Juniper QFX5210 Switch

Network operators are increasingly deploying scale-out spine-and-leaf IP fabric architectures built with fixed-configuration switches to support growing east-west traffic in the data center. The Juniper Networks® QFX5210 Switch is a next-generation, fixed-configuration spine/leaf switch that offers flexible, cost-effective, high-density 10GbE, 25GbE, 40GbE, and 100GbE interfaces for IP fabric networks, providing deployment versatility, investment protection, and future-proofing for today’s data centers. The QFX5210 Switch’s high port density also contributes to simplified Clos architectures, eliminating network tiers while reducing complexity and cost.

Like other Juniper Networks QFX Series Switches, the QFX5210 supports advanced L2, L3, and MPLS features. For large public cloud providers—among the first to adopt 25GbE servers to meet explosive workload growth—the QFX5210 enables very large, dense, and fast IP fabrics based on proven Internet scale technology.

The QFX5210 runs the same reliable, high-performance Junos® operating system used by network operators around the world.00GbE connection, 2x50GbE connections, or 4x25GbE connections using breakout cables. A QSFP+ module can provide a 1x40GbE connection or 4x10GbE connections using breakout cables.

The QFX5210 is a compact, 2 U platform featuring 64 quad small form-factor pluggable plus (QSFP+) transceivers or QSFP28 ports, with two redundant 1100 W AC/DC power supplies and four fan trays.

A QSFP28 module can be used to provide a 1x100GbE connection or 4x25GbE connections using breakout cables. A QSFP+ module can be used to provide a 1x40GbE connection or 4x10GbE connections using breakout cables.

The QFX5210 features a high-throughput 12.8 Tbps Packet Forwarding Engine (PFE). Control plane performance is further enhanced with the Intel Broadwell-DE, 4 Core, 2.2 GHz CPU, and 16 GB DDR4, 100 GB SSD storage.

The QFX5210 can be used in L3 fabrics and L2 networks with multichassis link aggregation (MC-LAG). Customers can choose the architecture that best suits their deployment needs and easily adapt and evolve as requirements change over time. The QFX5210 switch serves as a universal building block for these switching architectures, enabling data center operators to build cloud networks their way.
