NEAR MEMORY PROCESSING MODULE FOR DISTRIBUTION OF ALLOCATION UNITS

Provided is a near memory processing, NMP, module (202A-N, 302A-N, 406A-N) for a centralized logging storage array (204, 304) which includes one or more servers (206A-N, 306A-N) configured to host one or more allocation units (208A-N, 308A-N, 404A-N, 502A-N, 604A-N) assigned to a logical volume, where the NMP module is associated with the one or more allocation units. The NMP module is configured to return a current state of the associated allocation unit in response to one or more commands received from one or more client devices (402A-N, 602A-N). The state of the allocation unit includes a mode of the allocation unit which is one of modes including: ACTIVE, UNINITIALISED and SEALED. When the current mode of the allocation unit is UNINITIALISED, the NMP module is configured to change the mode of the associated allocation unit to ACTIVE in response to receiving an append command from a client device (310).
