Abstract
A storage system includes storage resources, front-end devices, and back-end devices that are subdivided into allocation units. Each front-end device has a plurality of tracks, which map to entries in the allocation units. Front-end metadata is used to specify, for a respective track, a respective back-end device, an allocation unit within the respective back-end device, and an entry within the respective allocation unit where the data for the respective track is stored. Back-end metadata is used to specify, for a respective back-end entry, a respective location in the storage resources of the storage system where the data for the respective track is stored and a size of the data on the storage resources. The back-end metadata is organized using shared back-end metadata memory pages, in which each page of metadata is equally shared between two or more of the allocation units.
