1 Introduction The HP Integrity Superdome 2 servers (HP Superdome 2) are scalable systems based on blade system architecture. HP Superdome 2 systems support HP nPartitions and HP-UX Virtual Partitions (vPars). This administrator guide describes the steps to plan, create, and manage partitions - - HP Integrity Superdome 2 16-socket | HP Superdome 2 Partitioning Administrator G - Page 12

A socket on HP Superdome 2 represents the Field Replacable processing unit on a blade. Each socket presents 4 CPU-cores.

In HP Superdome 2 systems, you can assign CPU cores, memory (interleaved (ILM) and socket local ( supports the following virtual partition commands - vparcreate, vparmodify, vparremove, vparboot, vparreset, and vparstatus.

OA at the OA prompt. On the OS side, the Partition commands executed from the HP-UX shell are logged to the local syslog file (the syslog file of the partition was executed). Log File Location and Log Format The default syslog file on HP-UX systems is/var/adm/syslog/syslog.log.

Virtual Partitions Licensing On HP Integrity Superdome 2 servers, the HP-UX Virtual Partitions (vPars) product which enables managing vPars from HP-UX is sold on a per-socket licensing basis. Therefore, you purchase the same quantity of this product as - HP Integrity Superdome 2 16-socket | HP Superdome 2 Partitioning Administrator G - Page 17
NOTE: HP Integrity servers running the new HP sx3000 chipset are quad core (4 cores per processor/ per socket), but HP-UX licensing is per-socket or per processor. Therefore, one per-socket software license is required per each quad-core processor.
