QFX5210 Switch Datasheet

The QFX5210 can also be positioned as a lean spine device in a distributed gateway architecture (also known as edge-routed bridging, or ERB). Figure 2 shows QFX5120 switches deployed as access switches configured as distributed gateways and QFX5210 switches deployed as spine switches.

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.

• IP Fabric: For customers looking to build scale-out data centers, an L3 spine-and-leaf Clos fabric is ideal due to its predictable, nonblocking performance and scale characteristics. For example, a two-tier fabric built with the QFX5210 Switch as leafs and QFX10000 Switches as the spine can scale to support up to 18,432 40GbE ports, or 36,864 25GbE or 10GbE server ports in a single fabric.
• Overlays: Customers can deploy overlay networks to provide L2 adjacencies for applications over L3 fabrics. The overlay networks use VXLAN in the data plane and EVPN to program the overlays. The overlays can operate without a controller or can be orchestrated with a fabric management orchestrator to provide L2/L3 overlay virtual networking and security for bare-metal servers and virtual workloads. QFX5210 switches can also integrate with VMware NSX.
• MC-LAG: The QFX5210 supports the MC-LAG protocol between two switches, eliminating Spanning Tree Protocol (STP) in traditional L2 networks when deployed in the aggregation layer. MC-LAG’s active/active operation ensures complete bandwidth utilization between the network’s access and aggregation layers, while the dual control plane technology ensures the highest availability for applications.

Data Center Fabric Management: Juniper^® Apstra provides operators with the power of intent-based network design to help ensure changes required to enable data center services can be delivered rapidly, accurately, and consistently. Operators can further benefit from the built-in assurance and analytics capabilities to resolve Day 2 operations issues quickly.

Apstra key features are:

• Automated deployment and zero-touch deployment
• Continuous fabric validation
• Fabric life-cycle management
• Troubleshooting using advanced telemetry

For more information on Apstra, see Juniper Apstra.

• Flexible connectivity options: The QFX5210 offers a choice of 10GbE, 25GbE, 40GbE, and 100GbE interface speeds for server and intra-fabric connectivity, providing deployment versatility and investment protection.
• Automation and programmability: The QFX5210 supports numerous network automation features, including operations and event scripts, ZTP, and Juniper plug-ins for OpenStack Neutron.
• Flexible Forwarding Table: The QFX5210 switch’s Flexible Forwarding Table (FFT) allows the hardware table to be carved into configurable partitions of L2 media access control (MAC), L3 host, and longest prefix match (LPM) tables. Junos OS provides configurable options through a CLI, enabling each QFX5210 to be optimized for different deployment scenarios.
• Cloud-level scale and performance: The QFX5210 supports best in class cloud scale L2/L3 deployments with a low latency of 600 ns (Store and forward) and with superior scale and performance. The Junos OS provides configurable options through a CLI, enabling each QFX5210 to be optimized for different deployment scenarios.
• MPLS: The QFX5210 supports a broad set of MPLS features, including L3 VPN, RSVP traffic engineering, and LDP to support standards-based multitenancy and network virtualization with per-flow SLAs at scale. The QFX5210 can also be deployed as a low-latency MPLS label-switching router (LSR) or MPLS provider edge (PE) router in smaller scale environments. The QFX5210, along with the Juniper Networks QFX5220, QFX5200, QFX5120, QFX5110, and QFX5100 switches, is among the industry’s most compact, low-latency, high-density, low-power family of switches to offer an MPLS feature set.
• RoCEv2: As a switch capable of transporting data as well as storage traffic over Ethernet, the QFX5210 provides an IEEE data center bridging (DCB) converged network between servers with disaggregated flash storage arrays or an NVMe-enabled storage area network (SAN). The QFX5210 offers a full-featured DCB implementation that provides strong monitoring capabilities on the top- of-rack switch for SAN and LAN administration teams to maintain clear separation of management. The RDMA over Converged Ethernet version 2 (RoCEv2) transit switch functionality, including DiffServ code point (DSCP) priority-based flow control (PFC) and Data Center Bridging Capability Exchange (DCBX) with Explicit Congestion Notification (ECN) are included as part of the default software.
