The QFX5100 line of switches is Juniper Network's second generation of top-of-rack
switch solutions for data centers and campus distribution or aggregation environments.
The QFX5100 portfolio consists of high-performance fixed-configuration switches that
add higher port densities, additional scalability, and improved latency to the QFX Series.

QFX5100 line of switches offer two compact 1 U models and a 2 U model that provide
wire-speed packet performance, very low latency, and rich set of Layer 2 and Layer 3
features. In addition to a high-throughput Packet Forwarding Engine, the performance
of the control plane running on all the QFX5100 switches is enhanced by the 1.5 Ghz
dual-core Intel CPU with 8 GB of memory and 32 GB of solid-state drive (SSD) storage.
The QFX5100-24Q-AA switch has a 2.5 GHz 4-core Intel CPU with 32 GB of memory and
128 GB of SSD storage.
The QFX5100 line of switches include both 10GE and 40GE fixed-configurations:

As shown in Figure 1 on page
Small Form-Factor Pluggable (SFP+) top-of-rack switch with 48 SFP+ ports and
6 Quad SFP+ (QSFP+) ports. Each SFP+ port can operate as a native 10 Gigabit port
or a 1 Gigabit port when 1_Gigabit optics are inserted. Each QSFP+ port (
