Abstract: Described is a method of managing adverse reactions that may occur during a medical procedure that involves the administration of contrast media. The method includes acquiring, by a data acquisition unit, information about a patient and an upcoming medical procedure that involves the administration of contrast media, computing in advance of the medical procedure, by a risk assessment unit, a prediction of a risk that the patient will experience an adverse reaction to the contrast media based on the information about the patient and the upcoming medical procedure, and presenting to one or more medical personnel in advance of the medical procedure, by a risk alert unit, an indication of the risk in a visually perceptible form. Also described are systems and software that implement methods of managing adverse reactions.

Abstract: A method and system for manipulating a spin state of each disk in a drive array is disclosed. In one embodiment, a method includes monitoring input/output (I/O) requests to each disk drive in a disk array and identifying any disk drive as an inactive disk drive based on a number of I/O requests directed to said any disk drive for a given time interval. The method further includes moving data from the inactive disk drive to an active disk drive having a free disk space to store the data and updating metadata associated with the data using a log-structured file system for the disk array. Further, the method includes manipulating a spin state of the inactive disk drive by spinning down the inactive disk drive to conserve power. Furthermore, the method includes redirecting subsequent I/O requests for the inactive disk drive to the active disk drive by accessing the metadata of the log-structured file system.

Abstract: The present invention is a system for implementing a meta-disk aggregation model for storage controllers. The system includes a storage controller configured for communicatively coupling with a server. The system further includes a meta-disk drive group having a plurality of disk drives, the meta-disk drive group configured for being communicatively coupled with the storage controller, each of the plurality of disk drives including a drive interface connector. Additionally, each drive interface connector of the plurality of disk drives of the meta-disk drive group is configured for being communicatively coupled to each of the remaining drive interface connectors of the plurality of disk drives, thereby allowing the plurality of disk drives to communicate as a single device with the storage controller.

Abstract: A unified enterprise level method and system for enhancing a performance of applications and storage subsystems in a storage network are disclosed. In one embodiment, a method for enhancing the performance of the storage network having applications and storage subsystems includes collecting performance data associated with the applications and the storage subsystems, and generating performance profiles for a set of combinations of the applications and the storage subsystems implemented in the storage network based on the performance data. The method also includes receiving desired performance criteria for an application of the storage network, and applying a performance profile to configure the application and a storage subsystem assigned to the application substantially similar to the desired performance criteria.

Abstract: The present invention is directed to a method for providing Quality Of Service (QoS)-based storage tiering and migration in a storage system. The method allows for configurable application data latency thresholds to be set on a per user basis and/or a per application basis so that a storage tiering mechanism and/or a storage migrating mechanism may be triggered for moving application data to a different class of storage.

Abstract: Methods and systems for dynamic storage tiering may comprise: discovering one or more remote virtual drives associated with one or more remote storage arrays; advertising one or more local virtual drives associated with a local storage array; receiving one or more IO requests from a client addressed to one or more remote virtual drives associated with one or more remote storage arrays; transmitting one or more command descriptor block (CDB) requests to one or more remote storage arrays associated with the one or more virtual drives to allocate local cache space and transmitting the one or more IO requests to the one or more remote storage arrays via Remote Direct Memory Access (RDMA).

Abstract: A storage area network system having a data storage means for storing computer data, a storage manager routine running on a client, the storage manager routine having functional elements for directing snapshots to be taken of the computer data on the data storage means, and a snapshot ranking manager for determining characteristics of the snapshots, and for selectively deleting given ones of the snapshots based at least in part on the characteristics of the snapshots. The characteristics of the snapshots might include the type of application that uses the data in the logical volume from which the snapshots were taken, or mission critical aspects of the data.

Abstract: The present disclosure provides a methodology by which disk level access for storage drives of a storage array may be highly secured based on permission settings applied to the driver interface of the storage drives. Based on specific set of access rules, a security component applies security profiles to permit/deny access to an individual storage drive, sets the storage drive with a first security level, monitors for a triggering event, and sets the storage drive to a second (more restrictive) security access level in response to the triggering event. In addition, the security component generates an alert in response to the triggering event. Thus, disk level access permissions are applied at a driver interface layer and permissions are applied based on administrator-defined policies. The present disclosure provides for complete lock-down of data permissions, management and/or restriction of IO loads, and protection of “read-only” data integrity from overwrites.

Abstract: A boot menu is provided for manual setting of serial port parameters. A serial console mode menu allows an operator to set serial port parameter values. After the user selects the serial port parameters, when the controller continues with the boot process, the serial port is initialized with the newly selected parameters. A mechanism is also provided for manual setting of serial port parameters through an administrative management window at the host. In addition, an adaptive baud rate negotiation mechanism using the Universal Asynchronous Receiver Transmitter (UART) registers in the serial port is provided. The adaptive baud rate negotiation is based on the return characters received from a break character from the serial console. The mechanism uses a look-up table for the baud rate versus the bit pattern that is received. The mechanism then sets the baud rate based on the look-up table values.
