There are a number of pervasive problems with storage systems in the marketplace today. Typically, data is entered from the external interface, and the storage engine handles data processing. Each storage engine has its own characteristics that can be used for data applications, compression, encryption, and mapping. While the storage engine processes the data, it also responds and sends an answer to a high-level application. To achieve this, all storage systems use some kind of write cache to respond as quickly as possible, enabling applications to perform their respective tasks. In addition, the Data Processing section produces a lot of metadata. For each I/O into the system, ...
