In this week’s episode, Martin and Chris discuss Computational Storage with Tong Zhang, Chief Scientist and co-founder at ScaleFlux. Computational Storage devices add value to traditional NAND by offloading data processes directly onto the storage media. ScaleFlux offers two families of CSDs, including the CSD 2000 series, which implements inline data compression to improve endurance and logical device capacity.
In this conversation, Tong covers the benefits of using CSDs as well as some of the challenges of implementation. It’s likely we will se CSDs being used for AI/Analytics pre-processing, especially in the public cloud.
