Hi people,

I have a project for implementing HA solution on 2 Solaris servers. I
have decided to use Sun Cluster. Usually, I work with Red Hat cluster,
but as I see Sun's cluster documentation online, this is pretty much
similar tehnology ... I do not expect problems.

However, I have one dilemma - one unknown bit in my plan: is shared SCSI
or FC storage mandatory for version 3.2 of Sun Cluster?

No, you can live without it. As you mentioned, for a two-node cluster
you will definitely want to use a quorum server.

Note that if you intend to buy support for Sun Cluster, it seems that
Sun will insist on having your cluster installed for you by Sun
Professional Services, which basically priced Sun Cluster out of the
running for us.


Well, that's understandable from Sun's point of view. Either your setup is really important and then cost is no issue, or it is not all that important and then cost is crusial and you are better off without a HA cluster. Todays machines are so reliable that the complexity of cluster causes more downtime if not installed and taken care of correctly than running a single machine with as much redundancy as possible. Believe me, I've done clusters for years...

It's a "Don't try this at work, kids..."
