When configuring switches in a fabric, optimize the fabric performance based on the most significant expected use. NOTES: Except for unique identifiers such as the switch name, domain name, and IP address, all switches in a fabric must have the same firmware configuration. Switches that are configured differently are isolated from the fabric. Live switches may be cascaded; however, the domain IDs must be different. If the domain IDs of any of the switches are identical, the fabric will segment and a fabric segment error will be reported. This problem can be resolved by rebooting one of the switches with a conflicting domain ID. PowerVault 51F and higher switches run on version 2.0 of the software only. To be compatible with the PowerVault 50F software, these switches must be configured using VC Encoded Address Mode, which limits the switch count in a fabric to 32 and the number of multicast groups to 31. Refer to your switch's Installation and Troubleshooting Guide for more information. Cascaded topologies using multiple switches give switching system designers a powerful, flexible set of resources to create a high-performance, robust storage area network (SAN) or data center backbone. A new fabric contains no zone configuration information. When you connect a new fabric to an existing zoned fabric, all switches in the new fabric inherit the zone configuration data. If a zone configuration is enabled, the same configuration becomes enabled in the new switches. After this operation, the cfgShow command displays the same output on all switches in the joined fabric, including the new switches. support.dell.com NOTE: To modify a zoned fabric, Dell recommends that you never change an existing zone, but rather replace it with a newly configured zone. 1. Map out the desired fabric changes. See Figure 1-1 in Chapter 1, "Introduction," for an example of a zoned fabric. 2. Define the new core aliases. 3. Delete the unwanted core aliases. 4. Define the new zones. 5. Delete the unwanted (old) zones. 6. Save the configuration. NOTE: Dell recommends that you save a new configuration under a different name than the currently enabled configuration so that your current configuration will remain available in case the new configuration fails.
