Juniper EX2500 ethernet switch for high-density 10GbE deployments

Juniper Networks announced the expansion of its Ethernet switching product portfolio with the EX2500 line of 10 Gigabit Ethernet (GbE) switch. The EX2500 line will be targeted at high-density 10GbE deployments where high-performance networking with low latency, high availability and energy efficiencies are key requirements for enterprise and service provider data center networks.

The EX2500 line of 10GbE Ethernet switches address high-performance server access requirements with twenty-four 10 GbE SFP+ ports that deliver wire-speed performance and 700 nanosecond latency. The EX2500 line of Ethernet switches will be offered as fixed-configuration Ethernet platforms that will provide several key business benefits including:

  • Wire-rate Performance: The EX2500 Series will support 480 Gigabit per second (Gbps) throughput (full duplex) in a 1 rack-unit (RU) footprint. All ports are non-blocking with deterministic latency of less than 700 nanoseconds.
  • Deployment Flexibility: The EX2500 Series will support both back-to-front and front-to-back cooling, which will deliver deployment flexibility and consistency with server designs for hot- and cold-aisle layouts. The result will be that network ports can always have the best proximity, front or rear-facing, to allow closer proximity to server ports and thus, keep cable lengths short and easily managed, and performance optimized.
  • High Availability: The EX2500 Series will offer both power and fan redundancy as standard features. The EX2500 Series will come with dual, load-sharing power supplies, as well as redundant, variable-speed fans to protect from single power supply or fan failure.
  • Energy Efficiency: The EX2500 Series will improve availability and cooling efficiency via redundant variable speed fans. The variable speed fans will automatically adjust speed under variant conditions to reduce power consumption.

The EX2500 Series is expected to be available in 2Q 2009. The list price for the EX2500 Series starts at US$18,000.
