  • Page object caching for variably sized access control lists in data storage systems
    Patent number: 8352497
    Abstract: Technologies are described herein for caching variably sized access control lists (ACLs) in a data storage system utilizing page object caching. A request to access a file is received. An inode number of the requested file is identified. A hash key based on the inode number and a predefined hash value is determined. A determination is made as to whether the hash key is contained in a hash list. In response to determining that the hash key is contained in the hash list, access to a page object in the memory is provided. The page object contains an access control list (ACL) associated with the requested file. The ACL is retrieved from the page object.
