The Talon1214TM is a dual-port Gigabit Ethernet (GigE), low profile PCI-Express copper network interface card (NIC) designed for a wide range of desktop, workstation, server, storage, and security system applications. It's designed to work in the short distance LAN applications. The board is low cost and suitable for small, medium, or large size businesses.
LeWiz's Talon1214TM card is designed to maximize the performance of each port to full wire rate in both directions. Each of the GigE port has a dedicated MAC with its own transmit/receive engines, DMA, and buffers. Each of the port has advance offload functions such as TCP/UDP transmit segmentation, checksum processing, iSCSI/NFS assist benefiting applications such as video, iSCSI, NAS storage, VoIP, and others. The ports have advanced interrupt handling scheme maximizing the efficiency of multi-processor or multi-threaded systems.
Each port is capable of 1 Gbps and is backward compatible with existing Ethernet networks. The board takes advantage of the high performance PCI-express bus available in many clients (desktop, workstations), servers, storage, and security systems. The x1 PCI-Express bus interface on the Talon1214TM board has 1 lane, and can be used with x1, x4, x8, or x16 PCI-Express slots.
Internally, the Talon1214TM card has wide internal on-chip data paths eliminate performance bottlenecks. It has a combination of parallel and pipelined logic architecture optimized for Gigabit Ethernet with independent transmit and receive queues. The Talon1214TM board efficiently handles packets with minimum latency. It uses efficient ring buffer descriptor data structures, with up to 64 packet descriptors cached on chip. A large 48 KByte per port on-chip packet buffer maintains superior performance. In addition, using hardware acceleration, the controller offloads tasks from the host, such as TCP/UDP/IP checksum calculations and TCP segmentation/large send offload.
The physical size of the board is tiny - about the physical size of a typical credit card but packing 2 GigE ports. Its small size is ideal for ANY small form factor computing systems.
The Talon1214TM has a full range of loadable device driver support for many different operating systems from Windows, to Linux, to Solaris. It simply works every where and easy to deploy.
