Using Mount Points in Hyper-V
Failover Clustering in Windows Server 2008 allows a single cluster with up to
16 nodes. Therefore, you can have a single Hyper-V Host Cluster
configuration across up to 16 servers. As shown in Figure B-1, one of the most
common mechanisms to provision virtual disks to virtual machines is via
VHD files created on a formatted volume on a storage disk mounted in the
parent partition with a drive letter.
Figure B-1. Typical VHD Configuration on Storage Disk Assigned with a Drive Letter
In a Hyper-V Host Cluster configuration with many servers that host a large
number of VHD-based virtual machines, there may not be sufficient number
of drive letters (A-Z) in the parent partition to host the storage LUNs. To
work around this drive letter limitation, Hyper-V allows the use of Mount
Points to host storage LUNs.
