How to prepare a low cost Cluster DR site???

Hello Friends,

I have a 2 node Active-Active Ex2K3 cluster with EMC200 DAS.

I like to prepare a DR Site for this setup.

You may say a real time DR failover for the whole site.

Anybody has any idea how I can acieve this.

I may opt for a low cost solution, but 1st of all i like to know how can I do this.

Thanks,
Brajesh
