Method, system, and program for recovery from a failure in an asynchronous data copying system

InactiveUS20050071708A1Application downtime is minimizedMemory loss protectionUnauthorized memory use protectionRecovery methodDevice form
A method of recovery from a data storage system failure in a data storage system having a host computer writing data updates to a local storage controller at a local site. The local controller is associated with a local storage device. The local storage controller is also configured to asynchronously copy the updates to a remote storage controller associated with a remote storage device at a remote site. In addition, the remote storage controller is configured to store a consistent point in time copy of the updates on a backup storage device. The consistent point in time copy is known as a consistency group. Upon detection of a failure associated with the local site, a determination is made whether a group of updates pending for storage on the backup storage device form an intact consistency group. If an intact consistency group has not formed, corrective action may be taken to create an intact consistency group. The recovery method further consists of synchronizing the remote storage device, initiating recovery operations and, upon recovery of the local site, resynchronization of the local storage device and the backup storage device to recovery consistency group without the need for full volume storage copies and while minimizing application downtime.

Maintaining write order fidelity on a multi-writer system

Write order fidelity (WOF) is maintained for totally-active implementations wherein a plurality of access nodes at geographically separated sites can concurrently read and / or write data in a “totally active” fashion on a distributed data system. From the hosts' perspective at diverse geographic locations, a synchronous, cache-coherent view of data is provided. Data transfer is asynchronous. A time ordered data image is created and maintained so operations can be restarted after a partial system failure that causes loss of data not yet asynchronously transferred across the network, but that has been write-acknowledged to the originating host. Time ordered asynchronous data transfer is implemented as a pipeline of changes that reflect contributions from all nodes. WOF also improves network performance and lowers bandwidth consumption. Extensions can provide, in a totally-active context, features such as point-in-time snapshots, time firewalls, on-demand backend storage allocation, synchronous / asynchronous distribution of data, and continuous data protection.

Local communication system

Examples of local communication systems are disclosed, based on a ring of point-to-point links, providing for transport of fixed rate synchronous, fixed rate asynchronous data and variable rate data in a flexible format. Different segments of the ring network can carry data at different bit rates, while remaining synchronized to a common frame rate and having a common control channel structure, for compatibility with earlier systems. Parallel channels are provided, either permanently or when required, for signalling errors of source data, data validity / padding, flow control. Parallel variable width channels are defined with free content (stream or packet). Null data symbols are defined for padding on a byte-by-byte basis. The allocation of capacity among variable width channels is revised block by block, and a transition period is defined to allow for ring latency. Calculations for allocation of capacity are performed during one block for the next block, locally at each source station, according to predetermined rules. Information as to bandwidth requirements is exchanged prior to the calculation via a special connection signalling channel and message format.

System and method for asynchronous data replication without persistence for distributed computing

A system and method of lightweight asynchronous data replication that avoids the need for any persistent store at the replication source or communication channel, and is independent of the underlying data formats, wherein the method of data replication comprises replicating deltas from a source, embedding replication tracking information in the replicated deltas, wherein the tracking information comprises a timestamp and a sequence number, and applying deltas at a target. The tracking information is used to ensure that each delta is applied exactly once. In the event of a crash in the system, the target analyzes the tracking information to determine which deltas have been applied, and requests retransmission of replicated data from the source starting from the earliest unapplied delta. The source and target are treated as only delta producers and consumers, and as such the invention is applicable to replication between arbitrary data source formats.

Method of synchronizing events with a digital television audio-visual program

A method and apparatus for synchronizing an event produced at a digital television receiver with an instant of a transmitted video, audio, or data element of a digital television program is disclosed. In a digital television system, a system time clock generates a timeline that is used to synchronize the presentation of the video, audio, and data elements of the television program. An application time is used in program production to synchronize instants of the several program elements. To synchronize a receiver generated event with an instant of a transmitted video, audio, or data program element, samples of the application time are transmitted to a receiver in a synchronized data service. A reconstructed application time is generated at the receiver as a function of the current system time, the application time sample, and the presentation time stamp of the data access unit in which the application time sample was transmitted. The presentation time of the program instant is associated with an application time correlating the event and the instant. The correlating application time is transmitted to the receiver as part of a synchronous or asynchronous data service and the event is instigated when the reconstructed application time corresponds to the correlating application time. A clock for generating a reconstructed application time synchronized to the system time is also disclosed.

Multi-channel power line exchange protocol

A scalable networking protocol that allows multiple nodes to communicate via a multi-channel network medium is described. The networking protocol allows any node on the network to assign itself as the active network server. The active network server polls client nodes based on a lineup card. The lineup card includes a high priority queue for low-latency devices, and a low priority queue for devices that can tolerate higher latencies. Network information is sent on the channels as fragments. The protocol provides bad-channel detection and retransmission of fragments in a fragment-by-fragment basis. Support for streaming data or asynchronous data is provided by allocating time slots on the network and allowing two intelligent nodes to talk directly to each other during count-limited token sessions, as arbitrated by the active network server. The network node serving as the active network server can be changed on a dynamic basis, and is typically determined by the first node initiating a transmit request on a sleeping network. Client nodes are addressed by dynamic-polling using an address isolation scheme.
