Dynamic Logical Partitioning for Linux on POWER

Posted by Hemos on from the learn-how-to-do-more dept.

An anonymous reader writes "Logical partitioning provides POWER processor-based servers with the capability to do server consolidation and optimize system resources. Dynamic logical partitioning enhances this capability by providing control of the allocation of the resources without impacting the logical partitions availability. Linux on POWER supports dynamic LPAR for changes to physical I/O, virtual I/O, and processor resources."

    And for once I drool over something I have only vaguely an idea of what it does.

    What it does is allow reconfiguration of system resources, such as IO cards, memory or cpu's (or on Power 5 with AIX 5.3, portions of a cpu), etc. on the fly without having to reboot your server to acknowledge them. AIX has had this capability since 5.2.

    It's great for being able to juggle your resources on the fly, but it really comes in handy for moving your DVD drive between partitions on a frame without having to reboot. Having to reboot 2 servers just for that is a royal PITA.
