Data Center LAN Migration Guide - Juniper Networks

Data Center LAN Migration Guide
A key benefit of using Junos OS is lower TCO as a result of reduced operational challenges and improved operational
productivity at all levels in the network.

Figure 8: Junos OS lowers operations costs across the data center
An independent commissioned study conducted by Forrester Consulting3 (www.juniper.net/us/en/reports/junos_tei.pdf)
found that the use of Junos OS and Juniper platforms produced a 41% reduction in overall operations costs for network
operational tasks including planning and provisioning, deployment, and planned and unplanned network events.
Juniper Platform Overview
The ability to migrate from a three-tier network design to a simpler two-tier design with increased performance,
scalability, and simplicity is predicated on the availability of hardware-based services found in networking platforms
such as the EX Series Ethernet Switches, MX Series 3D Universal Edge Routers, and the SRX Series Services Gateways.
A consistent and unified view of the data center, campus, and branch office networks is provided by Juniper’s “single
pane of glass” management platforms, including the recently introduced Junos Space.
The following section provides a brief overview of the capabilities of Juniper’s platforms. All of the Junos OS-based
platforms highlighted provide feature consistency throughout the data center LAN and lower TCO.

Typically deployed at the access layer in a data center, Juniper Networks EX4200 Ethernet Switch provides chassisclass,
high availability features, and high-performance throughput in a pay as you grow 1 rack unit (1 U) switch.
Depending on the size of the data center, the EX4200 may also be deployed at the aggregation layer. Offering flexible
cabling options, the EX4200 can be located at the top of a rack or end of a row. There are several different port
configurations available with each EX4200 switch, providing up to 48 wire-speed, non-blocking, 10/100/1000 ports
with full or partial Power over Ethernet (PoE). Despite its small size, this high-performance switch also offers multiple
GbE or 10Gbe uplinks to the core, eliminating the need for an aggregation layer. And because of its small size, it takes
less space, requires less power and cooling, and it costs less to deploy and maintain sparing.
Up to 10 EX4200 line switches can be connected, configured, and managed as one single logical device through built-in
Virtual Chassis technology. The actual number deployed in a single Virtual Chassis instance depends upon the physical
layout of your data center and the nature of your traffic. Connected via a 128 Gbps backplane, a Virtual Chassis can be
comprised of EX4200 switches within a rack or row, or it can use a 10GbE connection anywhere within a data center or
across data centers up to 40 km apart.
