Store area Network utilizando alternativas de software libre

Abstract

Abstract: Today the need to store and share information in business environments has become a basic element of information systems. Most companies and institutions in the local environment use shared folders on different computers. Network storage, in spite of its importance and functionality, is a technology little used in our environment due to the lack of knowledge or the cost involved in contracting solutions of recognized brands. However, there are free software alternatives that provide a level of reliability and flexibility at a very low cost and also allow hardware independence, which allows the use of less expensive equipment or adaptations of equipment already available. This work was developed to evaluate the alternative of using free software to create a Store Area Network SAN, specifically the FreeNAS operating system based on the FreeBSD operating system, which provides network storage services. The implementation of iSCSI units was carried out in order to improve tolerance to storage media failures, which represent the main cause of data loss. The results obtained during the tests showed that it is possible to restore services using this system in case of hardware failure in the storage server, as well as failure in the client equipment.
