    Description

      The block manager needs to evolve towards having the ability to run as a standalone service to improve NN vertical and horizontal scalability. The goal is reducing the memory footprint of the NN proper to support larger namespaces, and improve overall performance by decoupling the block manager from the namespace and its lock. Ideally, a distinct BM will be transparent to clients and DNs.
