Queue Depth Parameters Table Table 8. Queue Depth Parameters Type Parameter Name Default Value SCSI Read/write time-out 30 Queue depth 1 Queue type None Fibre Channel Read/write time-out 30 Queue depth Before 52-38-xx Required Value for Disk Array 60 2 (For LUSE devices, use 2 for each LUN. For example, if one LUSE device contains 8 LUNs, use 2 × 8 = 16 for the queue depth.) Simple 60 Use 2 if exclusively OPEN-K/3/8/9/E volumes are mapped to the SCSI/FC port. Use 8 if exclusively LUSE volumes are mapped to the SCSI/FC port. Use 2 if an intermix of LUSE and OPEN-K/3/8/9/E volumes is mapped to the SCSI/FC port. Queue type 52-40-xx to 52-44-xx 52-45-xx or later None Use 8 if an intermix of LUSE and OPEN-K/3/8/9/E volumes is mapped for dummy LU (I-7135-Emu). Number of volumes × queue-depth ≤ 256 and queue-depth ≤ 8 Number of volumes × queue-depth ≤ 256 and queue-depth ≤ 32 Simple 50 hp surestore disk array xp operating system configuration guide: SGI IRIX
