VMIPMC-5790 PMC Dual-Channel Ultra160 SCSI Adapter • Dual-channel Ultra160 SCSI features — Supports dual-channel Ultra160 SCSI — 64-bit, 33/66 MHz PCI interface — Theoretical 160 Mbyte/s each channel — 64-bit addressing supported through Dual Address Cycle (DAC) — Compliant with PCI 2.2, PCI Power Management 1.1, and PC99 — Double transition clocking for 160 Mbyte/s throughput — Cyclic redundancy check (CRC) that protects data — Domain validation — Asynchronous information protection (AIP) — Covers all nondata, including command, status, and messages — SCSI interrupt steering logic (SISL) alternate interrupt routing for RAID applications INTRODUCTION — The VMIPMC-5790 is a dual-channel Ultra160 SCSI host bus adapter (HBA) board based on the PMC form factor. The VMIPMC-5790 HBA provides two independent external Ultra160 SCSI channels that support both LVD and single-ended SCSI operations. down until the connection becomes error-free. In this way, The VMIPMC-5790 leverages the LSI SYM53C1010 PCI if a connection can be made it will be made. The highly dual-channel Ultra160 SCSI controller. The single-chip, integrated design promotes high reliability, low power true multifunction PCI device connects directly to a 64- or consumption, and low cost. 32-bit, 66 or 33 MHz PMC bus. This presents one electrical Ultra160 SCSI Software Support: load, while functioning as a single 64- or 32-bit PCI DMA bus master. The VMIPMC-5790 includes an easy-to-use • Windows NT® on-board configuration utility, which allows the viewing • Windows® 2000 and changing of default configuration settings for the host adapter and SCSI devices. • Linux • Solaris PRODUCT OVERVIEW — The VMIPMC-5790 • VxWorks dual-channel Ultra160 SCSI HBA is specifically designed for storage on workstations, servers systems, computer clustering applications and, due to its high network TECHNICAL SPECIFICATIONS bandwidth, is well suited for telecom, signal processing, and SCSI Transfer Rate: Ultra3 at 160 Mbyte/s per distributed computing applications. The independent SCSI channel controller supports wide Ultra160 SCSI synchronous transfer rates up to 160 Mbyte/s on a low-voltage Host Bus Transfer Rate: 64-bit bus master DMA differential (LVD) SCSI bus. Integrated LVD link maximum burst data transfers up to 264 Mbyte/s transceivers support both LVD and single-ended signals (PCI - 64/33 MHz) or 528 Mbyte/s (PCI - 64/66 MHz) with no external transceivers required. Fast SCSI, Ultra SCSI, Ultra2 SCSI, and Ultra160 SCSI are all supported by Host Bus Signaling: Supports 5 or 3 V signaling the VMIPCI-5790. The 8 Kbyte of internal RAM for On-Board SCSI-3 RAM: 8 Kbyte (internal) SCRIPTS instruction storage allow all accesses to remain internal, reducing the time spent on the PCI bus. A 944 byte DMA FIFO allows the device to efficiently burst up to 512 bytes across the PMC bus. The VMIPMC-5790 Ordering Options supports cyclic redundancy checks (CRC), which is far Dec. 19, 2000 800-755790-000 A ABC – D E F superior for detecting errors during high-speed data VMIPMC-5790 –000 – transfers. CRC is a proven international standard that ABC = 000 (Options reserved for future use) checks all transferred data and adds significantly to data Ultra160 SCSI Connector Data reliability. The VMIPMC-5790 also supports domain 68-pin VHDCI external (2) validation, which effectively manages the connection to Cable Specifications reduce installation problems.
