NEC begins selling server with built-in batteries

Tools

NEC has taken the wraps off a new rack-mounted server that comes with its own internal batteries for backup power in the event of a power outage.

Available in several configurations, the Express5800 server line is powered by Intel (NASDAQ: INTC) Xeon processors and includes an internal nickel-metal hydride battery pack with an option to add a second for extended run times.

The batteries are expected to last about five years and save space, as everything is stored internally. Because the batteries are recharged internally, power usage is also more efficient due to a reduced need to convert between AC and DC voltages.

According to InfoWorld, a single battery can deliver six minutes and 40 seconds of runtime at 100 watts, or 15 minutes and 30 seconds if two batteries are used. At the server's full load of 311 watts, a dual battery setup can provide power for 3 minutes and 40 seconds--which should be sufficient to affect a proper shutdown under most circumstances.

The Express5800 goes on sale this week in Japan, with shipments expected to begin Dec 26. NEC is said to be considering sales of the server internationally, though no decision has been made yet on where and when that will happen.
