Specifications

The HP 9000 rp7440 and rp8440 Servers share many system components and design features as
seen below. Figure 3 shows a front/side and rear view of the HP 9000 rp8440 Server with its front
plastic bezel and top and left side panels removed.
A peripheral bay located at the top front of the HP 9000 rp8440 Server provides space for four hot-
plug disk drives and two removable media devices (DVD or DAT). Directly below the peripheral bay
are two redundant PCI-X power bricks, which supply DC power for the PCI-X backplane. Below the
power supplies are nine redundant hot-swappable cooling fans. These fans pull cool air in from the
front and force air to the rear, cooling the system’s internal components. At the bottom is the bulk
power supply bay, which houses up to six redundant (2N+1) hot-swap power supplies.
Figure 3 also shows the side of the HP 9000 rp8440 Server, with a view of the cell card cage. This
cage supports up to four cell boards on which processors, memory, and cell controller chips reside.

Front and side view Rear view
The rear view of the HP 9000 rp8440 Server shows the location of the 12 hot-swappable 120-mm
exhaust fans and the I/O bay bulkhead directly above them. The core I/O cards are located at the
right edge of the unit.
This view shows the system backplane board, which houses the high-bandwidth crossbar used for
communications between cell cards, I/O, and internal peripherals. The HP 9000 rp8440 Server I/O
card bay is located at the top rear of the system. It contains 16 PCI-X card slots, all supporting hot-
plug functionality.
The bottom rear of the HP 9000 rp8440 Server has inputs for the 2+2 redundant line cords. Because
of the high degree of connectivity offered in the HP 9000 rp8440 Server, a cable management arm
specific for the HP 9000 rp8440 Server (not shown) is provided for dressing cables and simplifying
cable routing.
