20090287967 | Resilient Data Storage in the Presence of Replication Faults and Rolling Disasters - A method for data protection includes, in a first operational mode, sending data items for storage in a primary storage device and in a secondary storage device, while temporarily caching the data items in a disaster-proof storage unit and subsequently deleting the data items from the disaster-proof storage unit, wherein each data item is deleted from the disaster-proof storage unit upon successful storage of the data item in the secondary storage device. | 11-19-2009 |
20100049919 | SERIAL ATTACHED SCSI (SAS) GRID STORAGE SYSTEM AND METHOD OF OPERATING THEREOF - There is provided a SAS grid storage system and a method of operating thereof. The system comprises a) a storage control grid comprising a plurality of interconnected data servers operable in accordance with at least one SAS protocol and b) a plurality of disk units adapted to store data at respective ranges of logical block addresses (LBAs), said addresses constituting an entire address space. Each disk unit comprises at least one input/output (IO) module comprising at least one internal SAS expander configured as a target with regard to the storage control grid. The plurality of disk units is operatively connected to the storage control grid in a manner enabling to each data server comprised in the storage control grid an access to each disk unit among the plurality of disk units. The method of operating the grid storage system comprises: a) assigning each LBA to a primary data server configured to have a primary responsibility for permanent storing of data and/or metadata related to the desired LBA, a secondary data server configured to take over the responsibility for said permanent storing in an event of a failure of the primary data server, and, optionally, to auxiliary secondary data server configured to take over the responsibility for said permanent storing in an event of a failure of the secondary data server; b) responsive to an I/O requests directed to a certain LBA, temporarily storing the data and metadata with respect to desired LBA in the primary data server; c) sending copies of said data/metadata from the primary data server to respective secondary data servers for temporarily storing; and d) sending permissions from the primary data server to the secondary data servers to delete the copy of data/metadata upon successful permanent storing said data/metadata. | 02-25-2010 |

20100172084 | Disaster-Proof Storage Unit Having Transmission Capabilities - A storage device includes a memory and a wireless transmitter, both contained in a disaster-proof enclosure. The memory is configured to receive and store data, and the wireless transmitter is coupled to read and transmit the data from the memory. The disaster-proof enclosure is surrounded by a thermally-insulating layer, and is configured to protect the memory and the transmitter from environmental conditions caused by a disaster event, such that the memory and the wireless transmitter remain functional during and after the disaster event and the transmitter is able to transmit at least a portion of the data to a receiver from within the disaster-proof enclosure after the disaster event. | 07-08-2010 |
20110208914 | STORAGE SYSTEM AND METHOD OF OPERATING THEREOF - There are provided a storage system, storage control unit and method of operating thereof. A storage system comprises a permanent storage subsystem comprising a first cache memory and a non-volatile storage medium, and a storage control unit operatively coupled to said subsystem and to a second cache memory operable to cache “dirty” data pending to be written to the permanent storage subsystem and to enable, responsive to at least one command by the control storage unit, destaging said “dirty” data or part thereof to the permanent storage subsystem. The storage control unit is operable to determine achievement of a “writing criterion”, to provide, upon achieving, at least one command to the permanent storage subsystem requiring flushing destaged data or part thereof from the first cache memory to the non-volatile storage medium, and to provide at least one command to the second cache memory requiring reclassification of the “washed” data or a respective part thereof into the “clean” data, wherein the storage control unit is further operable to configure the “writing criterion” responsive to indicating one or more predefined events during an operation of the storage system. | 08-25-2011 |

20120124311 | Data Gap Management in a Remote Data Mirroring System - A method includes monitoring a sequence of transactions in one or more volumes. The transactions are transferred to a primary storage ( | 05-17-2012 |
20120259961 | SYSTEM OF MANAGING REMOTE RESOURCES - A system of managing remote resources that includes a local storage associated with a local storage manager constituting a local storage system. A remote storage associated with a remote storage manager constituting a local storage system. The local storage system is associated with a remote storage system by means of a first link. The local storage system is configured to send through the first link I/O remote commands complying with the SCSI protocol, for execution in the remote storage system. The system includes a second link associating the local storage system and the remote storage system. The local storage manager being responsive to remote storage management commands and being configured to send through the second link corresponding cross-storage-remote management commands that comply with the SCSI protocol, for execution in the remote storage. | 10-11-2012 |

20130311736 | DISASTER-PROOF DATA RECOVERY - A recovery unit for recovering data includes an antenna and a first wireless transceiver. The first wireless transceiver is configured to communicate via the antenna only with a second wireless transceiver of a storage unit that holds records associated with the data. When an event damaging at least some of the data occurs and the recovery unit is brought into proximity with the storage unit, the recovery unit receives the records from the storage unit for recovery of the data. | 11-21-2013 |
20150032980 | Storage System and Method for Accessing Logical Volumes - A method and a storage system are provided for accessing volumes. The storage system provisions to a host, a place holder handle configured for allowing access to any volume selected by the host and allowed to be accessed by the host. The volume forms part of accessible volumes included in the storage system. The storage system receives from the host a first request for associating the place holder handle with a first selected volume from among the accessible volumes and enables the host to access the first selected volume in response to receiving an access request indicative of the place holder handle. | 01-29-2015 |
