Abstract
A method is used in managing global caches in data storage systems. A cache entry of a global cache of a data storage system is accessed upon receiving a request to perform an I/O operation on a storage object. The cache entry is associated with the storage object. Accessing the cache entry includes holding a reference to the cache entry. A determination is made as to whether the I/O operation is associated with a sequential access. Based on the determination, releasing the reference to the cache entry is delayed.
