SCSI Cabling

You can daisy chain up to 15 devices on the SunSwift SBus Adapter as follows:

Wide-to-wide devices

Use a 68-pin to 68-pin cable.

 

Always put wide SCSI devices closest to the host system.

Wide-to-narrow devices

Use a 68-pin to 50-pin cable.

 

You can include only one wide-to-narrow cable along a

 

chain of peripherals.

 

Always put the narrow SCSI devices at the end of the

 

chain.

The SCSI bus must be terminated at the end of the chain.

Single byte data transfers from an odd memory address to a SCSI device are not supported by the SunSwift SBus Adapter SCSI-2 (fas) device. Refer to SMCC Open Issues Supplement Solaris 2.5 Hardware: 1/96 for more detailed information.

If you use the SunSwift SBus Adapter for SCSI purposes only, you must change the device name from SUNW,hme to SUNW,hme_idle to avoid a “Link Down — cable problem?” message. Refer to SMCC Open Issues Supplement Solaris 2.5 for more detailed information.

Ethernet Cabling

An additional Ethernet cable is required if you want to use your system’s existing Ethernet interface and the SunSwift SBus Adapter Ethernet interface.

Disabling Your Current Ethernet Device

If you remove your system’s existing Ethernet cable (either from its on-board Ethernet device or from an existing Ethernet card) and insert it into the SunSwift SBus Adapter Ethernet connection, you must disable your current card’s Ethernet device. For example, if your current Ethernet device is called le0, you would remove its IP address and hostname from the /etc/hosts file and remove the /etc/hostname.le0 file itself.

SunSwiftTM specifications

Sun Microsystems introduced the SunSwiftTM, a series of advanced networking interfaces and I/O technology designed to enhance the performance of their workstations and servers. SunSwift interfaces were built to address the increasing demand for high-speed data transfer and connectivity in enterprise environments. The architecture was characterized by a focus on achieving higher bandwidth, lower latency, and improved reliability.

One of the main features of SunSwift is its ability to support high-speed data communication through various Ethernet and token ring implementations. The SunSwift cards were designed to be compatible with multiple Sun systems, ensuring wide applicability across different server models. This compatibility allowed users to upgrade their network interfaces without needing to invest in new hardware, promoting cost efficiency and flexibility in network design.

Incorporating the latest advancements in technology, SunSwift leveraged technologies such as PCI (Peripheral Component Interconnect) to enhance data throughput capabilities. The use of PCI enabled the SunSwift to keep pace with the evolving standards of computing, allowing it to handle the demands of modern applications and workloads.

Another key characteristic of SunSwift is its support for network protocols essential for enterprise functionality, including TCP/IP, which provided a robust framework for network communication. The interface achieved high-performance levels while maintaining compatibility with various operating systems, thereby simplifying network management and deployment.

The reliability of SunSwift was further evidenced through advanced error detection and correction mechanisms. This focus on quality ensured that data integrity was preserved, reducing the chances of packet loss during transmission. Additionally, Sun Microsystems incorporated features that facilitated ease of use, such as simple installation processes that required minimal configuration, making SunSwift accessible even to users with limited technical expertise.

Overall, SunSwift represented a significant advancement in network interface technology during its era, showcasing Sun Microsystems' commitment to delivering high-performance solutions that cater to the demands of enterprise networking. Its blend of speed, reliability, and compatibility made it a valuable asset for organizations seeking to enhance their networking infrastructure and support their growing data communication needs. With its innovative features and robust technology, SunSwift played a crucial role in the evolution of networking capabilities within the Sun Microsystems product lineup.
