The HP ExSO portfolio features a new lightweight, modular systems architecture. The company claims that the portfolio enables to save more than $152.8 million in reduced capital expenditures and $13.7 million in energy costs.

At the core of the HP ExSO portfolio is the HP ProLiant SL server family, which uses a "skinless" systems architecture that replaces the traditional chassis and rack form factors with an extremely lightweight rail and tray design. HP ProLiant SL portfolio, can cut acquisition costs by 10 percent and power draw by 28 percent.

Rajesh Dhar, director, Industry Standard Servers, Technology Solutions Group, HP India, said: "Customers with scale-out business models need solutions that make every dollar, watt and square foot in the data centre count. The HP ProLiant SL offers pioneering customers like these the most significant design innovation since the blade form factor, allowing them to achieve an economy of scale never before possible."

Michelle Bailey, research vice president, IDC, said: "Businesses built on extreme scale-out environments, such as cloud, Web 2.0 and HPC, operate at maximum transaction volume and low margins. These customers have very distinct and unique data centre requirements, specifically around energy efficiency, cost and time to market.

HP's existing scale-out computing portfolio includes the HP ProLiant DL1000 Multi Node servers, introduced on June 2, the HP POD (Performance Optimized Datacenter), HP StorageWorks 9100 Extreme Data Storage System and the HP ProLiant 2x220c double-density blade server introduced last year.
