Product Description
The QLogic PC2110401-13 is a host bus adapter (HBA) designed to connect SCSI peripheral devices to a computer system. It specifically supports the Wide Differential SCSI interface, which allows for higher data transfer rates and longer cable lengths compared to standard SCSI. The 68-pin connector is characteristic of Wide SCSI configurations, enabling the connection of multiple devices in a daisy-chain topology. This controller card would typically be installed in a PCI or PCI-X slot within a server or workstation. The 'Wide' aspect refers to the 16-bit data path, doubling the bandwidth of narrow SCSI, while 'Differential' signaling provides improved signal integrity over longer distances and in electrically noisy environments, making it suitable for demanding server applications. The maximum theoretical data transfer rate for Ultra Wide SCSI is 40MB/s. QLogic is a well-known manufacturer of storage networking components, and this card would have been used to connect high-performance storage devices such as hard drives, tape drives, or optical drives in systems where SCSI was the preferred interface. It is designed for reliability and performance in server environments, supporting the connection of numerous SCSI IDs within a single bus.
