Breaking the Storage Silo: Virtualization

Photo via Don Jennings (click to see his SNW write-up)

Last week, Storage Networking World (SNW), the “World’s Largest Storage, Data Center and IT Infrastructure Conference” brought together a couple thousand people to hear the latest in storage optimization and innovation. With the big trends of virtualization, convergence and cloud computing, it is without a doubt that the role of the storage administrator is evolving. While streamlining roles can help improve operational expenses, when it comes to storage, data availability and data integrity must be maintained. There are a number of solutions that are looking to transform and potentially chip away at the traditional storage administrator’s role.

Long Distance Live vMotion Storage Gems from VMworld 2009 Portend the Future for EMC?

At VMworld 2009 in San Francisco, EMC, VMware, and Cisco presented a “super” session (TA-3105) entitled “Long Distance Live vMotion. Cisco published a white paper about it and Chad Sakac of EMC discussed it extensively in his blog entry. A video of this standing-room-only session is available at Blip TV link (had trouble playing link from Chad’s blog entry; doesn’t work with Firefox). VMware also reversed course and announced that it was now supporting this configuration.

EMC announces multiple Clariion enhancements virtualization, replication and drive spin down.

EMC announced today several enhancements to their Clariion product line ranging from optimizing the Clariion CX4 virtualized experience, to increased connectivity and scale in the virtual environment to the introduction of an energy efficient spin down feature.

This announcement details a number of innovations that raises the competitive bar for EMC’s midrange competitors particularly in the virtualized storage space which will no doubt inject energy into this platform. Guess the close relationship with VMware does have tangible advantages. I appreciated the toggling feature of RecoverPoint as innovative and offers a neat solution to demand spikes.

It’s not working…it’s networking!

One of the many things I learned from my sales mentor Jeffrey Gitomer is that if your industry is having an event and there will be more than 100 high profile butts in the seats, then your butt better be there too with an elevator pitch, a stack of business cards and some great ideas– everybody loves ideas right?

Well, last December I got a call from Greg Duplessie explaining to me that he had this idea for a networking event called, get this – The Business Development Networking Event. Needless to say, I didn’t have to ask what the purpose of the conference was if you know what I mean.

3PAR shows the human side of business.

In today’s uncomfortable economic climate it is a welcome relief to read that folks still have the inclination to extend a helping hand. Red Nose Day is a nationwide fundraising event organized by Comic Relief every two years in the UK. This year the event raised over $80M which will go a long way to help many disadvantaged folks.

Details on EMC’s V-Max Virtual LUN Technology Enhancements

Virtual LUN Technology

The Symmetrix V-Max storage array enhances the Virtual LUN technology offered by DMX storage arrays. The Virtual LUN technology on the V-Max array can now perform transparent, nondisruptive data mobility between storage tiers for standard Symmetrix devices. This technology is based on the Enginuity Virtual RAID Architecture and requires Enginuity code level 5874. Virtual LUN migration provides users the ability to move data between high-performance drives and high capacity drives. This new functionality is used to either change RAID protection types, move between physical disk groups, or both. It supports the migration of regular devices or meta-volumes, and can utilize configured or unconfigured disk space as the target. When the migration is performed to configured space, the target of the invocation cannot be assigned to a host. Migration is facilitated by the creation and movement of Symmetrix devices. Upon completion of the migration, the original devices are deleted and the space is freed.

Does EMC’s New Symmetrix V-Max Deserve a “V”?

CEO Joe Tucci touts V-Max as haVing been “purpose built for Virtual datacenters”, but how does it differ from Symmetrix DMX with respect to Virtualization?

 

The word “Virtual” means to make something appear to be real when it is not such has a reflection in a mirror. In the data storage world, Virtualization makes the location and size of LUNs/blocks/files appear to the serVer to be constant when they are not.

 

Let’s start with the DMX’s Virtualization features:

 

  • RAID – 1st layer of Virtualization aboVe a JBOD
  • Virtual/Thin proVisioning

V-Maxed out? Take a Deep Breath and Sharpen the Pencils.

For weeks the brain trust at Wikibon and I have been dissecting EMC’s V-Max announcement and we still have  a ways to go. Our technical guys want to go even deeper and we need to put together a good roadmap to help clients go from where they are today to this new vision of the virtual data center– if that’s where they really want to go.

Why Wouldn’t Customers Want to Migrate?

Getting the “Tweety” Bug @ SNW

Spring 2009 Storage Networking World is now history. As expected the crowds were down a bit with the vendor participation down significantly but according to the SNW folks, end user attendees were at 92% when compared to last year, not too bad considering current economic realities.

 

Eyes are now on SNW Fall to see how well the event can rebound, or not.

Why aren’t more VMware storage arrays virtualized?

Yesterday, the Wikibon community heard from Cal State U East Bay’s Rich Avila. He, like other guests on Wikibon, including BT’s Michael Crader, have cited the benefits of combining server and storage virtualization. Yet numerous customers we speak with don’t virtualize storage arrays under VMware.

Industry data from IDC and Forrester over the past few years clearly shows EMC dominates in virtualized server environments as the backend storage platform of choice. The data ranges from 40% to close to 50% market share. Clearly these EMC arrays are not sitting behind Invista so one can only assume the capacity of these arrays is not virtualized. Folks like 3PAR of course would say that this is a missed opportunity– once you try a fully virtualized platform under VMware you’ll see the advantages and won’t go back.
