Abstract: A combination of a host system and a storage system is disclosed that facilitates improved responsiveness of the host system to user requests. In one embodiment, the host system includes a cache management module, a partitioning module, and a driver. The cache management module determines write data to cache to a dedicated zone of a hard disk media of the storage system. The partitioning module partitions the hard disk media into one partition including the dedicated zone and another partition not including the dedicated zone. The driver transmits storage access commands to the storage system to cache data in and retrieve cached data from the one partition. Thereby, the host system can access the write data from the hard disk media more quickly than if the write data were cached in and accessed from another zone of the hard disk media.

Abstract: A disk drive is disclosed comprising a disk comprising a plurality of tracks, and a head actuated over the disk. One of the tracks is read to generate a read signal, and a noise signal is injected into the read signal to generate a noisy read signal. An off-track read capability (OTRC) is measured based on the noisy read signal, and a parameter of the disk drive is adjusted based on the OTRC.

Abstract: A technique includes communicating a message to a dynamic translator in response to a change, which affects the validity of a translation that is performed by the dynamic translator.

Abstract: A communications system (10) is provided which comprises a plurality of network hubs (12), (14), and (16). Network hubs (12), (14), and (16) are interconnected through a communications network (18). The system (10) interconnects messaging systems (24), (26), (28), (30), (32), (34), (36), (40), (42) and (44) having disparate capabilities and using disparate communications protocols. The network hubs use numbers of connection processors (52) and (54) to interact with the messaging systems. A hub database (68) and message store (58) are used to store control information and messaging information within the network hubs. A network processor (60) is used to interact with other hubs within the communications system (10). A message router (72), connection manager (74), data replicator (76), and an administrative event manager (78) are used to control the operations of-the hub in processing a message.

Abstract: In a data processing system comprising a host system and a memory device including a data storage medium of a predetermined size and corresponding capacity, a secure method of managing available capacity of the storage medium by: maintaining an authentication list comprising a plurality of entries including information uniquely identifying a plurality of memory devices; selecting a section of said data storage medium for data storage, said section having a size representing the available capacity of the memory device; and maintaining identification information in the memory device uniquely identifying the memory device.
