Manageability Subsystem; Server Blades; Server Blades And Partitions; I/O Subsystem - HP Integrity Superdome 2 16-socket Service Manual

Superdome 2 IOX enclosures support two ac power supplies with a minimum of one power supply
required to provide all necessary power to the enclosure and two power supplies providing 2N
redundancy.

Manageability subsystem

Superdome 2 is managed by two Superdome 2 OAs that monitor both individual complex
components and complex health. This information can be accessed one of two ways:
A GUI using a remote terminal.
A CLI using a remote or local terminal.
NOTE: Only one OA is required for operation, the second OA provides redundancy and automatic
failover capabilities.
Two GPSMs in each compute enclosure manage CAMnet distribution to all server blades, XFMs
and IOX enclosures in the complex and provide the redundant global clock source for the complex.
Fans and power supplies in the upper section of the compute enclosure are monitored and controlled
by the OA through the GPSMs. Also, the GPSMs provide power for the rack door display as well
as USB connectivity for the compute enclosure DVD module.
Each compute enclosure supports four XFMs that provide the Superdome 2 crossbar fabric, which
carries blade-to-blade (within an enclosure and between enclosures in a complex) and blade-to-IOX
data transfer packets.

Server blades

HP Integrity Superdome 2 CB900s i2 Server Blades support two Quad-Core Intel Itanium 9300
series processor modules and up to 32 DDR3 DIMMs.
HP Integrity Superdome 2 CB900s i4 Server Blades support two Eight-Core Intel Itanium 9500
series processor modules and up to 32 DDR3 DIMMs.

Server blades and partitions

An nPartition comprises one or more server blades working as a single system. I/O bays in IOX
enclosures are assigned to nPartitions and any I/O component of a server blade such as LOMs
are assigned to the nPartition containing the server blade.
In the complex, each nPartition has its own dedicated portion of the complex hardware, which
can run a single instance of an operating system. Each nPartition can boot, reboot, and operate
independently of any other nPartitions and hardware within the same complex.
An nPartition includes all hardware assigned to the nPartition: all IOX I/O bays, I/O devices, and
server blades.
A complex can contain one or more nPartitions, enabling the hardware to function as a single
system or as multiple systems.
NOTE: For more information, see the HP Integrity Superdome 2 Partitioning Administrator Guide.

I/O subsystem

HP Integrity Superdome 2 complexes provides I/O through PCIe devices based on individual server
blades as well as through IOX enclosures that are connected to the complex.

Server blade-based I/O

Each Superdome 2 server blade contains two dual port 10Gb Ethernet LOMs. Connectivity to the
LOMs is provided through the interconnect modules in the rear of the compute enclosure.
