Introduction Product Overview Product Overview Gigabit Ethernet is a high-performance Ethernet networking solution for HP servers and workstations. The LAN adapters are data link adapters that support the IEEE 802.3z standard for 1000Base-SX operation over multimode fiber, and the IEEE 802.3ab standard for 1000Base-T operation over 4-pair Cat-5 or Cat-5E UTP copper wiring. The Gigabit Ethernet intelligent adapters are designed to maximize host CPU efficiency by performing functions such as TCP/IP

Configuring Gigabit Ethernet Parameters Understanding the Gigabit Ethernet Parameters in all. One of the two parameters specifies the number of data buffers that the card must transmit (or receive) before interrupting and the other specifies the number of system clock ticks that must elapse before interrupting. The four tuning parameters are summarized in the following table. Table 2-1 Performance Tuning Parameters Name Range Default Units send_max_bufs 1 – 128 16 (for gelan) # of buffers 10 (for i
