Seanodes released the results of a third-party survey of IT professionals that shows that the transition from direct attached storage to networked storage is dictated by needs that come with server virtualization, such as VM migration, elevating costs and complexity, while taxing performance and management. The survey, with respondents including network and systems administrators and other IT personnel from organizations of all sizes, sheds light on how virtualized infrastructures raise the levels of stress and demand on networked storage, creating a tenuous situation of economic sustainability against the high costs of improved storage performance.
