2 How to Install Accessories Inside Your PC Workstation Installing Mass Storage Devices Installing a Hard Disk Drive Disk Striping NOTE Before Installing an IDE Hard Disk This PC Workstation has an integrated Ultra SCSI controller, an Ultra SCSI interface board and an integrated Ultra ATA-33 IDE controller. • The Ultra ATA-33 IDE controller, on the PCI bus, supports up to two fast (33 MB per second) IDE devices. • The Ultra wide 16-bit SCSI controller is dedicated to hard disk drives and supports up to five internal SCSI devices. • The Ultra SCSI 16-bit interface board, installed in a PCI slot, supports up to 13 external 16-bit SCSI devices and automatically switches to non-Ultra or standard mode (data transfer rate of 20 MB per second). The Ultra 8-bit internal connector supports up to two internal peripherals at up to 20 MB per second. To achieve top performance through disk striping, a RAIDport™ is provided on the system board aligned with PCI socket 3. When the Adaptec® RAIDport adapter is installed in the PCI socket and RAIDport, the adapter sets up and accelerates disk striping on hard disks connected to the internal UltraWide 16-bit SCSI controller. The Adaptec® RAIDport adapter should be used with one or two stripped hard disks. Disk striping is supported only in Windows NT 4.0. The Adaptec CI/O Array Manager software can be used to manage and view the performance of the adapter. Although the RAIDport adapter is normally set up to maximize disk performance ("RAID 0" configuration), it can instead be configured to provide mirroring for extra data security ("RAID 1" configuration). For more information, refer to "The HP FastRAID Option" on page 94. Refer to the drive's installation guide to see if you must set jumpers or if there is a special installation procedure to follow.
