64 bit Edition and 32bit Participate in VIRTUALSQL Cluster

Does anybody know if you can mix x64 and Itanium editions?

No, absolutely not.

Itanium and x64 are differenct processor architectures. Software that uses low level services has to be written for one or the other and cannot operate on both.

Granted, there is some software that may easily execute on both -but SQL Server is NOT able to execute on both.

|||Just to be clear I was asking if an x64 and an Itanium could participate in a cluster together.. not if the software would run of the respective machines?|||

There would be no point in clusting an x64 and Itanium machine together as the needed software wouldn't be able to run on both nodes.

Because the installers would be different you woulnd't be able to install SQL on the cluster.

Machines which are in a cluster should be of the same hardware architechurer.

64 bit

Has any mention of the 2008 editions been available? As with 2005 the Enterprise edition of SQL Server 2005 was the only one that supported 64bit OS will this be the same for 2008(Ehendricks880@.discussions.microsoft.com) writes: > Has any mention of the 2008 editions been available?

SQL Express (and I assume Workgroup) runs on x64 as well, but only as 32-bit applications. -- Erland Sommarskog, SQL Server MVP, esquel@.sommarskog.se Books Online for SQL Server 2005 at http://www.microsoft.com/technet/prodtechnol/sql/2005/downloads/books.mspx Books Online for SQL Server 2000 at http://www.microsoft.com/sql/prodinfo/previousversions/books.mspx
