1. A computer-implemented method for reducing client timeouts for a distributed filesystem, the method comprising:

  • collectively managing the data of the distributed filesystem using two or more cloud controllers, wherein collectively managing the data comprises;

    storing the data for the distributed filesystem in one or more cloud storage systems, wherein the cloud controllers cache and ensure data consistency for data stored in the cloud storage systems, wherein each cloud controller is associated with a local storage pool; and

    caching data for the distributed filesystem in the local storage pool of each cloud controller;

    receiving at a cloud controller a request from a client system for a data block from a target file that is stored in the distributed filesystem; and

    delaying the transmission of one or more cached data blocks for the target file from the cloud controller to the client system.
