1. Device model number
2. Device storage capacity
3. User-assigned SCSI LUN
4. User-assigned SCSI identification number (target ID)
5. User-assigned array controller channel number—the
array controller port or SCSI bus number
6. SCSI bus device width:
N — an 8-bit device (narrow)
W — a 16-bit device (wide)
7. StorageWorks shelf type (wide or narrow)
compatibility:
N — device is 8-bit shelf compatible (narrow)
W — device is 16-bit shelf compatible (wide)
N/W — device is 8- and 16-bit shelf compatible
8. Bus speed expressed in megabits per second (Mb/s):
S — Slow device. For example: S5 = 5 Mb/s
F — Fast device. For example: F10 = 10 Mb/s or F20
= 20 Mb/s
9. Maximum rate at which this device transfers
data—expressed in megabytes per second (MB/s)
