Product Description
The HP LSI21040 is a powerful dual-channel Ultra-160 SCSI controller card, designed to provide robust and high-speed connectivity for a wide range of SCSI peripherals. This controller supports both Low Voltage Differential (LVD) and Single-Ended (SE) modes, offering flexibility in connecting various types of SCSI devices, from modern LVD drives to older SE configurations. The Ultra-160 standard signifies a maximum transfer rate of 160 MB/s per channel, ensuring efficient data throughput for demanding storage applications. Featuring dual channels, the LSI21040 allows for the connection of a significant number of SCSI devices, typically up to 15 devices per channel (totaling 30 devices), depending on the cabling and termination. This makes it suitable for servers requiring extensive internal or external storage expansion, including multiple hard drives, tape drives, or optical drives. The card utilizes a standard PCI bus interface, ensuring compatibility with a broad range of older server and workstation motherboards. This controller card is a critical component for systems that rely on SCSI technology for storage connectivity. Its dual-channel architecture and support for both LVD and SE modes provide a versatile solution for managing and accessing SCSI devices. The HP LSI21040 is engineered for reliability and performance, making it a dependable choice for enterprise environments that require robust SCSI I/O capabilities.
