Supreme Court Rules Sarbox intact, Oversight Board Changes

Today the US Supreme Court ruled on a Nevada case involving constitutionality of the 2002 Sarbanes-Oxley (Sarbox) accounting regulations pertaining to appointments to the independent public company accounting oversight board.

The Supreme Court ruled that the Sarbox regulations or law remains intact, however the process or controls around the oversight board must change.

My interpretation and perspective from reading a few different reports is that Sarbox as you know and love (or hate) it is essentially still intact. However what has changed or will be is that individual board members can now be removed or at least in an easier manner. Instead of the request to strike down the Sarbox regulations, the Supreme Court instead appears to have left the regulations intact instead ruling that board members can be changed or removed.

What does this all mean?

Perhaps not much other than firms who have been making money on Sarbox now having something else to talk or consult about (Hmmm, a Sarbox stimulus?).

On the other hand, with the ability to have Sarbox board members more easily removed, perhaps we will see a new board installed that could influence the thinking and thus applicability of Sarbox activity.

Near term, I can see this as being non news for some, and for others, confusion and lets not forget that in chaos or confusion there is opportunity.

Initial Virtumania Appearance (Episode 14) with fellow vExperts

This past week I was invited to join some fellow vExperts as a first time guest on Rich Brambleys (@rbrambley and VMETC) podcast show called Virtumania.

Episode 14 (Virtualization and Networking Turf Wars) had as a theme as you can guest themes around physical, logical and virtual networking for virtual servers along with some of the politics and turf battles associated with managing those entities.

Also on the show were cohost Marc Farley (@3parfarley) of 3Par and StorageRap.com as well as regular guest Rick Vanover (@rickvanover) of RickVanover.com and other special guest David Davis (@davidmdavis) vmwarevideos.com in addition to myself.

For some fun, there is even some reference to rival gangs dancing for superiority in the Michael Jackson music video "Bad" which was produced by Greg Knieriemen (@knieriemen) of Chi Corporation for this Infosmack Production.

Check out the show here or here.

BTW: Is it just me or does Rich Brambley sound a little bit like Tom Petty without the accent?

Thanks guys, enjoyed being a guest on the show as well as talking with you all, hope to be able to do it again sometime soon.

Industry Trends and Perspectives: Public and Private IT Clouds

This is part of an ongoing series of short industry trends and perspectives blog posts briefs.

These short posts compliment other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageioblog.com/reports.

Are you clear on cloud conversation issues, topics and trends? Or, are you confused and looking for clarification of what is (or not) a public vs. private cloud? If you are part of the second group, welcome to the majority of IT professionals that includes customers as well as some VARs and vendors not to mention press, media or bloggers as well as analysts and other industry pundits.

A couple of customer trends that Im seeing are that public clouds in terms of backup as a service (BaaS), Backup Service Provider (BSP), Managed Service Provider (MSP), Cloud Backup Service (CBS) or hosted backup among other terms or acronyms continues to be popular for smaller consumer, SOHO and SMB as well as ROBO environments with some larger scale adoption. Likewise there continues to be some early adoption of cloud archive however this is mainly as a storage target or medium where data goes.

Some vendors or VARs are touting cloud archive as the silver bullet for cloud adoption however unless they can address the fundamental archive challenge all they are doing is competing on price to shift the location of where data gets parked. The real archive challenge is not necessarily the hardware where data is housed or its subsequent management, nor is the real cost or barrier archiving software for databases, email or file systems.

The real or more common barrier is that of someone identifying and approving not to mention indemnifying those involved of what can be moved when, where as well as for how long. This means that professional services and business buy in for establishment of policies along with tools for classifying applications and data are needed. Thus before automated movement and migration tools to leverage various tiers of local and remote including cloud archive storage can be used, the fundamental barriers to archive need to be addressed.

Im also seeing continued skepticism in addition to confusion around clouds in general, however there is also curiosity wanting to know or learn more about clouds and traditional IT coexisting. Consequently Im seeing while still low, more interest in private clouds by IT professionals as it is closer to their real world.

