Page 11: Introduction
Figure 1-1. DAC1164P Disk Array Controller Product Description The Mylex eXtremeRAID 1100 (DAC1164P™) controller is a PCI to Ultra2 SCSI RAID controller with 64-bit PCI capability. With up to three Ultra2 SCSI channels, and a cache memory battery backup, this controller provides the speed and functionality required by high demand server platforms. -
Page 12: Controller Features
Product Description Controller Features Features of the DAC1164P controller include: • Up to three Ultra2 SCSI channels that support RAID levels 0, 1, 3, 5, 0+1, 10, 30, and 50. • Low-Voltage Differential (LVD) Wide Ultra2 SCSI (Fast 40). Controller also supports SCSI 1, 2, or 3, single-ended. •... -

Page 15: Preinstallation Planning
• SCSI drive preparation • Limitations on mixing various SCSI drive types Mylex disk array controllers are designed to work in a variety of SCSI RAID application environments. Certain configuration steps need to be performed prior to installing the controller into a RAID environment. - Page 16 SCSI Termination Each end of a SCSI bus must be terminated to maintain proper voltage levels for SCSI control and data signals. The device used for this purpose is called a terminator, and it can be built into a controller, a SCSI peripheral device, or it can be a plug placed on the connector at the very end of a SCSI bus.
- Page 17 Preinstallation Planning Figure 2-1. DAC1164P Termination Examples Note When connecting SCSI devices, it is better to terminate the ends of the SCSI bus itself than it is to terminate the end devices on the bus. This allows hot swap devices to be added or removed from the SCSI bus without affecting termination.
- Page 18 SCSI Cabling The controller supports up to three Ultra2 SCSI channels. Each channel supports up to 15 devices. LVD Mode The controller supports Ultra2 SCSI with LVD. If all drives attached to a controller drive channel support Ultra2 SCSI with LVD, then that channel will operate at 80 MB.

Page 23: External Scsi Connectors
Installation External SCSI Connectors The external SCSI connectors on the controller are female, Very High Density Cable Interconnect (VHDCI) connectors. The cables should have the VHDCI offset connector at one end and a High Density, 68-pin connector at the other end. Such cables with the correct offset hood and connector assembly are required if cables are to be connected to external channels 0 and 2 at one time. -
Page 24: Safety Considerations
Safety Considerations Safety Considerations Be sure to observe the following precautions before beginning the controller installation procedure: Caution Anti-static handling procedures are required. Leave the controller in its anti-static bag until it is time to plug the controller into the PCI slot. The use of a grounded wrist strap and other ESD protective measures are highly recommended. -

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 DAC1164P 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 28: 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 29: 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 CD-ROM boot and the drive geometry parameters shown in the BIOS Options menu. - Page 30 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.

Under RAID EzAssist, the cache line size (also known as “segment size”) should be based on the stripe size you selected. The default cache line size for Mylex eXtremeRAID controllers is 8K. Channel Refers to one SCSI bus on a disk array controller. Each disk array controller provides at least one channel. - Page 60 Since the problem has been resolved, no error is reported to the system. Note The soft error counter is incremented in this case. The soft error count can be viewed using the Mylex disk array configuration utilities.
