Progressive efforts have been evolving continuously for the betterment of the services of the Information Technology for Educational Management(ITEM). These services require data intensive and communication intensive applications. Due to the massive growth of information, situation becomes difficult to manage these services. Here the role of the Information and Communication Technology (ICT) in...

The Russian World Data Center for Solar-Terrestrial Physics and the World Data Center for Solid Earth Physics have been collecting, analyzing, archiving, and disseminating data and information on a wide range of geophysical disciplines since the International Geophysical Year 1957-1958. The centers provide free and convenient access for users to their large and permanently increasing volumes of...

This paper describes Mirador, a dynamic placement service implemented as part of an enterprise scale-out storage product. Mirador is able to encode multidimensional placement goals relating to the performance, failure response, and workload adaptation of the storage system. Using approaches from dynamic constraint satisfaction, Mirador migrates both data and client network connections in order ...

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 ...

Failures are usual rather exceptional in cloud computing environment. To access from the nearby site, the often used data should get replicated to multiple locations to compose the users to advance the system accessibility. A challenging task in cloud computing is to decide a sensible number and right location of replicas. At this point, we propose an adapted dynamic data replication approach t...

The energy consumption of High Performance Computing (HPC) systems, which are the key technology for many modern computation-intensive applications, is rapidly increasing in parallel with their performance improvements. This increase leads HPC data centers to focus on three major challenges: the reduction of overall environmental impacts, which is driven by policy makers; the reduction of opera...

There are no widely accepted design patterns for writing distributed, concurrent, fault-tolerant code. Each programmer develops her own techniques for writing this type of complex software. The use of a common pattern for fault-tolerant programming has the potential to produce correct code more quickly and increase shared understanding between developers. We describe rules, tasks, and pools, pa...

In the current decade of rapid expansion of ubiquitous data storage and cloud computing services, the demand for data centre services has seen an enormous increase which is resulting in a continuously rising pressure on the environment in terms of energy consumption and greenhouse gas (GHG) emissions. The recently started project, All4Green, explores potential ICT solutions for collaboration am...

Virtualization is a very popular solution to many problems in datacenter management. It offers increased utilization of existing system resources through effective consolidation, negating the need for more servers and additional rack space. Furthermore, it offers essential capabilities in terms of disaster recovery and potential savings on energy and maintenance costs. However, these benefits m...

Capacity of the distributed storage system (DSS) is often discussed in the context of tradeoff between storage overhead and repair bandwidth. This paper considers capacityachieving coding for the clustered form of distributed storage that reflects practical storage networks. The suggested coding scheme is shown to exactly regenerate the arbitrary failed node with minimum required bandwidth, i.e...
