1 Introduction
The rx2620 server is a 2-socket server based on the Itanium®processor architecture.
The server supports the following operating systems: Microsoft Windows®, HP-UX,
Linux, and OpenVMS®. The server is available in either rack-mount or pedestal
configurations. The server accommodates up to 12 DIMMs and internal peripherals
including disks and a DVD. Its high availability features include hot-swap fans, power
supplies, and hot-plug disk drives.
Server Overview
The rx2620 server chassis is a 2U Electronics Industry Association (EIA) enclosure,
which mounts in any standard 19-inch EIA rack. All external cabling connects from
the rear of the enclosure. With the server installed in the rack, service access is
enhanced by the use of chassis slides. The server has bays to accommodate 1 + 1
redundant, hot-swappable power supplies, accessible from the front of the product.
There are three low-profile hot swappable hard drives accessible from the front, and
a slim-line optical drive for a CD-R, CD-RW, DVD-R, or DVD+RW. There are N + 1
redundant, hot-swappable server fans, all clearly identified and easily accessible.
Server status indication, a power switch, server locator switch, and LED are located
in the front within the bezel. A server locator switch and LED is in the back of the
server for easy identification in the rack. See Figure 1,Figure 2, and Figure 3 for front
and back views of the server.

This section provides a block diagram of the system board and descriptions of key
components (integrated circuits) on the board. Figure 4 shows a block diagram of the
server.

•“IDE Interface” (page 19)
•“1 Gb System LANs A and B” (page 19)
•“USB Connectors” (page 20)
•“Data Pathing Information” (page 20)
Processor Sockets
The system board consists of two zero insertion force (ZIF) processor sockets, the
core electronic complex (CEC), and circuitry for clock and power generation and
distribution, boundary scan, in-target probe, and debug.
The front side bus (FSB) is the IA64 processor bus, based on bus protocol from Intel.
Unlike previous PA-RISC microprocessors that utilized Hewlett Packard Enterprise
proprietary processor buses, this processor is designed to utilize the FSB. This allows
processor field replaceable units (FRUs) to be dropped in, provided that electrical
and mechanical compatibility and support circuitry exist. For the purposes of this
document, a FRU consists of a single processor with power pod, and the heat sink
assembly.
Each processor plugs directly into, and is powered by its own 12 V to 1.2 V power
pod. Other power for the system board comes from multiple on-board DC to DC
converters. Each processor is attached to the board through a ZIF socket and the
entire FRU secured by a heat sink.
Processor Bus
The FSB in this product runs at 200 MHz. Data on the FSB are transferred at a double
data rate, which allows a peak FSB bandwidth of 6.4 Gb/s.
ZX1 I/O and Memory Controller
The server supports the following features of the ZX1 I/O and memory controller chip:
•8.5 Gb/s peak I/O bandwidth
•Seven communication paths
•Peak memory bandwidth of 8.5 Gb/s
•Two memory cells, 144 data bits each
Memory
The memory subsystem provides two memory cells. Each cell is 144 data bits wide.
Each cell has six DIMM slots, which means a total of 12 DIMM slots are available.
The memory bus clock speed is 133 MHz, and the data transfer rate is 266
15

Mtransfers/s as data is clocked on both edges of the clock. The peak data bandwidth
for this memory subsystem design is 8.5 Gb/s. Load DIMMs in quads with qualified
modules. Memory is protected by data ECC, and the hardware implementation
supports chip-spare.
The minimum amount of memory supported by the server is 1 GB (four 256 MB
modules). The maximum amount of memory supported by the server is 32 GB (eight
4 GB modules).
This design does not support any nonindustry-standard DDR DIMMs. Only qualified
DIMMs are supported. Figure 5 shows a block diagram of the server memory.
Figure 5 Memory Block Diagram
Memory Architecture
The I/O ASIC memory interface supports two DDR cells. Each cell is 144 data bits
wide. The memory subsystem physical design uses a comb-filter termination scheme
for the data and the address and control buses. This topology is similar to other DDR
designs. Clocks are distributed directly from the I/O ASIC. Each clock pair drives two
DIMMs.
Memory data is protected by the ECC. Eight ECC bits per DIMM protect 64 bits of
data. The use of ECC allows correction of single-bit errors, and detection of multi-bit
errors. Only DIMMs with ECC are qualified or supported.
DIMMs
The memory subsystem supports only DDR SDRAM (Double Data Rate Synchronous
Dynamic Random Access Memory) technology utilizing industry-standard PC-1600
type DDR SDRAM DIMMs, 1.2" tall. The DIMMs use a 184-pin JEDEC standard
connector.

