SPU Information
SPU information includes the basic characteristics of the systems you
are using in the cluster. Different models of computers can be mixed in
the same cluster. This configuration model also applies to HP Integrity
servers. The series 700 workstations are not supported for Serviceguard.
On one worksheet per node, include the following items:
Server Number
Enter the series number; for example, rp8400 or
rx8620-32.
Host Name
Enter the name to be used on the system as the host
name.
Memory Capacity
Enter the memory in MB.
Number of I/O slots
Indicate the number of slots.
Network Information
Serviceguard monitors LAN interfaces as well as serial lines (RS232)
configured to carry cluster heartbeat only.
NOTE Serviceguard does not support communication across routers between
nodes in the same cluster.
Serviceguard communication relies on the exchange of DLPI (Data Link
Provider Interface) traffic at the data link layer and the UDP/TCP (User
Datagram Protocol/Transmission Control Protocol) traffic at the
Transport layer between cluster nodes.
