摘要:
A system, method and computer program product for managing command ordering for a host-Disk-to-intermediate-Disk-to-Holographic (D2D2H) data storage system. Specifically, a command ordering detects a command from a host system. A hologram segment associated with the detected command is identified and a determination is made whether the hologram segment is an open hologram segment or a closed hologram segment. A determination is made whether the detected command is to be prioritized. If the detected command is prioritized, the detected command is added to a prioritized command queue. Moreover, if the detected command is not prioritized, the detected command is added to a normal command queue. The detected commands addressing the same hologram segment are then grouped. The execution of one or more grouped commands (prioritized or normal) is deferred for a predetermined period to allow for additional commands to be received for a same command group.
