Abstract
In one embodiment, a first computing device receives a write request and data from a second computing device; iteratively attempts to write the data until a copy of the data is successfully written to each and every storage node belonging to a storage volume; and transmits a volume identifier of the storage volume and a data identifier assigned to the data to the second computing device. In one embodiment, a first computing device receives a read request and a volume identifier and a data identifier from a second computing device; accesses a cache to select the storage volume identified by the volume identifier; iteratively attempts to read data identified by the data identifier until a copy of the data is successfully read from a storage node belonging to the selected storage volume; and transmits the copy of the data to the second computing device.
