摘　　要：全闪存NAS在云资源池中为部分上层业务系统提供高性能文件系统访问,并通过IP地址漂移确保业务访问连续性。当全闪存NAS采用3层IP方式接入多台核心交换机,且出现核心交换机故障时,IP地址无法漂移,导致业务访问中断。为了解决各种故障场景下全闪存NAS的高可用问题,本文提出在全闪存NAS和核心交换机间增加2层交换机及在全闪存NAS和核心交换机间部署边界网关协议(BGP)路由协议两种技术方案,解决了IP地址漂移问题,确保了全闪存NAS的高可用。同时对两种技术方案进行对比分析,提出高可用和低成本的方案建议。All-fl ash network attached storage provides high-performance fi le system access for some upper-layer business systems in the cloud resource pool and ensures business access continuity through IP address drift.When allflash network attached storage is connected to multiple core switches based on IP and a core switch fails,the IP address cannot drift,resulting in business access interruption.In order to solve the high availability problem of all-fl ash network attached storage in various failure scenarios,this paper proposes two technical solutions:adding layer 2 switches between all-fl ash network attached storage and core switches and deploying the BGP routing protocol between all-fl ash network attached storage and core switches.These solutions solve the IP address drift problem and ensure the high availability of all-fl ash network attached storage.At the same time,a comparative analysis of the two technical solutions is carried out,and a scheme suggestion with high availability and low cost is put forward.
