Product Description
The Adaptec AHA-2940U2B is a high-performance PCI controller card designed for Ultra2 SCSI connectivity. It supports both Low Voltage Differential (LVD) and Single-Ended (SE) modes, offering flexibility in connecting a wide range of SCSI devices. In LVD mode, the card can achieve data transfer rates of up to 40 megabytes per second, significantly faster than previous SCSI generations, while SE mode provides backward compatibility with older SCSI devices. The controller features a 68-pin connector, which is standard for Ultra2 SCSI devices, and allows for the connection of multiple devices in a daisy-chain. The PCI interface ensures efficient data transfer between the host system and the connected SCSI peripherals. This card is ideal for workstations and servers that require robust and high-speed storage solutions, such as those used in multimedia production, scientific research, or enterprise environments. Adaptec's reputation for reliability is reflected in the AHA-2940U2B. It provides stable performance and broad compatibility with various SCSI devices and operating systems. The dual-mode capability (LVD/SE) makes it a versatile choice for upgrading existing SCSI systems or building new ones that demand advanced storage performance and expandability.
