Over on the Tivoli Storage Blog, there is an exchange over the concept of a "Storage Hypervisor". This started with fellow IBMer Ron Riffe's blog post [Enabling Private IT for Storage Cloud -- Part I], with a promise to provide parts 2 and 3 in the next few weeks. Here's an excerpt:
Then another IBM blogger, Richard Vining, continued this meme with his post [VMware Data Protection with a Storage Hypervisor]. There are [different meanings for the word "protect"], but Richard's usage relates to protecting against unexpected loss. Here's an excerpt:
At this point, you might scratch your head and ask "Does this Storage Hypervisor exist, or is this just a theoretical exercise?" The answer of course is "Yes, it does exist!" Just like VMware offers vSphere and vCenter, IBM offers block-level disk virtualization through the SAN Volume Controller(SVC) and Storwize V7000 products, with a full management support from Tivoli Storage Productivity Center Standard Edition.
SVC has supported every release of VMware since the 2.5 version. IBM is the leading reseller of VMware, so it makes sense for IBM and VMware development to collaborate and make sure all the products run smoothly together. SVC presents volumes that can be formatted for VMFS file system to hold your VMDK files, accessible via FCP protocol. IBM and VMware have some key synergies:
But unlike tools that work only with VMware, IBM's storage hypervisor works with a variety of server virtualization technologies, including Microsoft Hyper-V, Xen, OracleVM, Linux KVM, PowerVM, z/VM and PR/SM. This is important, as a recent poll on the Hot Aisle blog indicates that [44 percent run 2 or more server hypervisors]!
For a set of best practices combining VMware with SVC, check out this IBM Redpaper titled [VMware Proof of Practice and Performance Guidelines on the SAN Volume Controller].
Join the conversation! The virtual dialogue on this topic will continue in a [live group chat] this Friday, September 23, 2011 from 12 noon to 1pm EDT. Join me and about 20 other top storage bloggers, key industry analysts and IBM Storage subject matter experts to discuss storage hypervisors and get questions answered about improving your private storage environment.

Webcast: How to Diagnose and Cure What Ails Your Storage Infrastructure
Wednesday, March 23, 2011 at 11:00 AM PDT / 11:00 AM Arizona MST / 2:00 PM EDT
Storage is the most poorly utilized infrastructure element -- and the most costly part of hardware budgets -- in most IT shops today. And it’s getting worse. Storage management typically involves nightmarish mash-up of tools for capacity management, performance management and data protection management unique to each array deployed in heterogeneous fabrics. Server and desktop virtualization seem to have made management issues worse, and coming on the heels of changing workloads and data proliferation is the requirement to add data management to the set of responsibilities shouldered by fewer and fewer storage professionals. Forecast for Storage in 2012: more pain as long delayed storage infrastructure refresh becomes mandatory.
In this webcast, fellow blogger Jon Toigo, CEO of Toigo Partners International, of [DrunkenData] fame, and I will take turns assessing the challenges and suggesting real-world solutions to the many issues that confound storage efficiency in contemporary IT. Integrating real world case studies and technology insights, our storage experts will deliver a must see webcast that sets down a strategy for fixing storage...before it fixes you.
Don't miss this event, unless you like the stress of knowing that your next disaster may be a data disaster.
Register for this webcast to come hear me and Jon Toigo talk!
Continuing my coverage of the Data Center Conference, Dec 1-4, 2009 here in Las Vegas, this post focused on data protection strategies.
Two analysts co-presented this session which provided an overview of various data protection techniques. A quick survey of the audience found that 27 percent have only a single data center, 13 percent have load sharing of their mission critical applications across multiple data centers, and the rest use a failover approach to either development/test resources, standby resources or an outsourced facility.
There are basically five ways to replicate data to secondary locations:
A question came up about the confusion between "Disaster Recovery Tiers" and Uptime Institute's "Data Center Facilities Tiers". I agree this is confusing. Many clients call their most mission critical applications as Tier 1, less critical as Tier 2, and least critical as Tier 3. In 1983, IBM User Group GUIDE came up with "Business Continuity Tiers" where Tier 1 was the slowest recovery from manual tape, and Tier 7 was the fastest recovery with a completely automated site, network, server and storage failover. However, for Data Center facility tiers, Uptime has the simplest least available (99.3 percent uptime) data center as Tier 1, and the most advanced, redundant, highest available (99.995 percent) data center as Tier 4. This just goes to show that when one person starts using "Tier 1" or "Tier 4" terminology, it can be misinterpreted by others.
