There are differences of opinions in our organization regarding this issue. From the DBA Standpoint we strive to implement the correct solution using RAID1 or VRAID1 for protection of the data as well as performance. However, the Technical Support personnel are insisting that VRAID5 should be used because ?It is a SAN and the performance benefits are the same for VRAID5 as VRAID1 without incurring the cost of disk drives?.

All the documentation I can find seem to indicate that the methodology of ?how? RAID levels act are virtually the same whether it is on a local DAS or on a SAN. In other words RAID1 and VRAID1 function the same way and offer the same protection and performance. The same would hold true with RAID5 and VRAID5.

Thanks in advance.
