Abstract: A mechanism is provided in a data processing system for data replication. The mechanism divides a set of data to be replicated into a plurality of slices. Each slice of the plurality of slices is to be copied from a primary site to a master secondary site within a plurality of secondary sites. The plurality of secondary sites comprises the master secondary site and at least one subsidiary peer site. The mechanism copies the plurality of slices from the primary site to the plurality of secondary sites such that the master secondary site stores a first slice of the set of data and each of the at least one subsidiary peer site stores a corresponding slice of the set of data. Responsive to completion of copying the plurality of slices to the plurality of secondary sites, for each of the at least one subsidiary peer site, the mechanism initiates copying of the corresponding slice of the set of data to the master secondary site.

Abstract: In a method for determining if a file should be scanned for malware before a deduplication process, receiving an indication that a first file is stored or modified to a computing system. The one or more processors create a fingerprint for the first file. The one or more processors determine that the fingerprint for the first file is not already stored in a repository of one or more stored fingerprints, and in response, scan the first file to determine whether the first file is infected with malware. The one or more processors, in response to determining that the first file is not infected with malware, initiate a deduplication process for the first file. The one or more processors store the fingerprint of the first file to the repository of one or more stored fingerprints.

Abstract: In a method for replicating data, a first controller receives a request to write data from a device. The first controller communicates with a second controller to obtain information necessary for the second controller to receive the data. The first controller determines settings that allow for the first controller and the second controller to each receive the data using the information necessary for the second controller to receive the data. The first controller sends the settings that allow for the first controller and the second controller to each receive the data to the device. The first controller receives the data sent from the device to the first controller and the second controller based on the settings that allow for the first controller and the second to each receive the data.

Abstract: A method for replicating data from a first volume to a second volume includes receiving a first data request comprising a request for a first portion of data, wherein the first portion is part of a first volume. The first portion of data is read, and so is at least a second portion of data in addition to the first portion of data requested in the first data request. In response to determining that the second portion of data should be replicated to the second volume, the second portion of data is written to the second volume.

Abstract: Customizing a target system. The target system may include a first device with a first programmable hardware element (PHE) and a second device with a second PHE. Synchronization modules may be provided for implementation on the first and second PHEs. The synchronization modules may provide a standard interface for interacting with other code. A user may specify user-created code for the first and second PHEs which utilizes the synchronization modules. The user-created code may interact with the synchronization modules using the standard interface. Accordingly, hardware descriptions may be generated for the first and second PHEs of the target system. Different modules may be used for different interconnects. Additionally, multiple synchronization modules may be used, e.g., dynamically, during operation of the target system.

Abstract: Embodiments of the present invention utilize a hard disk drive buffer to minimize seek delays during background replication of a first volume and fulfillment of application input/output requests. According to one aspect of the present invention, a requested first sector of data is read along with one or more additional sectors of data. Upon determining that one or more of the read sectors of data should be replicated, the sectors are read from the disk buffer and written to a second volume.

Abstract: A computer-implemented method for establishing a communications link between a source and a target comprises: a) receiving, at a server, data identifying the source and the target; b) for each of the source and the target, retrieving a respective communication profile identifying one or more communications systems by which the respective one of the source or target may be communicated with; c) comparing the profiles to identify one or more common communications systems; and d) opening a communications link between the source and the target using one or more of the common communication systems.

Abstract: A system and a method are disclosed for performing clock re-convergence pessimism removal (CRPR) during hierarchical static timing analysis (HSTA). A clock network is divided into a plurality of blocks. A top level includes clock components not included in the plurality of blocks. Block level analysis is performed to determine timing information for each of the plurality of blocks. If available, CRPR data from top level analysis is accounted for in block level analysis. Subsequently, similar analysis is performed on components that are included in top level analysis. If available, CRPR data from bottom level analysis is accounted for in top level analysis. CRPR data can be requested during levels of analysis from the other level. These steps are repeated until analysis is complete.

Abstract: Systems and methods are disclosed for operating an interface of an electronic device in an active mode or a power save mode based, at least in part, on a condition of a data exchange module buffer. When buffer space is available, incoming data may be stored locally and the interface used to access remote memory storage may be in a power save mode. The interface may revert to active mode to transfer data to the remote memory, such as after a configurable reception interval. Outgoing data may also be stored in a buffer, allowing the interface to be in a power save mode with information transmitted from the buffer.

Abstract: A system and a method are disclosed for reducing memory used in storing totals during static timing analysis. Totals are stored at various points along paths analyzed in static timing analysis. Some totals may not be merged for reasons including differing clock re-convergence pessimism removal (CRPR) dominators, exceptions, or clocks. Totals at a point may be stored in a super-tag mapping table and replaced at the point with a super-tag. The super-tag includes a super-tag ID referencing the totals stored in the super-tag mapping table. The super-tag also includes a time delay value. The time delay value allows the super-tag ID to be reused in other super-tags at other points while still storing total time delays at the other points. Therefore, the memory used to store totals is reduced in many situations.
