908
| Advanced Layer 3 Modular Switch
Diagram 2 illustrates the SwitchBlade x908 in an Enterprise Campus network.
Education providers are able to offer high speed connection to the desktop
for power users and utilize high-capacity uplinks for maximum throughput of
high-density traffic.
Servers and management work stations are attached directly to the core of
the network using Gigabit Ethernet via XEM-12T modules. Links from the
server farm to the core can be trunked to allow for greater bandwidth and
resiliency. Industry leading QoS features on the SwitchBlade x908 allow
important server traffic to be prioritized over less critical network traffic.
In the main building, edge switches uplink to the SwitchBlade x908 core switch,
using fiber connections to the XEM-12S, a 12 port (100/1000 BASE-X SFP)
expansion module. Other buildings uplink to the core using 10 Gigabit
Ethernet links from x900 switches to the XEM-1XP modules on the
SwitchBlade x908. This enables large files, video and voice to be transferred
without compromising service agreements.
For further expansion in the core, or in the other departments, the XEM-STK
stacking module provides two proprietary 30Gbps stacking links using special
stacking cables. Excellent scalability can be achieved in that individual stacked
nodes can be inserted into, and removed from, the stack as bandwidth and
feature requirements in the network evolve. Further to this, the
SwitchBlade x908 supports proprietary 80Gbps stacking links allowing a further
SwitchBlade x908 to be added to the core without compromising bandwidth
between the units.
