Post-Installation Configuration
Pre-Installation
Verify that aggregate subnet throughput supports IP traffic
Verify that the throughput of each host is documented
Verify that cluster members support client throughput
Verify that all IP addresses are manually allocated
Verify that TCP/IP is bound to the network card
Hardware Considerations
No special hardware requirements
Ethernet or FDDI
All hosts on one broadcast subnet
All host on one Level 2 switch or VLAN
All hosts on a single hub or repeater
Two NICs per host preferred:
One NIC for cluster traffic and heartbeats
One NIC for replications/backend access
Controlling Switch Flooding
Hosts on individual ports results in switch flooding
Hosts on a hub limits switch flooding
