Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output PRO Provides Twice the Raw Processing Plus Provides Bus Width/Bus Speed Flexibility SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif.--(BUSINESS WIRE)--June 7, 1999-- Advanced System Products, Inc. (AdvanSys) the company advancing connectivity for the office, home and enterprise, today announced availability of its premier Dual Channel 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. Ultra/160/m chip, the ASC ASC Ambulatory surgery center, see there 38C1600, which can support a combined data transfer rate of 320MB/s. The revolutionary ASC38C1600 takes I/O performance and Bus interface flexibility to the next level. The AdvanSys patented architecture and I/O PRO(TM) technology deliver twice the raw processing power of competing products as measured by MIPS (Million Instructions Per Second) The execution speed of a computer. For example, .5 MIPS is 500,000 instructions per second; 100 MIPS is a hundred million instructions per second. and sequential I/O on the Iometer benchmark. And it offers users bus interface choices for migration, technology advances, and growth needs. The ASC38C1600's truly flexible bus interface allows users to connect with any combination of 32-bit or 64-bit and 33MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. or 66MHz PCI (1) (Payment Card Industry) See PCI DSS. (2) (Peripheral Component Interconnect) The most widely used I/O bus (peripheral bus). . The independent Dual Channels can be controlled by independent device drivers, making it ideal for Raid or cluster configurations, as well as the premier choice for high performance Ultra 3 applications requiring connectivity to many devices (up to 30) or connectivity of Ultra2 or Ultra 3 and legacy devices. "AdvanSys is excited to offer yet another industry leading SCSI host product based on AdvanSys leading-edge patented architecture," states George Brecht George Brecht (born George MacDiarmid, Halfway, Oregon, United States 1924) is a minimalist artist and composer (although not in the conventional sense) and a professional chemist who has worked as consultant for such companies as Pfizer, Johnson & Johnson, and Mobil Oil to , AdvanSys vice president of marketing. "With the design expertise and industry knowledge the AdvanSys engineering team possesses, AdvanSys has once more leap-frogged the competition in developing a next generation SCSI product that will provide its customers with a competitive edge. With the ASC38C1600 AdvanSys customers have the highest performance Ultra/160/m chip available combined with designed in flexibility for future product enhancements and migration needs. OEM's and System Integrators who choose the AdvanSys ASC38C1600 can take advantage of the highest performing, most cost effective, easiest to use and install product available today. Which translates into end users who will be happy for years to come." The AdvanSys ASC38C1600 utilizes two 40MIPS application specific Reduced Instruction Set Computing Noun 1. reduced instruction set computing - (computer science) a kind of computer architecture that has a relatively small set of computer instructions that it can perform reduced instruction set computer, RISC (RISC RISC in full Reduced Instruction Set Computing Computer architecture that uses a limited number of instructions. RISC became popular in microprocessors in the 1980s. ) processors in a dual channel architecture to support full multi-threading and capability to process up to 120,000 I/O commands per second. Couple this with a DMA (1) (Digital Media Adapter) See digital media hub. (2) (Document Management Alliance) A specification that provides a common interface for accessing and searching document databases. bus master PCI architecture used with AdvanSys' application specific RISC processors, and the ASC38C1600 can transfer data while significantly reducing host involvement in I/O transfer requiring a maximum of only one interrupt per I/O operation. This results in sequential I/O that is 50% faster than is typically found in competitive products. The industry-leading performance of the AdvanSys ASC38C1600 is ideally suited for workstation, server, RAID, storage cluster, data mining or other bandwidth intensive applications.

Interrupt handlers typically deal with low-level events in the hardware of a computer system such as a character arriving at a serial port or a tick of a real-time clock. . AdvanSys has used interrupt technology in its earlier SCSI product (Fast, Ultra and UltraWide). The ASC38C1600 implements I/O PRO which is an optimized second generation interrupt coalescence technology. In a February 1999 comparative test, using the Intel Iometer performance benchmark, AdvanSys outperformed competing top tier SCSI products. The AdvanSys SCSI product had the best (lowest) 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 for overall I/O performance on high-end server systems running NT 4.0 with large numbers of disks when compared with other top tier SCSI competing products. The AdvanSys patented architecture, utilizing an integrated RISC engine manages all handshakes with the SCSI peripheral devices. A DMA bus master circuit transfers data between the SCSI device and main memory at the maximum possible speed of the system bus, requiring no intervention from the host. Additional Highlights of the ASC38C1600 The AdvanSys ASC38C1600 incorporates cyclic redundancy check (algorithm) cyclic redundancy check - (CRC or "cyclic redundancy code") A number derived from, and stored or transmitted with, a block of data in order to detect corruption. (CRC (Cyclical Redundancy Checking) An error checking technique used to ensure the accuracy of transmitting digital data. The transmitted messages are divided into predetermined lengths which, used as dividends, are divided by a fixed divisor. ) to assure data integrity, domain validation Domain Validation is part of the SCSI standard. It describes how to negotiate the best possible transfer agreement between two devices. There are three different messages that can be sent:
AdvanSys combined its vast experience in developing connectivity solutions with a viable solution for preserving current SCSI investments and future SCSI requirements. All of the AdvanSys products support legacy SCSI devices and are designed and engineered to support today's latest SCSI architecture and technologies, as well as future technology breakthroughs. So emerging bandwidth-intensive applications such as Internet/Intranet, scientific modeling and simulation, data mining and real-time video will find the ASC38C1600 the perfect solution. The AdvanSys proprietary software architecture reduces incremental software development required for each successive SCSI generation resulting in higher reliability. AdvanSys software is designed to provide software portability across system platforms. The AdvanSys architecture simplifies driver software requirements while ensuring driver transparency for new product generations. While competitive products may require months in porting software to new platforms, the AdvanSys architecture allows for completion in weeks. This ensures that the AdvanSys user always has the most advanced technology available and that there is backward compatibility with the users installed legacy investment.
