How to: Dell EMC Data Domain Virtual Edition Install on ESXi

It is the market leader in purpose-built backup appliances.  Various workloads can be ingested, including data from Avamar, VEEAM, Networker, etc. Like the Avamar VE, DataDomain VE allows you fully take advantage of virtualization in one easy to manage package.
