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 The computer has two integrated SCSI controllers and an integrated Enhanced IDE controller. • The Enhanced IDE controller with one channel supports up to two IDE devices. An integrated Ultra ATA-33 controller on the PCI bus supports the fastest IDE devices (33 MB per second). • The Ultra wide 16-bit SCSI controller is dedicated to hard disk drives and supports up to five internal SCSI devices. • The Ultra narrow 8-bit SCSI controller supports up to two internal or seven external SCSI devices. When an external device is connected to the system, the narrow SCSI controller automatically switches to non-Ultra, or standard mode (maximum capacity of 10 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 Ultra wide 16-bit SCSI controller. The Adaptec® RAIDport adapter should be used with two 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 87. Refer to the drive's installation guide to see if you must set jumpers or if there is a special installation procedure to follow.
