The LSI8751D PCI-to-Fast/Ultra Wide Differential SCSI host adapter combines
Ultra SCSI data transfer rates with reliable data integrity.
OVERVIEW
The LSI8751D host adapter combines Ultra SCSI data transfer rates with
the reliable data integrity of High Voltage Differential (HVD) signaling and
the high performance PCI system bus. The LSI8751D supports 16-bit SCSI-1
and -2 (Fast) devices as well as Ultra SCSI devices. As part of the LSI Logic
brand of host adapters built around the LSI53C875 PCI-SCSI controller, the
LSI8751D shares a common BIOS and operating system driver set.
Up to 15 other SCSI devices may be connected internally and/or
externally. The PCI bus provides Plug-and-Play with no jumpers, switches,
IRQs, system DMA or addresses to budget, making installation a matter of
plugging in the host adapter, setting the termination and loading the drivers.
The LSI8751D does not shrink the entire SCSI bus performance to the
slowest device on the bus. Whether you are connecting SCSI, Fast or Ultra
SCSI devices, the LSI8751D matches its transfer rates to the highest rate of
each device on the bus.
For critical data handling applications, LSI Logic offers data and product
reliability, software and hardware compatibility, easy installation, and extensive
host adapter and software testing. Rigorous quality management systems
ensure OEM compatibility with all major operating systems and a wide variety
of SCSI-1, Fast SCSI-2, and Ultra SCSI devices.
Powerful SCSI Device Management System (SDMS) software, on-board
BIOS and configuration utility make SCSI I/O subsystem installation easy
and virtually automatic.

HOST ADAPTER COMPATIBILITY AND QUALITY
SCSI Bus Support
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.
