Juniper Adds 24-Port 10 Gigabit Ethernet Switch

Juniper Networks is expanding its EX Ethernet switching product portfolio with a new EX2500 line of 10 Gigabit Ethernet (GbE) switches targeted at high-density 10GbE deployments. The EX2500 line of 10GbE Ethernet switches offer 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. Key features include:

  • 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.


Juniper's EX Series switching family now includes the EX2500, EX3200, EX4200 and new EX8200 lines.

  • In November 2008, Juniper Networks introduced a data center switching solution that leverages its EX series Ethernet switches, high-densities of 1 and 10 Gigabit Ethernet (GbE) ports, JUNOS operating software and "virtualized chassis" technology. Essentially, the new data switching solution aims to remove an entire tier of aggregation switches and supporting security platforms typically seen in today's mid-to-large sized corporate data centers. Juniper achieves this by allowing up to ten 48-port EX 4200 switches to be logically aggregated into a single virtual switch. This saves interconnect and uplink ports, as well as eliminates the need to deploy the typical panoply of security appliances. A single SRX-series platform can now serve this role. Juniper estimates its data center architecture can significantly reduce network complexity and total cost of ownership by up to 52 percent in capital expenditures, up to 44 percent in power, up to 44 percent in cooling and up to 55 percent in rack space. In addition, by deploying Juniper MX-series edge routers, IP/MPLS Layer 3 VPNs can be mapped via the EX switches directly to individual servers in the data center. Mirroring and back-up applications can also be mapped via VPNs to secondary data centers.
