Google Search Appliance

The Google Search Appliance (GSA) is a discontinued series of rack-mounted servers with search engine indexing software.

The GSA operating system was based on CentOS. The software was produced by Google and the hardware was manufactured by Dell. The final 2009 GSA version was based on Dell's PowerEdge R710. Google announced the phase out of the GSA in early 2016 and a complete discontinuation by 2019.

The GSA was supplied in two models: a 2U model (GB-7007) capable of indexing up to 10 million documents, and a 5U (2U plus 3U storage) model (GB-9009) that was capable of indexing up to 30 million documents. Sales were operated on a licensing scheme which started as a two-year contract for maintenance, support and software updates.

The GSA contained Google search technologies and a means of configuring and customizing the appliance.

The GSA was first introduced in 2002.

Software version 6.0 was released in June, 2009. This software ran on some hardware versions of the GB-1001 model (all units with an "S5" prefix in their "Appliance ID"), and all GB-7007 and GB-9009 models.

Google released version 7.0 on October 9, 2012 and version 7.2 on February 11, 2014.

The GSA could be purchased in two separate versions based on the number of documents being indexed. Model G100, a 2U appliance, could index up to 20,000,000 documents. The G500 5U appliance could index up to 100,000,000 documents.
