vCenter Server 4.1 & vCenter Update Manager 4.1 DSNs for SQL Server 32-bit

I recently got asked a few times about what DSN to use for 64-bit and 32-bit versions of SQL Server so I thought I’d write a post to get that cleared up.  The answer is regardless of what version of SQL Server, whether it’s 32-bit or 64-bit, you should use a 64-bit DSN for vCenter Server’s database and a 32-bit DSN for vCenter Update Manager’s database.  The DSNs only matter to the application that’s using it and does not care what version the database on the other end is.

Application Application Architecture DSN Required
vCenter Server 4.1 64-bit 64-bit
vCenter Update Manager 4.1 32-bit 32-bit
