Hello,

You should not have a problem. The only item to look out for is this area "endian-issue", which should not effect you:

http://mysql.com/doc/refman/5.0/en/mysql-cluster-limitations.html

"All machines used in the cluster must have the same architecture. That is, all machines hosting nodes must be either big-endian or little-endian, and you cannot use a mixture of both. For example, you cannot have a management node running on a PowerPC which directs a data node that is running on an x86 machine. This restriction does not apply to machines simply running mysql or other clients that may be accessing the cluster's SQL nodes."

List of supported platforms at: http://www.mysql.com/support/supportedplatforms.html

I assume you have made sure that any table type specific features like full-text in MyISAM or transaction-levels other then READ COMMITTED won't be needed when you transition over to NDB.

Thanks,

Hi there,

We are making the following cluster setup for use in a production environment: Machine 1 - MGM Machine 2 - SQLD1 Machine 3 - SQLD2 Machine 4 - NDB1 Machine 5 - NDB2

Is it possible to run the 64bit release of cluster on the NDB machines and a 32bit release on the other machines?

We are first setting up replication on Machines 2 & 3, then transitioning to cluster after it has been thoroughly tested in-house. The problem is we are having some issues with running our 64bit OS of choice (Debian "etch" amd64) and would prefer to install an older release (Debian "sarge" i386) on the replication machines until we have a chance to iron out the 64bit issues. The problem is that machines 2 & 3 will be in use at that stage and re-installing the OS would be a real hassle - especially as the machines will be co-located.

Thanks in advance, Nathan.
