The illustration that follows shows a VCS campus cluster configuration of disks. For campus clusters, each disk group must contain an equal number of disks on each site. This example has one disk group that spans the storage arrays at both sites.
The data and database log on Site A are mirrored to Site B. Each volume should be a mirrored volume with one plex of the volume on Site A's storage array and the other plex of the volume on Site B's storage array.
Note: |
Each mirrored volume does not need to be limited to two disks, but can have four disks for greater resiliency. |
All the data on one site could be in one large mirrored volume with multiple disks, but this also requires the same number of disks on both sites for the mirroring. It is recommended that the log volumes be on separate disks from the data.
