The hme device driver handles the SUNW,hme device on these hardware devices:

SunSwift SBus Adapter

SunFastEthernet Adapter 2.0

Sun Ultra 1 Creator Series systems

Sun Ultra 2 Series system

Ultra Enterprise 3000, 4000, 5000, and 6000 systems

This chapter gives a hardware overview of the SUNW,hme device, provides information on the operating speeds and modes for the SUNW,hme device, and discusses auto-negotiation, the internal transceiver, and the external transceiver for the hme device driver. Note that the external transceiver is not present on the SunSwift SBus Adapter.

Hardware Overview

The SUNW,hme device provides 10BASE-TX or 100BASE-T networking interfaces using the Fast Ethernet Parallel Port SCSI (FEPS) ASIC and an internal transceiver. The driver automatically sets the link speed to 10 or 100 Mbps and conforms to the 100BASE-T IEEE 802.3u Ethernet standard. The FEPS ASIC provides the SBus interface and Media Access Control (MAC) functions. The internal transceiver, which connects to an RJ-45 connector on all of the above hardware devices, provides the physical layer functions.

Sun Microsystems, established in 1982, became a pioneering force in the realms of computing and technology. Initially founded by four Stanford University graduates, the company was built on innovative ideas and a vision to create powerful computing solutions. One of the standout features of Sun Microsystems was its commitment to open systems and network computing. Sun's early adoption of Unix operating systems significantly influenced the development of reliable and scalable systems.

One of the key technologies developed by Sun was the SPARC architecture. This scalable, high-performance RISC (Reduced Instruction Set Computer) architecture powered many of its servers and workstations, allowing for enhanced computing capabilities. SPARC systems were well-regarded for their performance efficiency and reliability, making them a popular choice for enterprise applications.

Sun also played a crucial role in software development. The introduction of the Java programming language in the mid-1990s revolutionized how developers approached cross-platform application development. With its tagline “Write Once, Run Anywhere,” Java enabled applications to run on various platforms without modification. This technology became foundational in web-based applications and enterprise solutions.

Another notable aspect of Sun Microsystems was its commitment to networking and storage solutions. The company developed robust server systems that catered to high-performance computing demands, supporting enterprises in managing vast amounts of data. Sun’s Network File System (NFS) allowed seamless file sharing across networks, which became a standard in many organizations.

The company was also a pioneer in providing various services and solutions for data centers, including virtualization and cloud computing approaches that preceded the wave of cloud services we see today. Their emphasis on innovative storage solutions and data management systems positioned them as industry leaders.

Though Sun Microsystems was acquired by Oracle Corporation in 2010, its technological legacy continues to shape the IT landscape. The contributions made by Sun in areas such as software development, hardware architecture, and open systems have left an indelible mark on the technology industry. The emphasis on openness and innovation laid the groundwork for many principles that guide modern computing, making Sun Microsystems an integral part of the history of technology.
