With the evolution of cloud computing technology, companies like Amazon, Microsoft, Google, Softlayer, and Rackspace have started providing Infrastructure as a Service, Software as a Service, and Platform as a Service offering to their customers. For these companies, providing a high degree of availability is as important as providing an overall great hosting service. Disaster is always being unpredictable, the destruction caused by it is always worse than expected. Sometimes it ends up with the loose of information, data and records. Disaster can also make services inaccessible for very long time if disaster recovery was not planned properly. This paper focuses on protecting a vSphere virtual datacenter using Site Recovery Manager (SRM). A study says 23% of companies close within one year after the disaster struck. This paper also discusses on how SRM can be a cost effective disaster recovery solution compared to all the recovery solutions available. It will also cover Recovery Point Objective and Recovery Time Objective. The SRM works on two different replication methodologies that is vSphere replication and Array based replications. These technologies used by Site Recovery Manager to protect Tier-1, 2, and 3 applications. The recent study explains that Traditional DR solutions often fail to meet business requirements because they are too expensive, complex and unreliable. Organizations using Site Recovery Manager ensure highly predictable RTOs at a much lower cost and level of complexity. Lower cost for DR. Site Recovery Manager can reduce the operating overhead by 50% by replacing complex manual run books with simple, automated recovery plans that can be tested without disruption. For organizations with an RPO of 15 minutes or higher, vSphere Replication can eliminate up to $10,000 per TB of protected data with storage-based technologies. The combined solution can save over USD $1,100 per protected virtual machine per year. These calculations were validated by a third-party global research firm. Integration with Virtual SAN reduces the DR footprint through hyper-converged, software-defined storage that runs on any standard x86 platform. Virtual SAN can decrease the total cost of ownership for recovery storage by 50 percent.


The successful completion of this paper could not have been possible without the guidance of my beloved professors, Dr. Dennis Guster and Dr. Susantha Herath. I also would like to thank Professor Sneh Kalia for being part of the committee and finding the time to read my thesis.

I also would like to thank my mother K. Ganga Bhavani, father K V S S V Prasad and friends who were with me supporting me the entire way with whatever was needed.
