| 20120017043 | METHOD AND SYSTEM FOR HETEROGENEOUS DATA VOLUME - A method and system is disclosed for providing a heterogeneous data storage comprising a plurality of storage devices of different types with respect to device vendor, model, capacity, performance and/or function. The present invention employs data access mechanisms specific to the type of underlying storage and the type of data to be stored or retrieved, and provides for integrated remote mirroring, disaster recovery and hierarchical storage management (HSM), as well as improved I/O performance and life expectancy of storage disks. A method of writing to and reading from heterogeneous data volume is also disclosed. | 01-19-2012 |
| 20120011337 | HETEROGENEOUS REDUNDANT STORAGE ARRAY - A method and system is disclosed for providing fault tolerant data storage with built-in backup capabilities, improved I/O performance, and improved utilization of storage devices. A method for writing data includes receiving request to write a logical block of data to a heterogeneous data volume comprising plurality of storage devices (disks), determining number of copies of the logical block to store and associated classes of disks within the data volume to be used with each copy, processing each copy of the logical block in accordance with properties associated with the corresponding classes of disks within the data volume, determining replication schemes used in the data volume and associated with the specified classes of disks, segmenting the logical block into data blocks and generating additional parity blocks in accordance with the replication schemes, selecting data writing mechanisms in accordance with the classes of disks and using those mechanisms to write the data and parity blocks to the data volume. | 01-12-2012 |
| 20120011176 | LOCATION INDEPENDENT SCALABLE FILE AND BLOCK STORAGE - A method and system is disclosed for resolving a single server bottleneck. Logically associated data is typically collocated within a single filesystem or a single block device accessible via a single storage server. A single storage server can provide a limited I/O bandwidth, which creates a problem known as “single I/O node” bottleneck. The method and system provides techniques for spreading I/O workload over multiple I/O domains, both local and remote, while at the same time increasing operational mobility and data redundancy. Both file and block level I/O access are addressed. | 01-12-2012 |
