HP Cluster Platform Server and Workstation Overview

4 Server Blades
An HP Cluster Platform solution can be configured with p-Class or c-Class enclosures. This
chapter describes the BladeSystem enclosures and ProLiant BL servers and devices used in HP
Cluster Platform solutions. All server blades feature high-performance memory, iLO/iLO 2
advanced functionality, multiple general purpose Gigabit Ethernet network controllers, and
optional FC SAN connectivity. This chapter presents overviews of the following:
• HP BladeSystem p-Class (Section 4.1)
• HP ProLiant BL35p (Section 4.2)
• HP ProLiant BL45p (Section 4.3)
• HP BladeSystem c-Class enclosure (Section 4.4)
• HP ProLiant BL2x220c (Section 4.7)
• HP ProLiant BL260c (Section 4.8)
• HP ProLiant BL460c (Section 4.9)
• HP ProLiant BL480c (Section 4.10)
• HP ProLiant BL465c (Section 4.11)
• HP ProLiant BL465c G5(Section 4.12)
• HP ProLiant BL685c (Section 4.13)
• HP ProLiant BL685c G5(Section 4.14)
• HP Integrity BL860c (Section 4.15)
4.1 HP BladeSystem p-Class Overview
The HP BladeSystem p-Class solution consists of HP ProLiant BL server blades, network
interconnect components, a rack-centralized power subsystem, and management tools that enable
adaptive computing and is optimized for rapid deployment. Server blades feature
high-performance DDR memory, BIOS-enhanced RAID, iLO advanced functionality, two
general-purpose Gigabit Ethernet network controllers, and optional FC SAN connectivity.
HP BladeSystem p-Class 6U enclosures hold server blades and network interconnect options.
The server blades slide into the blade enclosure backplanes for power and network connections.
Each server blade enclosure has eight server blade bays in the center of the enclosure and two
interconnect bays at each end. The signals are routed from the server blades, across the server
blade enclosure backplane, and to the interconnect blades. The middle eight bays support server
blades.
Combinations of different series server blades are supported in the same server blade enclosure.
Each enclosure supports a pair of switch or patch panel interconnects for network cable
management. The upgraded enclosure also provides a single Ethernet port for connecting to the
iLO interface of every installed server blade. Some models of server blades, including the BL35p,
require the use of the enclosure with enhanced backplane components.
HP BladeSystem p-Class interconnects pass the network adapter (NIC) signals from the server
blades to external networks. The p-Class solution power subsystem is a 3U power enclosure that
holds up to six hot-pluggable power supplies. Additional power supplies and power enclosures
can be added to a system for redundancy. Power is carried from the power supplies in the power
enclosures to the server blade enclosures through bus bars (for powering multiple enclosures)
or a power bus box (for powering a single enclosure).
4.2 HP ProLiant BL35p Server Blade Overview
The HP ProLiant BL35p features up to two AMD Opteron 200 series low-power processors per
server blade. It has a modular, space-saving design that consumes less power and enables dense
rack architectures.
