5.1 What is a DNA Unit?
The main purpose of the Sheer DNA Units is to host the Autonomous VNEs.
The Sheer DNA Units are interconnected to form a fabric of VNEs that can
inter-communicate with other VNEs regardless of which unit they are
running on. Each Sheer DNA Unit can host thousands of Autonomous VNE
processes (depending on the server system size).
For more information about adding Sheer DNA Units, refer to the section
Adding New Sheer DNA Units on page 71.
The Sheer DNA Units also allow for optimal VNE distribution, ensuring
geographic proximity between the VNE and its managed NE.
