QFX5100-48S-3AFO Juniper QFX5100 Series 48-Port x SFP+/SFP, 6 x QSFP+ Managed Rack-Mountable 1U Network Switch

Juniper QFX5100-48S-3AFO

The Juniper QFX5100-48S-3AFO is a 48-port managed 10 Gigabit Ethernet switch from Juniper, part of the QFX Series, built for virtualized server farms, private clouds and storage networks that need low latency and high bandwidth. It belongs to a family built for data center switching.

The port configuration is 48 x SFP, 6 x QSFP, so you can connect end devices and uplinks to suit your design. The 40GbE ports are well suited to backbone links, NAS connections and other high-traffic paths. Pluggable fiber slots let you choose the right transceiver for short- or long-distance links between buildings or racks.

Full management capabilities let your IT team tune performance, enforce policies and monitor every port. It runs on Junos OS, so it fits existing management tools and operating procedures. Bundling ports with link aggregation adds both throughput and redundancy between switches. Traffic prioritization ensures real-time applications get the bandwidth they need.

The 1U rack-mountable design makes installation straightforward in its intended location. Centralizing wired connections on one switch makes the network easier to understand and maintain. Leaf-spine fabrics use switches like this to connect servers and feed high-speed links to the spine. It suits top-of-rack placement, which keeps server cabling short and organized. Dense, low-latency switching suits hypervisor clusters and storage networks. Modern compute and storage platforms need exactly this kind of high-bandwidth switching. Whether you are building a new network or replacing an existing unit, the QFX5100-48S-3AFO delivers Juniper managed 10 Gigabit Ethernet switching that fits the job.
