A four-way cluster is attached to two fabrics. Each member has two HBAs connected to each
fabric. Each fabric has two array connections. SCSI Queue Depth for HBAs = 8 and Storage
devices = 256 per port. Each cluster member is a primary for one application. All LUNs appear on
all storage ports with workload equally distributed across all. Each host has two dedicated HBAs
for tape that can each see four independent LTO II tape drives. All files are large and involve
sequential I/O. Performance reporting shows a large read pending at the host during multithreaded backup. What is the maximum value you should set for SCSI Queue Depth?
