SAN scaling
When you expand a topology, avoid making changes that disrupt the original design goals. If
data access requirements have changed, consider migrating to a topology that meets the current
needs.
A high-availability SAN design accommodates a nondisruptive expansion. See “SAN fabric
topologies” (page 23).
CAUTION: HP highly recommends that you stop all I/O activity and back up all data before
adding switches to the fabric.
To expand a SAN:
• Use switches with a higher port count.
• Increase the number of switches.
To add switches to an existing fabric, ensure that the new configuration conforms to fabric
rules. See the following fabric rules sections:
◦ “Fabric rules” (page 144), for H-series switches
◦ “Fibre Channel switch fabric rules” (page 102), for B-series switches
◦ “Fibre Channel switch fabric rules” (page 135), for C-series switches
• Add another fabric as a high-availability NSPOF solution.
• Implement Fibre Channel routing. See “Fibre Channel routing” (page 43).
• Deploy multiple independent SANs.
• Migrate to a different SAN topology. See “Topology migration” (page 41).
When adding new switches, avoid fabric segmentation. For more information, see “Fabric
segmentation errors” (page 403).
Cascaded fabric expansion
Expand a cascaded fabric by connecting a new switch to an available port on an existing switch.
If no ports are available, remove devices from an existing switch, connect the new switch to those
ports, and then reconnect the devices to the new switch.
Meshed fabric expansion
Expand a meshed fabric by connecting a new switch to available ports on an existing switch. If
no ports are available, remove devices from an existing switch, connect the new switch to those
ports, and then reconnect the devices to the new switch. Ensure that multiple paths (ISLs) connect
the new switch to the meshed fabric.
