Sun Microsystems Enterprise 250
Sun Enterprise is a range of UNIX server computers produced by Sun Microsystems from 1996 to 2001. The line was launched as the Sun Ultra Enterprise series; the Ultra prefix was dropped around 1998. These systems were based on the 64-bit UltraSPARC microprocessor architecture and related to the contemporary Ultra series of computer workstations. Like the Ultra series, they ran the Solaris Operating Environment. Various models, from single-processor entry-level servers to large high-end multiprocessor servers were produced. The Enterprise brand was phased out in favor of the Sun Fire model line from 2001 onwards.
The Sun Enterprise 450 was a popular rack-mountable entry-level multiprocessor servers launched in 1997, capable of up to four UltraSPARC II processors. The Sun Enterprise 250 was a two processor version launched in 1998. These were later joined by the Enterprise 220R and Enterprise 420R rack-mount servers in 1999. The 220R and 420R models were respectively based on the motherboards of the Ultra 60 and Ultra 80 workstations. The 250 was replaced by the Sun Fire V250, the 450 by the Sun Fire V880. The 220R was superseded by the Sun Fire 280R and the 420R by the Sun Fire V480.
