A first data storage device may be connected to first and second entities as part of a distributed network with each entity having direct block level access to logical block addresses of the first data storage device. The first data storage device can consist of a provisioning module and a staging buffer with the provisioning module configured to store and acknowledge non-volatile write data in the staging buffer in response to a write request to any logical block address of a range of logical block addresses in the first data storage device. The provisioning module may return previously committed data resident in the range of logical block addresses instead of the write data resident in the staging buffer until a commit signal is received from at least one entity for the write data.
