Description
The Compaq 401922-001 is a PCI adapter card designed to provide a Single Channel Ultra SCSI interface for computer systems. Ultra SCSI, also known as Fast-20 or SCSI-3, offers a significant improvement in data transfer speeds over earlier SCSI standards, reaching up to 20 Megabytes per second (MB/s). This makes it suitable for connecting high-performance storage devices such as hard drives and tape drives where speed and reliability are critical. The card utilizes a differential signaling method for its SCSI connection. Differential SCSI offers better noise immunity and allows for longer cable lengths compared to single-ended SCSI, which is advantageous in server environments or systems where devices might be located at a distance from the adapter. The card typically features a specific connector type, such as a 68-pin VHDCI (Very High Density Interconnect Cable) connector, designed for differential SCSI cabling. As a single-channel adapter, it supports a bus that can accommodate up to seven differential SCSI devices. This allows for the connection of multiple storage devices, such as hard drives and tape backup units, to a single PCI slot. The card plugs into a standard PCI slot on the computer's motherboard, providing a robust and high-speed interface for legacy SCSI peripherals in server or workstation configurations.
