HP Integrity rx4610 Internals
4.41 HP Integrity rx4610
4.41.1 Overview
The Integrity rx4610 were HP’s first-generation Itanium server based on up to four Merced Itanium
processors and integrated into an 7U rack-mountable case. The rx4610 offered many I/O and expan-
sion options with ten PCI slots on four PCI buses (attached to 2.1GB/s of I/O bandwidth) and up to
64GB of main memory but was limited to only two internal SCSI drives.
The rx4610 is based on the Intel Itanium reference architecture the 82460GX chipset, which looks
like a mix of PC-style (Frontside Bus to the processor) and PA-RISC (I/O “ropes” from the central
chipset to PCI converters) platforms. The other HP system with Merced processors and the 82460GX
was the HP i2000 workstation. Both the i2000 and rx4610 were rather slow and buggy when compared
to contemporary PA-RISC systems.
Time of introduction: 2001, discontinued: Fall 2002, with prices at time of introduction between
$25,000 (733MHz base system)/$37,000 (800MHz base system) to more than $45,000 (larger sys-
tems).

Chipset
The rx4610 is based on Intel’s 82460GX chipset with four main components:
1. 82460GX SAC (System Address Chip) is the central chipset part:
System bus (FSB) for up to four processors 2.1GB/s (the SAC connects to the address and
control parts of the FSB)
Four I/O channels to which the PCI buses attach (via the WXBs/PXB) each channel is
533MB/s
Connection to the SDC
Address/control access to the main memory
2. Three 82460GX WXBs (Wide eXpansion Bridges) which connect the PCI 64/66 buses via three
I/O channels to the SAC
One I/O channel connects to two PCI 64/66 slots
One I/O channel connects to three PCI 64/66 slots
One I/O channel connects to three PCI 64/66 slots and the SCSI controller
