Storage Nation

In my series on data center transformation I started with Server transformation and the closer integration of server and storage virtualization through the use of VAAI or vStorage APIs for storage arrays. These APIs were introduced at VMworld in 2008 when VMware announced their vStorage initiatives. When VMware released these APIs on July 13, 2010, Hitachi jointly released support for these APIs on our AMS 2000 storage arrays . A lot of effort went into this integration as it is a massive technology enhancement for the transformation of the data center. The testing that we have done with Hitachi Dynamic Provisioning volumes on an AMS 2300 with VAAI has shown the following results: Full copy – 18% performance improvement (speed to copy VM’s) Write same – 85% performance improvement (speed to clone VM’s) Hardware Assisted Locking – 25% to 35% performance improvement including the removal of SCSI reserves (powering on 1400 VM’s on 4 x Servers simultaneously) See what VMware CTO Steve Herrod says about these enhancements in his executive blog.

This is the third part in my series on data center transformations. My last post was on server transformation and the impact of virtual servers on the data center. In this post I will address the impact of storage transformation on the data center. Data is at the core of the Data center Data is at the core of the data center, and any effort to transform the data center must involve the movement, provisioning, access, and protection of data which is provided by storage systems

I've been going slightly nuts since yesterday after Cisco announced the CIUS.  It looks like the perfect tablet for the sorts of things I really want a personal screen device for – communicating with other people.  This review by Erik Parker of InfoWorld is a pretty good read and it summarizes key advantages and disadvantages of CIUS.  If it can make the technology of video conferencing transparent to end users, it will be a big deal.  But the hidden story to this is that Cisco is also making a play to get into the corporate desktop/laptop business with the CIUS.  The idea that companies could deploy these with VDI is definitely part of Cisco's grand plan for world domination . Whether or not the CIUS could replace laptop or desktop computers remains to be seen, but there are reasons to think they could eventually if the stars align.  The arguments for VDI are strong, but there are still a lot of hurdles to overcome, such as back end storage performance to support boot storms . By the way, people looking at large VDI implementations might want to look at 3PAR's wide striping storage systems to get the sort of affordable IOPS needed to support large VDI environments. My previous post illustrates our design for massive throughput, which supports a huge number of IOPS without needing SSDs or requiring storage administrators to create special disk pools to isolate the VDI workload from other applications running in the same storage array.

Steve Taylor, one of our SEs, created an animation that shows the multiple layers of virtualization that create the natively wide-striped data layout on a 3PAR storage server.  I think it's the coolest thing I'd seen since joining the company that quickly summarizes the multiple layers of virtualization in a 3PAR array.  All the functions shown are automatically done for the customer with minimal administrative effort.

There is an increasing interest in storage virtualization as seen an the increasing number of articles and blog posts on storage virtualization. In the last few days Rick Vanover posted a very balanced overview of storage virtualization for Datamation where he reviewed some of the many options.   Carol Sliwa posted a Storage Pro Guide to block-based storage virtualization for SearchStorage which cited some use cases. One of the use cases was the City of Coquitlan (Canada) who is a 2010 Computerworld Honors Laureate award winners in IDG’s Computerworld Honors Program and a customer of Hitachi.

A new survey by Intercall shows that 48 percent of americans who use technology in their everyday jobs say that they are now required to do more work with fewer resources due to the current economic climate.

Here's a video that TechTarget produced for us with one of our customers, Priceline.com . Here are a few highlights from the video: Priceline.com was one of the first e-commerce players to adopt virtualization.  That may account for why the company's IT organization is known for for it's high availability and ability to adapt quickly to changes in the market.  Given the fact that their business has a broad value-based appeal, their IT organization works very hard to get the best rate of return for their capital expenditures. 3PAR storage allowed them to increase their storage capacity over 400% over the last four years while reducing the administrative load required to manage it all. Ron Rose, ex-CIO at Priceline (now on the Sr

Since 1988, the Computerworld Honors Program has been recognizing and documenting the achievements of men, women, organizations and instututions around the world whose visionary use of information technology promotes positive social, economic and educational change. We are pleased to announce that five Hitachi Data Systems customers have been selected as the 2010 Computerworld Honors Laureate award winners by IDG’s Computerworld Honors Program. These Hitachi Data Systems customers will be recognized during the 22nd Annual Laureates Medal Ceremony & Gala Awards Evening on June 7, 2010 at the Andrew W. Mellon Auditorium in Washington, D.C.

Full Time Employee (FTE) per TB used to be a measure of productivity for storage managers. Some people still use that metric today. I submit that FTE per TB is no longer relevant today. For the last 10 years the mantra for IT has been “do more with less”

A Computerworld article by Bernard Golden highlights an IDC report that says that the “digital Universe” will grow by 1.2 zeta bytes or 1.2 million peta bytes in 2010. One of the biggest issues with this increasing data growth is the ability to search for that particular piece of data that you need.
