| Advanced Layer 3 Modular Switch
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.
