Introduction (Back to top)
Silicom Silicom Gigabit Ethernet Bypass servers adapter are PCI-Express X4 network interface cards that contains two independent Gigabit ports on one PCI-E adapter.
Silicom's Gigabit Ethernet Bypass server adapters are designed with optical or copper bypass circuitry in order to provide maximum up time for the network .
Silicom's Gigabit Ethernet Bypass server adapters can Bypass its Ethernet ports on a host system failure, power off, or upon software request. In Bypass mode , the connections of the Ethernet network ports are disconnected from the interfaces and switched over to the other port to create a crossed connection loop - back between the Ethernet ports. Hence, in bypass mode all packets received from one port are transmitted to other port and vice versa. This feature enables to bypass a failed system and provides maximum up time for the network.
Silicom's Gigabit Ethernet Bypass server adapters include an on board WDT (Watch Dog Timer) controller. The adapter's software drivers or software application can write commands to the on board WDT controller. The adapter's software drivers, WDT controller and the Bypass circuitry provide an interface that control and manage the mode of the adapter.
Silicom Gigabit Ethernet Bypass server adapters have an integrated hardware acceleration that performs TCP/UDP/IP checksum offload and TCP segmentation. The host processing offloads accelerators frees CPU for application processing
Silicom's PXBPI-Series are adapters are based on Intel 82571 / 82546 Dual port Gigabit Ethernet MAC+PHY of Intel Controller .

呵呵 动作真快
？你要买去用还是干吗？要不要我找渠道商帮你联系一下？ 原帖由 Lucifer 于 2007-7-6 12:29 发表 http://www.panabit.com/forum/images/common/back.gif？你要买去用还是干吗？要不要我找渠道商帮你联系一下？
好呀。
有朋友想装Panabit（高端的），但是缺bypass功能，所以比较着急。
如果有其他的使用Intel芯片的支持bypass的网卡也可以。
谢谢先！ 哦要光口的是吗？我看明天去帮你问问 原帖由 Lucifer 于 2007-7-6 13:42 发表 http://www.panabit.com/forum/images/common/back.gif

哦哦我怎么看到点端倪呢呵呵支持6.x已经做好了吗？ 今天帮你问了，告诉我大连没有这种卡。说沈阳可能有。
但是我估计又要和上次一样的在深证能订到货。不知道你们是必须要这个东西吗？要是能联系到我给你们定一块？ 原帖由 Lucifer 于 2007-7-9 11:59 发表 http://www.panabit.com/forum/images/common/back.gif
