In addition to full modem support, the highly integrated adapter design provides four high-speed intelligent channels. Its on-board memory eases internal data flow and offloads communication functions from the CPU. The result is more efficient data buffering, greatly improving overall system performance. By enabling 32-bit-wide PCI Bus data transfers, this adapter also allows for maximum throughput, ensuring the best system utilization.Multiple High Speed Serial Interface controller cards are supported by the adapter's multi-threaded, streams software driver. The streams-based driver interface is also compatible with other SunLink products. Additional driver utilities enhance network functionality by providing initialization, loop-back testing, and status monitoring functions. For the thousands of companies acquiring Sun's latest PCI Bus-based computing technology in offices around the world, now there's a high-speed, cost-effective, flexible solution for remote connectivity. The Sun PCI High Speed Serial Interface Adapter. There's no better way to turn your LANs into a WAN.
