Current Problem
Abstract: Many emerging white box storage systems replace
mature, robust drive networks with simple point-to-point drive port
topologies
The presentation provides fault tolerance where each storage
controller has a dedicated port to a drive, but no hardware path to
other port(s) to that drive. The redundant access to media is provided
via Non-Transparent Bridging (NTB), Ethernet, or other networks to
overcome lack of redundancy in the topology.
