(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.)
None Simple

Before 52-38-xx 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.
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
52-40-xx to
queue-depth ≤ 8
52-44-xx
Number of volumes × queue-depth ≤ 256 and
52-45-xx or later
queue-depth ≤ 32
