As the built-in scheduling strategy of Docker swarm cannot implement load balance of cluster very well and the utilization rate of cluster resource is not very high, a dynamic weighted scheduling algorithm was proposed. The weight coefficient was set on the resource, and the parameter bias was introduced to dynamically adjust the resource weight for different services. According to the actual resource utilization of each node, the node weight was calculated to reflect node load, and was used for scheduling. Compared with the original Docker scheduling strategy and the weighted scheduling strategy without parameter adjustment, the proposed algorithm makes all the resource utilization of each node in the cluster more balanced. At the same time, the proposed algorithm can achieve faster service running speed under the condition of high cluster load.

VIA(Virtual Interface Architecture) has been developed to standardize user-level network communication protocol. The kernel VIA was implemented and used in network storage. The test on Linux platform shows that the kernel-level VIA can improve all aspects of the I/O path between the storage nodes and the servers compared to the user-level VIA, especially can decrease the latency at least 30% for small-sized requests(<512B).

A remote real-time management system for FC-RAID 3000 based on embedded Web server GoAhead was designed and implemented. The system communicated with remote user through GoAhead, which accepted the user’s requests and responded with corresponding Web pages stored in the minimal file system. When the user logged in, the remote management module would authenticates the user’s authority; and when the user sent configuring and monitoring command, the remote management module would parse the command and execute it by calling the functions provided by RAID controlling module. The system can efficiently improve the management performance of FC-RAID 3000.
