Windows Cluster ve Hyper-v Limitleri

The following table lists the requirements and maximums that apply to the server running Hyper-V. In addition, we recommend that you review the Windows Catalog to identify servers that are qualified for use with Hyper-V. You can identify systems that support the x64 architecture and Hyper-V by searching the Windows Server catalog. For Windows Server 2008 you can select Hyper-V as an additional qualification (see http://go.microsoft.com/fwlink/?LinkId=111228). For Windows Server 2008 R2, all systems that have a “Certified for Windows® Server 2008 R2” logo support Hyper-V.

Component	Maximum	Notes
Logical processors	64	Both of the following must be available and enabled in the BIOS: Hardware-assisted virtualization Hardware-enforced Data Execution Prevention (DEP)
Virtual processors per logical processor	12 with conditions met in the ‘Notes’ column, otherwise 8.	A ratio of 12:1 is supported on Hyper-V in Windows Server 2008 R2 Service Pack 1 when all guest operating systems on the server run Windows 7. Otherwise, the supported ratio is 8:1.
Virtual machines per server	384 running virtual machines	None.
Virtual processors per server	512	None.
Memory	1 TB	None.
Storage	Limited by what is supported by the management operating system. No limits imposed by Hyper-V.	For more information about the storage options for Hyper-V, see Planning for Disks and Storage. For general information about storage for Windows Server, see Reviewing Storage Limits(http://go.microsoft.com/fwlink/?LinkID=161361). Note Microsoft does not support network-attached storage (NAS) for Hyper-V.
Physical network adapters	No limits imposed by Hyper-V.	None.
Virtual networks (switches)	Varies; no limits imposed by Hyper-V.	The practical limit depends on the available computing resources.
Virtual network switch ports per server	Varies; no limits imposed by Hyper-V.	The practical limit depends on the available computing resources.

The following table lists the maximums that apply to highly available servers running Hyper-V. It is important to do capacity planning to ensure that there will be enough hardware resources to run all the virtual machines in a clustered environment. For more information about requirements for failover clusters and Hyper-V, see Hyper-V: Using Hyper-V and Failover Clustering (http://go.microsoft.com/fwlink/?LinkID=129063).
