Martin,

Can you give some more examples of those HA features for SuSE Linux ?
I know about "OpenMosix" !
What other software can be used to cluster Linux Pc's ?

Tx in advance,
Yves

DRDB is a _very_ bad recommendation for a production system. DRDB is
unreliable by any definition.

Simply make up the potential fault matrix and you will notice that DRDB
will
not provide the safety expected from a failover cluster.

Depending on the kind of applications employed there are many HA features
available on SuSE Linux.
