EMC has announced four new Clariion Disk Library midrange disk-based backup-and-recovery systems with twice the capacity and performance of current systems. The company is also adding new reliability and information protection features to the systems.
"Customers have asked us for something simple that will help them meet their shrinking backup windows and ensure fast, reliable recovery of their information," said Tom Joyce, vice president of EMC storage platforms marketing.
Midrange storage systems have grown much faster than high-end monolithic storage systems such as EMC's Symmetrix, for which the company also released new editions recently.
"Many of the high-end features are trickling down into the midmarket modular offerings and many customers are buying these systems in lieu of the more monolithic systems," said Arun Taneja, analyst at the Taneja Group.
The new Clariion DL310, DL710, DL720, and DL740 scale capacity to 348TB and offer compatibility with ATA disk drives. The new systems are designed with point-to-point connectivity between the disk drives and the storage controllers. That replaces the older FC-AL (Fibre Channel arbitrated loop) architecture and allows for better detection when a disk drive is about to fail.
"This provides much better communication between the disk drives," Teneja said.
Along with the new hardware configuration, the new Clariion systems include active engine fail-over, tape-emulation software that provides reliability via engine fail-over features, and improved performance through write-cache consolidation. New software enhancements allow for easier data movement between the core of the network and its edge and remote locations, EMC officials said.
The new Clariions are now interoperable with StorageTek's PowderHorn, Sony PetaSite, and ADIC i2000 tape libraries, enabling users to incorporate a Clariion into existing backup environments. Clariion already supports Quantum ATL P-Series and ATL 7100, StorageTek L-Series, and IBM 3590 and 3584 tape libraries.
Aside from additional capacity and speed, this crop of Clariions includes new UltraPoint Technology that allows for point-to-point connectivity between disk drives and controllers. The systems also include new Virtual LUN (logical unit number) technology that allows users to move data volumes within their system without affecting applications.
EMC has also improved replication capabilities in its SnapView and MirrorView software products by adding support for consistency groups to maintain data coherency across multiple volumes during point-in-time backups and remote copying. Those were features previously available in the higher-end Symmetrix line. EMC also doubled the number of LUNs that can be copied, from 50 to 100 in MirrorView and from 100 to 200 in SnapView.
Moreover, EMC announced that it will begin to offer storage security products through agreements with several storage vendors already in that market, such as Decru, NeoScale and CipherOptics.
Storage security products from Decru and NeoScale encrypt information at wire speeds without a performance hit. Decru and NeoScale devices protect data that rests behind a firewall, while CipherOptics protects data in-flight on a network.
Ironically, Decru was recently acquired by EMC rival Network Appliance. However, the company will remain a separate business unit at NetApp, which will keep the two rivals at a comfortable distance. -- InfoWorld (US)
