Improving storage device performance including initiating, on a storage device, execution of a rehabilitative action from a set of rehabilitative actions that can be performed on the storage device; determining that the storage device is operating outside of a defined range of expected operating parameters after the rehabilitative action has been executed; and initiating execution of a higher level rehabilitative action responsive to determining that the higher level rehabilitative action exists.

Addressing storage device performance

Rehabilitating storage devices in a storage array that includes a plurality of storage devices, including: receiving a request to rehabilitate a storage device that is operating outside of a defined range of expected operating parameters; selecting, from a hierarchy of rehabilitative actions that can be performed on the storage device, a rehabilitative action to perform on a storage device in dependence upon information describing a number of times that one or more of the rehabilitative actions have been performed on the storage device; and initiating execution of the selected rehabilitative action.

The present invention provides a mechanism for fast routing of data in a Storage Area Network. A protocol interface module (PIM) interfaces with outside networks and the storage devices, such as over fiber channel (FC). The PIM encapsulates received data into a streaming protocol, enabling storage processors to direct data to/from the appropriate physical disk in a similar manner to the directing of network messages over the Internet or other network.

Method and apparatus for transferring information between different streaming protocols at wire speed

A storage server includes various components that monitor and control the data flow therebetween. If an egress (downstream) port becomes congested, that information is propagated upstream to the egress components such as the port manager, the traffic manager processor, and the egress storage processor, which are each configured to control their data flow to prevent dropped data frames. In addition, the egress storage processor can communicate the congestion information to the ingress storage processor, which further propagates the congestion information to the ingress components such as the traffic manager processor and the port manager processor. The ingress port manager processor can then direct the ingress port to stop accepting ingress data for the storage server to process until the congestion has been addressed.

Apparatus to flow control frames in a networked storage virtualization using multiple streaming protocols

Apparatus and method offloads processing from a networking processor operating in a storage environment. Three main functions are offloaded: semaphore processing, frame order processing, and timer processing. Offloading of semaphore processing enables ordered access to semaphores. Offloading of frame order processing enables the network processor to quickly transmit an incoming frame if the incoming frame is the next one in the frame order. Offloading of timer processing enables background checking of the timer list.

A cache connected to the virtualization engine in the center of a storage area network. The invention caches data in a virtual cache, without requiring translation to the physical location. The cache is done as the data crosses the network through the virtualization engine, eliminating the need to do the further translation and forwarding over the network to the actual storage controller in the event the data is in the cache. In addition, the invention eliminates the need for multiple caches at each physical storage controller.
