Celerra and Replication Manager

hello,

i'm supposed to install a disaster recovery solution with the following elements:

-two celerra nx4 , dart 5.6.47.11, located in two sites connected by a dedicated 1 Gb network

- iscsi LUNs, and Cifs shares on celerra.

- two vsphere 4 farm , one in each site.

- Celerra replicator

- EMC Replication Manager with 1 server and 4 agent licenses

- Vmware Site Recovery Manager version 4.01

a bunch of VM's in the production site that makes use of iscsi LUNS on celerra to build VMFS datastores, a few iscsi LUNs

used for store MS-SQL DB accessed with RDM physical mode.

Do all these elements fits and works together ? (Celerra Replicator, Replication Manager, and VMware SRM ??)

How can I account for consistency issues ?

Do I need Replication Manager proxy agent to replicate vmware VMs?

Do I have to put each virtual disk in its own datastore, a datastore for each single vmdk virtual disk?

can I replicate consistently SQL located in RDM disks and use it in case of disaster ?

thanks in advance, Gianluigi
