An integrated data center combines a storage controller and appliances onto a computer platform. Storage controller component executes on the computer platform with exclusive access to a first storage controller host bus adapter coupled to a storage shelf A virtualized instance of the hardware from the computer platform is provisioned to deliver application services from an appliance component which may share the processing resources from the computer platform through different virtual machines. An appliance host bus adapter from the computer platform is exclusively associated to the appliance component. This provides the appliance component exclusive control of the appliance host bus adapter passing through the virtualized instance of the hardware. To access the storage devices, appliance host bus adapter and corresponding appliance component are coupled with a second storage controller host bus adapter associated with the storage controller component.
