Cleversafe to combine cloud storage software, Hadoop
Cleversafe Inc. last week said it would enable
Cleversafe 3.0, due out in the fourth quarter, will combine Hadoop MapReduce with the Cleversafe Dispersed Storage Network (dsNet) system. Cleversafe will replace the Hadoop Distributed File System (HDFS) with the Cleversafe information dispersal algorithm, which uses one instance of data across a network of storage nodes.
The ability to replace HDFS comes from an API that makes it seem like the storage system is talking directly to HDFS, and allows the storage software to assign jobs to stores for local data access.
The integration is designed to eliminate the scalability and reliability limitations of Hadoop that make it a poor fit for networked storage.

Overland Storage aims SnapSAN at high end
Overland Storage last week made a move for the high end of the midrange and the enterprise with its latest SnapSAN storage arrays, including solid-state drives (SSDs) and management features such as thin provisioning, automated tiering and caching, and volume cloning.
Both systems scale to 288 TB, support volume cloning, thin provisioning, remote replication, snapshots and a disk spin-down capability. The SnapSAN 5000 includes more advanced features, such as AutoCache for SSDs, AutoTune for performance analysis and AutoTier for automated data movement to different drive classes. The SnapSAN 5000 also has WORM capabilities for compliance.
Both arrays also support SAS and Nearline SAS drives, as well as SSDs.
Although a relative newcomer in the storage area network (SAN) market, Overland is positioning the new systems as low-cost alternatives to midrange and enterprise storage systems from EMC, NetApp, Hitachi Data Systems (HDS), Hewlett-Packard, Dell and IBM.

Nasuni adds block capabilities to cloud storage appliance
Nasuni launched in 2010 with a NAS cloud storage appliance and is now offering iSCSI capability to go with NFS and CIFS support. It is also adding a larger controller to make it easier for customers who want block and file storage in one box.
A Nasuni controller is placed on a customer's site that works as a translator so data can be stored in the Amazon S3 or Microsoft Azure cloud. Nasuni's controller is available on a hardware appliance or as a software virtual appliance that customers can install on any hardware.

EMC launches NetWorker 8 with Client Direct, multi-tenancy
EMC last week rolled out the most significant enhancements to its NetWorker backup software since 2003, revising the architecture so it no longer requires a media server and adding multi-tenancy for cloud backup.
"We made fundamental architectural changes to support backup to disk," Rob Emsley, EMC's senior director of product marketing for backup products, said of NetWorker 8. "We changed the way backup data flows from backup clients to any disk target."
NetWorker 8 distributes the backup process among application servers. In previous versions, backups were managed through media servers sitting between the application servers and the backup target.
EMC claims its NetWorker's new Client Direct feature can improve backup speeds by up to 50% by backing up directly from the application client to disk without going through a media server.

Quantum tunes up StorNext for 'big data' files
Quantum Corp. is updating its StorNext file management and archiving software to better handle "big data" files. According to Quantum, the product is designed to handle large numbers of files as well as large single files generated by industries that deal with lots of data, including media and entertainment, oil and gas exploration, video surveillance, and life sciences.
Janet LaFleur, StorNext's senior product management manager, said 4.3 is “designed for customers with big data files to manage the velocity, volume and variety of the data they’re hitting."
Quantum claims its restructured database can scale to 1 billion files while creating and truncating files faster than previous versions.
