Goals of the Virtual Chassis system
The aim of the Virtual Chassis system is to eliminate the requirement to pay for capacity in a chassis switch that will not be used right away. "Every device has a route engine, redundant power supplies and fans are hot swappable. You can have 10 members in a virtual chassis architecture with 480 Gigabit [Ethernet] ports. This density is tremendous leverage for customers who want to pay as you grow. For Gigabit Ethernet aggregation, there is no reason why customers need to pay what they are now paying for modular systems," said Sheth.The EX 3200 series, aimed at branch or regional offices, provide 24 and 48 ports of 10/100/1000 connectivity with either full or partial power-over-Ethernet support. They offer optional four-port Gigabit Ethernet or two-port 10 Gigabit Ethernet uplinks. The EX 8200 supports 64 ports or 128 ports. Juniper, which late last year announced that is it opening up its JUNOS operating system to select partners to allow them to add more value on top of Juniper's routers, also rallied Independent Software Vendors around the new EX switch line. "The closed network architectures deployed today forced security applications to the edge of the network and led our clients to build [networks with] hard edges, but soft chewy centers," quipped Chris Rouland, CTO of IBM's Internet Security Systems at Juniper's press event. "The ability to integrate [with JUNOS] opens the network fabric to ISVs," he added.
Juniper also integrated its Unified Access Control security and implemented Application-Specific Integrated Circuit-based Sflow support in the new switches to allow users to gather network statistics and identify applications.
