A Gauntlet Of Older Gear

摘要

Straight hypervisor performance doesn't reflectrnthe entire cluster management-performance experience. This Rolling Review was, first and foremost, a qualitative assessment so we built our test bed to gauge each product's setup, physical-to-virtual conversions, and day-to-day manageability.rnWe ran all five platforms on a variety of server hardware, then put all of the virtualization suites except Parallels through a final series of tests on identical hardware.The test cluster included four quad-core Hewlett-Packard DL385-G2 servers, two configured with 12 GB of RAM and two configured with 8 GB of RAM. Within each, host hypervisors were installed on a pair of hardware-RAID mirrored 72-GB 10,000-rpm SAS drives. VMware,Citrix, and Virtual Iron installations were bare metal, and Microsoft Hyper-V was installed on top of Windows 2008.
