FAQ

===============================

Q: Why is the maximum memory different for Windows Server 2008 R2 depending on whether the Hyper-V role is enabled or not?

A: System availability. Servers with 512 GB, 1 TB or more don’t just grow on trees. J Thus, Hyper-V has a supported limit of 1 TB.

------------------------------------------------------------------------------------------------------------

Q: Will the maximum amount of memory of Windows Server with Hyper-V be raised?

A:  Keep in mind that whether it’s the maximum amount of memory supported or number of processors supported, scalability is an ongoing development activity at Microsoft.

Considering the limited number of servers that support such large memory footprints and the high cost associated with populating a server with >1 TB, we believe we have an excellent solution with Windows Server 2008 R2 Hyper-V today.
