The ASA 5585-X adaptive security appliance featuring MultiScale™ is a two-rack-unit (2RU), two-slot chassis. Supporting one of the highest performance-density firewalls on the market, the design of the ASA 5585-X provides high scalability not only in terms of throughput, but also high connection speed and maximum connections. Connection speed and maximum connection requirements are growing much faster than throughput in most customer data center networks. The capabilities of the ASA 5585-X help you simultaneously meet scalability challenges in throughput, connection capacity, and connection speed in the data center.
