QFX5110-48S-AFO

Data centers are rapidly adopting cloud services, whether completely off-premises models or hybrid models with critical services offered through on-premise private clouds. The tremendous growth of off-premises cloud services, coupled with the widespread adoption of overlay technologies, has created a need for highly agile switching platforms that can satisfy the demands of these evolving data centers.

The high-performance Juniper Networks® QFX5110 line of Ethernet switches fit the bill, providing the foundation for dynamic data centers. As a critical enabler for IT transformation, the data center network supports cloud and SDN adoption, network virtualization, integrated/scale-out storage, and the rapid deployment and delivery of mission-critical applications that significantly increase east-west traffic within the data center. Furthermore, increasing demand for 100GbE spine ports is driving the need for 100GbE uplinks for all server access speeds, including 10GbE and 40GbE. The QFX5110 includes 100GbE uplinks, enabling it to support a diverse set of switching architectures, including fabric, Layer 3, and spine-and-leaf deployments, enabling users to easily adapt as requirements change over time. The QFX5110 switch can be positioned in campus distribution and core deployments.

• Automation

• The QFX5110 switches support a number of features for network automation and plug-and-play operations. Features include zero touch provisioning, operations and event scripts, automatic rollback, and Python scripting. The switch also supports integration with VMware NSX Layer 2 Gateway Services, and OpenStack.

• Flexible Forwarding Table

• The QFX5110 includes a Unified Forwarding Table (UFT), which allows the hardware table to be carved into configurable partitions of Layer 2 media access control (MAC), Layer 3 host, and longest prefix match (LPM) tables. In a pure L2 environment, the QFX5110 supports 288,000 MAC addresses. In Layer 3 mode, the table can support 208,000 host entries. In LPM mode, it can support 128,000 prefixes. Junos OS provides configurable options through a CLI so that each QFX5110 can be optimized for different deployment scenarios.

• Intelligent Buffer Management

• The QFX5110 switches have a total of 16 MB shared buffers. While 25% of the total buffer space is dedicated, the rest is shared among all ports and is user configurable. The intelligent buffer mechanism in the QFX5110 effectively absorbs traffic bursts while providing deterministic performance, significantly increasing performance over static allocation.

• MPLS—QFX5110 switches support a broad set of MPLS features, including L3 VPN, IPv6 provider edge router (6PE), RSVP traffic engineering, and LDP to allow standards-based network segmentation and virtualization. This enables the QFX5110 to be deployed as a low-latency MPLS label-switching router (LSR).

• VXLAN Overlays

• The QFX5110 switch is capable of supporting Layer 2 and Layer 3 gateway services. Customers can deploy overlay networks to provide Layer 2 adjacencies for applications over Layer 3 fabrics. The overlay networks utilize VXLAN in the data plane and EVPN or OVSDB to program the overlays. The overlays can operate without a controller, or they can be orchestrated with an SDN controller.
