SCSI addressing A SCSI adapter supports up to 16 devices, including itself. Each
device has its own unique SCSI address. The SCSI address of a
device dictates the device’s priority when arbitrating for the
SCSI bus. SCSI address “7” has the highest priority. The next
highest priority address is “6” followed by 5, 4, 3, 2, 1, 0, 15, 14,
13, 12, 11, 10, 9, 8, with “8” being the lowest priority address.
The narrow SCSI adapter is factory set to address 7. A narrow
SCSI adapter supports up to eight devices, including itself. SCSI
address “7” has the highest priority followed by 6, 5, 4, 3, 2, 1,
and 0.
SCSI bus The means of transferring SCSI data between SCSI devices. It is
an 8-bit or 16-bit bus that supports up to eight or sixteen devices
(including itself), in any mix of initiators and targets, with the
limitation that at least one initiator and one target must be
present.
SCSI device A single unit on the SCSI bus, identifiable by a unique SCSI
address. A SCSI device can act as an initiator or target. For
SCSI-3, each SCSI device supports up to sixteen LUNs.
SCSI port An opening at the back of the TC2201E providing connection
between the SCSI adapter and the SCSI bus.
SCSI status A menu name used to show the number of SCSI devices on the
bus.
synch and steering layer A function of iSCSI Fixed Interval Markers (FIMs) used for
synchronization and steering of iSCSI Protocol Data Units
(PDUs) especially in regards to high-speed iSCSI
implementations.
