LSI8951U SCSI Host Adapter KEY APPLICATIONS * Intersystem connections - server and workstation to RAID and network management The LSI8951U PCI-to-Ultra2 SCSI host adapter combines Ultra SCSI data transfer rates with reliable data integrity. * Upgrading existing Fast or Ultra SCSI systems OVERVIEW * Adding Ultra2 SCSI hard drives to servers, workstations and RAID storage subsystems Bus Interface: 3/5V PCI PCI Mode: Bus Master Plug-and-Play: Yes SCSI Rate: 40 MBps synchronous (SE) 80 Mbps synchronous (LVD) 14 MBps asynchronous SCSI Bus: 16-bit SE and LVD Bootable: Yes No. of SCSI Devices: 15 SCSI Connectors: Internal: 68-pin HD External: 68-pin VHDCI At up to 80 MBps, the LSI8951U host adapter combines the highest Ultra2 SCSI data transfer rates with the high performance PCI system bus. Based on an industry first, the LSI53C895 Ultra2 SCSI I/O processor, the LSI8951U provides Universal Low Voltage Differential (LVD) signaling for SCSI. LVDlinkTM technology, the implementation of LVD transceivers, eliminates the distance and device constraints that exist in today's Ultra SCSI singleended designs while offering higher data transfer rates. Installing and configuring the LSI8951U host adapter couldn't be easier. With built-in SCAM (SCSI Configured AutoMatically) and SCSI bus configuration utilities, setting up the SCSI bus is a snap. The powerful SCSI Device Management System (SDMS) software, and on-board BIOS and configuration utility make installation of the SCSI I/O subsystem easy and virtually automatic. And with no jumpers, switches, IRQs, system DMA or addresses to budget, installing the LSI8951U to connect up to 15 Ultra2 devices becomes a matter of plugging in the host adapter and loading the drivers. Whether you are migrating from Ultra SCSI or Fast SCSI, Ultra2 SCSI provides a high performance I/O migration path while preserving your existing PCI-SCSI software investment. As compared to Ultra SCSI designs, the LSI8951U provides twice the performance and allows four times the cable length and number of connected devices. The high SCSI bus bandwidth of Ultra2 SCSI, along with improvements in distance, connectivity, and reliability make the LSI8951U an ideal host connection to a RAID controller. It is also suitable for other demanding I/O applications in the high performance workstation and server markets. The LSI8951U LVDlink transceivers provide the data reliability of differential signaling without the cost of high-voltage differential transceivers. For critical data handling applications, LSI Logic offers data and product reliability, software and hardware compatibility, with easy installability. Extensive host adapter and software testing ensures OEM compatibility with all major operating systems and a wide variety of SCSI-1, Fast SCSI-2, Ultra SCSI and Ultra2 SCSI devices.

HOST ADAPTER COMPATIBILITY AND QUALITY LSI Logic is a key developer and contributor to the original committees that defined today's SCSI and PCI standards. Our continuing work with other industry leaders of core chip sets, processors, system providers, SCSI device peripherals, BIOS, and operating systems enables us to provide users with the utmost compatibility and interoperability. Product compatibility and interoperability are rigorously tested and our ISO-9001 certified fabrication facilities assures users of the highest levels of product quality and reliability. LV D L I N K - U N I V E R S A L LV D T R A N S C E I V E R S Balancing backward compatibility with I/O performance and lower costs, the LSI53C895 integrates our universal LVDlink transceivers with the Ultra2 SCSI I/O processor. Depending on SCSI bus connections, bus cabling conditions are sensed and the universal LVDlink transceivers automatically select singleended or LVD SCSI modes and indicate the mode with the on-board SE or LVD LEDs. In single-ended mode, the LSI8951U performs synchronous data transfers up to Ultra SCSI rates, subject to standard Ultra SCSI cable distance and connected device constraints. In LVD mode, the host adapter supports up to 12.5-meter cables and up to 15 LVD devices with the same cables and connectors as defined in the SCSI-3 Parallel Interface ANSI standard. LVDlink transceivers also provide fail-safe operation of the receiver by detecting when the LSI8951U is connected to a high voltage differential (HVD) signal. When connected to HVD, the LSI8951U's SCSI bus enters a high-impedance mode and activates the on-board HVD LED.
