I/O Architecture
Components within the I/O subsystem are the I/O controllers, internal peripheral bay, and
multifunction Core I/O. The figure below shows the basic block diagram of the I/O subsystem.
The HP Integrity rx7640 Server I/O architecture utilizes industry standard PCI X, and PCI-
express buses in a unique design for maximum performance, scalability, and reliability. To
achieve maximum performance and availability, each PCI/PCI-X slot on the I/O board is
controlled by its own Bus Converter ASIC and is also independently supported by its own half of
the dual hot swap controllers. All PCI slots are designed to be compliant with PCI Rev.2.2, PCI-
X Rev.2.0a, and PCI-express Gen1 specifications.
The PCI-X 2.0 I/O Backplane implemented an important change to power distribution to the I/O
partitions. The PCI-X Power supply bricks have been redesigned to allow the pair of them to be
N+1 redundant in operation. Both I/O partitions will sustain their operational state even if one of
the PCI bricks has failed. All the PCI voltages will remain within the PCI specification. These
power bricks are not part of the PCI-X I/O board assembly. They plug into the edge of the PCI-
X I/O Backplane to provide power to the board and they are not backwards compatible with the
previous PCI power bricks. Any PCI brick failures will be reported to the system so the failing
brick could be hot swapped.
Two different IO expansion bays are supported in the rx7640 chassis:
BP1: PCI-X IO BAY
:
The PCI-X board is two logically independent I/O circuits (or partitions) on one physical board:
Escalante 0 and its associated eight Gemini ASICs, Core I/O 0 and 8 PCI-X expansion slots
form PCI-X I/O Partition 0. Escalante 1 and its associated eight Gemini ASICs, Core I/O 1 and
8 PCI-X expansion slots form PCI-X I/O Partition 1.
BP2: Combined PCI-X / PCI-e IO BAY
:
The PCI-Express board comprises two logically independent I/O circuits (partitions) on one
physical board: Escalante 0 and its associated four Gemini (PCI-X) , four Apollo (PCIe) ASICs,
and their respective PCI/PCI-X/PCIe slots form PCI-Express I/O Partition 0 + Core I/O.
Escalante 1 and its associated four Gemini (PCI-X) , four Apollo (PCIe) ASICs, and their
respective PCI/PCI-X/PCIe slots form PCI-X I/O Partition 1 + Core I/O.
The internal peripheral bay supports up to four low profile disks and one removable media
device (one removable media device can be configured with one DVD+RW or one DAT (or
optionally, two slimline DVD modules). The internal disks are electrically divided into two pairs.
SCSI controller chips located on each core I/O board set supports each pair of internal disks.
This means that you must have both core I/O board sets in order to access both halves of the
peripheral bay.
