[ha-clusters-discuss] Cluster

[Prasad Dharmavaram]

Atul,

We could add that to the FAQ. I need to check if there is a FAQ
already available somewhere.

But, the following page has some very good information on the
Cluster interconnects hardware requirements:

http://docs.sun.com/app/docs/doc/819-2993/6n58bhek5?a=view

The following document has some information about the cluster
nodes.

http://docs.sun.com/app/docs/doc/819-2993/6n58bhej4?a=view

I agree that the above documents have lot of information targeting
enterprise customers.

we need to get the basic information for developers to get started 
somewhere in a FAQ. If it is already there somewhere others can
chime in.

BTW, in my earlier reply I forgot to give the link to the blog
about Single node Sun Cluster:

http://blogs.sun.com/SC/entry/new_solaris_10_experience

Hope the above links help while we get this info in a FAQ.

Thanks,
--prasad
