (ITP) white paper compliments of SANpulse technologies by clicking here.

CMG, Enabling “The Green and Virtual Data Center”

Storage I/O trends

Last week I was invited to by Tom Becchetti and the Minneapolis CMG folks to keynote at their session hosted at the Brocade facity in Minneapolis along with other speakers from Brocade, IBM, Teamquest and Sun.

The theme of my talk was “The Green and Virtual Data Center and The Importance of Metrics” which can be downloaded here.

I have been a member of CMG for many years as a former performance and capacity planning analyst when I worked in IT organizations and having presented at many CMG events around the world. While CMG has been around for many decades and has seen its share of ups and downs. With a current focus on boosting use, maximizing resource usage, improving service delivery and performance while using less energy in smaller footprints, now is the perfect opportunity for CMG to re-invent itself and show relevance as the organization that knows how to measure, watch, model and manage resource usage and service delivery effectiveness across different technology domains including servers, storage, networks, applications, operating systems and facilities. There is a golden opportunity for CMG members to step up and leverage their skills across different technology domains working with others to establish metrics, models and baselines.

In my new book, “The Green and Virtual Data Center” (Auerbach) I include a chapter on metrics and measurement as well as many other topics and themes that tie into the notion of effective and efficient data centers need to carry out Infrastructure Resource Management (IRM) which is also a chapter in the book, that includes performance and capacity planning across technology domains.

Watch for more on this topic.
