Disk array is a long-standing technology on the server, it is widely used by most server OEMs to make reasonable use of space and performance in different array modes to match the cost-effective disk array. Among them, LSI Company's MegaRAID SAS products are widely used in various brands (except HP) x86 servers.Why is there a cache?Array Card core technology consists of three parts: 1, Data stripe, 2, data redundancy, 3, cache.
