HP 9000 rp8440 Server internal peripheral bay
The HP 9000 rp8440 Server internal peripheral bay is located at the top front of the system chassis.
The peripheral bay holds up to four low-profile hot-plug disks and two removable media devices.
Each HP 9000 rp8440 Server core I/O card contains two dual-channel SCSI controller chips that
support the SCSI devices in the internal peripheral bay. Each core I/O card supports two internal
disks and one removable media device, each on a dedicated 40 MB/s SCSI channel. If use of more
than two internal disks or one removable-media device is needed, the HP 9000 rp8440 Server
requires both core I/O cards. This architecture also provides an added degree of availability by
supporting full disk mirroring across independent buses, controllers, core I/O cards, and master I/O
controller chips.
Hot-plug disk drives—The HP 9000 rp8440 Server holds up to four SCSI disks, which are accessible
from the front of the server. These hot-plug disks can be removed and inserted while the HP 9000
rp8440 Server continues to operate. Three disk sizes are currently supported: 36 GB, 15,000 rpm;
73 GB, 15,000 rpm; 146 GB, 10,000 rpm; and 300 GB, 10,000 rpm.
Removable-media bays—The HP 9000 rp8440 Server contains two removable-media bays, which
support a half height DVD drive or a half-height DAT drive. Access to these devices is also from the
front of the server. The DVD drive provides enhanced features while preserving backward read
compatibility with CD-ROM drives. Data transfer rates of up to 6.75 MB/s are achieved with the DVD
format; 4.8 MB/s can be achieved using the CD-R format. The DAT drive has a maximum storage
capacity of 72 GB, with a peak transfer rate of 21.6 GB/hour (compressed).
HP Server Expansion Unit 2
The HP Server Expansion Unit 2 (SEU-2) is an add-on chassis containing I/O resources that
complement the I/O and partitioning capabilities within the HP 9000 rp8440 Server. The HP 9000
rp8440 Server contains built-in ability to connect to the HP SEU-2. Connection to the SEU-2 doubles
the amount of the HP 9000 rp8440 Server I/O resources, and the SEU-2 enables the creation of two
additional nPars within the chassis. The following features are provided by the SEU-2:
• Sixteen high-performance PCI-X I/O slots
• Eight slots that are 266-MHz x 64-bit capable
• Six slots that are 133-MHz × 64-bit capable
• All slots support hot-plug
• All slots supported by independent dual or single links
• Four disk drive bays
• Two removable half-height media slots (either DVD or DAT)
• Two additional nPars in the HP 9000 rp8440 Server host are enabled
• Two core I/O slots
• Redundant and hot-swap fans and bulk power supplies
• Redundant line cords for dual grid support
• 9U rack-mount chassis
• Certified under Uptime Institute’s Fault Tolerant Power Compliance Specification
