Best Practices for Virtualizing and Managing Exchange 2013

Figure 23: Cluster Shared Volumes

Best Practices and Recommendations

To provide high availability, use at least one separate CSV for Exchange 2013 databases/logs so

that each mailbox database copy of a particular mailbox database is stored on separate

infrastructure. In other words, in a four-copy deployment, a minimum of four CSVs should be used

to isolate database copies, and the storage and networking infrastructure used to provide access

to those CSVs should be completely isolated, as well.

The following guidelines are recommended for deploying a SAN with a failover cluster:

 Confirm with the manufacturers and vendors whether the storage (including drivers,

firmware, and software) being used is compatible with failover clusters in Windows Server

2012. The Windows Server Catalog can be a useful source of guidance for this

information.

 Isolate the LUN used for one set of cluster servers from all other servers through LUN

masking or zoning.

 Use multipath I/O software for the highest level of redundancy and availability when

connecting your hosts to iSCSI or FC storage.
