With LVD, you can use cables up to 12 meters long. Throughput on each SCSI channel can be as high as 320 Mbps. PCI is an I/O architectures. It is designed to increase data transfers without slowing down the central processing unit (CPU). You can install the Intel® SRCU41L Raid Controller storage adapter in PCI computer systems with a standard bracket type. With these adapters in your system, you can connect SCSI devices over a SCSI bus. Note: For Ultra320 SCSI performance, you must connect only LVD devices to the bus. Do not mix SE with LVD devices, or the bus speed will be limited to the slower SE (Ultra SCSI) SCSI data transfer rates. Do not connect a high voltage differential (HVD) device to the controller. 1.1.1 Operating System Support The Intel® Raid Controller SRCU41L supports major operating systems, such as Windows (2000, Server 2003, and XP), Red Hat* Linux, SuSe Linux, Novell* NetWare, SCO* OpenServer, and UnixWare*. Other software support ensures data integrity by intelligently testing the network before completing negotiation. 2 Intel® Raid Controller SRCU41L User Manual
