My organisation is going to invest in either RedHat virtualization with KVM or VMware ESX. Some of our work involves disk intensive bio-informatics stuff such as BLAST, which we have found to mostly be bottle-necked by the disk rather than the CPU.
I know little about network attached storage, SAN, iSCSI etc., but would appreciate some pointers on which storage technology might be worth focussing on. It seems to me that the fastest solution would be locally attached solid state storage, but then we can't have the advantages of VM migrations for fail-over and load balancing.
What storage solution, for about $6-8k, should we be considering?
