Juniper Networks is a leader in the networking industry and their QFX-5700 Switch stands as one of the most powerful switches currently on the market. If you’re looking to upgrade your network, this piece of hardware might be just what you need. This article will explore everything that you need to know about the Juniper QFX-5700 Switch, including its features, benefits, and more. Whether you’re an IT professional looking to upgrade your existing system or someone just getting into the world of networking, this article will provide all the information you need to properly evaluate the switch.
The QFX5700 Switch offers a high-density, cost-optimized, 5 U 400GbE, 8-slot fabric-less modular platform, ideal for data centers where capacity and cloud services are being added as business needs grow. These services require higher network bandwidth per rack, as well as flexibility, making the 10/25/40/50/100/200/400GbE interface options of the QFX5700 switch ideal for server and intra-fabric connectivity. The QFX5700 is an optimal choice for spine-and-leaf deployments in enterprise, service provider, and cloud provider data centers.
Coupled with the widespread adoption of overlay technologies, the QFX5700 lays a strong foundation for your evolving business and network needs, offering deployment versatility to future-proof your network investment.
Increased Scale and Buffer
The QFX5700 provides enhanced scale with up to 1.24 million routes, 80,000 firewall filters, and 160,000 media access control (MAC) addresses. It supports high numbers of egress IPv4/IPv6 rules by programming matches in egress ternary content addressable memory (TCAM) along with ingress TCAM.
132MB Shared Packet Buffer
Today’s cloud-native applications have a critical dependency on buffer size to prevent congestion and packet drops. The QFX5700 has a 132 MB shared packet buffer that is allocated dynamically to congested ports.
Programmability
The QFX5700 revolutionizes performance for data center networks by providing a programmable software-defined pipeline in addition to the comprehensive feature set provided in the Juniper Networks QFX5120 Switch line. The QFX5700 uses a compiler-driven switch data plane with full software program control to enable and serve a diverse set of use cases, including in-band telemetry, fine-grained filtering for traffic steering, traffic monitoring, and support for new protocol encapsulations.
Power Efficiency
With its low-power 7nm technology, a fully loaded and fully redundant QFX5700 consumes typically 2,870 W, bringing improvements in speed, less power consumption, and higher density on a chip.
Additionally, the QFX5700 supports 610,000 LPM routes and 80,000 host routes on IPv6, 128-way equal-cost multipath (ECMP) routes, and a filter that supports 80,000 ingresses and 18,000 egresses exactly match filtering rules. The QFX5700 supports up to 128 link aggregation groups, 4096 VLANs, and Jumbo frames of 9216 bytes. Junos OS Evolved provides configurable options through a CLI, enabling each QFX5700 to be optimized for different deployment scenarios.
The switches control and data plane processes can run in parallel, maximizing CPU utilization, providing support for containerization, and enabling application deployment using LXC or Docker.
The QFX5700 can be deployed as a universal device in cloud data centers to support 100GbE server access and 400GbE spine-and-leaf configurations, optimizing data center operations by using a single device across multiple network layers. The QFX5700 can also be deployed in more advanced overlay architectures like an EVPN-VXLAN fabric. Depending on where tunnel terminations are desired, the QFX5700 can be deployed in either a centrally routed or edge-routed architecture.
Conclusion
The Juniper QFX-5700 switch powerful and reliable piece of hardware that can help facilitate the smooth operation of your network. With its advanced features such as support for 10GBASE-T, dynamic power saving, and multiple management tools, this switch is an excellent choice for businesses looking to upgrade their networks. By understanding all the components and capabilities of this impressive switch you’ll be able to make sure it’s up to the job no matter how demanding your requirements are.
