How do I Backup a DELL Equallogic SAN using EVAULT

We currently have 22 Microsoft Server 2003 Servers. 8 Servers are virtual servers all running on a free version of VMWare.

We are currently looking into purchasing four HP DL380 servers and using the VMware Starter pack to get those servers up and running and we are going to put the virtual machines on aDELL Equallogic SAN. So all 22 servers will run on these Four HP servers.

We currently use EVAULT for backups. We have our Evault Vault on site and replicate the Data to one of our remote offices to another Vault and we periodically backup the remote vault to tape. So this is our environment .

How do people normally backup this type of environment ?
The data will all be on the SAN, the Virtual machines will all be on the SAN
Will Evault be able to backup the data directly off of the SAN ?

I'm looking for a little insight on how people backup these types of setups. I understand every environment is unique, but that is why I'm trying to give as much information as possible.

Thank you for any information

To backup the new environment, there are 2 main options:
1.backup the VM just like physical servers: install backup agents, and create jobs to backup the contents of the virtual server.
2. because the VM's are just a collection of some (large) files on the ESX hosts, you can make a backup of those complete VM (configuration, virtual harddisks, ...). Esxpress or vRangerPro are examples. You can also use VCB for this with a couple of pre-exec and post-exec scripts for your backup software. Keep in mind that the restore is not as simple as with Esxpress or vRangerPro.
Option 1 is usefull for eg fileservers, database servers: if you need to restore 1 file or 1 database, you don't need a complete virtual machine to restore.
Option 2 is usefull if there is corruption in windows, the vm doesn't boot anymore. You restore the complete VM with all the settingsand config
