Abstract
A redundant array of independent nodes are networked together. Each node executes an instance of an application that provides object-based storage. The nodes are grouped into systems each having multiple nodes. Objects in the systems have access control lists (ACLs) associated therewith. A method of providing a search key to each ACL in any one system comprises: selecting a region for each metadata object pertaining to the objects in the system; and generating, for each ACL associated with an object in the system, an ACL ID (identifier) as a search key which includes the region number of the region selected for the metadata object pertaining to the object, a region map level corresponding to the region selected, and a monotonically increasing counter value that is automatically incremented each time an ACL ID is generated. The ACL ID remains unique during reconfiguration via splitting/merging existing distributed portions of the database.
