Over the past two years a combination of circumstances has fueled intense efforts to rethink the integration of IP networking and mass storage. Chief among these facts are the universal acceptance of Internet technologies for network infrastructure, the relentless acceleration of the Ethernet substrate, and the ongoing, exponential rise in the amount of data that must be moved and managed. Take...

The working principle of scanning acoustic microscope (SAM) is introduced, and the acoustic transmission action is analyzed according to the geometrical and structural characteristics of explosive/Aluminum-alloy binding. The adhesive status of the interface in some typical parts of the binding is detected by SAM and 30MHz ultrasonic focal field lens. The results show that the interfaces between...

In this paper, we study the transport of air masses to San Pietro Capofiume (SPC) in Po Valley, Italy, by means of back trajectories analysis. Our main aim is to investigate whether air masses originate over different regions on nucleation event days and on nonevent days, during three years when nucleation events have been continuously recorded at SPC. The results indicate that nucleation event...

The point availability is the probability that a system is available at time t. As grids need a lot of resources to be really operational, the evolution of their availability with time or depending on a maintenance process is a hot topic. But as grids contain a lot of resources, it is quite difficult to model and solve this problem. Here we advocate a component based description which is associ...

the present study aimed at estimating the amount of carbon storage and its relationship with other physical and chemical soil properties in four land-use systems including intact, protected, exploited and garden-uses areas in the northern zagros region in west azarbaijan province, iran. thirty sample plots were identified and within each plot, soil samples were taken in each land use and each s...

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 multi-domain sto...

OceanStore is a utility infrastructure designed to span the globe and provide continuous access to persistent information. Since this infrastructure is comprised of untrusted servers, data is protected through redundancy and cryptographic techniques. To improve performance, data is allowed to be cached anywhere, anytime. Finally, monitoring of usage patterns allows adaptation to regional outage...

This paper discusses some fundamental aspects of Distributed File Systems (DFS) for Storage Area Networks (SANs). Many desirable features make a SAN DFS attractive to a production environment that processes huge volumes of bulk data and requires high bandwidth. Throughout the discussion, the traditional server-attached storage model is compared against the distributed network-attached storage m...

This paper describes the motivation, architecture and implementation of iSAN, an “intelligent” storage area network. The main contributions of this work are: (1) how to architect an intelligent SAN that understands the storageconsumers to serve them better; (2) how to realise this abstract architecture using existing technologies; and (3) to demonstrate the benefits that would accrue from such ...
