Raid Configuration - NEC EXPRESS5800 LC1400 series User Manual

RAID Configuration

The RAID options available for your system are the Mylex AcceleRAID
Mylex AcceleRAID 250 Controller boards, which gives your system the added security
of fault tolerance.
If you order a system with a RAID controller, the system is pre-cabled at the factory
(see "RAID System Cabling Configuration" figures below.)
If you are adding either the AcceleRAID
must install, cable, and configure the controller. Refer to "Installing a RAID Controller
Board" in Chapter 4.
Note:
controller must be turned OFF if you install the optional Mylex
AcceleRAID
system. Refer to "Symbios Configuration Utility" found in Chapter 3.
Note that Jumper JP10 (see figure below) that enables the SCSI Interrupt Steering
Logic (SISL) control on the RAID controller must be in its off position (not jumpered),
which is its default position.
Note:
configuration. If your system requires a jumper change, change only
the jumper setting for that condition. Otherwise, keep the jumper at
its factory setting.
