Abstract: Method, apparatus and product for data cloning in a memory-based file systems. A content of each object of the file system is retained in data units and represented using a tree of the nodes comprising tree nodes and leaf nodes. The file system utilizes a volatile resource usage collection and volatile reference counters for each node of the nodes. In response to mounting the file system, a storage retaining a file system metadata is scanned to compile the volatile resource usage collection and the volatile reference counters. In response to a determination to reuse a pointed node of a tree of an object by a pointing node, a volatile reference counter of the pointed node is updated and the pointing node is atomically set, using a single instruction, to point to the pointed node.

Abstract: Logical mirroring of an initiator server running a memory aware file system to a multi-tiered target server by receiving at a first tier of the target server data that was modified at the initiator server and retaining at the first tier of the target server a first subset of the data and moving to a second tier of the target server a second subset of the data to efficiently utilize the multi-tiered target server.

Abstract: Methods for data placement in a memory-based file system are described, including copying a user data unit from a second storage type device to a first storage type device based on an access request to the file system, the first storage type device being a faster access device than the second storage type device, referencing the user data unit in the first storage type device by a byte addressable memory pointer, and using the byte addressable memory pointer to copy the user data unit from the first storage type device to the second storage type device based on data access pattern.

Abstract: Managing pages in a memory based file system by maintaining a memory into two lists, an Lr list and an Lf list, moving pages from the Lr list to the Lf list based on a repeated access pattern, and moving a page out of the Lr list or the Lf list arbitrarily, thereby enabling the two lists to re-grow according to current workload.
