Ultra 2 workstation's balanced architecture removes performance limitations and bottlenecks so the full power of both UltraSPARC-II processors are unleashed. The Ultra 2 workstation's high-speed memory system supports up to two gigabytes of RAM, a single Creator3D or Elite3D m6 graphics adapter, and multiple disk arrays on a Fast-Wide SCSI bus. Four SBus slots provide room to grow with an extensive collection of Sun and third party cards. With dual processors and multi-threaded Solaris, you get fast results. And the support for multiple graphics accelerators makes it easier to gain insights into problems and interpret large data sets. Ultra 2 is fully binary compatible with all Solaris applications, meaning you can run the same applications up or down the Sun line, and Ultra 2 provides media interchangeability.This system package allows you to upgrade a SPARCstation 4 or 5 to an Ultra 2 1170.
