9.2 Internal SCSI configurations
Configuration with dual onboard SCSI controller (default)
The server has one dual onboard LVD/U2W-SCSI controller. Each of the SCSI
channels is connected with one SCSI backplane (lower backplane with channel
A and/or the upper with channel B).
An optional SCSI SE backup drive is connected to the lower SCSI backplane.
Configuration with 2-channel and/or 3-channel Disk Array Controller
The controller is installed into a PCI slot. The SCSI channels are connected
each with one of the SCSI backplanes (two hard disk drives each).
One free SCSI channel of the onboard LVD/U2W-SCSI controller is available for
the optional SCSI SE backup drive.
The second free SCSI channel of the onboard LVD/U2W-SCSI controller can
become used for external disk drives.
Supplementary channels of the disk array controller are available for external
hard disk drives systems.
