Hi

Can anyone confirm the following:

How many nodes ( active and passive ) can you have with Windows 2008
Enterprise?

Am I correct in saying that it support more flexible quorum models
than Window 2003, and it also supports clusters on different IP
subnets.

Many Thanks

Nick

2008 is going to support 16 node clusters. You are correct in saying that it
will offer more flexible quorum models and will also support nodes on
different subnets.

There are some great webcasts coming up over the next couple of weeks.
Please see the following for more details:

The 32-bit version will support 8 nodes and the 64-bit version will support
up to 16 nodes.

Yes. It supports a few different quorum models. You can read a little bit
more about that here:

That is also correct, but you need a storage environment that will also
support multi-site clusters.

I believe Exchange however still only goes to 8 nodes for SCC even with the
64bit version of Windows 2008.

Further,

Windows 2008 supports cluster nodes in different AD sites, Exchange 2007
does not support this feature. However with Windows 2008 cluster nodes can
be on different subnets - however the same AD site is a must. This is for
both CCR and SCC clustering technologies.
