Abstract:

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).

Key words: network storage, light weight communication protocol, VI(Virtual Interface)

摘要：

VIA(VirtualInterfaceArchitecture)是用户级集群通信工业标准。对VIA做了扩展,将其引入到网络存储领域,实现了内核级VIA,并且在Linux系统平台上进行了测试。和用户级VIA相比,内核级VIA全面提高了存储系统节点和服务器间通信性能。尤其是对于 512字节以下小数据包,延迟至少降低 30%。
