Abstract: An illustrative embodiment disclosed herein is an apparatus including a processor having programmed instructions to send an application programming interface (API) write request to a first virtual machine (VM) on a first node to write an object, receive a response to the API write request including a physical disk location of a physical disk to which the object is written, wherein the physical disk is located on a second node, and using the physical disk location, send an API read request to a second VM on the second node to read the object.

Abstract: A virtual computing system deduplicates data. The system includes one or more processors, and one or more computer-readable storage media communicably coupled to the one or more processors. The one or more computer-readable storage media has instructions stored thereon that, when executed by the one or more processors, cause the one or more processors to: scan extents for duplicate data chunks; calculate hash values for the extents at different chunk lengths; emit the hash values at the different chunk lengths; identify matching ones of the hash values; and select one or more candidates from among the matching ones of the hash values for dedup.
