The demonstration, which ran SCSI over Schedule Transfer (ST) protocol with a peak data transfer rate of 637.5 Mbytes per second, is the framework for the highest bandwidth storage area network (SAN) ever configured with commercially available products, the three partners claim. The demonstration utilized a storage subsystem comprised of eight Ciprico 7000 Series Fibre Channel RAID disk arrays connected to eight separate Fibre Channel ports on a GENROCO TURBOstor Gbyte System Network (GSN) Storage Array Controller. Schedule Transfer (ST) protocol was run between the GSN storage and an SGI Origin 2000 configured with their XIO GSN adapter. The GENROCO TURBOstor controller serves as a proxy for the ST protocol. Host system SCSI commands are transported over GSN using ST and are then translated to Fibre Channel SCSI commands by the hardware. GENROCO GSN Storage Array Controllers employ the SGI SuMAC GSN and Hewlett-Packard Tachyon Fibre Channel ASICs, as well as the Patriot Scientific PSC1000 Java Engine CPU. According to the companies the results are just the 'tip of the iceberg'. Over the next several months, they expect to reach transfer rates approaching 800 Mb/sec and demonstrate access to the storage via Gigabit Ethernet, HIPPI, and ATM using ST software for Compaq, Sun, IBM, and Intel/NT based clients. ST is a new network protocol designed to allow many times higher bandwidth with much lower host platform overhead than TCP/IP or any other current industry standard. An ST data movement over any type of network commences, or is "scheduled", only when a ready transmit buffer is matched by an equal sized, ready receive buffer at the destination. This allows the sending and receiving engines at endpoints of a network to operate at the highest possible speed and efficiency by eliminating buffer overruns and underruns. GSN is the highest bandwidth and lowest latency open system industry standard (ANSI HIPPI-6400-PH, ANSI NCITS 323-1998), providing full duplex 6400 Mbit (800 Mbyte) per second channels of error-free, flow controlled data. The technology is ideal wherever organizations require timely movement of large amounts of information. The ANSI standard provides for interoperability with disparate technologies including Ethernet, Fibre channel, ATM, HIPPI-800, and other standards. The GSN fabric operates at a full duplex data rate of 1.6 Gbytes per second making it a backbone for multiplexing Fibre Channel storage data streams. It would require nearly 1300 sixteen port Fibre Channel switches to produce the non-blocking bandwidth of a single 32 port GSN switch. http://www.findarticles.com/p/articles/mi_m0EIN/is_1997_Sept_16/ai_19757249 Patriot Scientific Announces Design Win With GENROCO; PSC1000 ShBoom Microprocessor To Increase Data Transfer Rates by 2,000 Percent Business Wire, Sept 16, 1997 SAN DIEGO--(BUSINESS WIRE)--Sept. 16, 1997--Patriot Scientific Corp. (OTC:PTSC) Tuesday announced that it has received a design win that will result in the sale of its PSC1000 ShBoom microprocessors to GENROCO Inc. (OTC:GRCI). The 32-bit RISC microprocessor will be built-in to the fourth-quarter shipment of GENROCO's products. The PSC1000 will initially appear in GENROCO's TURBOfibre PCI Fibre Channel Controller. GENROCO has plans to use the microprocessor in its upcoming product line, making the majority of its more than 20 next-generation controllers PSC1000-based by mid-1998. Carl Pick, chairman and chief executive officer of the Wisconsin-based firm, said: "GENROCO has chosen the Patriot Scientific PSC1000 32-bit 100 MHz RISC microprocessor as the heart of our next-generation controllers because of the chip's low cost, small size and high performance. "The PSC1000 is the key component which will allow new GENROCO modules to execute firmware over 20 times faster than current offerings, allowing us to readily scale the technology from present gigabit to future gigabyte per second bandwidths." GENROCO considered many microprocessor chips, such as Digital Semiconductor's StrongArm and Intel's i960, before deciding on Patriot Scientific's stack architecture in conjunction with the FORTH development system. "The PSC1000 runs high-bandwidth, real-time applications faster and more efficiently than direct instruction chips," said Pick. "We even compared real-time code on a 500 MHz, several-hundred-dollar Alpha chip against the PSC1000, and in most of the important cases for us, the PSC1000 was faster. Patriot's technology was exactly what we needed to ensure the performance and flexibility of our next-generation controllers." "We've developed a low-cost, extremely high-performance microprocessor that is perfect for multi-task processing involving high-bandwidth and real-time embedded applications," said Phil Morettini, vice president, sales and marketing of Patriot Scientific Corp. "GENROCO's next-generation controllers will lead the industry in high data transfer rates, and the PSC1000 will make both large and small packet transfers faster and more efficient." GENROCO is the premier supplier of high-performance storage and network interfaces for PCI and Sbus-based computer systems. The company manufactures Fibre Channel, HIPPI, Ultra SCSI and DVB products for such platform vendors as Fujitsu, Tektronix, Digital Equipment Corp., Hewlett-Packard and Sun Microsystems. These organizations, in turn, sell into high-end applications that require extraordinarily high data transfer rates such as digital video, 3-D seismic and satellite imaging. GENROCO's product line is based on its sophisticated and flexible proprietary TURBOfibre architecture, which has been awarded U.S. Patent No. 5,420,984. Additional GENROCO information is available at www.genroco.com/ . Founded in 1987, Patriot Scientific Corp. designs, manufactures and markets high-performance ISDN Basic Rate and Primary Rate products for digital communications, a 32-bit microprocessor targeted at the Internet appliance and traditional embedded systems markets, and ground-penetrating radar and ionized gas antenna technologies.
