This server has a pair of redundant SPs (SP0 and SP1). One of the SPs functions as the Active-SP to manage the platform, and the other acts as a Standby-SP that will assume the Active-SP role in the event of a failure.
Both SPs are individually accessible from the external network, so they need to be configured separately with unique IP addresses. As part of failover, the IP address assigned to an Active-SP migrates to the new Active-SP, depending on which SP is controlling the chassis. To enable you to connect to this IP address to manage the chassis, instead of accessing SP0 or SP1 separately, you must configure the IP address for the Active SP.
In addition, the server is capable of supporting up to four PDomains. One of the SPPs on each PDomain is identified as a PDomain-SPP, and it is responsible for managing tasks for the PDomain and hosting the rKVMS service for the PDomain. To enable rKVMS access to a PDomain, you need to configure the SPP network settings for that PDomain. PDomain-SPPs are also accessible from the external network, as long as you have configured IP addresses for them.
