7. filename\location XP256 Titan Investigation Performance Rules of Thumb (ROT) Note: The maximum disk performance is derived by taking the performance of a single raid group and dividing it by the number of disks in that raid group. A RAID1 group has 2 disks. A RAID5 group has 4 disks. All measurements were done with OPEN 8 emulation and with 1GB cache in the XP256. Response Times of 25 ms or less were factored in. rot
