SPU Information
SPU information includes the basic characteristics of the server systems
you are using in the cluster. Different servers can be mixed in the same
cluster however, they must all be running the same version of the
operating system (i.e. IA64, x86-64, etc.) This includes both uniprocessor
and multiprocessor computers.
On the worksheet, include the following items:
Server Series Number
Enter the series number, e.g., LXR2000.
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.
LAN Information
While a minimum of one LAN interface per subnet is required, at least
two LAN interfaces are needed to eliminate single points of network
failure.
It is recommended that you configure heartbeats on all subnets,
including those to be used for client data. On the worksheet, enter the
following for each LAN interface:
Subnet Name
Enter the IP address mask for the subnet. Note that
heartbeat IP addresses must be on the same subnet on
each node.
Interface Name
Enter the name of the LAN card as used by this node to
access the subnet. This name is shown by ifconfig
after you install the card.
