High availability is provided in a storage system. The storage system includes a plurality of storage devices having reserved space, for example, for an operating system. Several power branches provide power to the storage devices. At least one of the storage devices is coupled to a first of the power branches, and at least one other storage device is coupled to another of the power branches. Furthermore, each of several devices has a unique address represented by a separate plurality of address bits. Logic produces intermediate bits, the number of intermediate bits being fewer than the number of address bits. The intermediate bits are used to drive the address bits. Some of the intermediate bits drive more than one address bit.
