Designing a storage area network (SAN) fabric requires devising a set of hubs, switches and links to connect hosts to their storage devices. The network must be capable of simultaneously meeting specified data flow requirements between multiple host-device pairs, and it must do so cost-effectively, since large-scale SAN fabrics can cost millions of dollars. Given that the number of data flows c...

Storage Area Networks (SANs) are an emerging data communications platjorm which interconnects servers and storage devices (such as disks, disk arrays, and tape drives) to create a pool of storage that users can access directly. This networking approach reports benefits such as computer clustering, topologicaljlexibility, fault tolerance, high availability, and remote management. In order to eva...

Storage-area networks are a popular and efficient way of building large storage systems both in an enterprise environment and for multi-domain storage service providers. In both environments the network and the storage has to be configured to ensure that the data is maintained securely and can be delivered efficiently. In this paper, we describe a model of mandatory security for SAN services th...

Storage Area Networks, with their ability to offer high data availability, reliability and scalability, are a promising solution for the large scale storage needs of many enterprises. As with any distributed storage system, a major design challenge for a Storage Area Network (SAN) is to provide data integrity and confidentiality. In this paper, we propose a solution which addresses these core s...

Currently, there are several wireless networks deployed around the world. Examples include cellular networks, metropolitan area networks, wireless local area networks, and personal area networks. The combination of all these networks is usually called the beyond 3G (B3G) wireless networks. New state-of-the-art mobile terminals will allow users to freely move and to switch connections among diff...

Security is the most important aspect considered while using the wireless local area networks. Various techniques have been used in the past to increase the security of WLAN’s while simultaneously making the authentication process faster. The paper presents the review of various such techniques that have been used in the past for the enhancement of the security and achieving fast authentication...

—An explosive increment of data and a variety of data analysis make it indispensable to lower power and cooling costs of cloud datacenters. To address this issue, we investigate the thermal impact of I/O access patterns on data storage systems. Firstly, we conduct some preliminary experiments to study the thermal behavior of a data storage node. The experimental results show that disks have ig...

Wireless Local area networks (wLANs), particularly from standards 802.1b/g, have become extremely widespread in a very short time, in society in general as well as at an industrial level. One of the limitations of this technology is its coverage. The family of new standards, such as 802.16, allows us to overcome these limitations, enabling then their use as Metropolitan Area Networks (MAN), as ...

In recent years, the scale of datacenters has become larger due to the explosive increase in the amount of digital data. As a result, the growth of energy consumption is an important factor in the management cost of datacenters. Storing and processing such large volumes of data by database applications are the core technologies in this Big Data era. However, storage accounts for a significant p...

Nowadays, the explosive growth of digital contents continues to rise the demand for new storage and network capacities, along with an increasing need for more cost effective use of storage and network bandwidth for data transfer. As such, the use of remote storage systems is gaining an expanding interest, namely the cloud storage based services, since it provides cost efficient architectures. T...
