摘要： A method for synchronizing between a primary control node of a storage system and a secondary control node of the storage system, the method may include performing a change in a key-value store that is stored in shared memory of the storage system and includes control metadata for controlling access to data stored in the storage system; the shared memory is accessible to the primary control node and to a secondary control node; generating a change indication that (i) is indicative of the change in the key-value store and (ii) requests the secondary control node to introduce changes in one or more additional data structures that are not stored in the shared memory; the change in the key-value store comprises replacing a previous given value with a current given value that is associated with a given key; sending the change indication to the secondary control node; receiving an acknowledgement from the secondary control node; wherein the acknowledgement indicates at least one of the following: (i) the secondary control node received the change indication and (ii) the secondary control node introduced the changes in the one or more additional data structures that are not stored in the shared memory; and deleting, by the primary control node, the previous given value from the shared memory.

摘要： A system for managing variable sized pages of possibly non contiguous blocks in a Non-Volatile-Storage (NVS) for attaining a consistent NVS that survives malfunction events. Each page includes a self describing block or linked list of self describing blocks. the system includes: Volatile Storage storing auxiliary modules, means for performing an atomic “create a new page” procedure. Means for performing an atomic write “add block” procedure for adding a possibly non contiguous block to a page. The newly added block has a back pointer to a previous block in the page. Means for performing a “delete page” procedure for deleting all blocks in a page. Means for performing a recovery procedure for rolling backward the add block procedure and rolling forward the delete page procedure, in case of malfunction event, thereby attaining consistent NVS.

摘要： A two-phase process FlashCopy operation is provided that can be used to aid in the formation of consistency groups across multiple storage control units. In the first phase, preparations to create a new consistency group are made “revertible” by write-inhibiting the source volumes through “Establish-FlashCopy-revertible” commands. If the preparation of any volume within the consistency group fails, a “Withdraw-FlashCopy-revert” command may be executed, thereby causing a retention of the prior FlashCopy point-in-time copy. In the second phase, executed if all preparations are successful, a “Withdraw-FlashCopy-commit” command may be executed to remove all write-inhibit indicators, complete the creation of the new FlashCopy point-in-time copy and secure the new consistency group. Write requests to the FlashCopy source volumes may then be received and processed without risking corruption of the new consistency group on the Flashcopy target volumes.
摘要翻译：提供了一个两阶段FlashCopy操作，可用于帮助跨多个存储控制单元形成一致性组。在第一阶段，创建新的一致性组的准备工作通过“建立-FromCopy-revertible”命令写入禁止源卷“可回复”。如果一致性组中的任何卷的准备失败，则可以执行“Withdraw-FlashCopy-revert”命令，从而保留先前的FlashCopy时间点副本。在第二阶段，如果所有准备工作都成功执行，则可以执行“Withdraw-FlashCopy-commit”命令来删除所有禁止写入指示符，完成创建新的FlashCopy时间点副本并确保新的一致性组。然后可以接收并处理向FlashCopy源卷写入请求，而不会在Flashcopy目标卷上新的一致性组的损坏风险。
