Server virtualization is the accepted method of deployment today for most private clouds, development and testing environments, and public clouds, as well as for many enterprise production applications. Some of the reasons for deploying server virtualization are to save on power, cooling, and space; obtain faster server provisioning; eliminate hardware vendor lock-in; increase uptime; and benefit from a range of operational advantages that are not available when applications run directly on physical servers.
Similar to server virtualization, ScaleIO ECS delivers a game-changing proposition for enterprise storage environments in need of simpler, more automated administration, cost savings, and infrastructure efficiencies. ScaleIO ECS provides benefits that just aren't possible with traditional SAN storage.
