摘要： A method for generating and communicating file system hints. The method may include receiving an I/O request from a file system layer and checking the I/O request for file system contextual information. The method may also include accessing the file system layer to determine attributes of the file system contextual information and receiving the attributes of the file system contextual information from the file system layer. The method may further include analyzing attributes of the file system contextual information and generating a hint based upon analyzing the attributes of the file system contextual information. The method may include a mechanism to provide weight-age of data passed from the application. The hint may be associated with the I/O request, and the hint may comprise hotness information to increase efficiency of data accessibility at a lower level storage tier. The method may include sending the hint to the lower level storage tier.

摘要翻译： 一种生成和传送文件系统提示的方法。 该方法可以包括从文件系统层接收I / O请求并检查对文件系统上下文信息的I / O请求。 该方法还可以包括访问文件系统层以确定文件系统上下文信息的属性并从文件系统层接收文件系统上下文信息的属性。 该方法还可以包括分析文件系统上下文信息的属性并基于分析文件系统上下文信息的属性来生成提示。 该方法可以包括提供从应用程序传递的数据的权重的机制。 提示可能与I / O请求相关联，并且提示可以包括热度信息，以提高在较低级存储层处的数据可访问性的效率。 该方法可以包括向低层存储层发送提示。
