20tb Usable Synchronous Storage Cluster?

[hutchingsp]

I'm planning our imminent storage/server refresh.

Right now we have P4000 split across 2 sites with 10GbE and a third witness site on 1GbE.

Our IOPS is very low (< 2000 @ 95th percentile).

My current plan is to spec up a pair of ML350's each with 16x3tb nearline SAS drives in RAID10 and a couple of SSDs.

I then plan on using HP SmartCache on the SmartArray to make the SSDs available as disk cache.

I then plan on running 2x VSA on each box (I need 2 to get the 20tb of capacity that I require).

The Storage Network would be 10GbE with 1GbE as standby adaptor.

Thoughts?

Bad idea then?

It'll be faster.

You'd probably get more input if you posted this in the storage forums

Fair point. Mods feel free to close and I'll repost.
