Page 9: Introduction
This feature implements RAID capabilities on the system board resident SCSI channels. The AcceleRAID 200 controller must reside in a PCI slot specifically pre- configured to support SISL. The AcceleRAID 250 may reside in the dedicated slot (for a SISL implementation), or in any other PCI slot (to function as a standard PCI to Ultra2 SCSI RAID controller). -

Page 33: Procedural Overview
Chapter 4 Controller Start-up This chapter describes: • Start-up procedures • BIOS options • BIOS Configuration Utility • Driver Installation • What to check in case of problems This chapter describes the DAC960PTL controller start-up procedures and messages produced by the BIOS during start-up or re-boot. This chapter also explains three BIOS options that are available for configuring controller operation. -
Page 34: Bios Options Sequence
Controller Start-up Controller Start-up The controller start-up procedure is the first step in confirming that the controller is correctly installed and working properly. The start-up procedure should be performed prior to any software configuration. There are two start- up sequences: the BIOS Options sequence and the BIOS Configuration Utility sequence. -
Page 35: Setting Bios Options
Controller Start-up Setting BIOS Options The available BIOS options are: • BIOS disabled / enabled • CD-ROM boot disabled / disabled • 2GB / 8GB drive geometry BIOS Disable or Enable This option must be enabled in order to toggle the CDROM boot and the drive geometry parameters shown in the BIOS Options menu. - Page 36 BIOS Options Sequence Enable 8GByte or 2GByte Drives This setting affects how the BIOS reads the disk drives for the boot partition. Drive geometries can be toggled between 8 GB and 2 GB. The default is 2 GB. When the drive geometry is changed, the drive should be formatted at the operating system level.

Page 37: Using Raid Ezassist
Controller Start-up Note In the event that the RAID controller needs to be replaced, the current drive geometry will be restored from the configuration on disk (COD). Using RAID EzAssist Caution Configuration will destroy the data that already exists on all SCSI disk drives cabled to a SCSI channel embedded on a system board if the disks can be controlled by the AcceleRAID controller in a SISL configuration. - Page 38 Using RAID EzAssist Note If you want to do anything other than an automatic configuration, refer to the RAID EzAssist Configuration Utility User Reference Guide. To perform a RAID configuration with the Automatic Configuration option using RAID EzAssist, do the following: 1.

Page 65: Scsi Drive
Glossary SCSI SCSI is an acronym for “Small Computer Systems Interface,” although it is often used in large systems. The SCSI interface supports disk drives, tape drives, and CDROM drives. Narrow SCSI supports up to 7 devices on a channel, and Wide SCSI, Ultra SCSI, and Ultra2 SCSI support up to 15 devices on a channel. -

Standby Replacement of Disks (“Hot Spare”) The “Standby Replacement” (or “Hot Spare”) is one of the most important features the controller provides to achieve automatic, non-stop service with a high degree of fault-tolerance.
- Page 68 Stripe Order The order in which SCSI disk drives appear within a drive group. This order must be maintained, and is critical to the controller’s ability to ‘Rebuild’ failed drives. Stripe Size The stripe size is defined as the size, in kilobytes (1024 bytes) of a single I/O operation.
