A write-once-read-many, WORM, storage system is arranged to store datasets each with associated attributes including a WORM attribute indicating the dataset's WORM status, and to protect from change or deletion WORM datasets, and at least certain of their attributes including those relevant to WORM status. Retention management capabilities are provided for such a storage system, including the ability to set a given dataset for retention for a particular retention period by storing a corresponding retention date in an attribute of the dataset, and setting the WORM attribute to indicate that the dataset is a WORM dataset. Also provided is the ability to determine expiry of the retention period for the given dataset, and then to remove the stored retention date and change the WORM attribute of the dataset to indicate that it is no longer a WORM dataset.

Retention management in a worm storage system

Example embodiments relate to automatic WORM-retention state transitions. In example embodiments, a storage computing device may detect a request to access, via a file system, a file that is associated with a first retention state. The first retention state may indicate either a first type of WORM-retention protection for the file or no WORM-retention protection for the file. The storage computing device may determine, in response to the request, that the file should be designated with a second retention state. The second retention state may indicate a second type of WORM-retention protection for the file. The determination may be based on a retention policy file that is tightly integrated with the file system and metadata of the file. The storage computing device may transition the file (e.g., by communicating with the file system) to be associated with the second retention state instead of the first retention state.

Automatic WORM-retention state transitions

A system and method are disclosed for providing multi-node environment comprising a first node associated with a first operating system; a second node associated with a second operating system, wherein the second operating system is independent of the first operating system; a storage; and an interconnect coupling the first node with the storage and coupling the second node with the storage; and wherein the first node directly accesses the storage and the second node directly accesses the storage.
