Just set one of these up today, an ESX box running v.4, tied to a DroboPro with eight 1.5TB drives, giving 8TB of space with the ability to lose 2 drives before data loss. All over iSCSI, and I can have up to four ESX boxes on the same VLAN, sharing that Drobo, while also being able to do VMotion between them. Sweet!!
Configuration was damn simple, especially compared to our needlessly complicated and overpriced Netapp. For less than $3000, this is one helluva storage system.
Holy balls. Is this a home setup? Want!
