Geo-Clustering Server 2008

[Brovane]

At my work we are looking at some DR setups. One item that I was looking at was in Server 2008 is there is much better support for Geographically Dispersed fail over clustering.

One setup we were looking at is having two dispersed SANs, one at our main-site and then another one at another site in another state. These SANs would then user EMC Mirrorview/A to synch data between the two SANs. At the primary site we would have 2-Nodes of the cluster in a active/Passive setup and then the DR site would have one Node. So we would have a A/P/P setup for clustering. If the primary site goes down we could failover to the DR site.

Has anybody ever looked at this, our setup a geo-cluster?

Thanks,

Use VMware with SRM

VMware SRM currently doesn't work with EMC Mirrorview /A you would have to use Mirrorview /S. However due to the fact that the DR site is in another state we cannot use Mirrorview /S effectively. Basically if you are using Mirrorview /S you need dark fiber between the SANs. In the future it looks like VMware SRM will be able to work with Mirrorview /A.

We do have a VMware ESX cluster and we will look at VMware SRM once it can support Mirrorview /A. However even then we are not going to VM our main cluster servers like SQL, Exchange and F&P. These are the servers that we are looking at geo-clustering for DR purposes.
