Abstract
A virtualized computer system employs a virtual disk with a space efficient (SE) format to store data for virtual machines running therein. Data within a virtual disk with a SE format is stored in a grain, where multiple grains are included in a storage block. Writes to a grain within shared storage block in a virtual disk with an SE format are serviced by allocating a new grain and storing the write data to the new grain. Metadata associated with the client that transmitted the write request to the virtual disk is then updated to point to the new grain instead of the grain within the shared storage block.
