Abstract
A method and computing device for write-back caching. A client write request to write new data to a selected file on a volume (for which the client has mounted the corresponding cache) may be received at a network module of a node and processed to generate a write request that can be forwarded to a disk module hosting the cache (at a same or different node than received the client write request). The data is written to the cache and confirmation of the write is sent to the client. Accumulated data in the cache is written back to the volume (hosted by a different node than the cache) when at least one of a cache file threshold or a cache threshold is met. These parameters are set to values that reduce write latency, increase throughput, and help ensure data consistency and resiliency.
