Installing and Configuring Interconnect, Storage, and Fibre Channel Hardware

Generally, using interconnect, storage, and Fibre Channel (FC) hardware does not differ markedly from standard cluster configurations.

The steps for installing Ethernet-based campus cluster interconnect hardware are the same as the steps for standard clusters. Refer to Installing Ethernet or InfiniBand Cluster Interconnect Hardware. When installing the media converters, consult the accompanying documentation, including requirements for fiber connections.

The guidelines for installing virtual local area networks interconnect networks are the same as the guidelines for standard clusters. See Configuring VLANs as Private Interconnect Networks.

The steps for installing shared storage are the same as the steps for standard clusters. Refer to the documentation for your storage device for those steps.

Campus clusters require FC switches to mediate between multimode and single-mode fibers. The steps for configuring the settings on the FC switches are very similar to the steps for standard clusters.

If your switch supports flexibility in the buffer allocation mechanism, (for example the QLogic switch with donor ports), make certain you allocate a sufficient number of buffers to the ports that are dedicated to interswitch links (ISLs). If your switch has a fixed number of frame buffers (or buffer credits) per port, you do not have this flexibility.

Calculating Buffer Credits

The following rules determine the number of buffers that you might need:

For greater speeds or for more details, refer to your switch documentation for information about computing buffer credits.
