Scalable Performance2.

a. EX8200 line

To meet the aggregation demands of even the largest data center, the EX8200 line of Terabit-chassis switch

delivers a powerful, high-density, high-performance solution. Capable of up to 3.2 Tbps throughput, the

EX8200 modular Ethernet switches offer up to 64 (eight-slot chassis) or 128 (16-slot chassis) wire-speed 10

GbE ports. The EX8200 line delivers 200 Gbps of switching capacity per slot, enabling the future addition of 100

Gbps uplinks. By providing capacity now, the EX8200 line of switches allow users to easily migrate to higher-

speed connections when they are ready—without requiring any changes to the switch fabric, Route Engines,

backplane, power supplies or cooling system. The EX8200 line also offers a redundant control plane and runs

JUNOS Software for maximum software HA.

The EX8200 line of switches include integrated security features to guard against intruders or other external

threats. Integrated anomaly-based threat detection provides additional protection by identifying and blocking

distributed denial of service (DDoS) attacks. Taking advantage of behavioral threat detection algorithms, the

EX8200 line of switches are also capable of identifying and closing half-open sessions—important for defending

against zero-day threats for which no signatures exist.

b. Virtual Chassis

The EX4200 Ethernet Switches with Virtual Chassis technology can be utilized in smaller aggregation

configurations requiring high-density 1000BASE-X fiber GbE ports. For typical aggregation environments

requiring 48 GbE SFP fiber ports and four 10 GbE uplinks, two 24-port EX4200 Ethernet Switches deliver the

same wire-speed port densities and functionality as the most popular chassis-based solution—at one-sixth the

size, one-fifth the power, and one-third the cost.

CAPEX and OPEX Savings3.

Typically more than two layers of legacy Layer 3 switches are required to achieve the wire-speed port densities

demanded by today’s high-performance data center. The Juniper Networks EX Series Ethernet Switches,

however, meet these needs and also enable the collapse of the number of aggregation layers, creating a direct

positive impact on the economics of networking.

JUNOS Software also simplifies network operations and lowers operating expense on all fronts, from upgrades

and moves, adds and changes to troubleshooting and problem resolution.

The EX Series switches deliver greater value while reducing capital and operating expenses. This frees up

valuable IT resources that may be invested in new technologies to improve business productivity and further

streamline operations.

Collapsing the Aggregation Layer into the Core Layer

An aggregation layer is not always necessary and may be eliminated in some data center LAN configurations. Based

on port density, aggregation throughput, and oversubscription requirements, the aggregation layer may be collapsed

into the core layer. For more detail, please view the Data Center Core Layer Design Recommendations section.
