SCSI Controller
The used SCSI controller is a LSI53C1010. It supports two dual U2W LVD SCSI buses with
a SCSI data transfer rate of up to 160 MByte/s for each channel. Both SCSI interfaces are
available via the front panel.

Both SCSI interfaces have an on−board termination which can be enabled and disabled
via on−board switches. By default, the SCSI termination is enabled.

SENTINEL64 PCI−to−PCI Bridge
The SENTINEL64 PCI−To−PCI bridge is used to connect the primary PCI bus A to the
secondary PCI bus B. For details about the SENTINEL64 device refer to the SENTINEL64
Reference Guide available via the Force Computers S.M.A.R.T. server.
