2.Configure termination.

If you are installing the drive in a system that has other SCSI devices installed, terminate only the end devices on the SCSI bus.

Figure 4 shows the three most common termination configu- rations. LW model drives do not have internal terminators or any other way of adding internal termination on the drive. You must provide external termination to these drives when termination is required. This is normally done by adding an in-line terminator on the cable. See Figure 9 on page 27 for an illustration showing a system configuration that uses an inline terminator.

• Use active (ANSI SCSI-2 Alternative 2) single- ended terminators when terminating a bus oper- ating in single-ended mode.

•Use SPI-2-compliant active low voltage differential termina- tors when terminating a SCSI Ultra2 bus operating in LVD mode.

•Some controllers prefer to remain terminated even if they are in the middle of the chain. Also, some controllers treat the internal and external chains as separate logical buses. This means you may need to terminate both the first and last devices on both logical buses to achieve proper termi- nation. If necessary, refer to your system or controller doc- umentation to see how this is handled in your particular system.

ST136403LW/LC specifications

The Seagate ST136403LW/LC is a vintage hard disk drive that belongs to Seagate's esteemed lineup of storage solutions. Known for its reliability and performance during the era of its release, this model caters to various computing needs, particularly in enterprise and industrial settings.

One of the standout features of the ST136403LW/LC is its capacity of 36.4 GB, which, although modest by modern standards, was quite impressive in the early 1990s. This size made it ideal for businesses at the time looking to store substantial amounts of data without the high costs associated with larger enterprise solutions.

The drive operates at a speed of 7200 RPM, allowing for efficient data access and transfer. The spindle speed is crucial for performance, and 7200 RPM was considered rapid for hard drives in that period. This enhanced speed translates to quicker read and write times, making it suitable for applications that require timely data retrieval.

The ST136403LW/LC utilizes the SCSI interface, a popular choice in server environments for its robustness and speed. SCSI technology facilitates the connection of multiple drives, providing the ability to network various devices and manage them effectively. The multi-device capability is particularly beneficial for enterprise applications, ensuring that data centers can efficiently manage resources.

In terms of physical characteristics, the ST136403LW/LC is a 3.5-inch form factor drive, a standard size that fits into most desktops and servers of its generation. This compatibility is vital for users looking to upgrade their existing systems without the need for significant modifications.

The drive also includes built-in error correction features, enhancing data integrity and reliability, crucial for business operations where data loss can lead to substantial repercussions. Additionally, it employs a sealed enclosure design, providing protection against dust and moisture, thereby extending the drive's lifespan in demanding environments.

Furthermore, Seagate's reputation for durability is echoed in the ST136403LW/LC, as it was designed to endure the rigors of everyday use, particularly in enterprise settings where uptime is critical.

In conclusion, the Seagate ST136403LW/LC serves as an essential piece of technology from its era, characterized by its 36.4 GB capacity, 7200 RPM speed, SCSI interface, and robust construction. While modern storage solutions have far surpassed its capabilities, this drive remains a testament to Seagate's legacy in the storage industry, reflecting the innovations of its time.
