I am after some advice on how to best setup the following environment that I am setting up internally. We are purchasing a Cisco UCS mini along with some Hitachi Fibre Channel Storage to replace some older HP equipment at our main site. We currently use DPM for backing up our Hyper-V VM's, but as you can tell I am wanting to move to Veeam

What I would like to know what is the best method or best practice for this scenario? Should I purchase an external Server with some Direct Attached Storage for the Veeam Server and then purchase another Blade for the Veeam Proxy Server so that I can speed up the backups? Also I want all backups to be on disk only at the moment, so I was thinking of having some smaller storage at the Head Office for Veeam so that I can keep all the latest backups local on site where I may need to urgently restore an entire VM etc, and then I was thinking of having a large capacity storage device at our second office so that I can replicate some backups offsite for long term retention.
What I want to know is does this sound like a good implementation/configuration or should I be considering anything/something else?
Many thanks in advance for any help that anyone can provide.
