IBM Adaptec AHA-2940U W B SCSI Controller FRU: 10L7095

The Adaptec PCI Fast/Wide Ultra SCSI Adapter permits the attachment of high-speed Ultra SCSI devices to network server computer systems and commercial desktop computers. With data transfer speeds as high as 40 Mb/s and the adoption of innovations such as Disconnect/Reconnect, the PCI Fast/Wide Ultra SCSI Adapter will accommodate fast storage devices with ease. This high data transfer rate is further enhanced by the use of Busmastering Direct Memory Access (DMA) that allows the adapter to control the transfer of data from the peripherals to the system memory, relieving the system processor of this time-consuming burden.
