Response times at the LUN is what the user sees, not the disks. Also, be careful with response times - it's a calculated value based on queue length and IOPS. If IOPS are low (under about 100 IOPS), then response times can be very high - you can ignore these.  glen
When I view the Lun Read size KB it is a lot smaller than the disk Read size KB. Even when you combine all the Luns within the Raid group the Read size KB does not come close too what the Read size KB is on disk  e.g 4 Luns all Read size 2KB  yet the disk read size can be as high as 229 KB ?  any ideas