DIMMs are loaded in a group of four, known as a quad. All four DIMMs in a quad must
be the same size. Table 4 summarizes the memory solutions.

Chip Spare Functionality
Chip spare enables an entire DDR SDRAM chip on a DIMM to be bypassed in the
event that a multi-bit error is detected on the DDR SDRAM. To use the chip spare
functionality on your server, use only DIMMs built with ×4 DDR SDRAM parts, and
load these DIMMs in quads.
The memory subsystem design supports the I/O ASIC chip spare functionality. Chip
spare enables an entire SDRAM chip on a DIMM to be bypassed/replaced in the
event that a multi-bit error is detected on that SDRAM. To use the chip spare
functionality, use only DIMMs built with x4 SDRAM parts, and load these DIMMs in
quads (two DIMMs per memory cell, loaded in the same location in each memory
cell). Each DIMM within a quad must be identical to all the other DIMMs in the quad.
Chip spare is achieved if four identical DIMMs are loaded into a quad. If more DIMMs
are added, they must be loaded in quads to maintain the chip spare functionality. So,
if more DIMMs are added in to the example case, four identical DIMMs (identical to
each other, but can be different from the original quad that was loaded) must be
loaded into the next quad. However, if you are using 4 GB DIMMS, the only
configuration supported is eight 4 GB DIMMS in the first three quads, with no other
DIMMs in the remaining quad. For slot and quad locations, see Figure 37 (page 48).
Serial Presence Detect
Each DIMM contains an I2C electronically erasable programmable read-only memory
(EEPROM) whose content describes the module characteristics. This feature is called
serial presence detect (SPD). Firmware typically uses this information to detect
unmatched pairs of DIMMs and configure certain memory subsystem parameters.
The SPD information for DIMMs loaded in the server is also accessible to the BMC
through the I2C bus.
I/O Bus Interface
The I/O bus interface provides these features:
•Industry-standard PCI 33 MHz and 66 MHz, PCI-X 66 MHz to 133 MHz, 32 or
64 data bit support
•3.3 V PCI only (does not support 5 V PCI)
•DMA performance optimization
•3.3 V or Universal keyed PCI card support (not 5 V keyed PCI cards)
•Up to four PCI sockets

Dual Serial Controller
The dual serial controller is a dual universal asynchronous receiver and transmitter
(DUART). This chip provides enhanced UART functions with 16-byte first-in, first-out
(FIFO), a modem control interface. Registers on this chip provide onboard error
indications and operation status. An internal loopback capability provides onboard
diagnostics.
Features include:
•Data rates up to 115.2 kbps
•16550A fully compatible controller
•A 16-byte transmit FIFO that reduces the bandwidth requirement of the external
CPU
•A 16-byte receive FIFO with four selectable interrupt trigger levels and error flags
that reduce the bandwidth requirement of the external CPU
•UART control that provides independent transmit and receive
•Modem control signals (-CTS, -RTS, -DSR, -DTR, -RI, -CD, and software

Baseboard Management Controller
The baseboard management controller (BMC) supports the industry-standard Intelligent
Platform Management Interface (IPMI) specification. This specification describes the

SCSI Controller
The SCSI controller is an LSI Logic 53C1030 chip. This chip is fully compliant with
the SCSI Peripheral Interface-3 Specification (SPI-3). It has two independent SCSI
channels supporting devices at speeds up to 320 Mb/s each. The 53C1030 adheres
to the PCI-X addendum to the PCI Local Specification and is hard-wired to PCI ID 1,
which corresponds to bit 17 of the PCI AD bus.
IDE Interface
The IDE controller (PCI649) supports the ATAPI zero to five modes (from 16 to 100
Mb/s). The usable speed on this server is limited to 16 MHz (ATA-33 mode, 33 Mb/s)
because the slimline CD/DVD devices do not support the ATA-66 and 100 modes.
The primary IDE channel is the only channel that is implemented. The IDE cable
provides only one drive connector, of the primary type, for the DVD peripheral.
