For the first time on Wednesday, Google opened up about the innovative design of its custom-built servers.
The timing of the reveal, which coincided with April Fool’s Day, left some wondering if the earth shattering news was a prank. If it sounds too good to be true, it probably is, right? Not so in this case. In the interest of furthering energy efficiency in the industry, Google divulged that each of its servers has a built-in battery design. This means that, rather than relying on uninterruptible power supplies (UPS) for backup power, each of Google’s servers has its own 12-volt battery. The server-mounted batteries have proven to be cheaper than conventional UPS and provide greater efficiency.
Google offered additional insights into its server architecture, its advancements in the area of energy efficiency, and the company’s use of modular data centers. For the full details, I recommend reading Stephen Shankland’s coverage of the event at CNET News. It’s fascinating stuff. Plus, Google plans to launch a site in a few days with more info.
