1 HP Blade Server bh7800 Overview

The HP Blade Server bh7800 provides customers with a single chassis that can house up to 16 functionally separate servers, controlled by one management blade. The form factor for all the blades uses the CompactPCI standard. The chassis mounts in a standard 19-inch EIA rack, in either a two column or four

Chapter 1

HP Blade Server bh7800 Overview

column style rack. Hewlett-Packard Company offers kits for either type rack. The chassis provides slots in the front and rear for installation of server blades, and network blades. Each side accommodates 18 blades and can house up to eight server blades per side.

This chapter provides a high level overview of the various components that comprise the blade server. It is not the intention of this chapter to cover how to operate the blade server.

Chapter 1

Display Panel

The bh7800 display panel provides the controls and indicators commonly used when operating the bh7800. There are two LCD display assemblies on the bh7800. Remote control over a network is another method used to operate the bh7800. One display is in the front, just above the card cage. The other is in the rear, just above the card cage. Both show identical data and are visible regardless of which side of the product you are on. The rear display assembly is hinged so that it can be lifted up out of the way for access to the hot swap fan modules. The LCD display panels allow most initialization and system monitoring functions to be performed without connecting via Telnet or directly connecting to the management blade’s serial port. The display panel is shown in Figure 1-1.

HP Blade Server bh7800 Overview

System Backplane

The passive system backplane is centrally located in the bh7800 to accommodate front and rear card cages. 18 CompactPCI slots are available on each side with up to five connectors per slot. For the CompactPCI standard, the lower two connectors are used for CompactPCI standard connections, and the upper three connectors are for custom user applications. Additionally, the rear of the backplane has four power connections (two for each power supply). The front of the backplane also contains the fan harness connector and two LCD display cable connections. All connectors used on the backplane are press-fit. No special tool is needed to insert or remove the connectors.

Figure 1-2 bh7800 Backplane

Chapter 1

HP Blade Server bh7800 Overview

Power Supplies

Each power supply uses two DC connectors that plug into the backplane, and an AC connector brings line power into the unit. Two power supplies and two power cords ship with the system.

Each supply contains an internal fan for cooling. In the rear of each supply are two insertion/extraction handles and latch assemblies for ease of inserting or removing each power supply. Two captive screws secure each power supply to the system chassis.

A solid green LED indicates normal operation for either power supply. A solid yellow LED indicates a power supply failure. Power supplies are hot swappable.

HP Server bc1100

Up to 16 1 slot IA-32 server blades can be inserted in the bh7800 chassis. The 1 slot, 1way IA-32 blade server is a self-contained system. It includes all memory, processor, firmware, I/O adapters, and core I/O required to install the operating system. The board is CompactPCI and hot plug compliant and operates as a CompactPCI master in the host slot. It is also Network Equipment Building Standards (NEBS) compliant. Some I/O connections will be driven through the backplane and some local connections will be available from the front panel.

A daughter board known as the Remote Management Card (RMC) provides LAN-based system console access as well as remote system management functions. LAN-based access to the system console via Telnet is provided to initially configure parameters stored in firmware on the blade. Remote system management functions include power, reboot and inventory control.

Chapter 1

HP Blade Server bh7800 Overview

Network Blade

The network blade is a 24-port 10/100 switch with a gigabit uplink connection. The blade provides 16 of the 24 ports to the backplane, and 8 remaining ports out to the bulkhead. In addition, the network blade comes in three uplink options: Tx (copper), Sx (short-wave optical), or Lx (long-wave optical).

The bh7800 system must contain one network blade, but can optionally contain two. The backplane actually contains two separate LANs, LAN-A and LAN-B, so that a second blade provides backup protection for the LAN segment.

The uplink connection aggregates all communications in the bh7800. This gigabit connection aggregates the traffic from all 16 ports.

The blade may be hot swapped without taking down a live system. Of course, if only one switch is in the cabinet, all external communications cease while the blade is being swapped. With a second switch in the chassis, external communications are only interrupted on the LAN connected to the corresponding switch being hot swapped. The switch in front slot 12 corresponds to LAN-A and the switch in rear slot 13 corresponds to LAN-B.

Management LAN Blade

The two Rear Transition Modules (RTMs) are unique in the bh7800 product. The RTM is a pseudo standard CompactPCI solution. Each RTM is a 3U blade rather than a 6U blade. CompactPCI card format and the bulkhead is not a CompactPCI standard. A custom carrier holds each PCA in the bh7800 backplane. The custom card guide is inserted in a dedicated location in the rear card cage. The RTM is more commonly referred to as the management LAN blade.

Figure 1-6 Management LAN Blade (shown with carrier)

Chapter 1

HP Blade Server bh7800 Overview

Management Blade

The bh7800 includes a management blade that allows remote and local management of the individual server and network blades. The blade monitors the chassis environment such as power, temperature, and overall server blade health. The blade can be accessed via a serial connection on the chassis or it can be accessed via the control and management LAN.

The blade provides management support for the console LAN management signals. Provision for control of the console LAN management signals for the sixteen IA-32 server blades or two LAN switches is in the 38 slot chassis.

Chapter 1

HP Blade Server bh7800 Overview

Fan Modules

There are two fan module assemblies in the bh7800. They are hot swap modules. Each fan module has an LED to indicate fan failure. Also, each fan can go into the fan module only one way due to the length and location of the fan cable with its blind mate connector. Once each fan module is securely seated in the chassis, two screws are tightened to secure each fan and prevent it from backing out of the chassis due to vibration.
