Chipset And Crossbar Switch; Server Management - NEC Express5800 1160Xd User Manual

Each partition is physically isolated by the hardware settings; a software error does not
affect the other partitions. Thus the system can maintain high security.
Each partition consists of a Cell Board and a core PCIX unit. Multiple OS instances can
run on different partitions independently. If a partition has at least one PCIX unit with
basic I/O, the Cell Boards and the PCIX units can be flexibly assigned to any partition.
Even if a failure occurs in a Cell Board, the system can disable the failed Cell Board
and reboot the partition by reassigning a spare Cell Board. This feature minimizes
partition down time.
The Service Processor manages the partitioning settings and configuration changes.
You can change the partition configuration in the main cabinet by using the CC
command in the SP command mode (see Chapter 3).

Chipset and Crossbar Switch

NEC developed a high-performance chipset and crossbar switch that is based on
supercomputer mainframe technology. The crossbar switch connects the Cell Boards
The crossbar switch has a low latency as well as high data bandwidth. While
comprising Cache Coherent Non-Uniform Memory Access (cc-NUMA) architecture,
the system employs the chipset and crossbar switch technology in achieving near
uniform high-speed memory access.

Server Management

The Service Processor supports many management functions compatible to the
Advanced Configuration and Power Interface (ACPI) and Intelligent Platform
Management Interface (IPMI).
The system supports the following ACPI features:
!
Configuration information tables interface from a platform.
!
Software power off controls, etc.
The Service Processor also works as a management controller defined in IPMI. It
supports the following IPMI features.
!
Provides Field Replaceable Unit (FRU) information to System Management
Services (SMS) running on the operating system.
!
Monitors system power, fan speed, and temperature conditions.
!
Monitors stall occurrences during the power-up sequence, OS loading, and
normal running using a watchdog timer, etc.
The Service Processor provides the following management features:
!
Error handling (error monitoring, logging, diagnostics, and reporting)
!
System reset
!
System configuration management
!
Firmware update, etc.
