The present invention is directed to a distributed data migration and storage system and method configured for fully parallel writing and retrieval of data objects to (and from) the Web Object Scaler (WOS) object storage system with highly efficient accessibility and using a simplified set of filing commands. The data objects migrate between data generating entities and the WOS object storage through an intermediate Burst Buffer tier (supported by the Infinite Memory Engine) without the utilization of a serial process substantially simultaneously through parallel channels. The metadata for each object is captured with appropriate pointers for efficient finding of the object in the WOS storage system. The WOS nodes return the stored objects' ID (OIDs) corresponding to the objects storage address which are used for the object access.

Method and system for parallel file operation in distributed data storage system with mixed types of storage media

Systems and methods for automated firmware update with rollback are described herein. The systems include a plurality of storage zones, each storage zone including a plurality of storage nodes, each storage node including a plurality of storage media. The method includes monitoring storage system activity and parameters and maintaining a data storage system usage and parameter database containing system activity information. When a firmware update is available, data storage system activity is evaluated. Storage nodes needing the firmware update are identified. The firmware update is run on available storage nodes identified as needing the firmware update. The impact of the firmware update is evaluated and a rollback of the firmware update is initiated on all firmware updated storage nodes when parameter variations are significant and/or result in degraded performance.

Automated firmware update with rollback in a data storage system

Systems and methods for storing data in a data storage system that allows dynamic context-based data protection and distribution are disclosed. The method includes receiving a storage request and evaluating whether a storage policy is specified in the storage request. When the storage request specifies a storage policy, the data is stored according to the specified policy. When the storage request does not specify a storage policy, meta data and/or the data item itself may be evaluated to identify a storage policy. When a storage policy has been identified, store the data is stored according to the identified policy. When a storage policy has not been specified and cannot be identified, an error is returned.

Dynamic context-based data protection and distribution

A failure resilient distributed replicated data storage system is described herein. The storage system includes zones that are independent, and autonomous from each other. The zones include nodes that are independent and autonomous. The nodes include storage devices. When a data item is stored, it is partitioned into a plurality of data objects and a plurality of parity objects calculated. Reassembly instructions are created for the data item. The data objects and parity objects are spread across all nodes and zones in the storage system. Reassembly instructions are also spread across the zones. When a read request is received, the data item is prepared from the lowest latency nodes according to the reassembly instructions. This provides for data resiliency while keeping the amount of storage space required relatively low.

The data objects, parity objects and reassembly instructions are spread across nodes and zones in the storage system according to a policy for the data item. When a zone is inaccessible, a virtual zone is created and used until the intended zone is available. When a read request is received, the data item is prepared from the lowest latency nodes according to the reassembly instructions, and a virtual zone is accessed in place of a real zone when the real zone is inaccessible.

A control processor manages the power budget in a drive enclosure and is within the drive enclosure which monitors in real time a redundantly configured power supply unit, drives, interposers, and temperature sensors, and determines the power settings for each drive to avoid overload and overheating in the system. The control processor dynamically adjusts the mode of operation as needed during operation through the SAS interposer. A localized monitoring and control mechanism eliminates the need for extraneous coordination of information across various entities that access the storage. Data tunneling takes place directly between the compute nodes and target drives through the SAS expander and interposer, and does not need buffering the pending IO requests in the DRAM.

A system for data migration between a compute cluster and disk drives by inclusion of a buffer node coupled to the compute cluster to store data received therefrom in a random fashion. The buffer node signals the computer nodes to promptly return from the I/O cycle to the computing state to improve the duty cycle of the device. The system further includes a storage controller which is coupled between the buffer node and the disk drives to schedule data transfer activity between them. The data transfers are actuated in the sequence determined based on minimization of seeking time and tier usage, and harvest priority, when the buffer node either reaches a predetermined storage space minimal level or a predetermined time has elapsed since the previous I/O cycle. The storage controller deactivates the disk drives which are not needed for the data transfer.

In a data storage system, failed disk drives are switched temporarily off-line to be quickly rebuilt by executing a journaling/rebuild algorithm which tracks the updates to the failed disk drive into a journal structure created in a non-volatile memory. The journal information is used to update those data sections of the disk drive affected by updates after the disk drive is failed. The journal information is stored in bit maps indicating which portions of the disk drive have been updated with new data while the disk was failed. As an option, the system permits verification of data consistency on the data section of the disk drive which have not been affected by the updates. The journaling/rebuild of failed disks is applicable, among others, to RAID data storage systems.

A system for detecting the precise location of a reflective element in a video field wherein the determined location is subsequently utilized to generate a graphic to be added to a foreground video scene utilizing compositing techniques. A signal is generated specifying a precise point in the foreground video scene identifying a position of a reflective element. The signal is derived from a peak detector which generates a pulse whenever the signal input to the pulse detector is at a maximum level for the current video field being scanned so long as the scan is not in the blanking area. The pulse is used by a vertical line counter and a horizontal pixel counter which specify the line and pixel on a horizontal scan line within a video field representing the position of the highest peak generated within that field. Graphics can be repositioned or lines or other graphic elements can be generated which track the movement of the reflective element.

A system which allows the weather television personalities to move and place computer generated symbols onto a weather map background image using only his hand or finger as a pointing device. The weather forecaster is generally in front of a blue screen and must make it appear that he can actually see the weather map behind himself. In the video frame, which is raster scanned, the hand pointing to the object to be moved or placed translates to the first object in the raster (on the left) or the last object in the raster (on the right). The present invention is a method and apparatus which identifies the rightmost or leftmost point in the raster and communicates this information to a graphics computer as x-y coordinate data. The data is utilized by the computer to place a movable graphic symbol at the weather forecaster's fingertip allowing him to move and place the symbol.

An apparatus and method which control the gain of the key signal dynamically and thereby compensate for the effects of an unevenly lit backing or lens vignetting. This dynamic control occurs over a video frame and has the effect of modulating the key signal. In this connection, there are four possible gain controls as follows: a) a horizontal ramp to increase the level of either side (left or right) of the key signal; b) a vertical ramp to increase the level of the top or bottom of the key signal; c) a horizontal parabola to raise or lower the gain of both sides of the key signal simultaneously to nullify lens effects; and d) a vertical parabola to raise or lower the gain of both the top and bottom of the key signal simultaneously to nullify lens effects.

A man to machine interface for the control of video or motion picture camera movement for use with a camera aiming system which can reproduce a specific camera movement any number of times. The interface moves the camera in the pan or tilt axis giving an operator a natural control feel while actually driving the camera movement with a motor drive. A shaft encoder detects the velocity of the motor drive and stores such information over time in a memory. The data stored in the memory may be read out at a later time and used by the motor drive to replicate the movement of the camera.
