Re: suggestions re. cluster configuration

For a two node HA cluster, I think the simplest way would be heartbeat and
DRBD. That would give you a single service IP address and data mirroring. In
my experience with this config, you can get failover in just a few seconds
if the primary node dies. There are lots of ways to make it more complex...
Xen, etc., but that might just be making it harder than it needs to be.

Subject: [SSI-users] suggestions re. cluster configuration

Hi,

I'm wrestling with possible configurations for a 2-node, high availability
cluster.

What I seem to be zeroing in on is:
- using Xen to provide several virtual servers on each box
- using md to raid together the disks on each server
- using DRBD to mirror the primary machine to the backup server
- using EVMS to manage partitions and such
- using SSI to provide a single interface to the world for each pair of
virtual servers

Anybody have any experience with this kind of setup? Any suggestions,
pointers to recipes, etc.?

Thanks much,

Miles Fidelman
