Large-scale storage systems may service millions of clients. Effectively identifying and authenticating these clients can not only prevent illegal accesses but also eliminate unnecessary redundancies of access control. However, existing security solutions have largely ignored the identification and authentication issues or separately consider them from access control mechanisms. As a result, these...
This paper presents the implementation and performance evaluation of a real, secure object-based storage system compliant to the T10 OSD standard. In contrast to previous work, our system implements the entire three security methods of the OSD security protocol defined in the standard, namely CAPKEY, CMDRSP and ALLDATA, and an Oakley-based authentication protocol by which the Metadata Server (MDS)...
In this paper, we present the design of a domain-based storage management framework for the wide area network (WAN) toward catering for the large-scale and heterogeneous storage environment. In our design, we include the framework architecture, the registration mechanism based on the use of session initiation protocol (SIP), and the storage management initiative specifications (SMI-S) based storage...
Grid storage service aims to support mass storage space on the grid so that application servers can provide data for end users without their own storage devices. This paper gives a brief introduction of Grid storage service. Based on OGSA, we discuss its authorization, security and some research issues
With the development of network storage technology, object-based storage (OBS), as the next wave of storage technology and devices, provides the advantages of both file storage and block storage. However, the performance of such network storage hinges on knowing the I/O traffic patterns and optimizing the network for such patterns. Recently the notion of self-similarity has been applied to I/O workload,...
Most of traditional load balancing strategies are based on servers or applications architecture. Storage subsystem, as the back tier, provides file or block interface to server or application tier, is often ignored when the bottleneck of service is studied. Our load balancing strategy is based on storage object, which provides object interface for the up tier. We concentrate on storage objects with...
It obviously gets limited advantage in massive storage system that all the management works are done by the servers, such as file server and metadata server of traditional storage area network (SAN). Moreover, storage device with deficient intelligence leads to lack of supporting local policy and does not scale well in performance and functionality when the number of storage device is added. At the...
