Patent number: 8805902Abstract: Various embodiments of the invention relate to an apparatus and a method of managing a snapshot storage pool (SSP) associated with a storage unit of a distributed data storage system. One apparatus includes a logic module and a processor. The logic module is adapted to provide a threshold corresponding to a ratio between a current amount of storage resources used for storing snapshots in the SSP and a total storage capacity defined for the SSP. The processor is adapted to trigger an action that may be effective for managing the SSP in response to the amount of storage resources used for storing snapshots in the SSP crossing the threshold.Type: GrantFiled: September 25, 2012Date of Patent: August 12, 2014Assignee: International Business Machines CorporationInventors: Yaron Revah, Shemer Schwartz, Efri Zeidner, Ofir Zohar

Patent number: 8452899Abstract: A method for data distribution, including distributing logical addresses among an initial set of devices so as provide balanced access, and transferring the data to the devices in accordance with the logical addresses. If a device is added to the initial set, forming an extended set, the logical addresses are redistributed among the extended set so as to cause some logical addresses to be transferred from the devices in the initial set to the additional device. There is substantially no transfer of the logical addresses among the initial set. If a surplus device is removed from the initial set, forming a depleted set, the logical addresses of the surplus device are redistributed among the depleted set. There is substantially no transfer of the logical addresses among the depleted set. In both cases the balanced access is maintained.Type: GrantFiled: December 15, 2011Date of Patent: May 28, 2013Assignee: International Business Machines CorporationInventors: Ofir Zohar, Yaron Revah, Haim Helman, Dror Cohen

Patent number: 8214588Abstract: A method for data mirroring including receiving a sequence of transactions at a first storage node from a host indicating data to be stored by the node, storing the data therein, and delineating a first batch of the transactions. The node returns to the host an acknowledgment of having stored the data, delineates a second batch of the transactions received subsequent to the acknowledgment, and conveys the data to a second storage node. The first node also conveys to the second node a first record of the transactions in the first batch and a second record of the transactions in the second batch, and the data are stored in the second node responsively to the first and second records, so that all data indicated by the transactions in the first batch are stored by the second node prior to storing data indicated by the transactions in the second batch.Type: GrantFiled: November 5, 2003Date of Patent: July 3, 2012Assignee: International Business Machines CorporationInventors: Ofir Zohar, Yaron Revah, Haim Helman, Dror Cohen, Shemer Schwartz

Patent number: 7877546Abstract: Upon receiving a request for one or a set of data blocks associated with a given data segment, a disk cache controller may retrieve into cache the some part of the entire data segment from a disk. Each data segment on a disk may include a fixed number of data blocks, and all data segments may include the same number of data blocks. Data segments may be dynamically defined and their locations and sizes may vary from segment to segment. Data segments may be defined when data is written to the disk, or may be defined at a later point. A table associated with a cache controller may store information as to the physical location or address on a disk of the starting point and/or size of each data segment.Type: GrantFiled: August 9, 2004Date of Patent: January 25, 2011Assignee: International Business Machines CorporationInventors: Ofir Zohar, Yaron Revah, Haim Helman, Dror Cohen, Shemer Schwartz

Patent number: 7870334Abstract: A storage system, consisting of one or more data storage logical units (LUs) formed in physical media. The LUs are adapted to receive command and respond to the commands to store and recall data. The storage system further includes a plurality of ports, each port being adapted to maintain a respective LU command queue for each of the LUs, such that upon receiving a command directed to one of the LUs, the port places the received command in the respective LU command queue. The port converts the received command to one or more converted commands at least some of which are directed to the physical media of the one of the LUs. The port then conveys the commands directed to the physical media in an order determined by the respective LU command queue.Type: GrantFiled: November 12, 2003Date of Patent: January 11, 2011Assignee: International Business Machines CorporationInventors: Ofir Zohar, Yaron Revah, Haim Helman, Dror Cohen, Shemer Schwartz

Patent number: 7836250Abstract: A method for operating a data storage system that includes a plurality of mass storage devices, which are configured to store data redundantly, the method including determining a characteristic service level of one or more of the mass storage devices and defining a reduced service level, which is less than the characteristic service level. The method further includes performing the following steps automatically: detecting the reduced service level on a first mass storage device in the data storage system; determining that data on the first mass storage device is stored redundantly on a second mass storage device in the data storage system; and in response to detecting the reduced service level, diverting an input/output (IO) request for the data directed to the first mass storage device to the second mass storage device, while operating the first mass storage device at the reduced service level.Type: GrantFiled: July 15, 2005Date of Patent: November 16, 2010Assignee: International Business Machines CorporationInventors: Ofir Zohar, Yaron Revah, Haim Helman, Dror Cohen, Shemer Schwartz
