20120158652 | SYSTEM AND METHOD FOR ENSURING CONSISTENCY IN RAID STORAGE ARRAY METADATA - A system and method for ensuring consistency in RAID storage array metadata is disclosed. In one embodiment, the RAID storage array metadata residing in one or more drives is consolidated onto a metadata base volume that is in sync with the current RAID storage array metadata. Further, a point-in-time (PIT) image of the consolidated RAID storage array metadata in the metadata base volume, a system configuration (SC) file, and customer support data (CSD) are obtained. The PIT image, the SC file and CSD can be obtained based on a predetermined time interval and/or upon a change on the RAID storage array metadata. Furthermore, a delta change between two substantially sequentially obtained PIT images, SC files and CSD are determined. In addition, a consistency check (CC) is performed on the RAID storage array metadata based on the determined delta change. | 06-21-2012 |
20120159474 | SYSTEM AND METHOD OF I/O PATH VIRTUALIZATION BETWEEN A RAID CONTROLLER AND AN ENVIRONMENT SERVICE MODULE IN A STORAGE AREA NETWORK - A system and method of I/O path virtualization between a RAID controller and an environment service module (ESM) in a storage area network (SAN) is disclosed. In one embodiment, a type of I/O request is identified by an input/output (I/O) control engine upon receiving an I/O request from a host computer via a RAID controller. Further, a priority is assigned to the received I/O request based on the type of I/O request by the I/O control engine. Furthermore, the processing of the prioritized I/O request is interrupted by the I/O control engine. In addition, the prioritized I/O request is separated into a command I/O request or a status request. Also, the separated command I/O request or the status request is sent to an associated queue in a plurality of solid state drive (SSD) buffer queues (SBQ) in the I/O control engine. | 06-21-2012 |
20120278551 | METHOD AND SYSTEM FOR COUPLING SERIAL ATTACHED SCSI (SAS) DEVICES AND INTERNET SMALL COMPUTER SYSTEM INTERNET (iSCSI) DEVICES THROUGH SINGLE HOST BUS ADAPTER - An apparatus comprising an interface, a first port, and a second port. The interface may be configured to connect to a host computer. The first port may be configured to connect to a first set of storage devices using a first protocol. The second port may be configured to connect to a second set of storage devices using a second protocol. The apparatus may provide support for the first protocol and the second protocol to allow communication using both the first protocol and the second protocol through the interface. | 11-01-2012 |
20120317316 | SYSTEM TO MANAGE INPUT/OUTPUT PERFORMANCE AND/OR DEADLOCK IN NETWORK ATTACHED STORAGE GATEWAY CONNECTED TO A STORAGE AREA NETWORK ENVIRONMENT - An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate a plurality of intermediate signals in response to a plurality of input/output requests. The second circuit may be configured to generate a plurality of processed input/output requests in response to the plurality of input/output requests. The processed input/output requests may be configured to be processed by a drive controller to access a drive array in accordance with a protocol used to process the input/output requests. | 12-13-2012 |
20150067188 | SYSTEMS AND METHODS FOR MULTI-PROTOCOL TRANSLATION - This disclosure relates generally to communication network protocols, and more particularly to systems and methods for multi-protocol translation. In one embodiment, a multi-protocol translation method is disclosed, comprising: receiving, at a storage area network switch, a frame formatted according to a first protocol; selecting, using the received frame, a second protocol from a plurality of protocols according to which to convert the received frame; obtaining a protocol format specification data of a second protocol; converting by the storage area network switch, the received frame to a converted frame according to the second protocol based on the protocol format specification data of the second protocol; and providing, by the storage area network switch, the converted frame. | 03-05-2015 |
20150142997 | METHODS FOR FRAME ORDER CONTROL AND DEVICES IN STORAGE AREA NETWORK - A method, non-transitory computer readable medium, and device that sends an outgoing storage device frame to a storage device, the outgoing storage device frame converted from an incoming storage device frame received from a host device based on a protocol supported by the storage device. An incoming host device frame is received from the storage device in response to the outgoing storage device frame. Whether an outgoing host device frame has been sent to the host device is determined, the outgoing host device frame converted from the incoming host device frame based on a protocol supported by the host device, wherein the protocol supported by the host device requires a different frame sequencing than the protocol supported by the storage device. A next incoming storage device frame received from the host device is retrieved when the outgoing host device frame is determined to have been sent to the host device. | 05-21-2015 |
