Abstract
Systems and methods for write-behind caching in distributed file systems. An example method may comprise: receiving, over a network, a direct write request referencing data to be written to a file residing on a persistent data storage device, the file containing at least part of an image of a virtual machine disk; writing, by a processing device, the data to a cache entry of a memory-resident cache, the cache entry corresponding to at least a part of the file; acknowledging the write request as completed; and committing, asynchronously with respect to the acknowledging, the cache entry to the persistent data storage device.
