In a statement today, the company cited International Data Corp (IDC) figures, which showed that it captured 39 percent of total Unix server spending. No actual figures were provided.
The Asean region comprises Malaysia, Singapore and Thailand, it noted.
IBM had a 23 percent revenue market share, while Hewlett-Packard (HP) had 22 percent.
According to IDC's 2000 server tracker report, Sun came in second in terms of total server revenue. This revenue is generated from the sale of servers based on Unix, Microsoft Windows NT/2000, MVS Mainframe and all other operating systems.
IDC Asia Pacific manager of servers and workstations research Rajnish Arora said in the statement that Sun's success was due to, among other factors, "an extremely aggressive pricing strategy and solid brand equity in the Internet and telecom space".
"Sun's strong focus on high growth segments such as telecom and government, and key wins in the finance segment helped to fuel its growth in 2000," he observed.
The company took a step further by posting a 62 percent growth in worldwide total server shipments last year compared with 1999. It also saw a 43 percent growth in revenue.
