Disaggregated Container Attached Storage - Yet Another Topology with What Purpose (DoK Day EU 2022) // Nick Connolly

https://go.dok.community/slack https://dok.community/  From the DoK Day EU 2022 (https://youtu.be/Xi-h4XNd5tE) The storage topology in vogue seems to cycle every few years. Internal storage is followed by centralized Storage Area Networks only to be superseded by one-size-fits-all Hyperconverged models - until scalability constraints led to distributed storage. Then comes NVMe, offering blistering speeds that all of these storage stacks struggle with. Kubernetes inspires Container Attached Storage aspiring to be the perfect model, so why is disaggregated storage now making an appearance?   This talk considers the motivations behind yet another storage topology and examines a modern, flexible architecture for delivering high-performance storage under Kubernetes. Nick Connolly is a pioneer of storage virtualisation and the Chief Scientist at DataCore, where his background in real-time computing and multiprocessing led to the creation of a world-class high-performance storage stack on Windows. He holds patents ranging from highly scalable algorithms through to data protection techniques. Recently he has been working with OpenEBS to bring the power and performance of NVMe to Kubernetes.
