Hardware Requirements

Servers - Servers should be configured in accordance with the requirements described in the LifeKeeper for Linux Technical Documentation and the LifeKeeper Release Notes.

IP Network Interface Cards - Each server requires at least one Ethernet TCP/IP-supported network interface card. Remember, however, that best practice is for a LifeKeeper cluster to have at least two communication paths. Two separate LAN-based communication paths using dual independent sub-nets are recommended for heartbeats, and at least one of these should be configured as a private network. Using a combination of TCP and TTY heartbeats is also supported.
