20. IBM BladeCenter HS40 Architecture
Topic 2
January 2004
IBM BladeCenter HS40 Architecture
Student Notes
The BladeCenter HS40 uses the ServerWorks Grand Champion LE (GC-LE) chipset.
The GC-LE is the memory controller and interface for the I/O buses supporting four Xeon processors and two DDR-SDRAM memory channels.
The GC-LE has two Inter Module Buses (IMB2), one to a Champion I/O Bridge (CIOB-X2) and another to the BladeCenter SCSI Expansion (BSE). The GC-LE is also connected through a Thin IMB bus to the Champion South Bridge (CSB6).
The CSB6 provides the interface to: one PCI Bus used to connect the Radeon video controller, two LPC (Low Pin Count) Busses, used to connect to the 8MB EEPROM (holding the POST/BIOS code) and to the SIO (SuperI/O) chip. The HS40 uses a National PC87417 SIO device to provide legacy device functionality, two IDE channels supporting the internal storage options and four USB Busses for redundant connections to FDD/CDROM and Keyboard/Video.
The HS40 blade server contains four embedded Gigabit Ethernet channels, each connecting to one of the four chassis backplane connectors. The system interface is PCI-X 100 MHz, sourced by a CIOB-X2 component. Two channels are provided by two Intel Attla single-channel NIC controllers and connect to the main board interface. These controllers provide VLAN tag filtering required to support secure Serial over LAN or (SoL) functionality. The other two embedded channels are provided by a single Intel Anvik dual-channel NIC controller. These fabrics connect to the IO board backplane interface. All controllers use the Intel iSERDES interface to drive the system backplane.
In addition to the embedded Gbit Ethernet fabric controller for the network fabric connection, there are two optional secondary fabric daughter card interfaces. Each interface contains two connectors. A PCI-X 100Mhz system interface, sourced by the CIOB-X2 component, is present on one of the connectors. The other connector provides dual differential pair SERDES interfaces that are routed to each of the chassis backplane interfaces on either the main or IO board.
The daughter card approach allows for a number of secondary fabric types to be supported including FiberChannel and Ethernet. Unique daughter cards containing the appropriate PCI-X to fabric bridge circuitry are required for each fabric type.
The HS40 uses a Sahalee-based Baseboard Management Controller or (BMC) for server management support. The BMC provides access to the following functions:
Vital Product Data or (VPD) information, Field Replaceable Unit or (FRU) information, System Event Log or (SEL) information, Temperature sensors, Voltage sensors, LED control and Error reporting.
The BMC interfaces through the backplane to the Chassis Management Module over redundant RS485 interfaces. It also interfaces through the network interface via the Serial over LAN capability.

Student Notes
The BladeCenter HS40 has a local Service Processor or (SP) that provides basic environmental monitoring capabilities. It interfaces with the processor blade CPU via I2C bus, which allows In-band remote management capabilities of the processor blade within BladeCenter chassis. The Service Processor also provides out-of-band management capabilities of processor blade via RS-485 bus to the management module in BladeCenter chassis.
The service processor connects to two RS-485 interfaces on the midplane. One of the RS-485 interfaces is on the upper midplane and the other on the lower midplane. If there is only one Management Module installed in the system then the service processor on the BladeCenter HS40 will communicate with that module via the upper midplane RS-485 interface. In the future an optional management module will be available and if installed on the service processor on the BladeCenter HS40 it will communicate with whichever is the active management module.

Blade-error LED: This LED is also known as the blade system-error LED. When this amber LED is on, it indicates a system error has occurred in the blade.
Information LED: When this amber LED is on, it indicates information about a system error for this server has been placed in the BladeCenter System Error log.
Location LED: When this blue LED is on, it has been turned on in response to a programmed condition, or turned on remotely by the system administrator, to aid in blade identification for maintenance. The location LED on the BladeCenter will be on. Turn off the location LED after maintenance is complete.
Blade-activity LED: When this green LED is on, it indicates that the there is activity in the blade server, including hard disk drive use.
Power-on LED: While the BladeCenter has AC power, this green LED turns on in blinking mode and stays on when you power on your blade server. When the blade is first inserted, the LED will blink at a high frequency because the blade is being “discovered” by the Management Module at this time. As soon as the Management Module has logged the blade’s presence, it will decrease the frequency of the blinking, allowing for the power switch to function.
Media-select button: Press this button to associate the CD-ROM drive, diskette drive, and USB port with this blade server. This button lights when the ownership of the CD-ROM drive, diskette drive, and USB port transfers to this blade server.
Keyboard/mouse/video select button: Press this button to associate the keyboard, mouse, and video ports with this blade server. This button lights when the ownership of the KVM transfers to this blade server.

Answers to common positioning questions
Why Linux on Power instead of Linux on Intel?
64-bit capability
Superior price/performance in floating point
Why Power based blades instead of Opteron based blades (available from Rack Saver)
Superior price /performance with VMX
UNIX capability
IBM BladeCenter value (multiple Operating Systems with common management, etc)
Here are a few answers to common positioning questions:
Student Notes
Why Linux on Power4 processors instead of Linux on Intel?
Because there's the 64-bit capability on blades with Power4 processor, where the Intel based blades are 320bit.
Because of the superior price/performance in floating point with the JS20.
Why Power based blades instead of Opteron based blades (available from Rack Saver)?
One reason is the superior price/performance with VMX technology.
Another reason is the UNIX capability of the JS20 and IBM BladeCenter value includes multiple Operating Systems with common management.

Documentation
Hardware Maintenance Manual
Available electronically (Adobe Acrobat .PDF format) from the IBM support Web site or on the service update CD-ROM
Primary support document for diagnostics and troubleshooting
System documentation (User’s Guide, Installation Guide, etc.)
Useful for confirming shipping group contents (missing parts, etc.) and initial customer setup
Student Notes
The Hardware Maintenance Manual or (HMM) is the primary reference document for the systems covered in this course. All HMMs are now available electronically in Adobe Acrobat portable document format or (PDF). You will need Adobe Acrobat Reader, version 4 or higher, to view the contents properly, because this is the minimum supported version of the reader.
The HMM contains all the disassembly and reassembly steps, beep codes, and error descriptions to assist you in isolating a failed component.
The system documentation, which ships with every new system, may also prove useful for verifying the basic setup of the server or I/O expansion drawer. Because many of the components of modern servers are customer replaceable units or (CRUs) as well as FRUs, some setup instructions are contained in the system manuals. If you are called to a newly installed server, you will want to verify that the customer has, in fact, correctly installed everything.
