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.

Whether we like it or not, RFPs (Request For Proposal) are a fact of life for vendors.
It usually works like this: A customer has a legitimate need for something. They decide (for whatever reason) to get bids from different vendors. They then craft an RFP document that is either:
- Carefully written, with the best intentions, so that they get the most detailed proposal possible given their requirements, or
- Carefully tailored by them and the help of their preferred vendor to box out the other vendors.

<Edited to add some more information on how SPC-1 works since there was some confusion based on the comments received>
We’ve been busy at NetApp… busy perfecting the industry’s only scale-out unified platform, among other things.
We’ve already released ONTAP 8.1, which, in Cluster-Mode, allows 24 nodes (each with up to 8TB cache) for NAS workloads, and 4 nodes for block workloads (FC and iSCSI).

<Article updated with more accurate calculation>
There are some impressive new scores at storageperformance.org, with the usual crazy configurations of thousands of drives etc.
When looking at $/IOP, make sure you are comparing list price (look at the full disclosure report, that has all the details for each config).
Otherwise, you could get the wrong $/IOP since some vendors have list prices, others show heavy discounting.
