4.Installation of internal SCSI cables

The INI-9100U has one 50-pin internal SCSI bus connector and the INI-9100UW has two internal connectors: one 50-pin flat ribbon SCSI connector, and one 68-pin high density ultra wide SCSI connector; both internal connectors may be used in tandem or singularly, depending on your bus configuration. Installation of internal SCSI cables must be performed before replacing the system covers. The internal ribbon cable is made with multiple connectors attached and used to daisy chain the host adapter with two or more devices. It is important that the cable installed correctly for proper operation. The cable has a colored stripe running the length of the cable, on the edge distinguishing the pin one side of the connector. These identifying markings must match when mated on the host adapter board.

When attaching ultra wide SCSI internal devices, use the 68-pin high density wide SCSI internal cable connector. This connector, identified by J4 on the host adapter (refer to figure 3-2), is keyed for proper orientation and connection. Insert on end of the internal wide ultra SCSI cable into the INI-9100UW host adapter and the other connectors in a similar fashion into your ultra wide SCSI connectors as described in the appropriate manufacturers instructions.

When attaching ultra SCSI devices, use the 50-pin ultra SCSI cable connector, identified by J1 on the host adapter (refer to figure 3-4). This connector has a triangle marking that identifies pin-one. Align the internal cable into the host adapter and the other cable connectors

INI-9100UW, INI-9100U specifications

The Initio INI-9100UW and INI-9100U are high-performance SCSI (Small Computer System Interface) controllers designed to provide exceptional data transfer rates and efficient connectivity for various storage solutions. These controllers are particularly favored in environments that demand reliable and fast data access, including servers and workstations.

One of the standout features of the INI-9100 series is its ability to support ultra-wide SCSI, allowing for data transfer rates of up to 40 MB/s. This speed is crucial for applications requiring rapid data movement, such as databases, streaming applications, and intensive computing tasks. The INI-9100UW variant extends this capability with its support for 68-pin connectors, which further enhances data throughput by allowing for a greater number of devices to be connected simultaneously.

Both the INI-9100UW and INI-9100U are built on a robust architecture, which includes integrated support for a wide range of SCSI devices. This includes hard disk drives, CD-ROMs, and tape drives, making these controllers versatile solutions for both modern and legacy systems. Their compatibility with various operating systems, including Windows and Linux, ensures seamless integration into existing setups.

Furthermore, the Initio controllers employ advanced technologies such as asynchronous transfers and cycle stealing, which minimize CPU load and allow the system to handle multiple tasks simultaneously without bottlenecks. This makes them particularly advantageous in multitasking environments.

Another key characteristic of the INI-9100 series is their dedicated onboard BIOS, which simplifies device management and setup processes. Users can easily configure the controllers for optimal performance using the user-friendly interface provided by the BIOS.

In summary, the Initio INI-9100UW and INI-9100U are powerful SCSI controllers that offer high-speed data transfer capabilities, robust architecture, and versatile compatibility with various SCSI devices. Their advanced technologies and user-friendly features make them ideal solutions for environments requiring reliable and efficient data access. As data storage needs continue to evolve, the INI-9100 series remains a valuable asset for both enterprise-level and individual users seeking to enhance their storage solutions.
