Preparing Your Systems for Clustering 29
A WWN is a unique numeric identifier assigned to Fibre Channel interfaces,
such as HBA ports, storage controller ports, and Fibre Channel to SCSI
bridges or storage network controllers (SNCs).
A WWN consists of an 8-byte hexadecimal number with each byte separated
by a colon. For example, 10:00:00:60:69:00:00:8a is a valid WWN. WWN
port name zoning allows you to move cables between switch ports within the
fabric without having to update the zones.
Single Initiator Zoning
Each host HBA port in a SAN must be configured in a separate zone on the
switch with all the Compellent front-end virtual ports. This zoning
configuration, known as single initiator zoning, prevents different hosts from
communicating with each other. This ensures that Fibre Channel
communications between the HBAs and their target storage systems do not
affect each other.
Follow these guidelines when you create single-initiator zones:
• Create a zone for each HBA port, all the Compellent front-end virtual
ports, and the integrated bridge/SNC or fibre-channel interface on a tape
library.
• Create a zone with only the Compellent physical WWNs.
Installing and Configuring the Shared Storage
System
This section describes how to install and configure the Compellent storage
system in your cluster. The procedures, especially how to initialize or set up
the controllers, provide a high-level description of the tasks. For more
information, see the Storage Center System Manager Setup Guide and Storage
Center System Manager User Guide. If you need support assistance, contact
Dell Technical Support Services at support.dell.com/compellent.
NOTE: All hardware must be installed and cabled before you begin the setup and
software installation process. The Fibre Channel switches must be configured and
zoned before the controllers are set up.
