Security Solutions

• Must be specific on device placement to allow desired access such as CNA to storage
• Allows Ethernet usage of the IRF links
Considerations
• Not considered a NSPOF configuration, IRF spans virtual fabrics
• Firmware updates are considered disruptive to both VSANs, requiring scheduled downtime.

3. Dual-redundant fabric SAN with 4-switch IRF for Ethernet—Implemented with two HP FlexFabric
5900CP switches in each fabric configured in two IRF domains for high availability and
NSPOF. See Figure 17 (page 22).
• Provides physically separate redundant fabrics with failover capabilities for high availability
with storage
• Requires four VSANs to prevent storage traffic across the IRF link
• Requires two CNAs per server or two HBAs per server
• Must be specific on device placement to allow desired access
• Allows Ethernet usage of the IRF links
Considerations
• Highly available, NSPOF configuration
• Firmware updates are considered partially disruptive, requiring fabric failover. See
“Software and Firmware update process” (page 28)
