Product Description
The Dell 1686906-19, identified by Dell part number 004Cvf, is a PCI SCSI controller card built around the highly regarded Adaptec AHA-2940U2W chipset. This card enables Ultra2 LVD (Low Voltage Differential) SCSI connectivity, a standard known for its improved signal integrity and higher transfer speeds compared to earlier SCSI versions. It offers a significant performance boost for connecting SCSI hard drives, tape drives, and other peripherals in server and workstation environments. Featuring a dual-channel design, the controller provides both an internal 50-pin connector and an external 68-pin VHDCI connector. This dual connectivity allows for the management of up to 15 SCSI devices on each channel, totaling 30 devices. The Ultra2 LVD interface supports data transfer rates of up to 80 MB/s per channel, making it suitable for demanding storage applications that require fast and reliable data access. The LVD technology also offers better noise immunity and longer cable lengths compared to single-ended SCSI. This controller card is designed for easy integration into systems equipped with a 32-bit PCI slot. It is commonly found in Dell PowerEdge servers and other enterprise-grade machines that require robust and scalable storage solutions. The Adaptec AHA-2940U2W chipset is known for its stability and broad compatibility with various operating systems, including Windows Server, Linux, and other Unix-based systems, often requiring specific drivers for full functionality. The Dell 1686906-19 represents a reliable option for expanding storage capacity and performance using SCSI technology.
