The SPARC Enterprise series is a range of UNIX server computers based on the SPARC V9 architecture. It was co-developed by Sun Microsystems and Fujitsu, announced on June 1, 2004, and introduced in 2007. They were marketed and sold by Sun Microsystems (later Oracle Corporation, after their acquisition of Sun), Fujitsu, and Fujitsu Siemens Computers under the common brand of "SPARC Enterprise", superseding Sun's Sun Fire and Fujitsu's PRIMEPOWER server product lines. Codename is APL (Advanced Product Line).
Since 2010, servers based on new SPARC CMT processors (SPARC T3 and later) have been branded as Oracle's SPARC T-Series servers, the "SPARC Enterprise" brand being dropped. Fujitsu continued to sell SPARC T-Series as their SPARC Enterprise product line until December 2015. Fujitsu rebranded the product line to "SPARC Servers" since SPARC M10 released in 2013 and continued to sell SPARC M-Series and T-Series with their new brand.
