Abstract:
A method for allocating storage for a virtual machine includes receiving a request to allocate a block of disk storage on a physical disk to a virtual disk associated with the virtual machine. The method also includes identifying a plurality of available blocks on the physical disk, each of the plurality of available blocks defining a radial distance from a center axis of a platter of the physical disk. The method further includes determining which of the plurality of available blocks has a greatest radial distance from the center axis of the platter and, based on the determining, selecting an allocation block from the plurality of available blocks, the allocation block having the greatest radial distance from the center axis of the platter. The method also includes allocating the allocation block to the virtual machine.
