可重复使用飞行器地面系统超融合设计及应用

Design and Application of Hyper-Converged Ground Systemfor Reusable Spacecraft

摘要:

针对可重复使用飞行器地面系统应用要求和现行方案存在的问题，改变各分系统独立设计思路，将地面系统作为一个整体，将其广义的各类计算机抽取出来，进行超融合设计，通过软件定义硬件和服务器虚拟化、存储虚拟化、网络虚拟化、显控桌面化，可实现根据各分系统任务需要，进行计算机资源的灵活分配和动态调度，以虚拟机、云桌面的形式供各分系统使用，简化了地面系统的配置和部署，实现了地面系统的通用化、简易化、便捷化、可配置化、高可用性。与各分系统独立设计方案应用对比和性能测试表明，地面系统超融合设计减少了IT设施32%，缩短了部署时间52%，降低了运维复杂度60%，可用性达到了99.9%以上，服务延迟率低于44%，并可实现灵活配置，能适应不同型号的可重复使用飞行器应用。

Abstract:

In response to the requirements for the application of reusable spacecraft ground system and the existing problems in the actual scheme, the ground system is taken as a whole and its generalized various computers are extracted to design a hyper-converged scheme which replaces the independent design concept of each subsystem. Through software definition hardware and server virtualization, storage virtualization, network virtualization, display and operation desktop, computer resources can be distributed flexibly and adjusted dynamically to adapt for the needs of various subsystem tasks. Provided to each subsystems in the form of virtual machines and cloud desktops, the ground system configuration and deployment is simplified, and also generalized, convenient, configurable, highly available. The application comparison with independent design scheme for each subsystem and performance test show that the ground system hyper-converged scheme reducing IT facilities by 32%, shortening deployment time 52%, reducing the complexity of operation and maintenance by 60%, with availability achieving over 99.9%, service delay rate lower than 44% and enabling flexible configuration, which makes it adapt to application of different kinds of reusable spacecrafts.
