SANbox 5600 lets you start small, then scale with your company's needs using state of the art 10Gb Fibre Channel stacking technology typically found only in high end director products. As proven in the Ethernet world, stackable architectures cut costs and increase stability by providing a dedicated, highly expandable transport for aggregate ISL traffic eliminating the disruption, port waste and management hassles associated with using regular device ports for inter switch links. It's like having the performance and hands off convenience of an expensive chassis switch without the cost overhead of a chassis. Need more server or storage ports. There's no need to move existing cables or disrupt devices your ISL bandwidth expands automatically with each switch.
