I'm installing a 2-node Windows 2012 cluster that will be a multi-instance SQL cluster with two SQL instances. I completed the Windows cluster install; now installing first SQL instance. I have a little confusion about SQL network name vs SQL instance name.
Here are the cluster names I have so far...
Windows cluster virtual network name: SQLCLUST01
Node #1 name; SQLCLUST01A
Node#2 name: SQLCLUST01B
Here's what i want to name the two SQL instances...
SQLCLUST01XXX (this SQL instance dedicated to application named "XXX")
SQLCLUST01YYY (this SQL instance dedicated to application named "YYY")
During the install wizard for the first SQL instance, I gave both the SQL network name and the instance name as "SQLCLUST01XXX", and the wizard allowed me to do that. Can you let me know if this correct from an operational point of view? I mean, will anything break or will there be confusion if network name is same as instance name?
