In-band SCSI
What is it and why do you need it?
These days more and more external devices require communication
with the host computer for device monitoring and administration. This
is usually done through RS-232C ports.
Acer now offers an alternative means of communication for its RAID
controllers—In-band SCSI. The traditional way for SCSI controllers to
communicate with the host computer has been via software (such as
the Acer RAID Manager ) using an RS-232C connection. With In-band
SCSI, integrators have more flexibility. They may use RS-232C or the
existing SCSI cable instead.
How does it use the SCSI cable? In-band SCSI technology translates
the original commands into standard SCSI commands. These SCSI
commands are then sent to and received from the SCSI raid
controller.
The Acer RAID Manager
can administrate the RAID
controller just as it could before via RS-232C. (Note: It is assumed
that users of In-band SCSI possess the following: a third-party SCSI
adapter and a channel on their Acer RAID controller that can be
designated as a host channel.) Both of these are required for In-band
SCSI communication between the host and the RAID controller. )
