High-Availability Slider Rails; Cabinet Spacing Requirements; Standalone/Deskside Configuration; In-Box Upgrade From Pa-Risc Servers - HP rx2600 Overview

High-availability slider rails

There are two rail options, static or slider, available for racking the rx5670 into an HP cabinet. The high-
availability (HA) slider rails were designed to allow easy service access to the system as well as to enable hot-
swapping of the four fans in the side cavity.
With the HA slider rails, the unit can be completely serviced without removing it from the rack, thus allowing side-
by-side racks of systems to be completely supported without sacrificing floor space for side access to the system.
For this reason, the high-availability slider rails are highly recommended.
Note: The slider mechanism occupies one EIA unit of rack space. When used with the rx5670, the combination
will occupy eight EIA units of rack space. Static rails do not consume EIA space within the cabinet, leaving more
EIA space for peripherals. However, using static rails prohibits hot-swapping of the I/O bay fans.

Cabinet spacing requirements

The rx5670 requires a minimum of 24 inches (61 cm) of free space in both the front and rear of the cabinet for
proper ventilation. During product installation and servicing, a total of 32 inches (82 cm) of free space is needed
at the front of the cabinet. The depth of HP Rack System/E cabinets is 39 inches (99 cm). Therefore, a minimum of
87 inches (221 cm) of total space is needed for each cabinet during normal operation. An additional 8 inches
(21 cm) is needed during installation and servicing.

Standalone/Deskside configuration

When a cabinet is not desired, the rx5670 is also available in a standalone configuration. The standalone system
is ideal for an office environment, under a desk, or on a shelf. The standalone configuration utilizes the same
internal chassis and front plastic bezel as the racked version. However, a sheet metal cover, base, and casters are
added for functionality and aesthetics. Casters can be removed when not desired.
Note: Dimensions for standalone/deskside configuration: H = 14.5 inches (36.8 cm), D = 30.5 inches (77.5 cm),
W = 19 inches (48.2 cm).

In-box upgrade from PA-RISC servers

Any PA-RISC-based HP Server rp5400, rp5430, rp5450, rp5470, or HP 9000 L-Class server is field-upgradable
to an HP Integrity rx5670. The rx5670 chassis, power, and cooling infrastructure are identical to legacy rp54xx
and L-Class systems. Customers simply order the appropriate upgrade product numbers, and an HP customer
engineer will arrive to swap the components. Please see the HP Integrity rx5670 Ordering Guide for more
information.
Itanium 2–based HP Integrity server architecture
This section discusses the electrical architecture of the HP Integrity rx2600, rx4640, and rx5670. Topics covered
include the HP zx1 Chipset, block diagrams, and I/O layout.
Overview of the HP Scalable Processor Chipset zx1
HP develops chipsets to meet the needs of enterprise and technical customers. In a world where every company
has access to the same 64-bit processors, HP's strength is to develop and tune systems to deliver the kind of
performance and reliability that IT, engineering, and research professionals demand.
The HP zx1 Chipset is the central building block of the HP Integrity rx2600, rx4640, and rx5670 servers. The
HP zx1 Chipset is a modular three-chip solution designed for cost-effective, high-bandwidth, low-latency 1- to 4-
way symmetrical multiprocessing (SMP) servers and workstations. Invented entirely by HP, the HP zx1 Chipset is
an exclusive value-add in the standards-based world of Itanium 2–based platform computing.
The HP zx1 Chipset consists of three modular components:
• The HP zx1 Chipset memory and I/O controller connects to the processor bus and contains dual memory
controllers and the I/O cache controller. It interfaces to the Intel Itanium 2 processor bus and provides a low-
latency connection to DDR memory, either directly or through zx1 scalable memory expanders. The controller
can connect up to 12 zx1 memory expanders for quadruple the base memory capacity. It can also connect up
to eight zx1 I/O adapters, capable of sustaining 4.0 GB/s of I/O bandwidth.
