Two HP Multi-Function Adapters Configured to Provide
Both High Availability and Best Performance
NOTE
The following recommendations assume that your systems are also
configured with failover software such as HP Serviceguard and Logical
Volume Manager. Consult docs.hp.com for full details on configuring your
products for high availability.
—
Use only 1 port on each of two adapters as the “primary” port for that technology’s
normal data traffic. The second port on the same adapter becomes an “alternate” or
hot-standby for the other adapter.
—
Connect the Fibre Channel port from each of the two adapters to a different storage
area network (SAN) by connecting through different FC switches--which then connect
to different ports on the mass storage device. Failover between the two paths is
managed by logical volume manager (LVM) PVLinks (for alternate paths) or
SecurePath.
—
Connect each GigE port through a different network switch and ensure that the
switches are bridged to the same IP subnet. Failover between the two network paths
is managed by Serviceguard’s local network failover capability.
—
Connect the built-in network ports on multiple rp8400s to a private subnet and use
them for a dedicated heartbeat for Serviceguard.
This configuration protects you from a failure of the FC port on either adapter, a failure
of either FC switch, the failure of either controller on the mass storage device or any
single FC cable failure. It also protects you from the failure of the GigE network port on
either adapter, a failure of either network switch, or the failure of any single network
cable.
