Abstract: In accordance with the present disclosure, files may be deduplicated in a distributed storage system having a plurality of storage volumes. A uniqueness metric for each file may indicate a degree of deduplication of the respective data files in the given storage volume. The uniqueness metric may be used to identify files for rebalancing in the distributed storage system. The uniqueness metric may be efficiently calculated with enough accuracy using a sampling methodology.

Abstract: A method is provided for use in a system that includes a host computing machine configured to implement a virtualization intermediary and that includes a physical storage adapter, the configures a virtual machine (VM) and a virtual function (VF) to support IO operations to physical storage through a direct IOV path to the VF of the physical storage adapter, the method comprises: creating by the virtualization intermediary mapping information that includes a first mapping between virtual disks and physical regions of physical storage and that includes a second mapping between virtual disks and virtual disk addresses; transmitting the mapping information from the virtualization intermediary over the physical storage adapter from a physical function (PF) of the physical storage adapter to the VF; associating a virtual port with the mapping information within the virtualization intermediary; binding the virtual port to the VF; communicating virtual disk addresses indicated within the second mapping within the transmitted mapping information for the allocated virtual disks to the VM.

Abstract: Techniques for implementing data deduplication in conjunction with thick and thin provisioning of storage objects are provided. In one embodiment, a system can receive a write request directed to a storage object stored by the system and can determine whether the storage object is a thin or thick object. If the storage object is a thin object, the system can calculate a usage value by adding a total amount of physical storage space used in the system to a total amount of storage space reserved for thick storage objects in the system and further subtracting a total amount of reserved storage space for the thick storage objects that are filled with unique data. The system can then reject the write request if the usage value is not less than the total storage capacity of the system.
