I am going to be implmenting a VMware vSphere 4 setup in our company. At first I had the plans of using a Netgear ReadyNAS business applicance for VM storage via iSCSI. But as I was looking around for parts for my VMware server (license 2/3) I was thinking of a different approach.
I was thinking what if I just loaded 6 WD Scorpio Black 500GB SATA drives into the server and ran a DAS setup rather than investing in a NAS.
The reason I was thinking we need more space than anything. We are most likely never going go beyond 1 VMware server because we are so small (my server does not count) We only will be running 4 VMs max. Also we do not have licenses for the VMware HA components.
What would be downsides to have the storage with the VM server in small setup like this?
Backups would be handled by the vCenter server which is a separate server. So getting to the storage in either regard is not a problem.
