METHOD, DEVICE AND COMPUTER PROGRAM PRODUCT FOR LOCKING A STORAGE AREA IN A STORAGE SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17988979 Titled 'METHOD, DEVICE AND COMPUTER PROGRAM PRODUCT FOR LOCKING A STORAGE AREA IN A STORAGE SYSTEM'
Simplified Explanation
The abstract describes techniques for locking a storage area in a storage system that consists of two storage nodes. When a data access request is received by either of the nodes, the value of a counter at that node is adjusted. If the ratio of the first node's counter value to the second node's counter value exceeds a certain threshold, a lock flag is allocated to the first node, indicating that it has locked the storage area. This helps to reduce the storage resources required by nodes that are accessed more frequently, improving the efficiency of stripe lock reduction.
Original Abstract Submitted
Techniques lock a storage area in a storage system including a first storage node and a second storage node. Such techniques involve adjusting a value of at least one of a first counter at the first node and a second counter at the second node in response to receiving a data access request for the storage area at at least one of the first node and the second node. Such techniques further involve allocating a lock flag to the first node in response to a ratio of the value of the first counter to the value of the second counter being greater than a first threshold, the lock flag indicating that the storage area is locked by the first node. Accordingly, storage resources required by nodes that are accessed more frequently in statistics are effectively reduced, and the efficiency of applying stripe lock reduction are improved.
