Symptoms

This article helps the reader understand the differences between the two methods which Avamar uses to communicate system health and status information to Dell.

Avamar has two distinct and separate features which allow it to communicate information to Dell in order to facilitate effective support for the product.
  • EmailHome
  • DialHome
Dell Technologies recommends that both features are enabled as each offers specific functionality and benefits to the end user.
The features are configured and enabled independently. Either (or neither) may be active on a system.
