仲裁環路

仲裁環路 ^[1]  （arbitrated loop），如果算上連接到一個光釺連接控的端口它支配 127 個設備。僅僅一個連接可能是一個連接孔。設備在一個單行道環方式下被連接 也叫做 FC-A L 一個不需要光纖通道轉換器光纖通道拓撲。

A private arbitrated loop is a configuration where up to 126 devices can be attached. The attachment point called NLport

(loop ports). FC-AL is a low cost connectivity solution because it does not require expensive switching devices.

Instead low cost hubs are used to increase server and storage connectivity. Hubs have won wide acceptance in JBOD

(Just a Bunch of Disks) environments, because just as JBOD costs less than enterprise storage, hubs cost less than

switched fabric.
