    Abstract: A persistence management system performs, at a server, operations associated with a number of applications. At the server, a persistence manager can intercept a file system call from one of the applications, wherein the file system call specifies a file located on a remote persistent storage device separate from the server. The persistence manager can determine that data belonging to the file requested by the file system call is stored on a local persistent storage device at the server, retrieve the data from the local persistent storage, and respond to the file system call from the application with the data.

    Abstract: A method and system for optimized read access to shared data via monitoring of mirroring operations are described. A data storage system performs operations that include one controller in a dual-controller host storage appliance in an asymmetric active/active configuration receiving a request from the host for data on a logical unit number owned by the partner controller. The receiving controller, which has a mirror cache of the partner controller's memory for failure recovery, accesses the mirror cache using a data structure that was populated during previous mirror operations. If the data is found in the mirror cache, it is read from the cache and returned to the requesting host without having to contact the partner controller for the data.

    Abstract translation: 描述了通过监视镜像操作优化对共享数据的读取访问的方法和系统。 数据存储系统执行操作，该操作在非对称主动/主动配置中的双控制器主机存储设备中包括一个控制器，从主机接收对由对方控制器拥有的逻辑单元号的数据的请求。 具有用于故障恢复的伙伴控制器的存储器的镜像缓存的接收控制器使用在先前镜像操作期间填充的数据结构访问镜像缓存。 如果在镜像缓存中找到数据，则从高速缓存中读取数据并返回给请求主机，而不必与数据的伙伴控制器联系。
