Internal PSUs eliminate the need for an external

Redundant Power Supply (RPS) which occupies

valuable rack space. Built-in redundancy guarantees

the continued delivery of essential services.

Comprehensive low-latency Quality of Service

(QoS) features operating at wire-speed, provide

flow-based traffic management with full

classification, prioritization, traffic shaping and

min/max bandwidth profiles. For Enterprise

customers, the SwitchBlade x908 QoS features

protect productivity by guaranteeing

performance of business-critical applications

(including VoIP services), and help to restore and

maintain responsiveness of Enterprise applications

in the workplace.
