DPT named finalist in BYTE'S "Best of COMDEX Fall '95 Award" for SmartCache IV SCSI host adapters.Processing Technology (DPT), a pioneer and leading supplier of high-performance 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. and Redundant Array of Independent Disks (RAID) solutions, was named one of three finalists in BYTE Magazine's "Best of COMDEX/Fall '95" award in the peripherals category for its revolutionary line of SmartCache IV SCSI host adapters. Award winning SmartCache IV at Comdex/Fall '95 SmartCache IV, the next generation of DPT's award-winning SmartCache family of SCSI host adapters, combines the latest advancements in intelligent input/output (architecture) Intelligent Input/Output - /i:-too-oh/ (I2O) A specification which aims to provide an I/O device driver architecture that is independent of both the specific device being controlled and the host operating system.

The new SmartCache IV products debut at Booth No. 2668 at the Las Vegas Convention Center The Las Vegas Convention Center is owned and operated by the Las Vegas Convention and Visitors Authority and is located in Clark County, Nevada.

"BYTE's recognition reinforces DPT's position as the premier technology pioneer in I/O scalability and disk fault tolerance See fault tolerant. (architecture) fault tolerance - 1. The ability of a system or component to continue normal operation despite the presence of hardware or software faults. This often involves some degree of redundancy. 2. ," said DPT Vice President of Distribution Sales and Marketing John (Johnny) Cardosi. "DPT is still the only industry player to provide RAID and cache upgradable SCSI host adapters. "Unlike competitive SCSI adapters, SmartCache IV's unique combination of a high-performance SCSI adapter and upgradability to RAID & caching provides a cost-effective, hardware-based solution with a logical growth path to enable your system to grow as your business needs change. That's why we think SmartCache is the Smart Choice. It's a wise investment that pays now and keeps paying benefits later." The Hard Facts About Hardware- vs. Software-Based RAID RAID is the only technology that allows users to increase capacity and performance proportionately...and add fault tolerance. Industry analysts and experts frequently cite DPT as the "unchallenged market leader" in hardware-based RAID and caching. SCO (The SCO Group, Lindon, UT, www.sco.com) A leading vendor of Unix operating systems for the x86 platform. SCO had also offered Linux, but abandoned the line in the spring of 2003. The SCO Group is the combination of two companies: Utah-based Caldera, Inc. World (July 1995) noted DPT's technology increased system throughput by approximately four-times. This performance and reliability sharply contrasts software-based RAID, which is inherently slower than hardware-based RAID. Software RAID "steals" 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. cycles to power the calculations needed for RAID, thereby inhibiting overall server performance. Consequently, the modest initial savings in "hard" dollar costs of software vs. hardware RAID are lost due to lower server performance and lost employee/server productivity. This cost-gap closes radically when the demand for performance placed on the server CPU necessitates a system upgrade to maintain acceptable network performance. SmartCache IV's integrated RAID and Caching Module offers a cost-effective, hardware-based RAID alternative for mid-range servers. SmartCache IV Features & Benefits SmartCache IV's unique design makes it the industry's only upgradable half-size SCSI adapter. DPT's new RAID & Caching Module (RC4040) attaches to the end of a SmartCache IV adapter via an innovative "docking" design. This optional module converts the SmartCache IV adapter to a full-function RAID controller A disk controller card that supports one or more RAID configurations. Originally only for SCSI drives, RAID controllers have become very popular for PATA and SATA drives. See RAID. supporting RAID levels 0, 1 and 5 (including dual-level arrays) with support for up to 64MB of hardware cache. The resultant combination provides a cost-effective, hardware-based RAID and caching alternative for small and mid-range servers. Dual-level arrays provide for highly flexible array configurations and virtually unlimited expansion capabilities. Users add functionality as they need it, and both the functionality and the cost of new functions are incremental. "Other proposed solutions for the mid-range server market do not provide the power and flexibility that SmartCache IV -- with its unique RAID and caching upgradability -- offers," said Cardosi. "The SmartCache IV family of SCSI host adapters have been specifically designed to meet the growing I/O demands of multi-user, multi-tasking, and networked environments, as well as I/O-intensive desktop applications such as color pre-press and multimedia." The SmartCache IV family includes: one ISA-to-SCSI, two EISA-to-SCSI and eight PCI-to-SCSI adapters (for PCs and Power Macintosh computers). The SmartCache IV PM2041W (ISA (1) (Instruction Set Architecture) See instruction set. (2) (Interactive Services Association) See Internet Alliance. (3) (Internet Security and Acceleration) See .NET. ), PM2042W (EISA (Extended ISA) Pronounced "ee-suh." A PC bus standard that extends the 16-bit ISA bus (AT bus) to 32 bits and provides bus mastering. ISA cards can plug into an EISA slot. ), PM2044W (PCI (1) (Payment Card Industry) See PCI DSS. (2) (Peripheral Component Interconnect) The most widely used I/O bus (peripheral bus). ), PM2044UW (PCI), PM2044W-MAC (PCI) and PM2044UW-MAC (PCI) adapters are lower-cost SCSI solutions designed for desktop systems and workgroup/department server environments, list prices starting as low as $265. These adapters feature a new DPT Application Specific Integrated Circuit (ASIC (Application Specific Integrated Circuit) Pronounced "a-sick." A chip that is custom designed for a specific application rather than a general-purpose chip such as a microprocessor. ), co-developed by DPT and Motorola, which integrates a M68000/20MHz (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. processor to yield greater speed and reliability. The higher performance SmartCache IV PM2142W (EISA), PM2144W (PCI), PM2144UW (PCI), PM2144UW-MAC (PCI), and PM2144W-MAC (PCI) adapters employ an on-board M68020/20MHz processor, providing up to three times more processing power for more demanding I/O environments. On-board processing power increases overall I/O system performance by reducing the time required to process SCSI commands by as much as 50 percent. All SmartCache IV adapters feature: SCSI-3 compliance, support of 16-bit Wide SCSI providing throughput of up to 20Mbytes/second, (compared to 10Mbytes/second with standard 8-bit Fast SCSI), 100% compatibility with existing DPT software drivers, optional hardware RAID and caching support for increased performance and disk fault tolerance, and SCSI Configured Auto-Magically (SCAM) levels 1 and 2. SCAM, a protocol which performs SCSI device ID assignment without the use of jumpers or similar configuration settings, sets new standards for SCSI installation and ease-of-use. Ultra-Wide SCSI models with throughput up to 40Mbytes/second (scheduled for launch in Q1 1996) are also included in the SmartCache IV product family. DPT's caching technology delivers enhanced I/O performance and is designed to be a powerful complement to software caching schemes like those found in Windows '95, OS/2, NetWare, Windows NT, and Unix. The SmartCache IV RAID and caching module (RC4040) supports up to 64Mbytes of hardware cache and accepts either standard 72-pin SIMMs or DPT's Error Correcting Code (ECC (1) (Error-Correcting Code) A type of memory that corrects errors on the fly. See ECC memory. (2) (Elliptic Curve Cryptography) A public key cryptography method that provides fast decryption and digital signature processing. ) SIMMs. DPT's ECC-protected SIMMs, available in 4MB and 16MB capacities, feature a unique ECC algorithm that corrects up to 32-bit memory errors. Additional SmartCache IV Features Additional fault tolerance features of the SmartCache IV family include: on-board alert capabilities, integral diagnostics and bad block reassignment. Global Hot-Spare support allows for easy on-line replacement and rapid recovery from a disk failure.
