Re: ewan.to - Benchmarking storage

Ewan, I sympathise wtith your situation. SPC is aimed more at whats the maximum bandwidth while keeping within certain response times.

If you find the ESS still acceptable in performance, you could always front it with an SVC and investigate some mid-range products - the extra cache boost from SVC will esentially boost the performance of modern mid-range controllers - things have moved on a lot since ESS, and the mid-range DS4800 range maybe enough for your needs.

With SVC you get the FlashCopy as required, and a platform for future SVC code enhancements (lot of good and interesting things planned for next year)

The biggest benefit right now would be the online migration path off of the ESS at a time that suits you (after a small bit of downtime to remap the ESS luns through SVC.

I'm sure your IBM sales rep / business partner can provide plenty of help as required.

When SVC is in the mix, we are quite happy to help diagnose from the host to the SAN through SVC and to the storage. The major players in the industry have signed up to a common support agreement when it comes to SANs, not only will we (IBM) help diagnose, but drive through to any vendor that is claiming it aint their problem. I think you might find another TLA corporation does the most finger pointing, and doesn't play ball when things haven't gone their way. Each can read their own into this...

Well given that the DMX is slower than DS8000 then what does that say? (unless you have some independent benchmark that shows otherwise you'd like to share?)

You could put SVC nodes infront of anything in the open systems world, and get thin provisioning for no extra charge - still be cheaper than paying for it on DMX or USP.
