4. Dual-redundant storage fabric configuration with two stacked switches
in IRF domains—Implemented with two HP FlexFabric 5900CP switches in each fabric
configured in two IRF domains for high availability and NSPOF. See Figure 18 (page 23).
• Avoid irf-port congestion by using multiple 40G connections
• Only one VSAN per IRF domain required
• No specific device connectivity to maintain NSPOF
• When storage is connected to switches utilizing IRF, add the following command to the
configuration file: fspf graceful-restart
• Firmware updates are considered partially disruptive, requiring fabric failover. See
“Software and Firmware update process” (page 28)
• This configuration leverages IRF as a stacking interconnect with one VSAN per IRF domain
and includes FCoE QOS configuration of stacked irf-ports. Enable FCoE priority 3
priority-flow-control on irf-ports.
Examples:
irf-port 1/1
port group interface FortyGigE1/0/49
priority-flow-control auto
priority-flow-control no-drop dot1p3
irf-port 2/1
port group interface FortyGigE2/0/49
interface FortyGigE2/0/49
priority-flow-control auto
priority-flow-control no-drop dot1p3
