iSCSI is a network storage technology designed to provide an economical solution over a TCP/IP Network. This paper presents a new iSCSI design with multiple TCP/IP connections. The prototype is developed and experiments are conducted for performance evaluation on Gigabit Ethernet (GE). Test results show that the new iSCSI design improves performance 20%~60%(More)
In large distributed Object-based Storage Systems, the performance, availability and scalability of the Metadata Server (MDS) cluster are critical. Traditional MDS cluster suffers from frequent metadata access and metadata movement within the cluster. In this paper, we present a new method called Hashing Partition (HAP) for MDS cluster design to avoid these(More)
Modeling and simulation is an effective way to design and evaluate the performance of a network storage system. OSDsim is designed and developed for simulation of an Object-based Storage Device (OSD) system. An OSD File System (OSDFS) has been designed and developed for OSDsim. It can provide high throughput for big object requests and also maintain high(More)
—In datacenter network (DCN) research, one key challenge is to reproduce the relative performances of different scalable DCN architectures in an unbiased and transparent way. Adequately addressing this challenge will support the validation of performance studies, and this is fundamental to building a strong research foundation and making wise datacenter(More)
Today's Data Centers deploy load balancers to balance the traffic load across multiple servers. Commercial load balancers are highly specialized machines that are located at the front end of a Data Center. When a client request arrives at the Data Center, the load balancer would determine the server to service this client's request. It routes the request to(More)
