[0020] 1: Implementation based on device mapper mechanism
[0021] figure 1 It is the overall structure diagram of the caching mechanism.
[0022] Target type is a modular plugin interface that allows customization. The mechanism of SCS (SSD cache SSD) is to use this interface to define a new target type, define the cache area and data area as two new target devices, design the mapping rules of the cache, and logically combine them into a new block equipment. Therefore, through the mapping table, the data from the upper layer can be sent to different devices according to the rules, thereby realizing data redirection. The specific steps are:
[0023] 1. The write request of the upper layer is firstly detected by the I / O sequence, and the random I / O is cached in the RAMbuffer of the small block in the memory;
[0024] 2. After the RAM buffer is full, write them sequentially into the SSD buffer in the form of a sequential log;
[0025] 3. When the buffer is idle or when the...
