EMC makes virtual provisioning free

Beth Pariseau Beth Pariseau Profile: Beth Pariseau

Call it a Lutheran Reformation for the 21st century. This time, instead of 95 theses nailed to a church door to challenge the Catholic Church, EMC customer and blogger Martin Glassborow posted one thesis on his blog to challenge EMC on the cost of virtual provisioning, also known as thin provisioning.

Even as storage vendors have been touting the cost savings of thin provisioning, it has cost customers extra to deploy the feature. Wrote Glassborow:

HDS and EMC are both extremely guilty in this regard, both Virtual Provisioning and Dynamic Provisioning cost me extra as an end-user to license. But this is the technology upon which all future block-based storage arrays will be built. If you guys want to improve the TCO and show that you are serious about reducing the complexity to manage your arrays, you will license for free. You will encourage the end-user to break free from the shackles of complexity and you will improve the image of Tier-1 storage in the enterprise.

(HDS might have some quibble with this – another blogger, storage consultant Chris M. Evans, points out that HDS’ Switch It On promotion offers free UVM, Dynamic Provisioning (first 10TB only) and Tiered Storage Manager on existing USP-V deployments. Evans also notes HDS’s promo is for existing as well as new deployments; EMC told me today existing Symm deployments will also be eligible, but there appears to be some confusion about that.)

Glassborow’s wish was granted. In response, EMC blogger Barry Burke, also chief strategy officer for Symmetrix, wrote:

In his post, Martin insists that the current pricing strategies for thin provisioning from both HDS and EMC are a disincentive to the adoption of the otherwise compelling feature that makes enterprise arrays easier and more cost-effective to manage and deploy.

These very conversations have been going on within the walls of EMC, and it has been decided that Virtual Provisioning will in fact be included at no charge and with no capacity limitations for all Symmetrix V-Max and DMX 4 orders beginning this quarter.  As a result, all Symmetrix V-Max and DMX 4 customers will be able to leverage the speed and ease of storage provisioning, improved capacity utilization and the inherent benefits of wide striping afforded by Virtual Provisioning, all at no extra charge.

We’ll see if others follow suit.

We shall, and if it happens soon, call me cynical, but I will wonder about the timing of this decision on EMC’s part. As Burke notes, this isn’t the first time Glassborow has come knocking with his pricing protest (though I think he deserves credit for his good points and persistence). Should we be anticipating another vendor to be heard from when it comes to free thin provisioning?

And what about Clariion? EMC added thin provisioning to the CX4 last year, but the free thin provisioning is only available for Symmetrix so far.
