Embodiment Construction

[0026] The present invention provides a load balancing method and device using dual blade servers to solve the problem of how to achieve load balancing in some ATCA blade server systems that do not provide load balancing node boards. Specific embodiments are described in detail below, but not as a limitation to the present invention.

[0027] The main technical idea of ​​the present invention is that the mid-blade server in the ATCA server system is transformed into a double-blade server, which works in a load sharing mode. An IOP (Input and Output Processor) module is inserted into each blade server board, and the IOP module provides a unified single or multiple VIP (Virtual IP, virtual IP) addresses externally through the virtual IP technology. All external data is split through the IOP module and distributed to dual blade servers for processing.

[0028] Among them, both blade servers provide PE (PCI Express, High-speed Serial Peripheral Device Interconnect Bus Specificati...

Abstract

The invention discloses a load balancing method and device using dual blade servers. The method includes: setting an input and output processing IOP module inside each blade server in an ATCA blade server system; PE bridges of each blade server and IOP The modules are connected, and the IOP module writes the input and output IO data into the memory through the PE bridge for processing by the central processing unit CPU of the blade server, and reads the data processed by the CPU from the memory of the blade server for transmission to the backplane through the IO device ;Two adjacent blade servers in the system are connected to each other's PE bridge through the backplane through the NT ports of their respective PE bridges. The two blade servers share resources with each other through the above connection, and the two blade server IOP modules Connected through the backplane, the IOP module provides a unified virtual IP address for the blade server. The invention improves the working efficiency of the blade server.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a load balancing method and device in the application of ATCA (Advanced Telecom Computing Architecture, Advanced Communication Computing Architecture) blade server system. Background technique [0002] The ATCA (Advanced Telecom Computing Architecture, Advanced Communication Computing Architecture) blade server system is a frame-type high-performance blade server system constructed using ATCA specifications, consisting of a switch node board and a high-performance blade node board. The ATCA blade server system can provide up to 12 blades per frame, which can provide good system processing performance. The system described here includes: a blade server and an ATCA frame. [0003] However, for some ATCA blade server systems that do not provide a load balancing node board, how to more reasonably use the ATCA blade server system to achieve the purpose of load balancing has become a...
