High-end storage PCIE interchanger and management module thereof

Abstract

The invention discloses a high-end storage PCIE interchanger and a management module thereof. The management module comprises a substrate and a CPU board card used for controlling and monitoring the PCIE interchanger, the CPU board card is connected with the substrate in a detachable manner, the substrate is provided with an external communication interface providing backboard PCIE signals, and the substrate is also provided with an external output network interface and an external output serial port for the CPU board card. When placement and routing are carried out to the management module of the high-end storage PCIE interchanger, placement and routing are carried out to the CPU board card and the substrate, the CPU board card and the substrate are modularized in design, and placement and routing are simpler. When the high-end storage PCIE interchanger is upgraded later, only the CPU board card needs to be upgraded again, placement and routing are carried out to the CPU board card again, then the upgraded new CPU board card is connected to the substrate, placement and routing of communication interfaces, output network interfaces and serial ports are avoided, the placement and routing difficulty level is further reduced, and the research and development cost is reduced at the same time.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a high-end storage PCIE switch and a management module thereof. Background technique [0002] With the development of PCIE technology, it has become the development trend of communication technology to interconnect multiple communication devices between boards for data forwarding through the PCIE protocol. At this time, it must be applied to PCIE switches. Among them, the so-called PCIE technology refers to external Set up component interconnection standard extension technology. [0003] According to Moore's Law, the computing speed of the CPU increases exponentially on a regular basis and has reached the nanoscale process. However, the data reading speed of the mechanical disk has a limited increase, from 72,000 rpm to 100,000 rpm to 150,000 rpm. The response speed only reaches the millisecond level, which is several orders of magnitude lower than the CPU's computing spee...

Problems solved by technology

However, the management module of the PCIE switch for high-end storage is designed as an independent board, which integrates the control function and data transmission function of the switch, and the wiring is complicated, which makes the layout and wiring of the board very difficult. , and because the management module will be upgraded over time, it is necessary to redesign the board of the management module, the control function unit, the data transmission function unit and many wirings, making the research and development cost high
