Hi
Basically a HP P2000 MSA G3 or a Dell PowerVault MD3xxx would be sufficient. We got a lot of customer who are happy with their entry SAN solution. Both can be extended via additional SAS shelf and both can handle SATA/SAS/SSDs. For some more high availability you could also check out HPs StoreVirtual platform (former LeftHand) or a small DataCore SANSymphony-V setup (like two std. servers with local storage). Maybe a Nimble array would also fit for your needs.
HP could be cool if you consider combining it with Veeam for “snapshot based” backups. NetApp’s solutions like SMVI also offers some cool features. So you probably want to take a backup & restore / DR concept into account before choosing a storage array.
1 Gbe will be sufficient for the mentioned workload.
Regards
Patrick
