Computer
Rooms Feel the Heat (Subscription Required),
Wall Street Journal
Companies and institutions are exploiting the new power of
video, fancy Web graphics and expanded data storage, and they
also are finding an old problem has come back: The servers
that do those tasks are getting too hot to handle for some
computer rooms.
Today's powerful computers may be more cost-effective and
typically don't take up any more space than the machines they
replace, but they produce far more heat. Since 2000, the average
power per watt in data centers -- a measure of how much heat
computers generate -- has, in some cases, quadrupled to more
than 200 from about 50, industry officials said. |
