The linchpin of those alleged lower operating costs is more efficient power consumption and fewer people (or at least hours) required to keep the machines humming. According to John Gromala, director of marketing for HP's Industry Standard Servers (ISS) unit, the ROI on a G6 server is as little as 90 days and many business "can be net positive in 90 to 120 days. If people can be more aggressive replacing single core [servers] and even older dual core servers, and get them out of the data center, they improve the efficiency. Those 3 to 5 year-old, single-core servers that people may be thinking about extending the life of, they should take a second look at economics; the dollars they'll spend to keep it running would buy them a new server in 2 months to a year."
Not surprisingly, Intel Nehalem processors are in play with the G6 line of blade, rack, and tower servers. In application, that means twice the memory and storage of previous generations and a claimed 200% boost in performance. HP's also includes an automated migration wizard, a menu of available services, and flexible financing program (with a leaseback options).
As to the power savings, the servers includes sensors to optimize cooling, a common power slow (so you're not locked in a proprietary power supply), and dynamic power capping that limits server energy draw. The keys to the claims of reducing operational support rest in the automation capabilities, including an administrator function that seeks to simplify setup and allow remote access even when the server's offline. There's also a management console for remote or onsite monitoring, and a 10Gb Ethernet network port alleged to ease deployment of virtual machines.
