摘要:
A redundant data storage system is provided comprising a first controller with top-level control of a first memory space and a second controller with top-level control of a second memory space different than the first memory space. The system is adapted for asynchronously reflectively writing state information by the first controller to the second memory space; alternatively the system is adapted for asynchronously reflectively writing state information by the second controller to the first memory space. A method is provided for operating the redundant data storage system by resolving any inconsistency between the existing state information and a modified state information associated with a state information change request, and for switching control in the redundant data storage system between the controllers.

An address conversion unit for a multiprocessor system including a common memory, and in which at least one processor includes a private memory, with the private memory and common memory having separate and distinct memory spaces. The conversion unit converts addresses between private addresses that are used within the processor itself and addresses that are used to retrieve contents of locations in common memory.

Method and system for consolidating cash letters. Embodiments of the invention provide methods and systems for consolidating cash letter data from a plurality of capture devices and sources. In example embodiments, data from multiple sites and sources can be assembled into a single, endpoint file for a specific clearing institution. The reformatting and distributing of this data can be accomplished using endpoint specific rules and specifications. In some embodiments, a transaction exchange (TRX) stores cash letter data according to a file key and applies the endpoint specific distribution controls to the data to create the specific endpoint files. The transaction exchange can take the form of a data warehouse with processing and storage capabilities necessary to sweep the appropriate cash letter data into an endpoint file as needed. An image archive can be provided to enable appending images to endpoint files.

A reciprocating pump assembly comprises: a motor with a rotary motor drive shaft; a cam coupled to the motor drive shaft with an axis of rotation and a cam channel cut generally axially into a radial face of the cam; and multiple reciprocating pump units arranged radially about the cam axis of rotation, each with an inlet valve, an outlet valve, a plunger and a plunger sleeve, with a free end of its plunger coupled to the cam by way of a cam follower riding in the cam channel; wherein rotation of the motor output drive shaft causes the plunger in each pump unit to independently reciprocate in its respective sleeve.

摘要:
The present invention provides a method for copying data through a virtualized storage system using distributed table driven (I/O) mapping. In a system having a virtual disk (the “original disk”), a persistent mapping table for this virtual disk exists on a controller, and volatile copies of some or all entries in this mapping table are distributed to one or more more mapping agents. The method of the present invention creates a new virtual disk mapping table that has the exact same entries as the mapping table as the original virtual disk. The new snapshot disk then shares the same storage as the original disk, so it is space efficient. Furthermore, creating new snapshot disk involves only copying the contents of the mapping table, not moving data, so the creation is fast. In order to allow multiple virtual disks to share storage segments, writes to either the original virtual disk or the snapshot copy cannot be seen by the other. Therefore, in addition to simply copying the mapping table, both the original and snapshot disk mapping table must also cause writes to these disks to be handled specially. Finally, any changes to the original disk mapping table stored in the controller must be coordinated with the volatile copies stored in the mapping agent in such a way so that all hosts see a consistent view of that disk.

A data storage subsystem in a distributed storage system having a plurality of predictive failure analyzing data storage devices. The subsystem furthermore has a circuit that is responsive to a predicted failure indication by a data storage device in relation to predetermined rules stored in memory for deterministically initiating a preventive recovery either by a data recovery procedure in the data storage device or by a fault tolerance storage arrangement in the subsystem.
