We are looking at an inexpensive NAS solution for VM backups. Our VMs run on our SAN so we don't need something to run VMs, or anything fast, just something to easily backup VMs to.
I assume mostly what I need to look at is connectivity to our ESXi hosts or the SAN. I think I am seeing that some lower priced NAS either don't have iSCSI ports or they don't have the ability to be seen by more than one ESXi host at once. SPC-3 capability?
We have an HA cluster of three esxi hosts connected via fiber to our SAN. What is the best way to be able to backup to a NAS from all three hosts? Can the nas connect to the SAN? Do I need to just put it on the network and create an NFS share on it? What is the best way?
One I was looking at was the Buffalo TeraStation 3. 12TB. It's about $1800 but doesn't have iscsi. The ones that does can only be seen by one host at a time. Probably won't work then.
thanks for any advice.
