Problems solved by technology

[0003] The traditional cluster system takes computing nodes as the core, which has poor performance, complex structure, and poor scalability. Therefore, an architecture with switching as the core that is open, high-bandwidth, low-latency, high-reliable, and satisfying the unlimited scalability of the cluster is needed. Later Infiniband came into being

Embodiment Construction

[0050] The method of the present invention is described in detail below with reference to the accompanying drawings.

[0051] In the multi-control storage system of the embodiment of the present invention, the failure judgment of the controller depends on the heartbeat detection based on Ethernet and the message delivery detection based on Infiniband connection. In the multi-control storage system of N controllers, each controller needs Establish heartbeat and Infiniband connections with other N-1 controllers. Among them, the Infiniband connection is also used for the transmission of mirrored data and the transmission of MPIO multipath data.

[0052] The multi-protocol support module uses a unified management configuration interface to manage LUNs and host groups. A typical application topology is as follows figure 1 As shown, users can connect to any controller through an Ethernet switch to manage the system, and the controller software is responsible for providing users wi...

Abstract

The invention provides a method for designing a multi-control storage system. According to the multi-control storage system, the faults of controllers are judged according to heartbeat detection based on Ethernet and message delivery detection based on Infiniband connection; according to the multi-control storage system with the N controllers, each controller is required to establish heartbeat connection and Infiniband connection with other N-1 controllers; the Infiniband connection is also used for the transmission of mirrored data and the transmission of MPIO (Multipath Input / Output) data; a multi-protocol support module is arranged in the multi-control storage system; Luns (Logic Unit Numbers) and a host are managed through the utilization of uniform management configuration interfaces; users can be connected with any controller through Ethernet exchangers to manage the system; controller software is responsible for providing a uniform management view to the users; and application client sides are connected to a high-end disk array through Ethernet, FC (Fiber Channel) network and IB (Intelligent Building) network to pay a data read-and-write visit to exported LUNs, so that the design of the multi-control storage system is realized.

Description

technical field [0001] The invention relates to the field of computer systems and storage, and is a multi-control storage system and a transmission communication technology of a system control method, usually based on a disk storage system, aiming to provide highly available data storage services for key application scenarios. Background technique [0002] In the past storage system, each controller is directly connected to its own disk cabinet through its own back-end card, usually every two controllers are connected to a group of disk cabinets. In this system structure, when the controller fails, Its storage resources can only be taken over by controllers connected to the same group of disk cabinets, so the result is: if the controllers on the same group of disk cabinets cannot fail at the same time. With the emergence of SAS switches, multiple controllers can be connected to one or more independent external storage systems, thereby significantly expanding the function of ...
