Specifications
In practice, PCI-X I/O cards requiring the largest amount of bandwidth should be configured into the
dual-link slots. Because each I/O slot has a dedicated bus, any slot can be hot-plugged or serviced
without affecting other slots.
Core I/O
The HP 9000 rp7440 and rp8440 Servers are purchased with one or two core I/O card products. In
both systems, core I/O provides console, Ultra320 SCSI, Gigabit LAN, and Management Processor
(MP) functionality, along with SCSI controllers for the peripheral bay. The second core I/O product
can be used to enable dual partitioning, provide access to a second set of disk drives, and provide
redundant MP functionality. In the HP 9000 rp8440 Server, the second core I/O product also
enables the use of an additional removable media device. Although core I/O provides the same
functionality in both the HP 9000 rp7440 and rp8440 Servers, the physical implementation is
different. To accommodate size limitations, the core I/O in the HP 9000 rp7440 Server is divided
across two separate boards, while the core I/O in the HP 9000 rp8440 Server is implemented on
one physical board. The following sections detail the core I/O implementation in each system.
HP 9000 rp7440 Server core I/O
The HP 9000 rp7440 Server chassis supports up to two core I/O card sets. Each set contains two
cards (MP/SCSI and LAN/SCSI), which are installed in different locations: MP/SCSI cards are
installed along the right rear vertical edge of the chassis; LAN/SCSI cards are installed in the PCI-X
card bay. A minimum of one core I/O card set must be ordered with each system; the optional
second core I/O card set can be used to enable hardware partitioning or to utilize the full capacity of
the built-in mass storage bays.
Both core I/O card sets are identical. In the primary and secondary core I/O set, the LAN/SCSI
board is supported by a single 530 MB/s link. In the primary and secondary core I/O set, the two
SCSI controllers—one in the LAN/SCSI card and one in the MP/SCSI card—each support a single
internal disk drive.
