Online Remote Data Backup for iSCSI-Based Storage Systems
نویسندگان
چکیده
Data reliability is critical to many data sensitive applications, especially to the emerging storage over the network. In this paper, we have proposed a method to perform remote online data backup to improve reliability for iSCSI based networked storage systems. The basic idea is to apply the traditional RAID technology to iSCSI environment. Our first technique is to improve the reliability by mirroring data among several iSCSI targets, and second is to improve the reliability and performance by striping data and rotating parity over several iSCSI targets. Extensive measurement results using Iozone have shown that both techniques can provide comparable performance while improving reliability.

Performance Improvement of iSCSI Remote Storage Access through Optimization of Multiple Layers
iSCSI is one of the most popular protocols among the storage area network (SAN) working on an IP network. iSCSI is a standard to encapsulate a SCSI command into a TCP/IP packet, thus we can make an access to a storage system with commoditized IP devices only. In this paper, iSCSI sequential write access for a remote backup system is focused. It is well known that iSCSI experiences performance d...

In Ubiquitous computing environment the mobile devices such as PDAs necessarily connect to remote storage servers. We present an iSCSI caching system that localizes iSCSI target to overcome the shortcomings of iSCSI performance dropping sharply as the latency increases. 1 Motivation Mobile devices such as PDAs are evolving to be incorporated into Ubiquitous computing environment. Due to lightly...
متن کاملTLFS: High Performance Tape Library File System for Data Backup and Archive
A tape library is seldom considered as a viable place for constructing a file system for a sequential write/read device. Storage virtualization technology has become a buzzword in technology circles lately, in this paper we propose a tape library file system, called TLFS. The purpose of TLFS is to maintain a consistent view of mass storage so that the user can effectively manage it. Like disk f...

iSCSI is becoming an important protocol to enable remote storage access through the ubiquitous TCP/IP network. Due to the significant shift in its transport mechanism, iSCSI-based storage system may possess different performance characteristics from the traditional storage system. Simulation offers a flexible way to study the iSCSI-based storage system. In this paper, we present a simulation wo...

iSCSI and FCIP, the IP storage protocols are widely used to interconnect geographically distributed storage devices and access remote disk volumes over IP networks. The main aim of this work is to examine the performance features of iSCSI protocol by comparing them to features of FCIP protocol. The additional, more general aim of this work related to the idea of building low-cost, large-scale a...
