I am planning to install a SAN with 14 15K SCSI disks. This configuration will be used by multiple servers. So far it will be 2 dedicated SQL servers and 1 dedicated application server. I have planned to use this RAID configuration: RAID0: 10 disks with RAID 10, for random read/write operations. SQL data and OS devices. RAID1: 4 disks with RAID 10, for sequential read/write operations. SQL TRN logs and some logs from the applications servers. All servers will use the same disk configuration. Is it reccomended to use the same disk configuration on all servers, or should I create dedicated RAID devices for each server?
