1. A method for deploying one or more virtual machines on a host computing system, the method comprising: receiving mapping information from a data storage system, wherein the mapping information associates a first data chunk stored in the data storage system with a unique identifier to support deployment of a first virtual machine on a host computing system; utilizing the mapping information to determine whether any copies of the first data chunk have already been loaded into a memory of the host computing system in association with deployment of the first virtual machine or a second virtual machine on the host computing system; and in response to determining that no copies of the first data chunk have already been loaded into the memory: retrieving the first data chunk from the data storage system; loading the first data chunk into the memory; and utilizing the first data chunk to deploy the first virtual machine on the host computing system.
