摘要： The presently disclosed subject relates at least to a method and system for controlling access to a logical unit (LU) in a logical storage space, available to a given initiator, representing a corresponding physical storage space, said logical storage space being accessible via a storage control layer, said storage control layer being associated with a security manager. A first value is generated by the security manager, based on a secret key, and transmitted to host requesting permission to access the logical storage space, while the secret key is made available to a target associated with the logical storage space. The host sends to the control device an access related request, the request comprising a second value which was generated based on the first value. Responsive to the command the target calculates the first value, based on the secret key and the second value based on the first value. The second value is validated with the help of said secret key and the respective access is allowed in case the second value is validated.

摘要： There is provided a method of operating a multipath storage system, the method comprises: identifying a primary storage control port configured to be responsible for a given LBA range and a secondary storage control port configured to have secondary responsibility for the given LBA range; reducing, in a manner unaffecting respective inbound I/O operation, outbound I/O operation related to the given LBA range and occurring at the primary storage control port, thereby causing a situation requiring switching all respective I/O requests to an alternating path; analyzing responsive changes in outbound I/O operation related to the given LBA range and occurring at the secondary storage control port, and verifying operability of switching to the alternating path in accordance with the obtained results. Outbound I/O operation can be reduced with the help of a routine configured to identify inbound I/O requests directed to the given LBA range and to put these requests on hold for a delay period, thus giving rise to delayed I/O requests, wherein the delay period is configured to be long enough to enable switching to an alternating path.

摘要： A method for providing a warranted snapshot that may include: receiving a request to create a first warranted snapshot of a first logical volume at a first point in time and creating the first warranted snapshot if the first warranted snapshot is non-writable and if an amount of physical storage actually devoted by a storage system to the first logical volume at the first point of time does not exceed a size of a free physical storage space that is available for storing any future data delta associated with the first warranted snapshot. The creating of the first warranted snapshot may include allocating a first virtual portion of a physical storage space for storing any future data delta associated with the first warranted snapshot. A size of the first virtual portion equals the amount of physical storage actually devoted to the first logical volume at the first point of time.

摘要： A method and system is disclosed for storage optimization of thin provisioning. Non-zero data units within data portions are re-allocated to specifically designated one or more areas in the physical storage space and the physical address of the non-zero data unit within the designated area is associated with the logical address of the non-zero data unit. In case the data portion is allocated to the physical storage, the physical storage space initially allocated to the data portion is returned to the pool of available physical storage space, thereby freeing the storage space for storing other data.
