MegaRAID Controller

MegaRAID has three independent RAID SCSI bus channels (0, 1, and 2), each using a
separate 53C770 SCSI controller. This allows the system to read or write data on several
disk drives simultaneously. The MegaRAID RAID controller board is shown in the
following figure. Channel 2 is the default internal RAID SCSI connector.

CAUTION

Ensure jumpers are installed as shown or erratic operation will occur.

Features