The common theme around interest in private clouds is that of enhancing IT efficient and effectiveness along with service delivery. Thus there is a growing interest in identifying costs of providing a given level of service that meets various RTO, RPO, QoS and other SLA objectives.

Likewise, Im seeing more interest around public clouds by vendors, investors or some business where the focus is more around near term monetization or addressing an opportunity when seen. Public clouds tend to be more fun for the industry to talk about or speculate upon compared to legacy boring IT (at least in the minds of those outside of core IT).

There are many different types as well as definition of clouds based on various products, initiatives and viewpoints. By their nature and how clouds have been used as a metaphor or symbol for abstracting complex items in IT for decades. Consequently, similar to virtualization which also has multiple meanings it should be no surprise that there is cloud confusion. After all, in chaos and confusion there is opportunity for the industry at large to develop and provide services or products that need to be promoted and marketed which require coverage and discussion along with advice or consultation as well as implementation.

With all of the conversations around cloud as a metaphor for describing IT services, products and functions, that could beg the question of if these different approaches are a Stairway to Heaven, Hotel California (you can check in however never leave), Road to Hell or Highway to Hell or perhaps a journey to Yellow Brick Road.

My general thinking and perception of both public and private IT clouds continues to be that of dont be scared, however look before you leap. Look at how cloud IT are not a replacement, rather are a compliment to your existing environment as another tier of resource (server, storage, network, software or other service) used to address various needs or issues. Likewise is private cloud another name for in sourcing of IT?

That is all for now, hope you find this ongoing series of current and emerging Industry Trends and Perspectives interesting.

Ok, nuff said.

Industry Trends and Perspectives: Tiered Storage, Systems and Mediums

This is part of an ongoing series of short industry trends and perspectives blog posts briefs.

These short posts compliment other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageioblog.com/reports.

Two years ago we read about how the magnetic disk drive would be dead in a couple of years at the hand of flash SSD. Guess what, it is a couple of years later and the magnetic disk drive is far from being dead. Granted high performance Fibre Channel disks will continue to be replaced by high performance, small form factor 2.5" SAS drives along with continued adoption of high capacity SAS and SATA devices.

Likewise, SSD or flash drives continue to be deployed, however outside of iPhone, iPod and other consumer or low end devices, nowhere near the projected or perhaps hoped for level. Rest assured the trend Im seeing and hearing from IT customers is that some will continue to look for places to strategically deploy SSD where possible, practical and affordable, there will continue to be a roll for disk and even tape devices on a go forward basis.

Also watch for more coverage and discussion around the emergence of the Hybrid Hard Disk Drive (HHDD) that was discussed about four to five years ago. The HHDD made an appearance and then quietly went away for some time, perhaps more R and D time in the labs while flash SSD garnered the spotlight.

There could be a good opportunity for HHDD technology leveraging the best of both worlds that is continued pricing decreases for disk with larger capacity using smaller yet more affordable amounts of flash in a solution that is transparent to the server or storage controller making for easier integration.

That is all for now, hope you find this ongoing series of current and emerging Industry Trends and Perspectives interesting.

Industry Trends and Perspectives: RAID Rebuild Rates

This is part of an ongoing series of short industry trends and perspectives blog posts briefs.

These short posts compliment other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageioblog.com/reports.

There is continued concern about how long large capacity disk drives take to be rebuilt in RAID sets particularly as the continued shift from 1TB to 2TB occurs. It should not be a surprise that a disk with more capacity will take longer to rebuild or copy as well as with more drives; the likely hood of one failing statistically increases.

Not to diminish the issue, however also to avoid saying the sky is falling, we have been here before! In the late 90s and early 2000s there was a similar concern with the then large 9GB, 18GB let alone emerging 36GB and 72GB drives. There have been improvements in RAID as well as rebuild algorithms along with other storage system software or firmware enhancements not to mention boost in processor or IO bus performance.

