Abstract
Systems (e.g. data centers) having composable infrastructure, in which computing devices (e.g., servers) access disk drives organized into storage groups over a network or other communications mechanism, devices for implementing such systems, methods for configuring and operating such systems, and a computer readable medium which stores (in non-transitory fashion) code for performing any embodiment of the inventive method or steps thereof. Typically, the storage groups are determined such that the drives in each storage group have at least one coupled failure mechanism, and the drives are allocated to servers (and typically also, data items are placed in the servers) in accordance with storage group membership of the drives. In some embodiments, data from a server is stored in redundant fashion on at least two of the drives, e.g., in accordance a RAID technique.
