Each PDomain has its own set of fans and I/O boards, and operates as an independent server that has full hardware isolation from other PDomains in the chassis. A hardware or software failure on one PDomain does not affect the other PDomains in the chassis. There are two redundant SPs (SP0 and SP1) in the chassis. One of the SPs functions as the Active-SP and actively manages the chassis, while the other acts as the Standby-SP that assumes the Active-SP role in the event of a failure. You can use the Oracle ILOM software that is preinstalled on each SP to remotely monitor and control PDomains.
There are two types of PDomains:
Each server can contain either two or four PDomains, in the following configurations:
All PDomains in a single server, with the two or four PDomains all contained within the single server.
PDomains split across two servers, with one of these situations:
Two PDomains are split across the two servers (one PDomain on each server)
Four PDomains are split across the two servers (two PDomains on each server)