However not all storage systems are equal even if they use the same underlying processors, IO busses, adapters or disk drives. Some vendors have made significant improvements in their rebuild times where each generation of software or firmware can reconstruct a failed drive faster. Yet for others, each subsequent iteration of larger capacity disk drives brings increased rebuild times.

If disk drive rebuild times are a concern, ask your vendor or solution provider what they are doing as well as have done over the past several years to boost their performance. Look for signs of continued improvement in rebuild and reconstruction performance as well as decrease in error rates or false drive rebuilds.

Industry Trends and Perspectives: Converged Networking and IO Virtualization (IOV)

This is part of an ongoing series of short industry trends and perspectives blog posts briefs.

These short posts compliment other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageioblog.com/reports.

The trends that I am seeing with converged networking and I/O fall into a couple of categories. One being converged networking including unified communications, FCoE/DCB along with InfiniBand based discussions while the other being around I/O virtualization (IOV) including PCIe server based multi root IO virtualization (MRIOV).

As is often the case with new technologies the trend of some saying these are the next great things thus drop everything and adopt them now as they are working and ready for prime time mission critical deployment. Then there are those who say no, stop, do not waste your time on these as they are temporary, they will die and go away anyway. In between, there is reality which takes a bit of balancing the old with the new, look before you leap, do your homework, and do not be scared however have a strategy and a plan on how to achieve it.

Thus is FCoE a temporal or temporary technology? Well, in the scope that all technologies are temporary however it is their temporal timeframe that should be of interest. Thus given that FCoE will probably have at least a ten to fifteen year temporal timeline, I would say in technology terms it has a relative long life for supporting coexistence on the continued road to convergence which appears to be Ethernet.

Industry Trends and Perspectives: Storage Virtualization and Virtual Storage

This is part of an ongoing series of short industry trends and perspectives blog posts briefs.

These short posts compliment other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageioblog.com/reports.

The topic of this post is a trend server virtualization and recent EMC virtual storage announcements.

Virtual storage or storage virtualization has been as a technology and topic around for some time now. Some would argue that storage virtualization is several years old while others would say many decades depending on your view or definition which will vary by preferences, product, vendor, open or closed, hardware, network, software not to mention feature and functionality.

Consequently there are many different views and definitions of storage virtualization some tied to that of product specifications often leading to apples and oranges comparison.

Back in the early to mid 2000s, there was plenty of talk around storage virtualization which then gave way to a relative quiet period before seeing adoption pickup in terms of deployment later in the decade (at least for block based).

More recently there has a been a renewed flurry of storage virtualization activity with many vendors now shipping their latest versions of tools and functionality, EMC announcing VPLEX as well as the file virtualization vendors continuing to try and create a market for their wares (give it time, like block based, it will evolve).

One of the trends around storage virtualization and part of the play on words EMC is using is to change the order of the words. That is where storage virtualization is often aligned with product implementation (e.g. software on an appliance or switch or in a storage system) used primarily for aggregation of heterogeneous storage, with VPLEX EMC is referring to it as virtual storage.

What is interesting here is the play on life beyond consolidation a trend that is also occurring with servers or using virtualization for agility, flexibility and ease of management for upgrades, add, move and changes as opposed to simply pooling of LUNs and underlying storage devices. Stay tuned and watch for more in this space as well as read the blog post below about VPLEX for more on this topic.

Industry Trends and Perspectives: Tape, Disk and Dedupe Coexistence

This is part of an ongoing series of short industry trends and perspectives blog posts briefs.

These short posts compliment other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageioblog.com/reports.

The topic of this post is a trend that I am seeing and hearing about during discussions with IT professionals pertaining to how tape is still alive despite common industry FUD.

Not only is tape still very much alive with recent enhancements including LTO5 with an extended range roadmap, it is also finding new roles. In addition to being deployed in new roles, tape is coexisting and complimenting dedupe or other disk based backup and data protection approaches and vice versa.

