After DustBunny's (valuable and how true...)comments, my 2 cents:

Having lived with different clusters on different platforms, I believe a good and well built and architectured box is less trouble than a cluster ( a box able to crash and reconfigure itself by removing faulty HW...) and almost as fast if not faster than an average cluster...
A well tuned and efficient cluster is different of course, but as DustBunny will confirm - It takes quite some time and skill, by highly qualified personnel...
You just cant follow a procedure to put up a cluster, theres rarely 2 same clusters doing the same thing...
What can you do?
Urgently follow the "Hand-on MSSG" course so you have a good idea what you are being asked!
By following the course, you will get material knowledge and worksheets for you to start to fill with all the prerequisites you will have for your cluster..
Then start to play with the software to see you understand how it works (what you need to get it running) like make yourself a little apache server with read/write webdav and a few WWW authenticated users, and TEST throughly before trying less obvious (oracle DB...) once you are confident with the commands and updates procedure of your simple cluster, go for the big challenge!
It takes, to understand a cluster, the same time to learn UNIX administration (not administering it just understand and not being lost when the gurus come along and modfiy things...) so what do you expect by asking for procedures?
Because of the price of a cluster, you just cant improvise and hope it will work, it is going to ask you quite some investment
The help that can be given to you here is our experience, we can help you putting up your cluster by discussing which architecture is most suitable or by giving you feed back on what we have been through with such configuration, most probably help you sort out with something you are unhappy about with your cluster...

Most valuable advise I can give you:
Remember what UNIX is all about!

So courage my friend and warn your family you will spend less time with them for a couple of weeks for you need to study...

sasl_server_step(3)						  SASL man pages					       sasl_server_step(3)

NAME

       sasl_server_step - Perform a step in the authentication negotiation

SYNOPSIS

       #include <sasl/sasl.h>

       int sasl_server_step(sasl_conn_t *conn,
			   const char *clientin,
			   unsigned clientinlen,
			const char ** serverout,
			   unsigned * serveroutlen);

DESCRIPTION

       sasl_server_step()  performs  a	step  in  the  authentication  negotiation.  It returns SASL_OK if the whole negotiation is successful and
       SASL_CONTINUE if this step is ok but at least one more step is needed.

       conn is the SASL connection context

       clientin is the data given by the client (decoded if the protocol encodes requests sent over the wire) clientinlen is the  length  of  cli-
       entin

       serverout and serveroutlen are set by the library and should be sent to the client.

RETURN VALUE

       sasl_server_step  returns  an  integer which corresponds to one of the SASL error codes. SASL_CONTINUE indicates success and that there are
       more steps needed in the authentication. SASL_OK indicates that the authentication is complete. All other return codes indicate errors  and
       should either be handled or the authentication session should be quit.
