Hi,

 

I could be wrong but from my recollection the 2220 would have 15K disks while the 2240-2 would only be 10K.  The last price list I saw you could buy a 2220HA Complete Bundle with 12 x 600 plus a DS4243 with 12x600 for less than a 2240-2HA with 24x450… and you would have 24 15K disks instead of 24 10K.

 

If you have the power, cooling and rack space I would personally go with the 2220 plus DS4243 so long as you don’t expect the system to grow significantly (and don’t need FC or 10GbE options).

 

Kind regards

Steve

 

 

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
