Abstract: A system and method proxies data access commands across a cluster interconnect between storage appliances and a cluster using a file-level protocol. Each storage appliance activates two ports per data access, a local port for data access requests directed to clients of the storage appliance and a proxy port for data access requests directed to the partner storage appliance. Clients utilizing multi-pathing software may send data access requests to either the local port of the storage appliance or the proxy port of the storage appliance. The system and method improves high availability, especially during a loss of connectivity due to non-storage appliance hardware failure.

Abstract translation: 系统和方法通过存储设备和使用文件级协议的集群之间的集群互连来代理数据访问命令。 每个存储设备每个数据访问激活两个端口，用于指向存储设备的客户机的数据访问请求的本地端口和用于指向对方存储设备的数据访问请求的代理端口。 使用多路径软件的客户端可以将数据访问请求发送到存储设备的本地端口或存储设备的代理端口。 系统和方法提高了高可用性，特别是在由于非存储设备硬件故障而导致连接丢失的情况下。
