关于 FC拓扑-引自维基百科
http://en.wikipedia.org/wiki/Fibre_Channel
• Point-to-point (FC-P2P). Two devices are connected directly to each other. This is the
simplest topology, with limited connectivity.[1]
• Arbitrated loop (FC-AL). In this design, all devices are in a loop or ring, similar to token
ring networking. Adding or removing a device from the loop causes all activity on the loop
to be interrupted. The failure of one device causes a break in the ring. Fibre Channel hubs
exist to connect multiple devices together and may bypass failed ports. A loop may also
be made by cabling each port to the next in a ring.
• A minimal loop containing only two ports, while appearing to be similar to FC-P2P,
differs considerably in terms of the protocol.
• Only one pair of ports can communicate concurrently on a loop.
• Maximum speed of 8GFC.
• Switched fabric (FC-SW). All devices or loops of devices are connected to Fibre Channel
switches, similar conceptually to modern Ethernetimplementations. Advantages of this
topology over FC-P2P or FC-AL include:
• The switches manage the state of the fabric, providing optimized interconnections.
• The traffic between two ports flows through the switches only, it is not transmitted to
any other port.
• Failure of a port is isolated and should not affect operation of other ports.
• Multiple pairs of ports may communicate simultaneously in a fabric.

在部署虚拟化测试环境中发现 Brocade的 HBA卡直连 EMC VNX5100存储,发
现两者无法互相发现:
刚开始怀疑是存储的问题,但问了不少人都说 Brocade 的 HBA 卡不支持直
连,VNX是支持直连的,而且 VNX上的前端 FC 端口也显示到速率,证明物理层连
接是没问题的,Google一番,发现出现不少这种情况,都显示Brocade的卡不支持
直连( only FCSW),必须带交换机,后来 Google发现,新版本的 BCU3.2.1支持直
连(也就支持 FCAL,P2P),于是立刻更新 ESXI 的 Brocade HBA卡驱动,最新版的
Driver请在 Brocade官网下载
brocade_driver_esx5x_v3-2-1-0.tar
通过 SCP或 vsphere client上传到 ESXI的目录下,例如:
通过 vsphere client上传到 local datastore1/brocade
执行如下命令:
cd /vmfs/volumes/datastore1/Brocade
tar –zxh brocade_driver_esx5x_v3-2-1-0.tar
./brocade_install_esxi.sh
然后会引导安装最新的 3.2.1驱动与 BCU
安装完成后 reboot esxi
reboot之后 cd /opt/brocade/bin 执行 bcu
执行 1/0端口 拓扑改为 FCAL loop, disable->enable
然后登陆存储查看是否能识别到,OK,顺带把主机注册
OK,存储已经发现主机,然后分配 LUN给主机,主机 rescan,也没问题
