HyperFabric Configuration Guidelines
TCP/UDP/IP
If any HyperFabric resource in a cluster fails (adapter card, cable or
switch port), the HyperFabric driver transparently routes traffic over
other available HyperFabric resources with no disruption of service.
The ability of the HyperFabric driver to transparently fail over
traffic reduces the complexity of configuring highly available clusters
with ServiceGuard, because ServiceGuard only has to take care of
node and service failover only.
ServiceGuard uses a “heartbeat” to monitor the cluster. The
HyperFabric links cannot be used for the heartbeat. Instead, an
alternate LAN connection such as 100BaseT, Ethernet, Token Ring,
and FDDI must be made between the nodes for use as a heartbeat
link.
End-To-End HA: HyperFabric provides End-to-End HA on the
entire cluster fabric at the link level. If any of the available routes in
the fabric fails, HyperFabric transparently redirects all traffic to a
functional route and, if configured, notifies ServiceGuard or other
enterprise management tools.
Active-Active HA: In configurations where there are multiple
routes between nodes, the HyperFabric software uses a hashing
function to determine an adapter or a route through which it sends
messages. This is done on a message-by-message basis. All of the
available HyperFabric resources in the fabric are used for
communication.
In contrast to Active-Passive HA, where one set of resources is not
utilized until another set fails, Active-Active HA provides the best
return on investment because all of the resources are utilized
simultaneously. ServiceGuard is not required for Active-Active HA
operation.

clusters, see Installing and Administering HyperFabric Part Number

Dynamic Resource Utilization (DRU): Supported
If you add a new resource (node, adapter, cable or switch) to a
cluster, the HyperFabric subsystem dynamically identifies the added
resource and start using it. The same process takes place when a
