Hardware
Introduction – Assumptions
The AcceleRAID 150, AcceleRAID 200 and the AcceleRAID 250 are very
versatile Ultra2 SCSI, LVD RAID controllers. There are literally thousands
of possible hardware configurations. In order to keep this Quick Installation
Guide down to a manageable size, the following assumptions are being
made:
• A RAID 0, 1, or 5 installation is being installed.
• The user is familiar with Windows NT
®
or Novell
®
NetWare
®
.
• The user is familiar with disk drive and RAID terminology.
Types of Installations
There are two types of installations:
• Standard Installation
• SCSI Interrupt Steering Logic (SISL) Installation
Standard Installation
In a standard installation, the AcceleRAID 150 or the AcceleRAID 250
functions as a single-channel, standard PCI to Ultra2 SCSI, LVD RAID
controller. In a standard installation, the AcceleRAID 150 or 250 can be
installed into any system board with an available PCI (2.1 compliant) slot.
SCSI Interrupt Steering Logic (SISL) Installation
In a SISL installation, the AcceleRAID 200 adds RAID functionality to a
system board that has one or more embedded SCSI channels. The
AcceleRAID 150 or 250 adds an Ultra2 SCSI, LVD RAID channel as well as
RAID functionality to a system board that has one or more embedded SCSI
channels. For a SISL implementation, the AcceleRAID controllers must be
plugged into a special, pre-wired PCI slot in a system board that is specially
designed for this type of installation. Check with the manufacturer of your
system board to find out if it has embedded SCSI channels that can be
controlled by a PCI to SCSI RAID controller with SCSI Interrupt Steering
Logic (a requirement for the AcceleRAID 200).
