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 |
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 |
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 |
20120290630 | SCALABLE STORAGE FOR VIRTUAL MACHINES - A method and system is disclosed for providing storage services to Virtual Machines (VMs) and the Hypervisor Platforms that host them. NAS referrals are used to control selection of NAS proxy servers that are optimized for the support of VMs and the Hypervisor Platforms accessing directories that are exclusively used in conjunction of a single VM. Referrals are dynamically controlled in a manner specific to the target environment to provide an optimal combination of local and network storage in support of VMs. A method of using named attributes allows referrals to subsets of a directory. The overhead of using a NAS proxy is tailored to the smallest set of accesses required to gain beneficial result from the use of local storage, and using direct access to shared network storage when local storage is not allocated. Most of the new suggested techniques are transparent to the existing NAS clients; some techniques may require modification of the NAS client software. | 11-15-2012 |
20130041872 | CLOUD STORAGE SYSTEM WITH DISTRIBUTED METADATA - A method and system is disclosed for providing a cloud storage system supporting existing APIs and protocols. The method of storing cloud storage system (CSS) object metadata separates object metadata that describes each CSS object as a collection of named chunks with chunk locations specified as a separate part of the metadata. Chunks are identified using globally unique permanent identifiers that are never re-used to identify different chunk payload. While avoiding the bottleneck of a single metadata server, the disclosed system provides ordering guarantees to clients such as guaranteeing access to the most recent version of an object. The disclosed system also provides end-to-end data integrity protection, inline data deduplication, configurable replication, hierarchical storage management and location-aware optimization of chunk storage. | 02-14-2013 |
20130185258 | UNIFIED LOCAL STORAGE SUPPORTING FILE AND CLOUD OBJECT ACCESS - A method and system for providing unified local storage support for file and cloud access is disclosed. The method comprises writing a chunk on a storage server, and replicating the chunk to other selected storage servers when necessary. The method and system further comprise writing a version manifest on the storage server; replicating the version manifest to other selected storage servers when necessary. Object puts or appends are implemented by first chunking the object, determining if the chunks are new, transferring the chunks if required, followed by creation of a new version manifest referencing the chunks. Finally, the method and system include providing concurrent file-oriented read and write access consistent with the stored version manifests and chunks. | 07-18-2013 |
20140025948 | SYSTEM AND METHOD FOR DISTRIBUTED DEDUPLICATION OF ENCRYPTED CHUNKS - The present disclosure relates to an advantageous system and related methods for distributed deduplication of encrypted chunks. One embodiment relates to a method for storing encrypted chunks in which an encryption key is generated independently from a chunk payload. With this method, two encrypted chunks are identifiable as having identical chunk payloads even when the chunk payloads are encrypted with different encryption keys. Other embodiments, aspects and features are also disclosed. | 01-23-2014 |
20140258616 | 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. | 09-11-2014 |
