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

.
•
Provides physically separate redundant fabrics with failover capabilities for high availability
with storage
•
Requires four VSANs to prevent storage traffic across the IRF link
•
Must be specific on device placement to allow desired access
•
Allows Ethernet usage of the IRF links
