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, including LOMs and mezzanine cards 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 provide I/O through 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. For more information, see the HP Integrity Superdome 2 User Service Guide. I/O expansion enclosure HP Integrity Superdome 2 complexes support up to eight IOX enclosures (four in SD2-8s complexes) to provide additional I/O for server blades through Flex-connect cables from the XFMs in the compute enclosure to IOX enclosures. In addition, CAMnet manageability fabric is provided through CAMnet cables from the GPSMs to the IOX enclosures. An IOX contains two I/O bays each supporting up to six PCIe cards (for a total of 12 PCIe cards per IOX). I/O bays are assigned to an nPartition dynamically through the partitioning tools that reside on the OA. I/O subsystem 7

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, including LOMs
and mezzanine cards 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.

I/O subsystem
HP Integrity Superdome 2 complexes provide I/O through 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.
For more information, see the
HP Integrity Superdome 2 User Service Guide
.
I/O expansion enclosure
HP Integrity Superdome 2 complexes support up to eight IOX enclosures (four in SD2-8s
complexes) to provide additional I/O for server blades through Flex-connect cables from the
XFMs in the compute enclosure to IOX enclosures. In addition, CAMnet manageability fabric is
provided through CAMnet cables from the GPSMs to the IOX enclosures. An IOX contains two
I/O bays each supporting up to six PCIe cards (for a total of 12 PCIe cards per IOX). I/O bays are
assigned to an nPartition dynamically through the partitioning tools that reside on the OA.
