What is a Blade?

Blade-server with its cover on ready for insertion into the BladeCenter Chassis

• A “Blade” contains the core components of a server• Each Blade has:

Processor(s) Memory Internal storage (optional) Network Interface Cards (NIC) Optional plug-in components

• The Blade-server plugs into the midplane of a “Chassis” that provides common functions as:

Management console Access (KVM) Power supplies Cooling Fans Network Connectivity ( LAN, SAN, NAS, HPC) Shared media devices (CD-ROM and diskette drives) Optional Modules to support additional functionalities

JS21 - Memory

The BladeCenter JS21 supports:● Double Data Rate (DDR) ECC

Registered SDRAM memory ● 4 DIMM slots, populated in

matched pairs● The installed DIMMs on a

BladeCenter JS21 must be all PC2-3200 (400 MHz) or PC2-4200 (533 MHz). A mix of the two is not supported in a single BladeCenter JS21.

● A pair of installed DIMMs must be the same size.


PCI-Express

– Point to point serial interconnect with packetized, layered protocol

– 2.6 Gbits/s per-pin pair in each direction (speed scale in future generations)

– Dual simplex connection– Scalable bus widths– Embedded clocking technique using

8 bit/10 bit encoding– Isochronous Data transfer support– Compatible with PCI at the software

layers

PCI-Express (PCI-E) is the successor to PCI and PCI-X bus systems, realized by point-to-point implementation with the following general characteristics:


JS21 - I/O Connectivity

JS21 blade server with no daughter cards installed

With additional Dual Gigabit Ethernet daughter card installed

With future high-speed PCI-E daughter card installed*

*PCI-E daughter cards not yet available

With integrated PCI-Express and support for legacy I/O adapters, the JS21 offers backwards compatibility for BladeCenter and forward compatibility for connectivity to the high-speed fabric of BladeCenter H Note additional connectors

for high-speed backplane


JS21 - SAS Storage Subsystem

● Up to two internal 2.5" 10,000 rpm Small Form Factor Serial Attached SCSI (SAS) hard disk drives for up to 146GB of storage

● Integrated support for RAID-10 mirroring

● SCSI-based enterprise reliability combined with increased performance


JS21 - Diagnostics Tools

● Light Path Diagnostics● Power-on self-test (POST)

– Firmware checkpoints and error codes The firmware checkpoints are progress codes that your blade server displays during POST.

● Firmware error codes and location codes– Some firmware error codes also include location codes. The location code

information is required to identify the failing component.● Diagnostic utilities for the Linux and AIX operating systems

– Available from IBM http://www.ibm.com/servers/eservers/support/bladecenter/ ● To run stand-alone diagnostics you must establish a Serial Over LAN (SOL) connection

and start an SOL session on the blade server. Then you can: – Run stand-alone diagnostics from CD-ROM – Run stand-alone diagnostics from management (NIM) server
