Benefits

I Supports bandwidth to allow wire-speed performance of two Gigabit Ethernet connections

I Lowest latency solution â a PCI/PCI-X bridge component is not required to implement a dual port design

I Application flexibility in LOM or embedded use

I 64-bit addressing for systems with more than 4GB of physical memory

I No external FIFO memory requirements; I FIFO size tunable to the application

I Reduced frame loss due to receive FIFO overrun

I Efficient PCI-bandwidth usage

I Efficient usage of PCI bandwidth

I Reduces the number of interrupts generated by receive and transmit operations

I Improves throughput performance and CPU utilization

I High throughput for large data transfers on networks supporting jumbo frames

I Enables IT staff to easily create multiple virtual LAN segments

I Reduced board space and lower power dissipation

I Automatic link configuration including speed, duplex, and flow control

I Robust 1000Mb/s performance in noisy environments and despite severe cable installation problems

I Easier network installation and maintenance

I Solution for server blade backplane connections and Fiber Gigabit Ethernet

I Increased throughput and lower CPU utilization. Compatible with large send

offload feature found in Windows* 2000 and Windows* XP

I 16 exact matched (unicast or multicast)

I Promiscuous (unicast/multicast) transfer mode

I Enables IPMI, and ASF implementations

I Provides alerting and remote-control capabilities with standardized interfaces

I PCI power management capability requirements for PC and embedded applications

I Packet recognition and wakeup for network adapter and LOM applications

I Low power in standby states

I Supports power-down states without software assistance

I Indications for link speed, activity, duplex, collisions, pause by flow control, PCI speed, PCI width, and

port ID on each port

I Allows design customization without affecting software drivers

I Simplified power supply design
