PowerVault™ MD32X0, MD32X0i, and MD36X0i Series of Storage Arrays: Implementing Hyper-V
MD32X0-specific cluster requirements:
•
Only use two dual-ported SAS adapters for each server, and connect one port of each
adapter to the MD3200 storage array in clustered environments to achieve the highest
level of redundancy.
MD32X0i-specific and MD36X0-specific cluster requirements:
•
The storage configuration must be redundant. Only use two or more network
connections for iSCSI traffic to the MD32X0i or MD36X0i storage array.
•
Use dedicated iSCSI network adapters for iSCSI environments. You cannot share
communication and iSCSI traffic on the same adapter in clustered configurations.
All cluster-nodes must be able to communicate with the same virtual disks on the MD32X0, MD32X0i, or
MD36X0i storage array. You can use storage partitioning to create a server group with the cluster-nodes
and assign the necessary virtual disk to them. Make sure that only the cluster -nodes have access to
those virtual disks. Make sure that other servers do not have access to those virtual disks.
When planning, create an additional virtual disk for the quorum disk. Make this virtual disk at least 1
GB in size. This disk contains the quorum information and is used as the witness disk. Format the
quorum virtual disk with NTFS. More details on creating a quorum disk are described in the next
section.
