Hi all,

I’ve a startup project that will expect a very simple Hyper-V 2012 iSCSI cluster. Competitor is an EqualLogic appliance 24x300 10k SAS HDs.

There’s a very interesting promo in these days offering a 2220 12x900 SAS at very competitive price vs a 2240-2 24x450 SAS so I was evaluating the 2220.

But I’m concerned about performances. The two server nodes will be “only” 32 GB RAM/2 CPU Xeon 8C so I can presume that the number of VM servers will be no more that 7-8

I’ve lab data from NetApp that state, at lab conditions, that for short random ops with iSCSI the 2220 can do roughy 10k IOPS vs the 30k of the 2240-2, for short write they are quite similar (40k IOPS).

For large ops the 2240-2’s performances are very higher that 2220.

In addition to this I’ve also considered that the 2220 will have ONLY 6 mechanics for each controller while the 2240 will have 12 each…

What do you think about this little cluster? Can I trust in 2220?

Regards
