Abstract: A data storage server may store a data packet generated by a client in a first server memory prior to the data packet being migrated to a third server memory of the data storage server by a server controller in response to a server data migration module. The data packet may be moved to satisfy a quality of service agreement between a host and the client. The data packet can be proactively copied to a second server memory by the server controller in response to the migration of the data packet from the first to the third server memories.

Abstract: A data storage system can provide low cost and optimized performance with a cartridge housing multiple separate data storage devices and each of the data storage devices being concurrently engaged by a device player. The device player may have a processor configured to analyze mechanical performance of each data storage device and data performance of data resident in each data storage device.

Abstract: Apparatus and method for managing data in a hybrid data storage device. In some embodiments, the hybrid data storage device has a hard disc drive (HDD) controller circuit coupled to non-volatile rotatable storage media and a solid state drive (SSD) controller circuit coupled to non-volatile solid state memory. A local memory stores a map structure which identifies logical addresses of current version data sets stored in the solid state memory. A top level controller circuit operates responsive to the map structure to direct a selected host data transfer access command to the HDD or SSD controller circuit. The map structure may be arranged as a plurality of discrete logical address sequences, where a gap is provided between each adjacent pair of the discrete logical address sequences in the map structure.
