Product Overview The Juniper Networks QFX3500 Switch delivers a high-performance, ultra low latency, feature rich Layer 2 and Layer 3 solution for the most demanding data center environments. Featuring standards-based Fibre Channel I/O and iSCSI convergence capabilities in a compact form factor, the QFX3500 is a versatile, high density 10GbE platform that also delivers a fabric-ready edge solution for the Juniper Networks QFabric architecture. Product Description The high-performance Juniper Networks® QFX3500 Switch addresses a wide range of deployment scenarios, which include traditional data centers, virtualized data centers, high-performance computing, network-attached and iSCSI storage, FCoE convergence, and cloud computing. Featuring 48 dual-mode small form-factor pluggable transceiver (SFP+/SFP) ports and four quad small form-factor pluggable plus (QSFP+) ports in a 1 U form factor, the QFX3500 Switch delivers feature rich Layer 2 and Layer 3 connectivity to networked devices such as rack servers, blade servers, storage systems, and other switches in highly demanding, high-performance data center environments. For end-to-end convergence, the QFX3500 has extensive DCB capabilities including specific iSCSI support. For FCoEbased converged server edge access environments, the QFX3500 is also a standardsbased Fibre Channel over Ethernet (FCoE) Transit Switch and FCoE to Fibre Channel (FCoE-FC) Gateway, enabling customers to protect their investments in existing data center aggregation and Fibre Channel storage area network (SAN) infrastructures. The Juniper Networks QFX3500 is a highly flexible data center switch that offers several deployment options including Fabric, Virtual Chassis and MC-LAG. When deployed with other components of the Juniper Networks QFabric™ family, including the QFX3100 QFabric Director and the QFX3600-I QFabric Interconnect (in a QFX3000-M QFabric System) or QFX3008-I QFabric Interconnect (in a QFX3000-G QFabric System), the QFX3500 delivers a fabric-ready edge solution that contributes to a highperformance, low latency, single-tier data center fabric. By converting any 10GbE or 40GbE port into a Virtual Chassis connection, the QFX3500 can leverage all the benefits of Juniper’s industry-leading Virtual Chassis technology including simplified management and operations, as well as high availability. As a leaf node in Juniper’s new Virtual Chassis Fabric architecture, the QFX3500 switch offers deterministic rack-to-rack throughput, high availability and a smooth transition path from 1GbE to 10/40GbE. The QFX3500 can be deployed along with with Juniper QFX3600, EX4300 and QFX5100 switches in the same Virtual Chassis and Virtual Chassis Fabric configuration. For added configuration flexibility, up to 36 of the QFX3500’s 48 pluggable SFP+ ports can be used in 10GbE or 1GbE mode with up to 18 of the 1GbE ports being copper. The remaining 12 ports can be used to support 2, 4, or 8 Gbps Fibre Channel modes as well as 10GbE. Each of the four QSFP+ high speed ports can operate in 4x10GbE mode and are capable of supporting 40 Gbps optics* in the future, providing investment protection.

• Insight Technology for Analytics: The QFX3500 provides dynamic buffer utilization monitoring and reporting with an interval of 10 milliseconds to provide microburst and latency insight. It calculates both queue depth and latency, and logs messages when configured thresholds are crossed. Interface traffic statistics can be monitored at two-second granularity. The data can be viewed via CLI, system log, or streamed to external servers for more analysis. Supported reporting formats include Java Script Object Notification (JSON), CSV and TSV. These files can be consumed by orchestration...
