Virtualization
What is Virtualization?
Virtualization is the abstraction of computer resources, and it hides the physical characteristics of computing resources from their users, be they applications, or end users. This includes making a single physical resource (such as a server, an operating system, an application, or storage device) appear to function as multiple virtual resources; it can also include making multiple physical resources (such as storage devices or servers) appear as a single virtual resource.
Why is it important?
Virtualization is being increasingly used by IT departments for server consolidation and testing purposes. Virtual servers are used to reduce operational costs and to improve system efficiency. The growth in virtual servers has created challenges for IT departments regarding high availability and data protection. It is not enough to protect physical servers but also virtual servers as they contain business critical data and information. Virtual servers offer the flexibility, but at the same time if a single physical server containing multiple virtual servers fails, then the impact of data loss is enormous.
The Sonasoft Solution
Sonasoft provides a high-availability solution, protecting data that reside on virtual servers. SonaSafe application supports many interesting disaster recovery scenarios. Customers can have multiple physical servers at the primary location and at the offsite disaster recovery location, they can have one physical server with multiple virtual servers. Also, multiple virtual servers from the primary site can be easily backed up and replicated to the disaster recovery site.
In the case of SonaSafe, both on physical and virtual servers, the appropriate agents are installed and these agents have a very small footprint. Because of the limited footprint, the impact on these servers is minimal from a performance perspective. With other replication solutions, one has to install the entire application on the virtual servers and this will take a huge toll on performance.
