In this podcast, recorded on 6th September 2017, Chris, Martin and Gavin discuss the subject of disaggregated storage. With the move to NVMe, traditional dual controller architectures are hamstrung by the need for all data to go via the processor(s). Disaggregation takes the component parts and makes them scalable, while removing the controller bottleneck. The guys discuss why these solutions are needed, who the players are in the market and what we can expect to see as this section of the storage industry develops.
