LSI8955U HOST ADAPTER BOARD The Communications Company TM SINGLE-CHANNEL ULTRA160 SCSI HOST ADAPTER BOARD FOR WORKSTATIONS The LSI8955U is a single-channel Ultra160 SCSI host adapter board built with the LSI53C1000 controller. It supports the Ultra160 initiative with support for double transition clocking, Cyclical Redundancy Check (CRC) and SureLINKTM enhanced domain validation. Domain validation tests link integrity and ensures that the system is adequate for Ultra160 SCSI data transfers, which provide robust system operation. OVERVIEW Figure 1 below shows the major components on the LSI8955U host adapter board. APPLICATIONS * Internet/Intranet, network, video, e-mail, printing, database management, etc. * Workstations, CAD/CAM, industrial simulation, etc. * Host Attach for RAID and JBOD mass storage subsystems -- anywhere data access is the bottleneck PCI INTERFACE * 64-bit, 66 MHz PCI interface, 528 MBps zero wait state transfer rate 68-pin HD * 64-bit addressing (DAC) support * PCI 2.2 compliant 68-pin HD * PCI Power Management 1.1 compliant LSI53C1000 * PC99 compliant * Supports PCI Hot Plug electrical specification LSI8955U 64-bit Universal Connector Figure 1: LSI8955U host adapter board * Vital Product Data Option LSI8955U Host Adapter Board SCSI INTERFACE LSI53C1000 CONTROLLER * One Ultra160 SCSI channel The LSI53C1000 single-channel Ultra160 controller provides the PCI and SCSI functionality for the LSI8955U host adapter board. * Supports Ultra160 MBps SCSI * Double transition clocking for 160 MBps throughput * CRC (Cyclical Redundancy Check) provides complete end-to-end protection of the SCSI I/O * SureLINK domain validation technology * Connectivity * Fast, Ultra, Ultra2, and Ultra160 SCSI data transfer capability * 68-pin HD internal PCI INTERFACE The LSI8955U host adapter board has a 64-bit PCI interface which is backward compatible with 32-bit/66MHz PCI. Dual Address Cycle (DAC) support allows for increased addressability. The LSI8955U host adapter board is PCI 2.2 compliant and provides support for PCI power management, Subsystem Vendor ID, Vital Product Data (VPD), and Extended access cycles (MRL, MRM, MWI). SCSI INTERFACE The LSI8955U supports the Ultra160 SCSI initiative including double transition clocking, CRC (Cyclic Redundancy Check) and domain validation. Double transition clocking refers to transferring data on both polarity edges of the clock signal. It is used in the data phases to perform data transfers on both edges of the REQ or ACK. CRC is a 32-bit error correction scheme to ensure robust error from data transfers at Ultra160 speeds. * 68-pin HD external BOARD CHARACTERISTICS SURELINK DOMAIN VALIDATION TECHNOLOGY * Automatic or manual termination Available exclusively from LSI Logic, SureLINK domain validation is an advanced technology that detects the configuration of the SCSI bus and automatically tests and detects marginal cable environments and adjusts the SCSI transfer rate to ensure system reliability. SureLINK technology exceeds Ultra160 SCSI by providing not only Basic (Level 1) and Enhanced (Level 2) domain validation, but adds Margined (Level 3) domain validation. This enhancement margins LVD drive strength and clock signal timing characteristics to test for and identify marginal Ultra160 systems. * Cable connection sensing option FLASH MEMORY * Universal (SE/LVD) termination on Channel A The LSI8955U board provides up to 128K x 8 flash memory device for storing the SCSI BIOS. A RAID enabled BIOS is available as an upgrade option for those applications requiring RAID functionality. * Universal, 32-bit PCI edge connector * Board Size: 7.0" x 3.8" * Bracket: ISA/EISA Style SCSI Termination * GPIO line disable termination feature ADVANCED SDMS SOFTWARE GIVES YOU A COMPLETE ULTRA160 SCSI SOLUTION The LSI8955U comes complete with a suite of SDMS drivers and utilities, so you get a total Ultra160 SCSI solution. Based on the software that has enabled generations of SCSI solutions, SDMS is now enhanced to fully enable the advanced capabilities of Ultra160 boards. SDMS maximizes system resources and performance by providing support for increased data speed, improved bus utilization, and AIP and CRC management. VISUAL INDICATORS * Termination power indicator TM A recent addition to the SDMS suite, SureLINK domain validation technology is available exclusively from LSI Logic. This technology ensures data integrity by intelligently testing the network before completing negotiation. SDMS supports all major operating systems, including DOS with ASPI support, Windows 95/98, Windows NT, UNIXware, SCO UNIX, OS/2, Novell NetWare, Solaris and Linux. A complete set of SCSI utilities rounds out the software, including DMI 2.0-based system management software for Windows NT, NetWare, UNIXware, Solaris and Linux, and a stand-alone or snap-in DMI browser applet. SERIAL EEPROM The LSI8955U has a 16K x 1bit serial EEPROM memory device for storing the configuration information for each channel. The SDMS software will utilize this device automatically. * SCSI activity indicator * SCSI bus active 4-pin header for off-board LEDs SOFTWARE SUPPORT * Fully supported in SDMS Release 4.6 (R) (R) * Microsoft Windows 98, NT 4.0, Windows 2000 (R) (R) (R) (R) * Novell NetWare 4.11 and 5.0 * Nextreme RAID (R) * Solaris 2.6, 2.7 - X86 * Server management support for DMI 2.0 * NT 4.0, NetWare 4.11, UnixWareTM 2.12 (R) TERMINATION Active termination is provided on the LSI8955U. Termination can be automatically enabled or disabled via an auto-termination circuit feature. The cable sensing option implemented on the LSI8955U provides the means for which termination is automatically NEXTREME RAID The LSI8955U host adapter board supports NextremeTM RAID, which includes a RAID BIOS option. Nextreme RAID delivers a cost-effective, faulttolerant, bootable solution, which meets the increased performance and data protection needs of Window NT and Windows 2000 workstations. Nextreme RAID combined with the LSI8955U is ideal for applications where high-performance, robust data protection is required.
