LSI22801 SCSI Host Adapter BENEFITS • Increased peripheral connectivity - up to 30 devices • Complete host adapter solution for quick time-to-market The LSI22801 is a PCI-dual channel multi-function, single-ended Ultra • True multi-function device SCSI solution. provides better performance than PCI-to-PCI bridge solutions OVERVIEW • Up to 80 MBps combined The LSI22801 host adapter is a multi-function board providing two synchronous transfer rate for independent single-ended Ultra SCSI channels. Both SCSI channels are two 16-bit Ultra SCSI channels identical, offering increased connectivity without utilizing additional PCI slots. A single board provides a powerful dual channel, multitasking interface • Improved reliability with a single chip solution for Ultra SCSI peripherals such as disk, tape, CD-ROM, and other SCSI devices. • Automatic termination determined The LSI22801 leverages the LSI53C876 PCI dual channel SCSI multi- by cabling environment (ease of function controller capable of connecting directly to the PCI bus, presenting use for OEMs and end users) one electrical load, while functioning as a single 32-bit PCI DMA bus master. • Complete software support The LSI22801 includes an on-board configuration utility allowing with BIOS and drivers viewing and changing of default configuration settings for the host adapter • Termination power supplied and connected SCSI peripherals. through self-resetting current limiting device The device also provides advanced features for ease of use by modifying the on-board terminators depending on cable configuration and LEDs to • Allows custom driver development ™ help with termination power (TERMPWR) monitoring. with SCSI SCRIPTS The LSI22801 has advanced features which makes it the right choice for • Connectors for off-board SCSI active LEDs applications requiring up to 30 connected peripherals, or for isolating peripheral classes (e.g. CD-ROMs and tape drives on one channel and high • Any drive in a disk array can performance disk drives on the other). be used as the boot device • On-board BIOS supports disk drives with greater than 8-Gbyte capacity LSI22801 SCSI Host Adapter PCI FEATURES TECHNICAL DESCRIPTION • True multi-function device The LSI22801 uses the LSI53C876 PCI dual channel SCSI multi-function (per PCI 2.1 Specification) controller. This single-chip multi-function device connects directly to the PCI bus. – uses only one PCI slot TERMINATION CONTROL • Functions as one 32-bit PCI For each channel the adapter will automatically determine when cables DMA bus master are attached to which connector and properly enable or disable the SCSI terminators.
