I've been given the task of transferring the contents of a SQL Server instance from one Windows server to another Windows Server. One of the many things I need to do on the new server is set up the TempDB. I have read in many articles that the rule of thumb for the TempDb is to put it on its own drive and create 8 equal sized files that use up most of the disk. However this applies to where there is only one instance of SQL Server.
The new server has 2 instances of SQL server installed and I've tried to find recommendations for setting up the TempDb files in this situation and I can't find anything.
How should I be setting up the TempDb files in this case? Do I just allocate 1/2 of the disk space to each instance and go from there?
The new instances of SQL server are SQL Server 2016.
