virtual I/O server overview

What is Advanced POWER Virtualization (APV)
APV – the hardware feature code for POWER5 servers that enables:– Micro-partitioning – fractional CPU entitlements from a shared pool ofprocessors, beginning at one-tenth of a CPU– Partition Load Manager (PLM) – a policy-based, dynamic CPU andmemory reallocation tool– Physical disks can be shared as virtual disks to client partitions– Shared Ethernet Adapter (SEA) – A physical adapter or EtherChannel ina VIO Server can be shared by client partitions. Clients use virtualEthernet adapters
Virtual Ethernet – a LPAR-to-LPAR Virtual LAN within a POWER5 Server– Does not require the APV feature code
