Re: Windows 2008 - Nodes in different subnets

Definitely. I also forgot to mention the tunable heartbeat timeout
parameters...not locked at 500ms any more! :)

Also, I believe it's now being referred to as "multi-site Failover
Clustering" - geo-clustering is someone else's term technically.

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.

Thanks, that is what I was assuming. So basically this just makes
Geographically Dispersed Clustering as it is today a little easier.
