摘要： A service clock regenerator regenerates a local clock from time stamps of a remote clock transmitted over a network by determining the slope of (or difference between current and previous) time stamps of the remote clock and the slope of time stamps of the local clock. A phase difference is formed as the difference between the slope of the time stamps of the remote clock and the slope of the time stamps of the local clock and this phase difference is accumulated to generate a phase error signal. The phase error signal is filtered to generate a frequency adjustment signal having a magnitude that depends on the phase error signal. The frequency of the local clock is adjusted according to the magnitude of the frequency adjustment signal thereby reducing a phase difference between the remote time stamps and the local time stamps. The (local service) clock signal has a nominal frequency of Fc/(N+K/L) Hz over each successive interval of L periods, where N, K and L are integers, and L>K (where K can be the above noted frequency adjustment signal). Each set of L periods includes a first set of K periods and a second set of L-K periods. These two sets of periods are organized by interleaving two or more non-null subsequences of periods of the first set with two or more non-null subsequences of periods of the second set. During each period of one of the subsequences of the first set, the clock is outputted with a frequency of Fc/N Hz. Likewise, during each period of one of the subsequences of the second set, the clock is outputted with a frequency of Fc/(N+1) Hz. A service clock regeneration system with multiple service clock regenerator modules is also provided. A combined service clock regenerator/synchronous residual time stamp generator is furthermore provided.

摘要： A fibre channel disk drive operating system configures a plurality of disk drives into a fibre channel drive loop. The system also provides plurality of disk drive controllers, and a software controlled switching circuit electrically connecting the disk drive controllers to the disk drives which are arranged in the fibre channel drive loop in varying selected configurations. The switching circuit has a plurality of switch elements arranged for selectively electrically connecting each fibre channel drive loop to a selected controller. Each switch element in a first mode of operation passes electrical signals in a through direction and in a second mode of operation passes electrical signals in a second bypass direction. Thereby each fibre channel drive loop is electrically connected to a selected one of disk drive controllers prior to operation of the system.

摘要： A recovery method for use in a data storage system in which a plurality of data storage devices are connected to each of two communication paths. A switch may route requests to either of the two communication paths. With one data storage controller in communication with the data storage devices over a first path and a second data storage controller in communication with the data storage devices over a second path, upon detection of a malfunction on the first path, a data storage controller may request access to the other path. Thereafter, the controller may be switched into connection with the remaining operable path so as to share that path with the other controller.

摘要： A fiber channel, interconnecting a plurality of disk drive loops and associated high speed bypass switches, has a selected group of high speed bypass switches to modularize the fiber channel and to reduce electrical signal jitter on the channel. More particularly, the fiber channel loop has a first group of bypass switches being connected to either connect an associated disk drive to the loop or to electrically isolate the loop from the associated disk drive, and a second group of the bypass switches is then connected, in a first operating state, to connect a group of disk drives and their respective associated bypass switches for electrical signal communications with disk drive controller, and in a second operating state, for electrically isolating the group of disk drives and their respective associated bypass switches from communications with the controller. The disk drives and their associated bypass switches can be modularly added to the fiber channel configuration by employing the second group of bypass switches as high speed controllable gateways.
