Hi
We are installing a SQL Server 2008 R2 Active/Active cluster on W2K8 R2, with one instance on each of the two nodes (for now). Every node has a local C: and D: disk, while we have several SAN LUNS available for use within the SQL Server resource groups.
What are the recommended disks for installing the "instance root directories" and "shared feature folders" on? Should either of these be installed on shared SAN LUNS or are they supposed to be installed on the local disks of each node (i.e. D:)? Maybe both options are possible with their own advantages and drawbacks, considering the fact that multiple instances per node will soon be installed?
Thanks for any suggestions.
