Vmware Backups w /Networker using DDBoost

Hi,

We have a customer that backups their Vmware environment by TSM but has just been convinced by us to manage the related environment by Networker rather than TSM. Related customer has DD990 as their main target.

As we’ve started the discussions before installation of Networker, network admins has involved into the project.  They are wondering about the impact of our new backup mentality on their network infrastructure. Costumer’s Vmware is totally on 10g network. Networker server will be AiX.

·         Does anyone has example or solid results for Vmware backup performance in case of Networker w DD Boost over 10g to DD990?  Dedup rates are also needed.

·         The most important question is based on the example below :

Example : Customer has 2 ESX hosts.  ESX1 and ESX2. vCenter is on ESX2. There is no Virtual Proxy on ESX1. When I want to backup a VM (on ESX 1) that has 10 GB data on it and daily change rate is %10  :

§  How much data will flow thru the network? Do we send data from proxy to DD? If yes, how much data would It be? As big as the snapshot size?

§  Do we send data directly from Virtual Machine to DD? If yes, how much would It be? As big as the change rate? Any dedup benefit?

Thanks,
