Need suggestions for alternative replication software

Hello - I'm trying to find an alternative to Replisor/Mirrorview to do SAN to SAN and host to host replication. We are currently using those 2 products to replicate from our main datacenter to our backup datacenter, but we understand that we cannot use those same products to replicate from the backup center to our DR (third site) center. Here is our current scenario:

We have 3 different data centers: The first one is our main datacenter. We have 2 ESX servers that host almost 50 VMs with an EMC Clariion SAN, plus some other physical servers that can¿t be virtualized and Cisco Call Management systems. The data from this SAN is replicated to our backup datacenter which is located in another building on this campus. It also contains 2 ESX Servers. We are using Mirror view to do this, and EMC Replistor to replicate the individual physical servers . We have a third datacenter that is our DR center. It is located about 150 miles east on another college campus. It contains a SAN and another ESX server and will have some duplicate physical servers as well.

We cannot use Mirrorview and Replistor to replicate data and servers to the DR site since we are already using it to replicate from the main site to the backup site. Apparently, the software cannot be used to replicate the same data to more than one location.

We need a product or combination of products to replicate SAN data from the backup datacenter to the DR center, and we need some way to also replicate some physical servers to duplicate physical hardware.

Does anyone have any experience with this or suggestions they'd like to share? I appreciate any insight you can provide. Thanks! Jan Dye
