In our test environment, a second instance of SQL Server 2008 is used to store half of the SharePoint

content databases. By dividing the SharePoint farm into independent web applications, a second DR

group can be created that allows even balancing of the application workload across both the storage

controllers. Using two DR groups provides a second bidirectional replication path, which improves the

SharePoint application and replication performance.

Use Command View EVA management software to create the DR groups with only a few clicks.

Figure 4 shows a DR group being created using Command View EVA.

Figure 4. Create a DR group

As part of the DR group creation process, the first virtual disk is added to the DR group. Therefore, it

is best to create the disk groups on the destination array, mimicking the source environment, before

creating the DR group. Then, as members are added to the DR group, the appropriate destination

disk group can be selected.

During creation of the DR group, most options are self-explanatory, such as selecting the source and

destination arrays. Options for the write mode, failsafe mode, and replication log are discussed

below.
