In the world of storage solutions, management remains a huge gap in the administration of storage subsystems. It's a challenge to manage storage at any level, because data center hardware growth is typically heterogeneous.
Although many strategies exist to help manage the terabytes, the proprietary solutions available today only rarely interoperate. "To date," says Jon Toigo, an expert on storage management, "the industry has shown only limited interest in making products work together in any sort of coherent management scheme. Until some of the incompatibilities in array controllers and fabric switches are fixed, the success of a storage virtualization strategy in delivering these values may be limited. As with most technologies, try it before you buy it."
Solutions for these incompatible systems range from simple backup, to archives and replication, to single-instancing. But one of the tools that has seen growth is storage virtualization. In fact, more and more products such as SANmelody from DataCore Software Corp. ...
