Scaling

My SMB database is currently running on a HP-UX box running in a master -
slave slonyI cluster to create a hot spare database. Recently the server has
be getting hammered and we are consistently hitting our max db connections.
We have our web CMS and our web apps, our desktop client apps, and a couple
application servers running off of this database server and it is crumbling
under the stress. Currently we have been doing table partitioning and table
archiving to trim the fat off of the indexing processes etc.

My project at hand is to upgrade this configuration to a linux cluster of
servers, 2 - 3. The ideal solution is to just do load balancing through DNS
requests and have 2 servers in a multi master configuration. So far we have
not had any hardware issues on our current set up ( knock on wood). So in
doing this I am not immediately looking for a hot spare set up. But in the
future am looking at setting up a VPN tunnel to an offsite server and
sending WAL updates to that.

Any and all comments are truly appreciated as well as any nudges in various
directions.

David.
