Re: Windows 2008 - Nodes in different subnets

Failover Clustering (the new name for MSCS in Windows Server 2008) won't
have any particular built-in technology to address the storage replication
needed to allow all nodes to access the same shared storage.

To be fair, unless your application (Exchange, SQL, etc.) requires shared
"data", Failover Clustering doesn't necessarily require this with some of
the new witness disk (quorum) configuration options. You could configure a
file share witness and build your cluster nodes in separate subnets.

I'd imagine your assumptions about storage based replication as part of the
complete solution are true...

Hope this helps,

I see that one of the new features MSCS in Windows Server 2008 is the
ability to have cluster nodes that are in different subnets. Does
this feature assume that the nodes will have access to the same shared
storage device, or is MSCS going to have built in support for some
type of replication technology?

How do you envision this feature (failing between subnets) being
deployed in the field? Will it strictly be used for disaster
recovery, or do you think it will also be used for HA?

Do you imagine storage based replication or host based replication
being integrated with this solution to offer complete protection from
a loss of the primary data set?

Thanks for your feedback.
