Re: High Availability Solution question

I'm assuming this is dealing with regular Notes mail . How about iNotes
failover?

Re: High Availability Solution question






Using Domino clusters we clustered three small System i machines for our
company. They are front ended by an F5 networks load balancing box which
directs requests to the least busy server. The three servers are all
remote from each other but clearly they don't need to be. If any of the
servers are unavailable they are simply ignored by the F5 used until
they return. Simple to set up and reliable too.

We'll likely reduce to just two systems now that we're up to Domino 7.

Domino clustering works almost flawlessly for us and has so for many

We have 32 servers in our cluster (mixed windows, Solaris and i5/OS,

with

over 5TB of Domino data clustered.

It is easy to create multiple replicas available on multiple servers

via

ADMINP.

The key to failover for client applications is the catalog.nsf and the
cldbir.nsf. Access to database and servers in the cluster
can be controlled. For very busy apps or servers you can also add

multiple

cluster replicator jobs.

For HTTP we use a cisco load balancer CSM which also makes High
Availability a cinch.
