Abstract
The technology disclosed relates to a STRADL file system that transparently deploys file blocks across multiple tiers of storage. In a cloud-based storage platform, multiple storage tiers host data via file system APIs. This includes a volatile storage (VS) tier with a VS API, a reliable non-volatile storage (RNVS) tier with a RNVS API, and a highly reliable non-volatile storage (HRNVS) tier with a HRNVS API. The STRADL file system provides an intermediary file system API that presents to a host system a single interface and translates get, put, and other file system requests into commands compatible with the VS API, the RNVS API, and the HRNVS API, without host system awareness of which of the multiple tiers holds requested data and metadata.
