It's really fun and amazing to see this "record break" on theses technologies.

BTW, your link for PDF on http://www.vmware.com/files/pdf/techpaper/1M-iops-perf-vsphere5.pdf is broken

It only required 960 disks in a VMAX to do this? Fusion-io can do 1,000,000 IOPS on a single card... in a single server. :)

Waiting for the RAMSAN post about welcome. You know it's coming :). lol.

Good Job Chad. Awesome stuff once again. Bone-crushing performance. Was PowerPath / VE used? Would it have incurred more latency? Would it have helped the numbers? Just wondering :).

Tore

How can one view the usage of backend CPU on a VMAX? I suspect we have some problems here on our systems.

Note - the link above for the study on VMware's site is broken... use the following link instead:

@Tore - it's pretty easy. you can use Symmetrix Performance Analyzer. If you're stuck, please open a support case!!!

@Tom - thanks - link fixed.

@Chappy - you bet - and sure enough, right before you, FusionIO piped up :-) Hey, we're all predictable :-)

@Simon - thanks for the comment. The "single server" thing is the archilles heel in some use cases, isn't it. This is why I think any vendor who says flash in one way, in one place is missing it. when it comes to simplest path to pure IOps, and low latency, there is no substitute for host-based flash (commodity the intel way, commodity the OCZ REVO way, the Fusion IO way, and the EMC Project lightning way).

The downside is that if the info is "captive" to the host, you lose a lot. You lose a lot of VMware function, you lose common models for data protection. And, of course, in the real world, workloads tend to be all over the map in terms of performance needs - and even vary over time. These are the use cases where shared flash models make a lot of sense. Thanks for the comment!

Hyper-V did 1 million IOPS using a single VM though!
