Dual domain — best performance cabling

This example illustrates cabling for a dual-domain configuration in a pattern that offers best possible

performance. In this configuration, note the following:

• A multi-port, dual-domain controller in the host and dual-port disk drives in the disk enclosure are

required for dual-domain deployments.

• Cables from each I/O module in the disk enclosure to the server or controller enclosure and to

additional cascaded disk enclosures provide dual-domain connectivity.

• The symmetrical cabling pattern lowers latency and provides best possible performance.

• This example illustrates using a Small Form Factor disk enclosure with one additional cascaded

disk enclosure. When using Large Form Factor disk enclosures, more than one additional disk

enclosure can be cascaded. For more information, see the QuickSpecs for the Large Form Factor

disk enclosure.
