vCenter 4.1 - Can I create a 64 bit DSN to a 32 bit SQL 2005 server?

We are switching to a 64 bit server for vCenter 4.1 (Windows Server 2008 R2).  The documentation for the vCenter server installation says it requires a 64 bit DSN to the SQL database (which in our case is MS SQL Server 2005 32-bit).  Is this possible?  If so, how can I accomplish this?

If you create it on a 64 bit system with the standard admin tools -> ODBC administrator it is a 64 bit DSN. As you further along it may ask for a 32-bit DSN for VMware Update Manager if you are installing that component. Follow the steps in the article Bestway listed above to access the 32-bit ODBC admin tool

Good Luck

Thank you for the comments, but...

Bestway - I am not trying to make a 32bit DSN on my server.

bgoering - I did as you suggested, but the vCenter install says the following:

"The DSN is pointing to an unsupported ODBC driver.  Please re-configure your DSN to use one of the supported drivers."

So my next question is: where do I get the 64bit ODBC driver?

I solved my issue.  I used the Microsoft SQL Server Native Client X64 Package (sqlncli_x64.msi) - 6486 KB.  Located at: Microsoft SQL Server 2005 Feature Pack

Thank you for your comments & assistance!

Hi

But you said you have a 64-bit server and need to implement the vCenter into a SQL 2005 32-bit right? So you need to create a ODBC 32 bit.

@Bestway - he needs a 64-bit DSN because vCenter Service is 64-bit code - no matter what version of database is being accessed.

VUM on the other hand is still 32-bit code and requires a 32-bit DSN

Hi

Humm thats new for me, I tough that we need to use ODBC 32 bit on SQL 32-bit version.
I never used 64 bit server into a 32 bit SQL for vCenter, but I have used in other tools, and all I need to create a 32-bit ODBC using SysWoW64.

But we are always learning on this EE :)

Yeah - maybe http://robertoschiabel.wordpress.com/2008/02/28/windows-x64-32bit-odbc-vs-64bit-odbc/ explains it a bit better than I did. I guess they didn't want to put resources into VUM to upgrade it to be 64-bit code. I think I saw somewhere that VUM (for virtual machines) is going away, and there will be some new process for patches and upgrades to ESX(i).

The sqlncli_x64.msi worked.
