Our clients typically migrate to SAN from systems that provide less utility. For example, our client needed an upgrade from a file-level NAS system. The client used local file sharing and the NAS provided access to users in different departments of the business, such as finance, HR, marketing, etc. As their operations grew larger, the IT department realized the need for a higher end storage system like a block-level SAN server.
The SAN server would provide them various practical benefits and enhanced utility. The SAN would provide benefits such as better reliability, availability, support, features, and speed. To be more specific, the SAN server will provide better redundancy. SAN would allow them to have a cluster of VMware servers. This means they would be up and running in minutes, or not in no time at all, in case one of their VMware server malfunctions. Moreover, the equipment a SAN server uses are enterprise grade and therefore have a much lower failure rate and give much greater speeds.
