在云存储技术中,资源复用和共享是一把双刃剑,在为用户降低开销的同时,也导致了应用之间的相互干扰和竞争,特别是在资源需求量超出存储系统能力时,无法提供令人满意的服务质量。提出一种自适应的任务调度技术,解决了前后端任务的资源平衡问题。还提出一种多级热度的缓存替换技术,解决了前端任务间的资源平衡问题。在中兴分布式块存储系统中将上述两项技术进行了工程实现和商用测试,上述优化方案满足了用户对分布式块存储服务质量的期望。
In cloud storage technology
resource reuse and sharing is a double-edged sword.While it reducing the overhead for customers
it leads to a situation that the different applications will compete for hardware resources
especially when resource requirement exceeded storage system capability.As a consequence the cloud storage system is unable to provide satisfactory quality of service.An adaptive scheduling technology was proposed
solving the resource balance problem between front tasks and back tasks.A multilevel popularity cache replacement technology was also proposed
solving the resource balance problems between the front tasks themselves.These technology was implemented and tested on the ZTE distributed block storage system.The proposed technology satisfies the expectations of the quality of service from the users.
