Advanced virtualization capabilities of POWER5 systems

摘要: IBM POWER5TM systems combine enhancements in the PowerPCTM processor architecture with greatly enhanced firmware to significantly increase virtualization capabilities of POWERTM servers. The POWER hypervisor, basis Virtualization EngineTM technologies on POWER5 systems, delivers leading-edge mainframe UNIX® marketplace. In addition being able create computing-intensive partitions dedicated resources (processors, memory, and I/O adapters), customers can harness idle capacity configure micropartitions virtualized order consolidate many AIXTM, i5/OSTM, Linux® servers onto a single platform. hypervisor provides support for processors, an IEEE virtual local area network (VLAN)- compatible Ethernet switch, small computer system interface (VSCSI) adapters, consoles. Many these features are dependent upon, or take advantage new facilities provided processor, including decrementer, fast page mover, simultaneous multithreading support. technology behind that available servers, enabling better utilize industry-leading computing is discussed this paper.
