Juniper Networks EX4500-40F-VC1 Ethernet Switch with Virtual Chassis Module

EX4500 Overview:

The Juniper Networks EX4500 line of Ethernet switches delivers a scalable, high-performance platform for supporting high-density 1 gigabit per second (Gpbs) and 10 Gbps data center top-of-rack as well as data center, campus, and service provider aggregation deployments.

Featuring up to 48 wire-speed 10-Gigabit Ethernet (10GbE) ports in a two rack unit (2U) platform, the Juniper Networks® EX4500 Ethernet Switch delivers Layer 2 and Layer 3 connectivity to networked devices such as servers and other switches. The EX4500 base switch provides 40 fixed 10GbE pluggable ports that can also support GbE connectors for added flexibility. Two optional high-speed uplink modules offer four additional 10GbE small form-factor pluggable transceiver (SFP+) ports each for connecting to upstream devices.

By targeting high-density 10GbE top-of-rack and aggregation deployments in the data center, campus, and service provider environments, EX4500 switches perfectly complement the Juniper Networks EX Series Ethernet Switch product family: the Juniper Networks EX2200 line and EX3200 line designed for low-density access deployments; the EX4200 line designed for data center and campus GbE access and aggregation deployments; and the EX8200 line of Ethernet switches designed for data center and campus core and aggregation environments.

Virtual Chassis Technology

The EX4500 supports Juniper Networks’ unique Virtual Chassis technology, which enables multiple interconnected switches to operate as a single, logical device with a single IP address. When deployed in a Virtual Chassis configuration, the EX4500 switches are connected over a 128 Gbps backplane using Virtual Chassis interconnect cables. EX4500 switches can also be interconnected using a link aggregation (LAG) of up to eight SFP+ 10 GbE line-rate links, allowing switches to reside in different locations. Interconnected switches are monitored and managed as a single device, enabling enterprises to separate physical topology from logical groupings of endpoints and allowing more efficient resource utilization.

In the data center, using Virtual Chassis technology at the top of rack or end of row to aggregate servers provides flexibility in the deployment of uplinks. Rather than requiring redundant links for each physical switch to ensure high availability, redundant links are only needed for each Virtual Chassis group. EX4500 and EX4200 switches may be combined within a single Virtual Chassis configuration to support environments where both GbE and 10GbE servers are present.

Features & Benefits:

The EX4500 Ethernet switches include the following key features and benefits.

High Performance

Each EX4500 supports 480 Gbps of bandwidth with 48 line-rate 10 Gbps ports at all packet sizes or 14.88 Mpps per port at the minimum Ethernet frame size.

High Availability

The EX4500 switches offer dual internal load sharing AC power supplies, and redundant variable-speed fans as standard features, protecting the switch from a single power supply or fan failure. DC power options will be available in the future.

Energy Efficient

Consuming less than eight watts per 10GbE interface, the EX4500 offers a low power solution for 10GbE top-of-rack, end-of-row, and aggregation deployments. The EX4500 switches also improve cooling efficiency with redundant variable-speed fans that automatically adjust their speed based on existing conditions to reduce power consumption.

Small Footprint

The EX4500 supports up to 48 wire-speed 10GbE ports in a single 2U platform.

Available

The EX4500 offers redundant cooling and is available with redundant power supplies. A Virtual Chassis configuration – with several EX4500 switches – provides redundant routing engines and a network fabric. In addition, the EX4500 offers many other features that increase the availability of your network, including Open Shortest Path First (OSPF), Equal-cost multipath (ECMP), link aggregation group (LAG), links distributed across multiple slots, Graceful Routing Engine switchover (GRES), graceful protocol restart, and Quality of Service (QoS) to prioritize timesensitive data.

Adaptable and Modular

As your business grows, your needs change and your network needs to evolve. With its small form factor (2RU) and complete switch features (with a supervisor, up to 48 10GbE ports, available in one box), the EX4500 can be easily redeployed in different environments and physical layouts. The dual-speed interfaces of the EX4500 enable you to transition your environments from GbE to 10GbE. The capacity of your EX4500 switch can easily be virtually increased by simply adding more switches to the Virtual Chassis configuration, without increasing the number of switches you have to manage. The modularity of an EX4500 with Virtual Chassis is clearly comparable to the adaptability of a modular switch.

Junos Operating System

The EX4500 runs the same Juniper Networks Junos operating system that is used by other EX Series Ethernet Switches, as well as all Juniper Networks routers and Juniper Networks SRX Series Services Gateways. By utilizing a common operating system, Juniper Networks delivers a consistent implementation and operation of control plane features across all products. To maintain that consistency, Junos OS adheres to a highly disciplined development process that uses a single source code, follows a single quarterly release train, and employs a highly available modular architecture that prevents isolated failures from bringing down an entire system.

