A protocol bridge includes a cache for caching data from a plurality of data storage devices, and for servicing data requests from a plurality of initiators. Data is cached for every data access operation such that the most frequently accessed data remains replicated in the cache.

Multi-protocol bridge with integrated performance accelerating cache

A boot appliance for writing data to a particular host system's boot image and returning boot image data to a particular host system of a plurality of host systems. The boot appliance includes at least one storage medium, wherein the at least one storage medium is configured to store a base boot image and a plurality of variance boot images. The boot appliance further includes a buffer. The base boot appliance also includes a computer readable medium embodying computer code configured to cause the boot appliance to perform a method for writing data to a particular host system's boot image and for returning boot image data to a particular host system of a plurality of host systems.

Method and apparatus to share a single storage drive across a large number of unique systems when data is highly redundant

A SAS expander or initiator places PHYs in a wide port into a persistent reduced power state by signaling to the connected SAS device that the SAS expander or initiator intends to route data traffic through other PHYs in the wide port. The SAS expander or initiator and connected SAS device agree to disuse certain PHYs so that the PHYs enter a reduced power state according to SAS standards.

Method for optimizing wide port power management in a SAS topology

The methods and structure herein provide for expanding the storage capacity of a RAID storage system while maintaining the same level of RAID storage management. A RAID storage controller may be coupled between a host computer and a RAID storage volume. The RAID storage controller manages the disk drives of the storage volume to present a single logical volume of storage to the host computer. When a storage expansion is desired, the RAID storage controller may communicatively couple to at least one expansion disk drive and begin transfer of data from the original RAID storage volume to the expansion disk drive(s). During this data transfer, read and write operations are continued to the original RAID storage volume. Additionally, the RAID storage controller duplicates write operations to the expansion disk drive(s) such that general storage operations required by the host computer are continued.

A data-processing system and method are disclosed, which generally includes a plurality of components connected to a bus within a data-processing apparatus utilizing one or more input/output interfaces (e.g., IOCTL) in communication with the bus. A dynamic interface is implemented, which includes a plurality of interface modules that permits varying data-processing applications to scan, identify and interface with the plurality of components utilizing the input/output interface, thereby increasing data-processing application development efficiency relative to one or more components within the data-processing system.

Application programming interface for fusion message passing technology

A data-processing apparatus, method and program product generally include identifying one or more SAS expanders and one or more link thereof associated with an SAS domain of a data-processing apparatus. Link and reset data can be automatically injected onto the link(s) and the SAS expander(s) associated with the SAS domain, in response to identifying the SAS expander(s) and one or more links thereof. The presence of the link(s) within the SAS domain can then be verified, in response to automatically injecting the link and reset data onto one or more links and one or more SAS expanders in order to test the links and the SAS expanders associated with the SAS domain.

Method and apparatus for injecting errors into SAS domains through SAS expanders

Disclosed is a SCSI target device simulator consisting of a personal computer, a SCSI host adapter board, and simulator software. The SCSI target device simulator is employed to test SCSI host adapter systems by simulating multiple SCSI target devices for test purposes. The simulated SCSI target devices may be configured to imitate a wide variety of different SCSI target device types, with an equally wide variety of configuration settings within a single SCSI target device type. A user may quickly create and change simulated SCSI target devices for a test system. The SCSI target device simulator may also be configured so that the simulated SCSI target devices respond in a specified manner to SCSI commands and SCSI task management commands. Controlling the simulated SCSI target device responses to SCSI commands and SCSI task management commands allows a user to easily configure and test a SCSI host adapter device for specific operational scenarios.
