Product Description
The Juniper Networks® QFX5120 Switch delivers high scale, high availability, and high performance for data center and campus deployments. The QFX5120 switch is a versatile routing and switching platform addressing higher server access speed and campus distribution use cases while offering high-density 1GbE/10GbE/25GbE and 100GbE uplinks for collapsed spine data center or campus core deployments.
Product Options
The QFX5120 Switch includes four compact 1 U platforms-the QFX5120-48Y, the QFX5120-48YM, the QFX5120-48T, and the QFX5120-32C-that provide wire-speed packet performance, very low latency, and a rich set of Junos® operating system features.
QFX5120-48Y
The QFX5120-48Y is a 25GbE/100GbE data center leaf and campus distribution switch featuring:
- 48 25GbE (SFP28)/10GbE (SFP+)/1GbE (SFP) downlink ports
- Eight 100GbE (QSFP28)/40GbE (QSFP+) uplink ports
- Up to 4 Tbps L2 and L3 performance (bidirectional), with latency as low as 550 nanoseconds
- A 2.2 GHz quad-core Intel CPU with 16 GB memory and 50 GB SSD storage
Using breakout cables, each of the eight 100GbE QSFP28 ports can be broken into four 25GbE SFP28 ports, while each 40GbE quad small form-factor pluggable plus (QSFP+) transceiver ports can be broken into four 10GbE small form-factor pluggable plus (SFP+) transceiver ports, increasing the total number of supported 25GbE and 10GbE ports per switch to 80.
QFX5120-48YM
The QFX5120-48YM is a 10GbE/25GbE/100GbE data center leaf and campus distribution switch featuring:
- 48 25GbE (SFP28)/10GbE (SFP+)/1GbE (SFP) downlink ports
- Eight 100GbE (QSFP28)/40GbE (QSFP+) uplink ports
- Up to 4 Tbps L2 and L3 performance (bidirectional), with latency as low as 550 nanoseconds
- Media Access Control Security (MACsec) AES-256 support across all ports
- A 2.9 GHz quad-core Intel CPU with 16 GB memory and 100 GB SSD storage
When using breakout cables, two of the 100GbE QSFP28 ports (ports 50 and 52) can be broken into four 25GbE SFP28 or four 10GbE SFP+ ports, increasing the maximum number of 10GbE/25GbE ports supported to 56. When using breakouts, the total number of all ports on the switch, including 6x100GbE ports and 56×10/25GbE, is 62.
QFX5120-48T
The QFX5120-48T is a 10GbE/100GbE data center leaf and campus distribution switch featuring:
- 48 dual-speed 1GbE/10GbE RJ-45 copper downlink ports
- Six dual-speed 100GbE (QSFP28)/40GbE (QSFP+) uplink ports
- Up to 2.16 Tbps L2 and L3 performance (bidirectional), with latency as low as 550 nanoseconds
- A 2.2 GHz quad-core Intel CPU with 16 GB memory and 100 GB SSD storage