These attributes are fundamental to the core value of the software, enabling all Junos OS-powered products to be updated simultaneously with the same software release. All features are fully regression tested, making each new release a true superset of the previous version; customers can deploy the software with complete confidence that all existing capabilities will be maintained and operate in the same way.

Junos OS utilizes a single source code, adheres to a consistent and predictable release train, and employs a single modular architecture.

Management Options

Up to four different system management options are available for the EX4500 Ethernet switches.

1. The standard Junos OS command-line interface (CLI) offers the same granular management capabilities and scripting parameters found in any router powered by the Junos OS.
2. The EX4500 also includes the integrated Juniper Networks J-Web Software, an embedded web-based device manager that allows users to configure, monitor, troubleshoot, and perform system maintenance on individual switches via a browserbased graphical interface.
3. EX4500 performance, configuration, and fault data can also be exported to leading third-party management systems such as HP OpenView, IBM Tivoli, and Computer Associates Unicenter software, providing a complete, consolidated view of network operations.
4. The EX4500 is also supported by Juniper Networks Junos® Space*, an open, programmable application platform for hosting a comprehensive suite of network operational application tools that provide a smart, simple, and open approach for automating the deployment and operation of a Juniper infrastructure.
   Explicitly designed to allow partners and customers to build and deploy smart, simple, and easy-to-use applications, Junos Space provides multiple management and infrastructure applications for managing Juniper resources and assets, including inventory management, device and interface configuration, automated software management and deployment, and event-driven fault management.

Data Center and Campus Advantages:

The EX4500 is an ideal switch for both data center and campus aggregation deployments. It offers an economical, power efficient and compact solution for aggregating 10GbE uplinks. Its feature set provides simplicity, scalability, availability, adaptability and modularity to your network.

Simple

Virtual Chassis on the EX4500 brings important simplification features to the campus aggregation layer. It eliminates the need for Spanning Tree, VRRP, complex routing, or VLAN configuration, therefore simplifying the management of the network. The EX4500 with Virtual Chassis reduces the number of virtual devices to manage and can even lead to a reduction in the number of network tiers. A single Virtual Chassis configuration can also span multiple nodes, reducing the need for uplinks and limiting the need for larger and more expensive nodes on superior tiers.

Scalable

With Juniper Networks Junos® operating system shared across the entire EX Series platform and the EX4500 positioned in the top-of-rack and campus aggregation, the short learning curve enables you to quickly manage a complete architecture from one common set of instructions and one pane of glass. In addition, a single EX4500 can support up to 48 10GbE ports at line rate, enabling you to scale even in the most demanding environments.

In addition, Virtual Chassis technology makes it easy to scale while reducing the complexity of managing a larger network; by adding switches to a Virtual Chassis configuration, it is possible to increase the number of ports without increasing the number of devices to manage.

Network Deployments:

Campus Deployments

The EX4500 also offers an economical, power efficient and compact solution for aggregating 10GbE uplinks from access devices in building and campus deployments (see Figure 3). The switch’s dual-speed interfaces also support environments transitioning from GbE to 10GbE.

The EX4500 easily meets enterprise core switch requirements, delivering wire-speed performance on every port, full device redundancy, support for Layer 3 dynamic routing protocols such as RIP and OSPF, and a comprehensive security and quality-ofservice (QoS) feature set.

Data Center Deployments

The EX4500 Ethernet Switch is designed for demanding data center applications where high performance, high availability, and energy efficiency are key requirements (see Figure 1). Operating at wire speed, the EX4500 switches deliver 714 Mpps throughput and a data rate of 960 Gbps (full duplex) for both Layer 2 and Layer 3 protocols. An industry first and only, EX4500s can be interconnected in a Virtual Chassis configuration that also includes EX4200s, creating a single logical switch that offers a variety of port and density options for mixed server environments.

Flexible deployment options enable the EX4500 to support backto- front and front-to-back cooling, which ensures consistency with server designs for hot and cold aisle deployments. Front- and rear-facing configuration options ensure closer proximity to server ports, optimizing performance and keeping cable lengths short and manageable. The EX4500 is also very environmentally conscious, drawing less than eight watts per port under maximum load.

For small data centers, the EX4500, in a Virtual Chassis configuration, is ideally deployed as the aggregation/core switch, aggregating 10GbE uplinks from EX4200 Virtual Chassis configurations in the access layer (see Figure 2).

Customers introducing 10GbE into their racks will be able to use the EX4500 to add 10GbE-attached servers, iSCSI, and networkattached storage (NAS) with minimal impact to the current switching infrastructure.

The EX4500 also includes hardware support for the Data Center Bridging (DCB) feature set, also referred to as Converged Enhanced Ethernet (CEE). DCB is a collection of individual IEEE standards that allow for Ethernet-based I/O and network convergence, including support for FCoE.
