LSI22801 SCSI Host Adapter BENEFITS • Increased peripheral connectivity - up to 30 devices • Complete host adapter solution for quick time-to-market • True multi-function device provides better performance than PCI-to-PCI bridge solutions • Up to 80 MBps combined synchronous transfer rate for two 16-bit Ultra SCSI channels • Improved reliability with a single chip solution • Automatic termination determined by cabling environment (ease of use for OEMs and end users) • Complete software support with BIOS and drivers • Termination power supplied through self-resetting current limiting device • Allows custom driver development with SCSI SCRIPTS™ • Connectors for off-board SCSI active LEDs • Any drive in a disk array can be used as the boot device • On-board BIOS supports disk drives with greater than 8-Gbyte capacity The LSI22801 is a PCI-dual channel multi-function, single-ended Ultra SCSI solution. OVERVIEW The LSI22801 host adapter is a multi-function board providing two independent single-ended Ultra SCSI channels. Both SCSI channels are identical, offering increased connectivity without utilizing additional PCI slots. A single board provides a powerful dual channel, multitasking interface for Ultra SCSI peripherals such as disk, tape, CD-ROM, and other SCSI devices. The LSI22801 leverages the LSI53C876 PCI dual channel SCSI multifunction controller capable of connecting directly to the PCI bus, presenting one electrical load, while functioning as a single 32-bit PCI DMA bus master. The LSI22801 includes an on-board configuration utility allowing viewing and changing of default configuration settings for the host adapter and connected SCSI peripherals. The device also provides advanced features for ease of use by modifying the on-board terminators depending on cable configuration and LEDs to help with termination power (TERMPWR) monitoring. The LSI22801 has advanced features which makes it the right choice for applications requiring up to 30 connected peripherals, or for isolating peripheral classes (e.g. CD-ROMs and tape drives on one channel and high performance disk drives on the other). LSI22801 SCSI Host Adapter PCI FEATURES TECHNICAL DESCRIPTION • True multi-function device (per PCI 2.1 Specification) – uses only one PCI slot The LSI22801 uses the LSI53C876 PCI dual channel SCSI multi-function controller. This single-chip multi-function device connects directly to the PCI bus. • Functions as one 32-bit PCI DMA bus master • Two independent DMA channels with internal programmable arbitration TERMINATION CONTROL For each channel the adapter will automatically determine when cables are attached to which connector and properly enable or disable the SCSI terminators. The Table 1 below shows which cable combinations are allowed. 8-bit Internal √ • Supports PCI write and invalidate, read line, and read multiple commands 8-bit External 16-bit External √ • 33 MHz PCI bus zero wait state operation • Maximum burst transfer rate of 132 MBps 16-bit Internal √ √ √ √ √ √ √ √ √ √ √ Table 1. Cable combinations - legal cable combinations allowed by the LSI22801 utilizing the two internal and two external SCSI connectors • Universal 3.3V and 5V PCI Four jumpers included to manually force the different cable configurations. SCSI FEATURES TERMINATION POWER • 16-bit Ultra SCSI design based on the popular LSI53C875 for maximum performance One LED per channel is included to indicate the status of termination power (TERMPWR). • Local memory bus for FLASH memory BIOS storage • SCSI TolerANT™ active negation SCSI driver and receiver technology • SCAM (SCSI Configured AutoMatically) Level 1 functionality for SCSI plug-and-play support • External VHDCI SCSI connector per channel 2 CONFIGURATION UTILITY The resident menu-driven BIOS configuration utility allows the viewing and changing of the default settings for the host adapter and SCSI devices. The following table lists the configuration settings which can be changed. The global settings affect the host adapter and all SCSI devices connected to it. The host adapter boot order can be changed if more than one SCSI host adapter solution is implemented, see Table 2. INTERRUPTS The host adapter includes a jumper to select separate interrupts (channel A routed to INTA# pin and channel B routed to INTB# pin) or shared interrupts (channel A and channel B routed to INTA#/ pin). SUBSYSTEM ID SOFTWARE FEATURES Subsystem ID and Subsystem Vendor ID support enables users to develop custom software while still using a standard board configuration. • Support for DOS, Windows 95, Novell NetWare, Windows NT, UnixWare, and SCO Open Server, OS/2, ASPI Setting Default Global/Device SCAM support Parity checking Host adapter SCSI ID On Enabled Global Global 7 Global Scan order Synchronous transfer rate Data width Disconnect I/O time-out (secs) Scan for device at boot Scan for SCSI LUNs Queue tags Low to high (0 - max) 40 MB (Ultra) 16 On 10 • Software drivers and SCRIPTS compatible with LSI53C825A and LSI53C875 Global • Tagged command queuing for peak performance in multitasking environments Device Device Device Device Yes Device Yes Enabled Device Device • Shared interrupts and shared memory allow multiple PCI devices in a single-interrupt system Table 2.
