This chapter along with the additional resources given in the references will support the usage of SAN technologies in enterprises. The first half of this chapter develops the new framework needed. The second half of this chapter details the capabilities of fabric topology. To lay the groundwork for a networked storage system, it is important to understand these concepts in order to best plan the first steps of building a new secure and open enterprise storage infrastructure.

To protect data in cloud storage, fault tolerance and efficient recovery become very important. Recent studies have developed numerous solutions based on erasure code techniques to solve this problem using functional repairs. However, there are two limitations to address. The first one is consistency since the Encoding Matrix (EM) is different among clouds. The other one is repairing bandwidth, which is a concern for most of us. We addressed these two problems from both theoretical and practical perspectives. We developed BMCloud, a new low repair bandwidth, low maintenance cost cloud storage system, which aims to reduce repair bandwidth and maintenance cost. The system employs both functional repair and exact repair while it inherits advantages from the both. We propose the JUDGE_STYLE algorithm, which can judge whether the system should adopt exact repair or functional repair. We implemented a networked storage system prototype and demonstrated our findings. Compared with existing solutions, BMCloud can be used in engineering to save repair bandwidth and degrade maintenance significantly.

Regenerating codes are based on the concept of the network coding. Compared with the traditional codes used for fault-tolerant, it has advantages for its low redundancy and high efficiency. We present DSRC, a distributed networked storage system realizing a traditional regenerating code and a secure regenerating code in real network settings. We deploy and evaluate our DSRC prototype in a real network setting. We also use DSRC to experiment the empirical performance of storage schemes with the secure regenerating code. The evaluate shows that the secure regenerating code can achieve the security of the fault-tolerant process with a little higher throughput.

A color coded digital image processing is accomplished by using JEM100CX TEM SCAN and ORTEC’s LSI-11 computer based multi-channel analyzer (EEDS-II-System III) for image analysis and display. Color coding of the recorded image enables enhanced visualization of the image using mathematical techniques such as compression, gray scale expansion, gamma-processing, filtering, etc., without subjecting the sample to further electron beam irradiation once images have been stored in the memory.The powerful combination between a scanning electron microscope and computer is starting to be widely used 1) - 4) for the purpose of image processing and particle analysis. Especially, in scanning electron microscopy it is possible to get all information resulting from the interactions between the electron beam and specimen materials, by using different detectors for signals such as secondary electron, backscattered electrons, elastic scattered electrons, inelastic scattered electrons, un-scattered electrons, X-rays, etc., each of which contains specific information arising from their physical origin, study of a wide range of effects becomes possible.
