Architecture Analysis for storage devices

connected by means of a circular connection. This system is relatively simple to connect, the problem is that the number of enclosures will affect the system IO performance. In the old system, the backend is interconnected via FC bus, and in many existing systems, it is connected by SAS bus. This storage system has a separate control device, so it has a strong processing power, not only to achieve raid in a single disk device, volume management, but

In short, the key point is that the addresses at the last position of DRAM are separated by horizontal and vertical addresses. DRAM internal read/write usually traverses all columns of the row at the same time. This means that accessing the storage columns correctly mapped to a row on DRAM is much cheaper than traversing multiple rows to access the same amount of memory. T
