Hitachi has unveiled updates to a pair of blade servers which it promises will help companies meet carbon reduction targets.

The BladeSymphony 2000 and BladeSymphony 320 are built on Intel's Xeon 5500 Series Nehalem processor, which is specifically designed to offer a very high performance per watt.

"Chief information officers are under increasing pressure to slash carbon emissions and overall IT costs," said Ravi Ahluwalia, head of business development at Hitachi's European Systems Solutions division.

"The BladeSymphony 2000 and 320 servers enable businesses to meet these needs by cutting the power use of their datacentre, whilst taking advantage of the latest processing capabilities to run business-critical applications at the highest performance level."

The BladeSymphony 2000 now boasts 144GB of memory, and the server's bandwidth has been increased to help ensure that virtualised environments have the necessary resources. The platform maintains a high server density, and eight blades can be squeezed into each 10U chassis.

The update to the BladeSymphony 320 sees the addition of the Nehalem processor and an increase in memory accommodation.

Both new blades are available now across Europe through Hitachi's network of European distributors.
