VAST Data Architecture

The podcast explores VAST Data's architecture, which aims to deliver all-flash performance at a price comparable to hard drives. It leverages technologies like QLC flash, 3DXpoint storage class memory, and NVMe over Fabrics to overcome the limitations of traditional tiered storage. A key innovation is a disaggregated, shared-everything architecture where stateless containers access a common namespace, enabling independent scaling of performance and capacity. VAST Data employs wide stripes and a new erasure code to optimize data protection and reduce overhead. Data reduction is achieved through similarity detection and delta encoding, catering to unstructured data's unique characteristics. The system is designed for scalability, resilience, and cost-effectiveness, challenging conventional storage paradigms.
