Abstract: A system and method for link detection and link initialization across a range of communication media is disclosed. In an embodiment, the method includes intercepting, by a subcontroller of a first storage element, an attempt by a controller of the first storage element to establish communication with a second storage element via a first communication medium. In response to the intercepting of the attempt, a link initialization signal is provided for transmission to the second storage element via a second communication medium. The second communication medium is independent of the first communication medium. When a response is received from the second storage element indicating a successful link initialization, an indication of success is provided from the subcontroller to the controller. The indication of success corresponds to the first communication medium. In one example, the controller includes an SAS controller, and the second communication medium is an optical communication medium.

Abstract translation: 公开了一系列通信介质的链路检测和链路初始化的系统和方法。 在一个实施例中，该方法包括由第一存储元件的子控制器拦截第一存储元件的控制器尝试经由第一通信介质与第二存储元件建立通信。 响应于尝试的截取，提供链路初始化信号以经由第二通信介质传输到第二存储元件。 第二通信介质独立于第一通信介质。 当从第二存储元件接收到指示成功的链接初始化的响应时，从子控制器向控制器提供成功指示。 成功的指示对应于第一通信介质。 在一个示例中，控制器包括SAS控制器，第二通信介质是光通信介质。
