Abstract: Methods, systems, apparatus including computer programming encoded on a computer storage medium for efficiently storing data across memory hierarchy on one or plurality of nodes include creating ordered partitions of data based on key where partition order is achieved using highly space optimized prefix tree index. Within a partition, data is fully or partially ordered based on key. Multiple prefix tree indices are created one for each memory hierarchy and all are stored in fast memory like DRAM.

Distributed data storage systems like databases/key value stores can utilize this data storage mechanism to store and retrieve data efficiently across memory hierarchy on one or plurality of nodes.

Abstract: A cluster of computer system nodes connected by a storage area network include two classes of nodes. The first class of nodes can act as clients or servers, while the other nodes can only be clients. The client-only nodes require much less functionality and can be more easily supported by different operating systems. To minimize the amount of data transmitted during normal operation, the server responsible for maintaining a cluster configuration database repeatedly multicasts the IP address, its incarnation number and the most recent database generation number.

A client-only node uses the IP address of the server to connect to the server, to download the information from the cluster database required by the client-only node and to upload local disk connectivity information.

Abstract: A technique recovers from a low space condition associated with storage space reserved in an extent store to accommodate write requests received from a host and associated metadata managed by a layered file system of a storage input/output (I/O) stack executing on one or more nodes of a cluster. The write requests, including user data, are persistently recorded on non-volatile random access memory (NVRAM) prior to returning an acknowledgement to the host by a persistence layer of the storage I/O stack. Volume metadata managed by a volume layer of the layered file system is embodied as mappings from logical block addresses (LBAs) of a logical unit (LUN) accessible by the host to extent keys maintained by an extent store layer of the layered file system. Extent store metadata managed by the extent store layer is embodied as mappings from the extent keys to the storage locations of the extents on storage devices of storage arrays coupled to the nodes of the cluster.

Abstract: A first block storage device sharing an object storage device with a second block storage device has: plural kinds of physical devices having different access response performances; and a hierarchical logical disk created by using the storage areas of the physical devices and the storage area of the object storage device.

Abstract: A system and method for improving the distribution of data extent allocation in dynamic disk pool systems is disclosed. A storage system includes a storage controller that calls a hashing function to select storage devices on which to allocate data extents when such is requested. The hashing function takes into consideration a weight associated with each storage device in the dynamic disk pool. Once a storage device is selected, the weight associated with that storage device is reduced by a predetermined amount. This reduces the probability that the selected storage device is selected at a subsequent time. When the data extent is de-allocated, the weight associated with the affected storage device containing the now-de-allocated data extent is increased by a predetermined amount. This increases the probability that the storage device is selected at a subsequent time.
