Abstract: A first data storage rack has a first computing unit coupled to a first plurality of storage drives via a first storage controller. A second data storage rack has a second computing unit coupled to a second plurality of storage drives via a second storage controller. A first rack-to-rack storage link cable couples the first computing unit to the second storage controller such that the first computing unit can provide access to the second plurality of drives in response to a failure that prevents the second computing unit from providing access to the second plurality of drives via a system network.

Abstract: A composite layout to store one or more extents of a data object in a first storage system and one or more extents of the data object in a second, different storage system. The first storage system may be configured for the efficient storage of small chunks of data such as, e.g., chunks of data small than the addressable block size of the storage devices used by the storage systems.
