The Sun Ultra 25: A Single-Processor Successor

Sun Microsystems released the Ultra 25 in 2006 alongside the dual-processor Ultra 45. Sharing much of the Ultra 45's design, it was sold as a lower-cost option for users who did not require multiprocessing.

The workstation used a single 1.34 GHz UltraSPARC IIIi processor with integrated memory and I/O controllers. While slower than contemporary x86 CPUs, it ran Solaris and SPARC-based software.

The machine used the same tower chassis as the Ultra 45. It supported multiple SATA or SAS hard drives, up to 8 GB of RAM, and included PCI Express and PCI-X slots for add-in cards like graphics accelerators.

It ran Solaris 10. Sun marketed the system to technical professionals, developers, and enterprise users invested in the Solaris ecosystem. The Ultra 25 and Ultra 45 were the last generation of SPARC workstations designed in-house by Sun as the market shifted toward x86 hardware.
