@eikeime 再请教个问题,如下图所示,HP ML310e Gen8 v2塔式服务器主板上有一个Slot 2 PCIe2 x8 (1) 扩展槽,物理接口是x8,链路速度是2.0 x1,我想插个4口千兆网卡HP NC366T 1Gb 4-port Ethernet Server Adapter,也就是HP OEM版的I350-T4,不知是否可行
在HPE支持中心官网查了一下HP Ethernet 1Gb 4-port 366T Adapter - Specifications
Technical specifications
Communications processor Intel Ethernet Controller I350
Data rate Four 1GbE ports, each at 2 Gb/s full duplex; 8 Gb/s aggregate full duplex theoretical bandwidth. 10/100/1000 Mb/s, Full-duplex
Data path Four lane (x4) PCI Express compatible with x1, x4, x8, and x16 PCI Express slots
Connector RJ-45 (Four)
Cable distance Up to 328 ft (100 m)
Wiring Category 5 (CAT-5) or better twisted-pair cabling
Bus type PCI Express v2.0 (Gen2.1 x4)
Form factor Low profile card with both full height (pre-installed) and half height brackets included in kit
IEEE Compliance 802.3, 802.3ab, 802.3u, 802.3x, 802.3ad, 802.1q, 802.3az, 1588, 802.1as
其中Data path这项描述道Four lane (x4) PCI Express compatible with x1, x4, x8, and x16 PCI Express slots,是指兼容PCIe 2.0 x1还是3.0 x1?我知道4个千兆口无法跑满,毕竟PCIe2 x1带宽在那限制着,实际家庭应用环境就算是软路由也很少会同时将4个口跑满,这里担心的是卡插上能不能点亮,不会开机报错吧
