Deployment Guide
Fibre Channel Zoning
When using Fibre Channel for front-end connectivity, zones must be established to ensure that storage is visible to the servers. Use
the zoning concepts discussed in this section to plan the front-end connectivity before starting to cable the
storage system.
Dell recommends creating zones using a single initiator host port and multiple Storage Center ports.
WWN Zoning Guidelines
When WWN zoning is configured, a device may reside on any port, or change physical ports and still be visible, because the switch is
seeking a WWN.
List of guidelines for WWN zoning.
• Include all Storage Center virtual World Wide Port Names (WWPNs) in a single zone.
• Include all Storage Center physical World Wide Port Names (WWPNs) in a single zone.
• For each host server HBA port, create a zone that includes the HBA port WWPN and multiple Storage Center virtual WWPNs
on the same switch.
• For Fibre Channel replication from Storage Center system A to Storage Center system B:
– Include all Storage Center physical WWPNs from system A and system B in a single zone.
– Include all Storage Center physical WWPNs of system A and the virtual WWPNs of system B on the particular fabric.
– Include all Storage Center physical WWPNs of system B and the virtual WWPNs of system A on the particular fabric.
NOTE: Some ports may not be used or dedicated for replication, however ports that are used must be in these
zones.
Labeling the Front-End Cables
Label the front-end cables to indicate the storage controller and port to which they are connected.
Prerequisites
Locate the front-end cable labels that shipped with the storage system.
About this task
Apply cable labels to both ends of each cable that connects a storage controller to a front-end fabric or network, or directly to host
servers.
Steps
1. Starting with the top edge of the label, attach the label to the cable near the connector.
Figure 38. Attach Label to Cable
2. Wrap the label around the cable until it fully encircles the cable. The bottom of each label is clear so that it does not obscure
the text.
