Setting Controller Configuration - Asus PCI-DA2100 User Manual

4.5 Setting Controller
Configuration
The GUI RAID Manager enables you to modify the
configuration of the disk array controller from your manager
console. You can enable or disable the write-back cache of the
system, set whether or not the controller will reset the SCSI bus
during power-on, stagger the drives' motor spin-up sequence, set
the baud rate of the controller's RS-232 port, and modify the
station password.
The following describes the user-configurable parameters:
Write-Back.
disable the write-back cache of the system. The write-
back cache allows write data to be stored in the cache
memory prior to writing to the disk, thereby pipelining the
I/O write process.
SCSI Reset on Power-up. This parameter determines
whether or not the controller will assert SCSI bus reset
during power-on initialization.
Staggered Drive Spin-Up.
whether or not the controller will sequence the drives to
start spinning in succession at five-second intervals.
Enabling staggered drive spin-up can help prevent
overloading the power supply when many drives spin up at
the same time.
RS-232 Baud Rate. This parameter sets the baud rate of
the RS-232 port on the controller. When connecting a host
computer, terminal, or other device (such as a modem)
onto this port, ensure that their baud rates are set
accordingly; otherwise, there will be communication
problems.
