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.

Abstract: A method enables a central management service to operate on individual files within virtual disks associated with different virtual machines (VMs) running in one or more host computers that are each networked to a remote storage system. An IO request from a VM is received at a virtualization software layer on a host computer, wherein the IO request relates to a file stored in a virtual disk associated with the VM, and the file is individually stored in the remote storage system in accordance with a file system. The central management service is notified of the received IO request and uses the file system to access the file in the remote storage system to perform a management task on the file, and the IO request is then performed on the file by the virtualization software layer upon a notification of a successful completion of the management task.
