It was with interest that I watched the launch of EMC’s VNX refresh. The updated boxes got some long-awaited features, EMC talked a lot about how some pretty severe single-threaded bottlenecks were removed, more CPU and memory was put in, and there was much rejoicing.
Not really trying to pick on the new boxes (that will be in a future post, relax :)), but what I thought was interesting was that the code that makes most of the new features a possibility cannot be loaded on current-gen VNX boxes (not even the biggest, the 7500, which has plenty of CPU and RAM juice even compared to the next gen boxes).
Software-defined storage indeed.

It was with interest that I watched some of EMC’s announcements during EMC World. Partly due to competitor awareness, and partly due to being an irrepressible nerd, hoping for something really cool.
BTW: Thanks to Mark Kulacz for assisting with the proof points. Mark, as much as it pains me to admit so, is quite possibly an even bigger nerd than I am.
So… EMC did deliver something. A demo of the possible successor to VNX (VNX2?), unavailable as of this writing (indeed, a lot of fuss was made about it being lab only etc).

Lately, when competing with VNX, I see EMC using several points to prove they’re superior (or at least not deficient).
I’d already written this article a while back, and today I want to explore a few aspects in more depth since my BS pain threshold is getting pretty low. The topics discussed:
- VNX space efficiency
- LUNs can be served by either controller for “load balancing”
- Claims that autotiering helps most workloads
- Claims that storage pools are easier
- Thin provisioning performance (this one’s interesting)
- The new VNX snapshots
References to actual EMC documentation will be used. Otherwise I’d also be no better than a marketing droid.

Just as NetApp dominated the older version of the SPEC SFS97_R1 NFS benchmark back in May of 2006 (and was unsurpassed in that benchmark with 1 million SFS operations per second), the time has come to once again dominate the current version, SPEC SFS2008 NFS.
Recently we have been focusing on benchmarking realistic configurations that people might actually put in their datacenters, instead of lab queens with unusable configs focused on achieving the highest result regardless of cost.

Most are familiar with Hanlon’s Razor:
Never attribute to malice that which is adequately explained by stupidity.
A variation of that is:
Never attribute to malice that which is adequately explained by stupidity, but don’t rule out malice.
