Literature Review on Designing a High Performance Storage Server

In network continuous increase and speeds of CPU is fostering the new class development of applications which are new depending upon streaming, for example BBC iPlayer and YouTube. Unlike traditional applications of the client server which use transport mechanisms which have best-effort, QoS support is required by these new applications to deliver performance which is acceptable.

Demand misses are also supported by storage systems that happen when the data block is required by program to sustain execution of it.

 Misses of the demand should thus be satisfied promptly or else delays of the server execution will be experienced by applications. As a result it is required to balance the prefetching demands by making use of the clustering as well as the requirement to satisfy promptly misses of demand. To explore the storage servers design this has high performance, at Middlesex University Network Memory Server (NMS) is developed. 

The Network Memory Serve characteristics

With many key goals, NMS has designed. Firstly the NMS actions are considered as atomic by clients of it. These properties indicate that reason is presented to assume distribution which is Poisson for the rate of arrival and the service can assumed also to be exponential because the memory less system is presented with observe to transaction which is preformed previously.

Industrial and Management Project on IT Outsourcing Analytic Hierarchy Process

Introduction to Industrial and Management Project on IT Outsourcing Analytic Hierarchy Process:

This paper discussed about how to make Information Technology Outsourcing decision based on the Analytic Hierarchy Process. The developed two hierarchies are one for making a choice to outsource activities and the other to choose suitable outsourcing technique. 

The Decision making model: 

In the decision hierarchy, at first level, focus is there on an activity outsource. At second level, focus is there on criticality, stability and simplicity. At third level, a company may show any number of activities to choose from outsource as per requirement. The aspects of any activity are compared pair wise. The decision makers are responsible to answer question like how to develop current business position and what is the IT department’s strength. These two answers will helpful to decide whether outsourcing is required or not.  

In the decision hierarchy, at fourth level deciding the outsourcing methodology takes place.  Any activity will outsourced through several alternative contracts.  The contracts classified into four categories namely Insourcing, Value-added outsourcing, Short-term outsourcing and long-term outsourcing. Based on the advantages and disadvantages of a contract, company will decide that contract belongs to which category among the available 4 categories. Expert Choice or any other AHP software is used for responses analyzing. As the methodology for outsourcing, an alternative with the highest priority will get selected. 

An initial step in deciding the outsourcing methodology is to decide the business priorities. The overall focus has been fixed and this fixed focus ensures there is no loss in model generality.  In order to achieve the goal, the company has flexibility in deciding the criteria.  Decision makers assign values to the options available in the next level based on the goal’s view. IT Outsourcing helps to solve the current business problems, to improve the business and to transform\change the business. 

Conclusion: 

This paper proposed a decision making model ITO by using the Analytic Hierarchy Process (AHP).  The model developed was tested against an outsourcing decision made at India’s leading automobile company.  While taking decisions market trends need to consider.
