Systems and methods for implementing volume sets in a storage system. According to a first embodiment, a system may include a volume server, a first and a second client computer system, and a plurality of physical block devices. The volume server may be configured to aggregate storage in the plurality of physical block devices into a plurality of logical volumes, wherein a given logical volume includes storage from at least two physical block devices, to distribute a first subset including at least two of the plurality of logical volumes to the first client computer system for input/output as a first volume set configured to be accessed as a single logical device, and to distribute a second subset including at least two of the plurality of logical volumes to the second client computer system for input/output as a second volume set configured to be accessed as a single logical device.
