Quantum Boosts DXi8500 Backup With 3 TB Drives

By Pedro Hernandez

New 3 TB drive option and security enhancements raises the bar for the company's disk-based backup systems.

Quantum is rolling out new updates to its DXi8500 disk backup system that promise new levels of storage density, improved security and energy savings -- all in a smaller footprint. A tall order, but the company is confident it has delivered the "most efficient enterprise backup and dedupe solution," said Eric Bassier, director of Product Marketing for Quantum.

The storage company is on an efficiency kick of late. Last month, Quantum set out to speed big data storage with updates to StorNext, the software that governs its file sharing and archiving appliances, that included a major database restructure.

Key to the DXi8500's new efficiency gains, however, is the inclusion of 3 TB drives from Hitachi and Seagate "for some pretty impressive gains in storage density and energy savings," stated Bassier. Not only do the capacious new hard drives help improve storage density by 50 percent, they are the "lynchpin to a number of enhancements," he informs.

One benefit is improved security. The self-encrypting drives protect data in the case of physical drive removal. The company's DXi Accent software secures data in transit using the AES 256-bit standard, and it reduces network bandwidth requirements by deduplicating data on the host. Also new is support for Key Management Interoperability Protocol (KMIP), which extends to all of the company's Scalar libraries.

It's all part of Quantum's end-to-end encryption strategy for fashioning a secure backup storage foundation. This is the company's way of providing "flexible and sophisticated options for protecting data," said Bassier, like "the ability to encrypt the data during replication," for example.

Performance gets a boost with the new drives, making it possible for the system to achieve data transfer rates of more than 11 TB per hour. The new drives can also keep a lid on energy costs.

The energy savings achieved by adopting the new drives are considerable, according to Quantum. By the company's estimates, customers can see a 42 percent reduction in energy costs. With the 3 TB drives, a 330 TB system now takes up less data center real estate -- one rack versus two -- and it consumes approximately 4000 kWh versus 7000 kWh for prior configurations.

All told, Quantum's work on the DXi8500 should find a receptive audience among organizations struggling with backup systems performance, efficiency and costs, according to Russell Fellows, senior partner, Evaluator Group. "Quantum's enhancements to their DXi8500 platform address these concerns by increasing capacity and density, reducing required power and cooling while also improving performance," he said in a statement.

The new drives do more than provide a capacity bump. "With Quantum's enhancements and 3 TB drives, the DXi8500 helps enterprises meet increasingly difficult data protection needs with tight budgets," added Fellows.

Quantum's DXi8500 with 3 TB drives are available for ordering now.
