    Abstract: A method, computer program product, and computing system for associating a heatmap file with a multi-portion data file located on a data array. The heatmap file is configured to monitor the usage of each portion of the multi-portion data file. At least one portion of the multi-portion data file is used via a virtual machine executed on a first physical machine. The heatmap file is updated to reflect the usage of the at least one portion of the multi-portion data file.

    Abstract: A method, computer program product, and computing system for processing, on a host, a read request for a portion of a data file stored on a backend storage system. The portion of the data file is obtained from the backend storage system. The portion of the data file is divided into a plurality of file chunks based, at least in part, upon a file type. Each of the plurality of file chunks is compared to other file chunks stored within a frontend cache system associated with the host to identify unique file chunks within the plurality of file chunks. The unique file chunks are stored within the frontend cache system.

    Abstract translation: 一种用于在主机上处理存储在后端存储系统上的数据文件的一部分的读取请求的方法，计算机程序产品和计算系统。 从后端存储系统获取数据文件的一部分。 至少部分地，根据文件类型将数据文件的该部分分成多个文件块。 将多个文件块中的每一个与存储在与主机相关联的前端缓存系统中的其他文件块进行比较，以识别多个文件块中的唯一文件块。 唯一的文件块存储在前端缓存系统中。

    Abstract: A method, computer program product, and computing system for defining a portion of a frontend cache system for use as a data array cache portion. One or more cache slots included within a backend cache system are identified that are going to be overwritten with hot cache data and are currently filled with cold cache data. The cold cache data included within the one or more cache slots included within the backend cache system is written to one or more cache slots included within the data array cache portion.

    Abstract: A processing device in one embodiment comprises a processor coupled to a memory and is configured to intercept a storage communication directed over a storage channel between a potentially infected machine and an associated storage system, and to determine if the intercepted storage communication is from a security agent deployed on the potentially infected machine. If the intercepted storage communication is from the security agent, at least a portion of the communication is provided to a security system. If the intercepted storage communication is not from the security agent, the communication is forwarded to the storage system. Accordingly, the security agent is configured to communicate with the security system using storage communications sent over the storage channel in a manner that avoids detection of the security agent by malware that may be installed on the machine and configured to monitor network communications.
