ASUS GUI RAID Manager: Installation 2.3 In-band SCSI What is it and what is it used for? 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. An alternative means of communication is now available for SCSIto-SCSI RAID controllers-In-band SCSI. The traditional way for SCSI controllers to communicate with the host computer has been via software (such as the GUI 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 is it able to 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 GUI 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 thirdparty SCSI adapter and a channel on their ASUS 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. ) 2.3.1 How Do You Configure the GUI RAID Manager to Use In-band SCSI? RAID Controller Adjustments Don't disconnect your RS-232C cable yet! It is required for another 10 minutes or so. Some adjustments must be made to the RAID 2-8 2.3 In-band SCSI
