Hyper-V Server 2012 Release Candidate surfaces at TechEd

A free download is available on Microsoft’s website for those who want to experiment with the new, free version of Hyper-V.

Hyper-V Server is offered as a standalone product by Microsoft apart from the Windows Server OS. As such, Microsoft recommends it for use among “organizations who want to consolidate on a single physical server or have low utilization infrastructure workloads, departmental applications, and branch office workloads.” Other recommended uses include test / development and VDI.

Given the limited scenarios for Hyper-V Server, some Microsoft TechEd attendees at this week’s conference said they’ll hold out for the full-fledged release.

“The only reason I would use [Hyper-V Server] would be for VDI or Linux,” said Nathaniel Avery, senior solutions architect at ActioNet in Washington DC. “But even then, with VDI, it’s a maybe, because then I’d be running multiple versions of Hyper-V in the same environment.”

The freebie hypervisor includes all the features of the Windows Server 2012 Release Candidate Hyper-V, which became available on May 31. The major update in the Release Candidate is greater scalability than was offered in the developer preview made available at the Build conference last year and the beta release out earlier this year.

Resource capacities per host have doubled with the Release Candidate — logical processors supported per host have gone from 160 to 320; physical memory from 2 to 4 TB; and virtual CPUs from 1024 to 2048. Virtual CPUs supported per VM have also doubled from 32 to 64.
