Adapter Installation

This chapter describes how to install the adapter in your system and verify that it has been installed correctly.

IB-HCA Bus and Slot Selection

For optimal performance, the IB-HCA card should be installed in the fastest available bus, preferably a 133 MHz PCI-X bus. But the IB-HCA can operate on the slower PCI-X and PCI buses. The IB-HCA should also be installed on its own PCI leaf. Plugging the IB-HCA card into a PCI leaf shared by another (slower) device can result in lower performance.

Installing the Adapter

Caution – Electronic components on printed circuit boards are extremely sensitive to static electricity. Ordinary amounts of static electricity generated by your clothing or work environment can damage the electronic equipment. When installing the IB- HCA in a system, use anti-static grounding straps and antistatic mats to help prevent damage due to electrostatic discharge.

Note – Refer to your system installation or service manual for detailed instructions for the following steps.

1.Power off your server, using the standard shut down procedures described in the Solaris Handbook for Sun Peripherals or your system service manual.

The Solaris Handbook for Sun Peripherals is shipped with the Solaris Operating System software and is available on the http://docs.sun.com web site.

PCI specifications

Sun Microsystems, a pioneer in the development of computer systems and software, played a significant role in the advancement of PCI (Peripheral Component Interconnect) technology. Introduced in the early 1990s, PCI was a revolutionary standard for connecting peripheral devices to a computer's motherboard, and Sun Microsystems implemented this technology across many of their systems.

One of the primary features of Sun's PCI implementation was its ability to support a wide range of peripheral devices. This versatility allowed users to expand their systems with various components, such as graphics cards, networking interfaces, and storage controllers, which improved system performance and functionality. The PCI standard enabled multiple devices to communicate concurrently, enhancing overall operational efficiency.

Another characteristic of Sun's PCI systems was their high bandwidth capability. Sun Microsystems designed their workstations and servers with a focus on delivering superior data transfer rates, which was essential for high-performance applications such as computer-aided design and scientific simulations. The PCI standard supported different bandwidth configurations, allowing Sun to optimize their hardware for demanding tasks.

Sun systems supported various PCI versions, including PCI 2.1 and PCI-X, which further increased data transfer rates and provided backward compatibility with older PCI devices. The transition to PCI Express (PCIe) marked another leap in performance, and Sun embraced this technology by incorporating it into their hardware, providing users with enhanced speed and improved energy efficiency.

In addition to supporting high-performance peripherals, Sun Microsystems placed a strong emphasis on reliability and fault tolerance in their PCI designs. Many of their servers included features like redundant power supplies and advanced cooling systems to ensure long-term operation and minimize downtime.

Security was also a consideration in Sun's PCI implementation. The company developed advanced features to protect data integrity and prevent unauthorized access, making their systems suitable for enterprise-level applications.

Overall, Sun Microsystems' approach to PCI technology was characterized by flexibility, performance, reliability, and security. Their commitment to innovation helped to establish PCI as a crucial standard in the industry, contributing to the evolution of computer systems and enhancing the user experience for a variety of applications. Sun's legacy in PCI technology continues to influence modern computing as businesses continue to seek efficient and high-performing solutions for their computing needs.
