In addition to “ live migration, clustered shared volumes, hot add/remove of storage and improved networking support,” Microsoft announced “64 logical processor support and processor compatibility mode for live migration!” for Hyper-V (download) in Windows Server 2008 R2 (download). “We have seen processors grow from 1, 2, 4, and now 6 cores on a single processor, soon to hit 8. Within the Windows Server 2008 R2 lifecycle, 64 logical processor servers will become commonplace (8 processors x 8 cores). Virtualization is the natural fit for these next-gen servers, allowing them to consolidate a greater number of virtual machines on a single host. Hyper-V is in line with these hardware trends all with an eye towards bringing you greater VM density,” said Isaac.
