What Your Ibm Xseries 380 Offers - IBM eServer 380 xSeries User Reference Manual

What your IBM xSeries 380 offers

The unique design of your server combines the following features:
•
•
•
Multiprocessing performance
Your system supports one to four Itanium microprocessors with either 2 or 4 MB
each of level-2 cache. It is a four-way symmetric mutliprocessing (SMP) server.
Large system memory
The xSeries 380 can support up to 64 GB of system memory. Memory resides on
two memory boards. Each memory board contains slots for 32 dual inline memory
modules (DIMMs). The memory controller supports PC100-registered version 1.2
buffered synchronous dynamic random access memory
Supported DIMM sizes are 256 MB, 512 MB, and 1 GB. Each memory board can
support from 1 GB to 32 GB.
System-management capabilities
Three controllers provide the system-management capabilities of your server: the
Baseboard Management Controller (BMC), Intelligent Chassis Management Bus
Controller (ICMBC), and the Hot-Swap Controller (HSC).The BMC monitors for
system platform management events and logs their occurrence in the System
Event Log (SEL). System platform management events include over-temperature
and over-voltage conditions as well as fan failures.
The HSC performs the SAF-TE command set, controls the fault lights, and
provides a path for management information from the SCSI interface. It retrieves
drive fault status, backplane temperature, and fan failure information from the
Intelligent Platform Management Bus (IPMB). Then, it queries the status of the
power distribution board from the BMC and controls drive power-on and power-
down. This facilitates the hot-swapping capabilities of the PCI adapters, fans, and
hard disk drives.
The Chassis Bridge Controller (CBC) serves as a bridge between the internal
Intelligent Platform Management Bus (IPMB) and the external Intelligent Chassis
Management Bus Controller (ICMBC). The internal IPMB transports management
information within a system, and the external ICMBC transports server
management information between the servers.
