I am looking for some input on Raid Controller selection. I am building an iSCSI SAN for a Hyper-V 2012 Cluster. The SAN OS will be Open-E DSS7 and it will host 20+ VMs.
We will be using a Supermicro case with 16x - 24x bays with built in SAS Expander. We will start with 2 sets of Raid10 with 4x 2TB Seagate Constellation although one of the arrays may end up as RAID5 or 6
I was looking at the LSI 9271-8ICC, which comes with CacheCade. Provantage has the card for $750. Frankly I would like to try the CacheCade but I don't know how it will work in an application with as diverse loads at a SAN for VMs. Cost is always a factor since I am still building the rest of the cluster as well. I thought of using 2x 9260s without CacheCade but it seems better to put my money into a single more capable card.
I am wondering if there are less expensive OEM models or other configuration I should consider.
Thoughts or suggestions are welcome.
