Symbios SYM8951U - PCI-to-Ultra2 SCSI Host Adapter Simple Type: SCSI Adapter
At up to 80 MBytes/sec, the SYM8951U host adapter combines the highest Ultra2 SCSI data transfer rates with the high performance PCI system bus. Based on Symbios’ industry first SYM53C895 Ultra2 SCSI I/O Processor, the SYM8951U provides Universal Low Voltage Differential (LVD) signaling for SCSI. LVDlinkTM technology, Symbios’ implementation of LVD transceivers, eliminates the distance and device constraints that exist in today’s Ultra SCSI single-ended designs while offering higher data transfer rates. Installing and configuring the SYM8951U host adapter could not be easier. With built-in SCAM (SCSI Configured AutoMatically) and SCSI bus configuration utilities, setting up the SCSI bus is a snap. Symbios’ powerful SCSI Device Management System (SDMS) software, and on-board BIOS and configuration utility, makes installation of the SCSI I/O subsystem easy and nearly automatic. And with no jumpers, switches, IRQs, system DMA or addresses to budget, installing the SYM8951U 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 either 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 SYM8951U provides twice the performance and allows four times the cable length and number of connected devices. The high SCSI bus bandwidth of Ultra2 SCSI, and the improvements in distance, connectivity, and reliability, make the SYM8951U an ideal host connection to a RAID controller and other demanding I/O applications in the high performance workstation and server markets. The SYM8951U LVDlink transceivers provide the data reliability of differential signaling without the cost of high voltage differential transceivers. For critical data handling applications, Symbios offers data and product reliability, software and hardware compatibility, with easy instability. Symbios and our technology partners’ 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.
