Setting the Termination Mode of the Intel RAID Controller SRCU32
The onboard termination of the RAID controller can be changed within Storage Console. The
default setting is "Auto" (jumpers in ‘Soft-Switch mode). In this mode, the controller automatically
activates/ deactivates termination based on cable connection (if internal and external connectors are
used of a specific channel then the termination is off, otherwise on). "On", "Off" turns the
termination on or off regardless of the connected cables. In addition to the "soft-switch" jumper
setting, termination jumpers force termination always ON or OFF - no matter of the software
settings or cables detected.
Configurable SCSI Parameters
When a SCSI hard drive is initialized the first time by the RAID controller, its SCSI parameters are
automatically set to their optimal settings. Manual configuration is not required. However, the
RAID controller allows for the custom configuration of several SCSI parameters on a hard
drive-by-hard drive basis. There are several settings that can be configured by using the Storage
Console menu Advanced Setup

Parameter/Initialize. Most settings are set automatically and cannot be configured manually. See
the following table.
Table 1. Hard Drive SCSI Parameters
Parameter Setting/Value Description
Synch. Transfer Not
Configurable This setting, when enabled, allows the controller to operate in
synchronous transfer mode.
Synch. Transfer
Rate Not
Configurable Allows for the setting of the speed for the SCSI hard drives (160 MB/sec
for U160 drives). No matter the setting, the SCSI bus will negotiate the
fastest speed up to this setting. Lowering the setting will force the hard
drive to transfer at the lower speed.
Disconnect Not
Configurable
Enabling this setting allows for the hard drive to disconnect from the
SCSI bus when it’s not participating in a transfer. This allows for
optimal bus utilization by all devices on the bus.
