iSCSI中多个TCP连接的性能评估

Performance Evaluation of Multiple TCP connections in iSCSI

Bhargava Kumar K, Ganesh M. Narayan, K. Gopinath

摘要:

扩展数据存储是企业系统中的一个重要问题,存储区域网络(SAN)被部署为扩展企业存储的一种手段。基于光纤通道的SAN在过去十年中得到了广泛的应用,而iSCSI由于其降低的成本和统一的基础架构,正迅速成为一个重要的竞争者。这项工作将检查iSCSI与多个TCP连接的性能。多个TCP连接通常用于实现更高的带宽,但带宽分配方式可能不公平。我们提出了一种机制,以共享拥塞信息跨多个流在“公平TCP”,以提高性能。我们的研究结果表明,Fair-TCP显着提高了I/O密集型工作负载的性能。

英文摘要:

Scaling data storage is a significant concern in enterprise systems and Storage Area Networks (SANs) are deployed as a means to scale enterprise storage. SANs based on Fibre Channel have been used extensively in the last decade while iSCSI is fast becoming a serious contender due to its reduced costs and unified infrastructure. This work examines the performance of iSCSI with multiple TCP connections. Multiple TCP connections are often used to realize higher bandwidth but there may be no fairness in how bandwidth is distributed. We propose a mechanism to share congestion information across multiple flows in ``Fair-TCP'' for improved performance. Our results show that Fair-TCP significantly improves the performance for I/O intensive workloads.
