EMC's VMware unit is taking on HP with a Virtual Storage Appliance (VSA), building a small and medium business mini-SAN from servers' direct-attached storage.

RAID 5 not RAID 10
The internal RAID configuration of VSA is RAID 5 not RAID 10, and of course RAID 1 between nodes. It is still a large amount of data for a virtual storage appliance versus a real SAN array.
Customers should consider it.
