Allied Telesyn Summit 4

Allied Telesyn Summit 4 ... switches share a common non-blocking switch architecture that provides scalability in four areas: speed, bandwidth, network size and quality of service (QoS).

Six Gigabit Ethernet ports and 16 10/100 Mbps auto-negotiating Ethernet ports are featured with the Summit4. It delivers an integrated server switching solution with a unique mix of ports that can be load-shared, or trunked, to match network bandwidth with server performance. Summit4 can integrate server farms into the enterprise network with integrated routing. And with ExtremeWare's Policy-Based Quality of Service, Summit4 delivers bandwidth management and control over server traffic, regardless of server type or location.

The port density, fault tolerance and performance of Summit4 scale dramatically with the Summit Virtual Chassis, a high-speed external backplane that interconnects up to eight stacked or distributed Summit switches into one system. Connected to a Virtual Chassis SummitLink port, Summit switches combine the flexibility and low entry-cost of a stackable with the fault tolerance and high port-density of a modular system. Each Summit system is pre-installed with ExtremeWare, a standards-based software suite that delivers in the ability to manage and control bandwidth on a network. ExtremeWare combines standards with advanced features to deliver Policy-Based QoS that includes bandwidth reservation, IP routing, IP multicast control and VLAN switching. Policy-Based QoS lets network managers prioritize and allocate bandwidth to many different types of network traffic - right down to the TCP/UDP session and without significant performance penalty.
