Symbios Logic announces industry's first PCI to Wide Ultra2 SCSI host adapter board;.FT. COLLINS, Colo.--(BUSINESS WIRE)--March 24, 1997-- 80 MB/s Solution Delivers High SCSI SCSI in full Small Computer System Interface Once common standard for connecting peripheral devices (disks, modems, printers, etc.) to small and medium-sized computers. SCSI has given way to faster standards, such as Firewire and USB. Data Rates with the High Performance PCI (1) (Payment Card Industry) See PCI DSS. (2) (Peripheral Component Interconnect) The most widely used I/O bus (peripheral bus). System Bus Continuing to evolve market-driven SCSI products and technology, Symbios Logic Symbios Logic was a manufacturer of SCSI host adapter chipsets and disk array storage subsystems. It was a wholly owned subsidiary of Hyundai Electronics America. It was originally a division of NCR Corporation, before NCR's takeover by AT&T. AT&T sold off the division to Hyundai. announced today the industry's first PCI to Wide Ultra2 SCSI See Ultra SCSI. host adapter Also called a "controller" or "host bus adapter," it is a device that connects one or more peripheral units to a computer. It is typically an expansion card that plugs into the bus. IDE and SCSI are examples of peripheral interfaces that call their controllers host adapters. See host. utilizing the Symbios Logic universal LVD See LVDS. LVD - Low Voltage Differential transceiver technology, LVDlink(tm). An extension of existing Symbios Logic PCI SCSI I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output solutions, the SYM8951U delivers high data rates in combination with the high- performance PCI system bus. Based on Symbios Logic's SYM53C895 Ultra2 SCSI I/O processor Circuitry specialized for I/O operations. See front end processor. , the SYM8951U provides universal Low Voltage Differential (hardware) Low Voltage Differential - (LVD) A method of driving SCSI cables that will be formalised in the SCSI-3 specifications. LVD uses less power than the current differential drive (HVD), is less expensive and will allow the higher speeds of Ultra-2 SCSI. LVD requires 3. (LVD) signaling for SCSI as well as providing legacy single-ended SCSI support. The built-in LVD transceiver, LVDlink, automatically switches between Ultra SCSI The designation for various high-speed SCSI interfaces. The original specification was Ultra SCSI, followed by Ultra2, Ultra3, etc. For details, see SCSI. 40 MB/s transfers and Ultra2 SCSI 80 MB/s transfers for all LVD devices on the bus. LVDlink addresses the workstation and server markets by allowing for greater connectivity and longer cables, with improved signal integrity and data reliability at lower cost than high-power differential products. The SYM8951U targets applications storing or transporting large block-size transfers, such as video production and editing, medical imaging, video on demand and high-performance desktop multimedia markets. By upgrading the link between servers and their storage subsystems, users can virtually double their throughput in Ultra SCSI systems (four times the throughput of Fast SCSI) and can preserve the usefulness of present equipment. "OEMs, today, can add Ultra2 SCSI to their systems, quickly, thereby reducing their time-to-market with the Symbios Logic SYM8951U host adapter solution," said Tom Lagatta, vice president of marketing for Symbios Logic. "And as Ultra2 disk drives become readily available, our solution provides OEMs a transparent upgrade to a complete Ultra2 system, including system configurations that support up to 12-meter cables and up to 16 LVD devices." The SYM8951U host adapter automatically switches modes from LVD to single-ended when single-ended devices are connected to the bus. With all LVD devices on the SCSI bus the SYM8951U automatically enters LVD mode. In single-ended mode, the SYM8951U host adapter matches the speeds of the attached SCSI devices with transfers up to 20 MB/s for Fast SCSI devices, or up to 40 MB/s for Ultra SCSI devices. With the plug-and-play features of PCI, the built-in utility features of SCSI Configured AutoMatically (SCAM) and SCSI bus and device configuration in the on-board FLASH BIOS, the bootable SYM8951U eliminates the need for jumpers, switches and allocating system DMAs, IRQs or address resources. Installing the SYM8951U Ultra2 SCSI host adapter in a SCAM environment is a simple matter of plugging into an available PCI slot, connecting the SCSI cables, and loading the operating system drivers. The SYM8951U host adapter comes with Symbios Logic's powerful SCSI Device Management Software SDMS SDMS - A query language. , which provides built-in SCAM and SCSI bus and device configuration utilities. All major operating systems, including DOS and Windows 3.1x(tm), Windows 95(tm) and Windows NT(tm), Novell Netware(tm), SCO Unix Open Server(tm), UNIXWARE(tm) and OS/2 are supported. The new one-interrupt-per-I/O Windows 95 and NT drivers provide improved system CPU CPU in full central processing unit Principal component of a digital computer, composed of a control unit, an instruction-decoding unit, and an arithmetic-logic unit. utilization. In high-performance Windows NT environments the new driver shows significant improvement in I/O throughput and CPU utilization over previous industry offerings. Multiple Symbios Logic host adapters save precious host memory resources by using only one copy of the BIOS for all adapters. Most competing solutions "stack" a copy of each host adapter BIOS in system memory, thereby reducing available system memory. Continuing Symbios Logic's technology leadership, the SYM8951U will also be offered as part of Symbios Logic's I2O-ready family of host adapters. The SYM8951U PCI Ultra2 SCSI host adapter will be shipping in production volumes in June. Pricing is set at $153.87 per board in 10K quantities. Symbios Logic creates storage management and peripheral connection solutions and provides a full spectrum of products for these solutions, including cell-based ASICs, integrated circuits, host adapters and storage systems as well as supporting software drivers and utilities. The Company focuses on developing technology partnerships with its customers and vendors, including original equipment manufacturers and resellers in the networked computing, peripherals and communications markets. Formed in 1995, Symbios Logic is a wholly owned, independently operated subsidiary of Hyundai Electronics America. The Company has a total worldwide employment of 2,300 with operations in Wichita, Kansas, Fort Collins (headquarters) and Colorado Springs, Colorado The City of Colorado Springs is the second most populous city (after Denver) in the state of Colorado and the 48th most populous city in the United States.[4] The city is the county seat of El Paso County. , plus 20 worldwide sales offices. Company revenue in 1996 was approximately $600 million. For further information, please call 1-800-856-3093 or visit our Web site at www.symbios.com .
