LSI21002 SCSI Host Adapter KEY APPLICATIONS • Workstations, high-end desktops and servers that require high I/O performance and legacy peripheral support • Ideal for desktop configurations that require high performance data I/O while simultaneously supporting existing peripherals (CDs, scanners) • Supporting mixed single-ended and LVD SCSI devices system applications BENEFITS • Increased performance with support of existing systems • Complete host adapter solution for quicker OEM time-to-market • True multi-function, singlechip device provides better performance than discrete PCIto-PCI bridge solutions or singlechannel devices supporting dual SCSI interfaces • Improved reliability with singlechip solution • Complete software support with BIOS and drivers for all major operating systems • Features LSI Logic’s LVDlink universal LVD technology The LSI21002 PCI-to-Ultra2 SCSI dual channel host adapter supports a wide variety of Fast and Ultra SCSI devices. OVERVIEW The LSI21002 dual channel PCI-to-Ultra2 SCSI host adapter board by LSI Logic is designed for systems using high performance disks as well as supporting a wide variety of Fast and Ultra SCSI devices. By using the LSI53C896 dual channel PCI-to-Ultra2 SCSI controller chip to directly interface to the PCI and SCSI buses, the LSI21002 is able to provide the high reliability and cost effectiveness of a single-chip design. By having two complete and separate SCSI channels, the LSI21002 can dedicate one channel, with full connectivity, to high performance devices and the other channel, also with full connectivity, to legacy SCSI devices. Matching the performance of the 32-bit PCI bus to two independent SCSI channels, the LSI21002 host adapter provides up to 120 MBps aggregate SCSI throughput. With LSI Logic’s LVDlink™ (Low Voltage Differential) and TolerANT™ technology, the LSI21002 provides unmatched performance, device connectivity and signal reliability. LVDlink is LSI Logic’s implementation of the Universal Low Voltage Differential standard. At last, one board provides a powerful dual channel, scalable, multi-tasking interface for high performance SCSI disk drives, CD-Rs, CD-RWs, scanners, interconnect, and other single-ended or LVD SCSI devices. The dual channels increase to connectivity to up to 30 devices without utilizing an additional PCI slot or PCI load. Designing systems with the LSI21002 is easy with one channel dedicated to high performance LVD devices and the second dedicated to supporting single-ended legacy devices. Or both channels can be used to support singleended devices. LSI21002 SCSI Host Adapter BENEFITS (Continued) • Ultra2 SCSI provides increased connectivity (cable length and number of SCSI devices supported) over Ultra SCSI • Automatic termination determined by cabling environment provides improved ease-of-use for the OEM and the end user • Termination power supplied through self-resetting current limiting device • Any drive in a disk array can be used as the boot device • On-board BIOS supports greater than 8 GB disk drives SCSI FEATURES • SCSI buses feature two true, independent SCSI buses: – Channel A - Legacy Fast/Ultra SCSI 8- and/or 16-bit bus Single-ended mode (only) Supports Fast/Ultra SCSI bus speeds of up to 20 or 40 MBps with mixed Fast/Ultra SCSI peripherals on the bus Supports 8- and/or 16-bit peripherals simultaneously Supports up to 7 8-bit devices and/or 15 16-bit devices Connectors Internal: 50-pin LD, 68-pin HD External: 50-pin latching, HD 2 The LSI21002 is a zero wait-state DMA bus master in 32-bit PCI bus systems and supports PCI 64-bit Dual Address Cycles for greater system memory addressability. Built to the PCI Universal board standards, the LSI21002 works in 3.3 or 5 V PCI bus systems. The LSI21002 includes an on-board configuration utility, allowing the viewing and changing of default configuration settings for the host adapter and attached SCSI devices. It also provides advanced ease-of-use features such as automatic termination (depending on cable configuration) on the single-ended channel. The advanced features of the LSI21002 32-bit host adapter make it the right choice for high-performance desktops, workstations and servers. SCSI DEVICE MANAGEMENT SOFTWARE (SDMS) SDMS Software Features • Multiple host adapter support • Scatter/gather • Tagged command queuing for peak performance in multi-tasking environments • Shared interrupts and shared memory to allow multiple PCI devices in a single-interrupt system • Multiple LUNs per SCSI ID for RAID and media changer capability • ASPI interface support • Multi-initiator in most operating systems • Disconnect/reselect support • Target initiated negotiation • On-board, field upgradeable BIOS in Flash ROM • On-board serial EEPROM for SCSI bus configuration storage SDMS Software Support Operating systems supported are: DOS (with ASPI support), Windows 3.1, Windows for Workgroups 3.11, Windows 95, 98, Windows NT 3.51 & 4.0, Novell NetWare 3.2 & 4.1X, SCO UNIX Open Server 5.0.2 and above, UNIXWare 2.1 & 7, OS/2.4X, and Solaris 2.6. Utilities: Install, Flash utility (DOS only), SCSI format, SCSI configuration, verify. SCSI AUTOMATIC TERMINATION The LSI21002 PCI-to-Ultra2 SCSI host adapter automatically determines if cables are attached to Channel A’s (single-ended only) SCSI connectors and then properly enables/disables that channel’s SCSI terminators. Channel B (LVD/SE channel) is always terminated. PCI FEATURES • Direct (bus master) memory access for low overhead with 32-bit burst data transfers at 133 MBps for 32-bit PCI data transfer rates • 33 MHz bus master with zero wait-state PCI transfers • Up to 128 dword PCI burst rate to maximize the PCI data transfer rate • Functions as one, 32-bit PCI DMA bus master • Two independent DMA channels with internal arbitration • Supports PCI write and invalidate, read Line, and read multiple commands • Supports Dual Address Cycles (DAC) for system memory addressability > 4GB • Complies with PCI bus power management specification, version 1.1 INTERRUPTS The host adapter provides separate interrupts for each channel (channel A routed to INTA# pin and channel B routed to INTB# pin). SUBSYSTEM ID The on-board LSI53C896 controller provides PCI configuration registers for Subsystem ID and Subsystem Vendor ID. However, it is possible for OEMs to develop custom software and store different numbers in the on-board serial EEPROM while maintaining a standard board configuration.
