Abstract
Data storage plays an essential role in today's fast-growing data-intensive network services. iSCSI is one of the most recent standards that allow SCSI protocols to be carried out over IP networks. However, the disparities between SCSI and IP prevent fast and efficient deployment of SAN (storage area network) over IP. This paper introduces STICS (SCSI-To-IP cache storage), a novel storage architecture that couples reliable and high-speed data caching with low-overhead conversion between SCSI and IP protocols. Through the efficient caching algorithm and localization of certain unnecessary protocol overheads, STICS significantly improves performance over current iSCSI system. Furthermore, STICS can be used as a basic plug-and-play building block for data storage over IP. We have implemented software STICS prototype on Linux operating system. Numerical results using popular PostMark benchmark program and EMC's trace have shown dramatic performance gain over the current iSCSI implementation.
在数据密集型网络业务快速发展的今天,数据存储扮演着至关重要的角色。iSCSI是允许在IP网络上执行SCSI协议的最新标准之一。然而,SCSI和IP之间的差异阻碍了在IP上快速有效地部署SAN(存储区域网络)。本文介绍了SCSI- to -IP缓存存储,这是一种新型的存储体系结构,它将可靠的高速数据缓存与SCSI和IP协议之间的低开销转换结合在一起。通过高效的缓存算法和某些不必要的协议开销的本地化,与当前的iSCSI系统相比,STICS显着提高了性能。此外,可以将STICS用作通过IP进行数据存储的基本即插即用构建块。我们在Linux操作系统上实现了软件的原型。使用流行的邮戳基准程序和EMC跟踪的数值结果显示,与当前的iSCSI实现相比,性能有了显着的提高。
