VIA VT82C686B South Bridge VIA DriveStationTM Controller Suite The VIA DriveStationTM Controller Suite in the VIA VT82C686B provides the most comprehensive set of high-performance integrated storage interface technologies available on the market today. It not only enables high-speed 300MB/s dual channel connections to new generation Serial ATA Hard Drives while retaining support for today's Parallel ATA-133 IDE devices, but also combines exceptionally fast disk data transfer rates and optimal data integrity with easy installation and manageability through the VIA V-RAID controller interface. VIA DriveStationTM Serial ATA Controller The VT82C686B South Bridge offers full support for the latest SATA specification enhancements as defined by SATA-IO, including support for 3 Gb/s transfer rates, Native Command Queuing (NCQ), port multipliers, staggered spin-up and hot plug connections. Multiple SATA Ports The VT82C686B South Bridge features four SATA ports for direct connection to up to four SATA master devices featuring the latest 3. 0Gb/s transfer rates while remaining backwards compatible with devices featuring 1. 5Gb/s data transfer rates. It is also possible to configure devices in two separate master/slave connections (a total of four drives), with the master drive data transfer rate of 3Gb/s, and a slave drive at 1. 5Gb/s. Figure: 3 SATA Internal Architecture Native Command Queuing (NCQ) Native Command Queuing (NCQ) increases storage performance by allowing supporting drives to deal with more than one command at a time, while dynamically reordering the commands for maximum efficiency. NCQ minimizes the number of I/O interrupts a server makes on the drive when carrying out multiple commands, allowing it to complete 32 commands without interruption. Without NCQ running, the host interrupts the process before each 5 Copyright © VIA Technologies, Inc, 2005. Third party brands and names are the property of their respective owner. VIA VT82C686B South Bridge command. The pin-compatible design approach of VMAP Express allows the VT82C686B South Bridge to be paired with mature VIA North Bridges, such as the VIA K8M800/K8T800/K8T800 Pro for the AMD Athlon 64 platform, the VIA PM800/PT800/PT880 for the Intel platform, the VIA CLE266/CN400 for the VIA C3TM-M, VIA C3TM and VIA EdenTM processors as well as the latest VIA VN800 for the VIA C7-MTM processor. In combination with the VT82C686B South Bridge, these platforms can support the latest PCI Express peripheral devices. USB 2. 0 The VT82C686B enhances connectivity options with its support for eight high-speed USB2. 0 ports, delivering forty times the bandwidth of USB 1. 1. The VT82C686B includes four root hubs with eight function ports featuring integrated physical layer transceivers. All eight ports support a full range of USB 2. 0 and USB1. 1 devices, and achieve data transfer rates of up to 480Mb/s. The USB controller allows hot plug and play and isochronous peripherals to be inserted into the system with universal driver support. The controller also implements legacy keyboard and mouse support so legacy software can run transparently in a non-USB-aware OS environment. Network Controller The VT82C686B features industrial strength networking capabilities courtesy of an integrated VIA IEEE 802. 3 compliant 10/100Mb/s 32-bit PCI bus master Ethernet MAC with standard MII interface to an external PHYceiver. With native driver support ensuring instant connectivity, the reliable Fast Ethernet controller is ideal for both enterprise class and home networking applications. PCI Interface & LPC Bus Featuring a PCI 2. 2 compliant PCI controller, the VT82C686B offers support for up to six PCI masters, and supports a full range of legacy controllers, including Serial and Parallel ports, Keyboard and PS2 mouse. 11 Copyright © VIA Technologies, Inc, 2005.
