Sun Expert3D-Lite PCI graphics accelerator card hangs system (BugID 4474181)

The Sun Expert3D-Lite™ PCI graphics accelerator card (Sun part number X3684A) is not supported in Sun Fire 880 systems. If you use this card on a Sun Fire 880 system, the system may hang under the Solaris Common Desktop Environment when certain windows are resized. In some cases, the system may lock with a black screen and you will be unable to reboot the system.

Note For further information about this issue, see the SunSolve Online web site.

CPU/Memory slot fault LEDs do not light for overtemperature conditions (BugID 4451164)

On Sun Fire 880 systems running the Solaris 8 7/01 or 8 10/01 operating environment, the Fault LED associated with each CPU/Memory board slot does not light in response to a CPU overtemperature condition. However, the front panel System Fault and Thermal Fault LEDs do light under these conditions and the system generates a warning message that indicates which CPU is the source of the problem.

Note Patch 110849-08 or later fixes this issue. See “Required And Recommended Software Patches” on page 3.

SCSI warning when running SunVTS with an attached D1000 disk array (BugID 4482342)

If you use SunVTS 4.4 software on a Sun Fire 880 server that is connected to a Sun StorEdge™ D1000 disk array, the system will generate SCSI warning messages immediately after you invoke SunVTS software. The body of each warning message contains the following text:

Resetting scsi bus, data overrun

These warnings result from a problem in the SunVTS diagnostic code and should not be interpreted as a problem with the server or attached disk array.

Note Patch 111854-01 or later fixes this issue. See “Required And Recommended Software Patches” on page 3.

880 specifications

The Sun Microsystems 880 is a prominent series of workstations and servers that played a significant role in the computing landscape during the late 1980s and early 1990s. It was known for its innovative technologies and robust performance, making it a favored choice for both developers and enterprises. The 880 series was powered by the SPARC (Scalable Processor ARChitecture) architecture developed by Sun, which provided enhanced speed and efficiency.

One of the standout features of the Sun 880 was its multiprocessing capability, allowing multiple processors to work simultaneously. This capability ensured high performance for demanding tasks, making it ideal for applications in scientific research, graphics, and large databases. The architecture supported a wide range of operating systems, with SunOS being the most notable, providing a stable and powerful environment for users.

The Sun 880 also incorporated advanced memory management features, including support for virtual memory, which allowed for more effective use of system resources. Users could run multiple applications simultaneously without compromising system performance. The system architecture was designed to handle large amounts of RAM, which was essential for memory-intensive applications, further enhancing its suitability for professional use.

Another characteristic of the Sun 880 series was its modular design, which allowed for easy upgrades and maintenance. This modular approach meant that users could customize their systems according to their specific needs, whether that involved adding more memory, upgrading processors, or incorporating additional storage solutions. The high flexibility made it appealing to businesses that required tailored solutions.

In terms of connectivity, the Sun 880 featured a variety of ports and interfaces, enabling integration with various peripheral devices. This made it possible to connect printers, scanners, and other essential tools, facilitating seamless operation in office environments.

The Sun 880's impressive combination of processing power, expandability, and superior memory management made it a cornerstone in the evolution of workstations and servers during its time. As technology progressed, the Sun 880 helped pave the way for subsequent generations of computing systems, leaving a lasting legacy in the realm of high-performance computing. The architecture and design principles laid down by the Sun 880 continue to influence modern computing technologies today.
