I'm glad to see large block workloads are being improved (I was this customer: http://virtualgeek.typepad.com/virtual_geek/2010/02/solving-a-weird-slow-performance-cloning-issue.html)

To be fair though, #5 isn't a new innovation in storage land. Compellent has been doing it for a while now. They call it "Live Volume".

"EMC now has VAAI support in the midrange and the high end enterprise arrays. I **think** this makes us the only vendor with VAAI support across the midrange and the Enterprise storage market".

That would be incorrect. NetApp has VAAI support in Data Ontap 8.0.1 for FC, FCoE and iSCSI datastores. Since all entry level, midrange and enterprise storage controllers all run the same Ontap, that means VAAI support throughout - but you already knew this ;-)

Ian, I disagree.

It's not my definition, but in general the "Enterprise" array segment is characterized by arrays that have many processors, large shared, global caches, and support a very broad host-attach profile (including mainframes). In this category, you've got things like EMC VMAX, HDS VSP, IBM DS8000.

In my experience, when a customer's requirements put them into that class of platform, generally we don't see them looking for VNX, and we don't generally compete with NetApp. Sometimes they put Celerra Gateways, or v-Series NetApp platforms in FRONT of those arrays to support NAS use, but that's a different thing altogether.

That's not to say that the the larger FAS6200/6000 (and other FAS arrays) don't serve enterprises, just like the VNX series does (and their smaller brethren).

But - those segments, and the architectures that support them are markedly different. I'm not making a qualitative judgement about good/bad - that's up to customers. Those customers pick those "Enterprise" (I wish there was a better word) architectures for many reasons.

Does that make sense?

I'm curious - do you find many customers transitioning to 8.0.1 in 7-mode (or cluster mode for that matter?)
