7. Authentication Mode. Although you can use either mode, Mixed
Mode allows you to assign a password to the sa login. (The Service
Pack installation requires that a password be assigned to the sa
account.)
8. Collation Setting. Choose the collation settings appropriate for your
site.
9. Network Libraries. Type a port number for TCP/IP Sockets. You can
enter any unused port number; however, the same port number must
be used on the backup nodes for the associated Virtual SQL Server.
Do not use port number 0, which configures dynamic port
assignment. MxDB for SQL Server needs to know which port the SQL
clients will use to access the SQL database. This means that SQL
Server cannot use dynamic port assignment.
