"A decade ago, when it was known for little more than web search, Google introduced a bright yellow box that let businesses use the company’s search technology to find stuff stored on their own internal networks. The Google Search Appliance was the company’s first venture into the business world,leading the way for a long list of other enterprise tools, including Gmail and Google Docs and Google Chromebooks.
The GSA — as Google calls it — is now overshadowed by so many other Google hardware and software tools. But the company still believes in its mission. On Tuesday, Google unveiled a new version of the tool — GSA 7.0 — boasting of a new interface, several new search tools, and the ability to handle much larger amounts of data. According to the company, a single rack of these appliances can now juggle the equivalent of the Google.com search index as it stood in the year 2000 — i.e. an index spanning one billion webpages."
