Thanks for that, the link explained it a bit better. we have the database and logs on separate raid 10 luns the rest are on raid 5 (I think)
vkf,
when you say use 2 different controllers. use 2 different types or just 2 separate controllers?
After reading Vervoot's link I was planning on setting it up like this
O/S on 0:0 PVSCSI
Database on 1:0 PVSCSI
Logs on 2:0 PVSCSI
Temp on 3:0 PVSCSI
SysDB on 3:1 PVSCSI
PageFile on 3:2 PVSCSI
