HP SAN for DR environment - MSA or EVA ?

Hi Everyone,

I'm looking for a shared storage for my ESX servers in the DR datacenter, most of the transaction will be random I/O eg. Database,
which Storage / SAN should I choose that is compatible with HP DL 380 servers ?

Thanks.

i personally recommend Netapp

Ultra speed , deduplication, raid DP(fault tolerance) , etc.

@Randy: yes I do need replication if possible.
Deffo look at the LeftHand then - or NetApp etc but these come at a cost!

ok so based on your suggestion then the rating is like (from slow to fast performance):

MSA
Lefthand
EVA
NetApp

@Andrei and Andy: Yes I'll browse around in google for that and call my HP dealer.

The reason I'm asking is for writing down proposal so that i can get approval from the management first.
depends on what you're doing - EVA versus NetApp is a subjective thing depending on all sorts of other factors

ah yes,

at the moment I have 3-4 ESX servers with approximately 80 VMs running Databases and some of them critical tier-1 apps like Exchange and AD in the DR datacenter, in my current production I use EMC Clariion CX-500 Fibre Channel

so for the DR it seem that iSCSI should be working fine. I don't know if this is possible that's why I ask here.
is email a citricial service? Ask Management, they may have a different view?

do you need all 80 VMs in a DR situation?
and if you want to make it easy for yourself, you don't mention where the other datacentre is, and how it's connected, but if you were to put a baby EMC Clariion in it, you could replciate LUNs to the site for DR.

ah ok, hence the name
MSA --> Medium Small Array
EVA --> Enterprise Versatile Array

perhaps ?
Hi

MSA = Modular Storage Array
EVA = Enterprise Virtual Array

Interestingly the published specs for the EVA4400 and P2000 MSA show the P2000 as being faster, but there again there's 149 disks on the MSA and only 96 on the EVA.

Performance data from

yes, i guess MSA is good for virtualizing many VMs at once since it got many spindles.
thanks Andy.

I'll create another thread after gathering some more info myself about the kind of SAN that I'm looking for.
It's only got more disks because the EVA4400 is the entry level model, the 6400 and 8400 take more but aren't customer installable, reseller is meant to do it.
