Cabling Several Racks Together

By using the following procedures, you can add another rack to an existing multi-rack system.

The procedures assume that the racks are adjacent to each other. The existing racks are R1, R2, ... Rn, and the new rack is Rn+1. For example, if you have four racks and you are adding a fifth rack, the existing racks are designated R1, R2, R3, and R4 and the new rack is designated R5.

Starting with Recovery Appliance RA21 models, you can cable up to 12 racks together without additional switches. For prior models (up to X8M), you can cable up to 18 racks together without additional switches.

The procedures differ for systems that use RoCE Network Fabric (X8M and later) and InfiniBand Network Fabric (X8 and earlier).