Hearing tape is alive in the same sentence as dedupe deployments continuing may sound counter intuitive if you only listen to some vendor pitches.

However if you talk with IT customers particularly those in larger environments or with VARs that provide complete solution offering focus you will hear a different tune than tape is dead and dedupe rules. Tape is still alive however its roll is changing. Watch for more on this and related topics.

That is all for now, hope you find this ongoing series of current and emerging Industry Trends and Perspectives interesting.

Industry Trends and Perspectives: Tiered Hypervisors and Microsoft Hyper-V

Storage I/O trends
This is part of an ongoing series of short industry trends and perspectives blog posts briefs.

These short posts complement other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageioblog.com/reports.

Multiple – Tiered Hypervisors for Server Virtualization

The topic of this post is a trend that I am seeing and hearing about during discussions with IT professionals of the use of two or more server virtualization hypervisors or what is known as tiered Hypervisors.

Server Virtualization Hypervisor Trends

A trends tied to server virtualization that I am seeing more of are that IT organizations are increasingly deploying or using two or more different hypervisors (e.g. Citrix/Xen, Microsoft/Hyper-V, VMware vSphere) in their environment (on separate physical server or blades).

Tiered hypervisors is a concept similar to what many IT organizations already have in terms of different types of servers for various use cases, multiple operating systems as well as several kinds of storage mediums or devices.

What Im seeing is that IT pros are using different hypervisors to meet various cost, management and vendor control goals aligning the applicable technology to the business or application service category.

Tiered Virtualization Hypervisor Management

Of course this brings up the discussion of how to manage multiple hypervisors and thus the real battle is or will be not about hypervisors, rather that of End to End (E2E) management.

A question that I often ask VARs and IT customers if they see Microsoft on the offensive or defensive with Hyper-V vs. VMware and vice versa, that is if VMware is on the defense or offense against Microsoft.

Not surprisingly the VMware and Microsoft faithful will say that the other is clearly on the defensive.

Meanwhile from other people, the feelings are rather mixed with many feeling that Microsoft is increasingly on the offensive with VMware being seen by some as playing a strong defense with a ferocious offense.

Industry Trends and Perspectives: 6GB SAS and DAS are not Dumb A$$ Storage

Blog: Industry Trends and Perspectives: 6GB SAS and DAS are not Dumb A$$ Storage

This is part of an ongoing series of short industry trends and perspectives blog posts briefs.

These short posts compliment other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageioblog.com/reports.

With 6G that increases performance as well as connectivity flexibility, more servers are supporting SAS natively while storage system continue to add support for 3.5" and 2.5" small form factor high performance and large capacity SAS drives. Shared SAS DAS storage systems are being deployed for consolidation attached to two or more servers as well as for clustered solutions.

Another area where shared SAS DAS storage is being deployed is in cloud, scale out NAS and bulk storage environments as a price performance alternative to iSCSI or Fibre Channel solutions.

Keep an eye on these and other trends including converged systems, server, storage and networking management along with associated tools.

Industry Trends and Perspectives Blog Series

This is the first in a series of ongoing short industry trends and perspectives blog post briefs. These short posts compliment other longer posts along with traditional industry trends and perspective white papers, research reports, solution brief content found at www.storageioblog.com/reports.

I often get asked by people what Im seeing or hearing new (aka what is the Buzz).

Sometimes when I tell those who ask about new things or what they have not read or heard about yet, I get interesting as well as varied sometimes even funny reactions. In most cases unless the person does not agree or like the trend, the reaction shifts to one of wanting to know more including what is driving or causing the activity, its impact along with what can be done.

As some are new or emerging they may not yet be being covered in other venues, research, surveys, studies or reports. Thus do not be surprised or alarmed if there is something listed here or in one of the subsequent series post that you have not seen or read elsewhere yet while others may already be familiar. Some are emerging trends perhaps even being short lived while others will have longer legs to evolve.

Some general trends that I am seeing and hearing from IT professionals include:
