Hard-Disk Drive Options: OptiPlex GXi
Low-Profile Chassis | Midsize Chassis | Mini Tower Chassis | EIDE Subsystem
Low-Profile Chassis
The hard-disk drive assembly (consisting of the hard-disk drive and the hard-disk drive bracket) is located inside the left front area of the chassis and is attached to the
bottom of the chassis. One EIDE or SCSI 1-inch-high hard-disk drive can be mounted on the hard-disk drive mounting bracket.
Midsize Chassis
The hard-disk drive bracket is located next to the externally accessible drive bays at the front of the computer. The hard-disk drive bracket can contain either (1) or (2)
1-inch-high EIDE or SCSI hard-disk drives, or it can hold (1) 1-inch-high EIDE or SCSI hard-disk drive and (1) 1.6-inch-high EIDE or SCSI hard-disk drive.
Mini Tower Chassis
The hard-disk drive brackets are located under the externally accessible drive bays at the front of the computer. The system supports 3.5-inch EIDE or SCSI drives.
The system brackets can hold (1) 1-inch-high drive and (1) 1.6-inch-high hard-disk drive.
EIDE Subsystem
The EIDE subsystem provides 2 mode-4, DMA bus-mastered EIDE interfaces, each of which can support up to 2 EIDE devices. The EIDE controller attaches to the
high-speed PCI local bus.
The primary EIDE interface (IDE1) provides support for up to 2 high-performance EIDE devices, such as hard-disk drives. The computer's boot drive should be
connected to the primary EIDE interface.
The secondary EIDE interface (IDE2) provides support for up to 2 additional EIDE devices, typically EIDE tape drives or CD-ROM drives.
NOTE: The externally accessible drive bays at the front of the computer are normally used for diskette drives, CD-ROM drives, and/or tape drives.
Hard-disk drives should be installed in the internal hard-disk drive bracket(s). For additional information about the data storage subsystem, see
Chapter 7, "Installing Drives," in the
Reference and Installation Guide .
