ARUBA CX 8325 SWITCH SERIES

High Performance Enterprise Campus and Data Center Switch

PRODUCT OVERVIEW

The Aruba CX 8325 Switch Series oers a exible and

innovative approach to addressing the application, security,

and scalability demands of the mobile, cloud and IoT era.

Theseswitches serve the needs of the next generation

core and aggregation layer, as well as emerging data center

requirements at the Top of Rack (ToR) and End of Row (EoR).

They provide over 6.4Tbps of capacity, with line-rate Gigabit

Ethernet interfaces including 1Gbps, 10Gbps, 25Gbps,

40Gbps, and 100Gbps.

The 8325 series includes industr y-leading line rate

ports 1/10/25GbE (SFP/SFP+/SFP28) and 40/100GbE

(QSFP+/QSFP28) with connectivity in a compact 1U form

factor. These switches oer a fantastic investment for

customers wanting to migrate from older 1GbE/10GbE to

faster 25GbE, or 10GbE/40GbE to 100GbE ports.

PRODUCT DIFFERENTIATORS

AOS-CX - a modern software system

The Aruba CX 8325 Switch Series is based on AOS-CX, a

modern, database-driven operating system that automates

and simplies many critical and complex network tasks.

A built-in time series database enables customers and

developers to utilize software scripts for historical

troubleshooting, as well as analysis of past trends. This helps

predict and avoid future problems due to scale, security, and

performance bottlenecks.

Our AOS-CX software also includes Aruba Network Analytics

Engine (NAE) and support for Aruba NetEdit. Because AOS-

CX is built on a modular Linux architecture with a stateful

database, our operating system provides the following

unique capabilities:

• Easy access to all network state information allows unique

visibility and analytics

• REST APIs and Python scripting for ne-grained

programmability of network tasks

• A micro-services architecture that enables full integration

with other workow systems and services

• Continual state synchronization that provides superior

fault tolerance and high availability

KEY FEATURES

• High performance 6.4Tbps with 2,000 Mpps

• High availability with industry-leading VSX

redundancy, and redundant power supplies and fans

• Designed for core/aggregation in the campus or Top

of Rack or End of Row in the data center

• AOS-CX automation and programmability using built-

in REST APIs and Python scripts

• Advanced Layer 2/3 feature set includes BGP, OSPF,

VRF-Lite, and IPv6

• Dynamic VXLAN with BGP-EVPN for deep

segmentation in data center and campus networks

• Intelligent monitoring, visibility, and remediation

with Aruba Network Analytics Engine

• One touch deployment with the Aruba CX Mobile

App

• Aruba NetEdit support for automated conguration

and verication

• Compact 1U switch with 1/10/25GbE and

40/100GbE connectivity

• All software processes communicate with the database

rather than each other, ensuring near real-time state and

resiliency and allowing individual software modules to be

independently upgraded for higher availability

Aruba Network Analytics Engine

For enhanced visibility and troubleshooting, Aruba’s Network

Analytics Engine (NAE) automatically interrogates and

analyzes events that can impact a networks health. Advanced

telemetr y and automation provide the ability to easily identify

and troubleshoot network, system, application and security

related issues easily, through the use of python agents and

REST APIs.

DATA SHEET

ARUBA CX 8325 SWITCH SERIES

The Time Series Database (TSDB) stores conguration and

operational state data, making it available to quickly resolve

network issues. The data may also be used to analyze trends,

identify anomalies and predict future capacity requirements.

Aruba NetEdit – automated switch conguration and

management

The entire Aruba CX portfolio empowers IT teams to

orchestrate multiple switch conguration changes for

smooth end-to-end service rollouts. Aruba NetEdit

introduces automation that allows for rapid network-wide

changes, and ensures policy conformance post network

updates. Intelligent capabilities include search, edit,

validation (including conformance checking), deployment and

audit features. Capabilities include:

• Centralized conguration with validation for consistency

and compliance

• Time savings via simultaneous viewing and editing of

multiple congurations

• Customized validation tests for corporate compliance

and network design

• Automated largescale conguration deployment without

programming Network health and topology visibility via

Aruba NAE integration

Note: A separate software license is required to use Aruba

NetEdit.

Aruba CX Mobile App – unparalleled deployment

convenience

An easy to use mobile app simplies connecting and

managing Aruba CX switches for any size project. Switch

information can also be imported into Aruba NetEdit for

simplied conguration management and to continuously

validate the conformance of congurations anywhere in the

network. The Aruba CX Mobile App is available for download.

Aruba Virtual Switching Extension

The ability of AOS-CX to maintain synchronous state

across dual control planes allows a unique high availability

solution called Aruba Virtual Switching Extension (VSX).

VSX is delivered through redundancy gained by deploying

two chassis with an inter-switch link, with each chassis

maintaining its independent control.

Designed using the best features of existing HA technologies

such as Multi-chassis Link Aggregation (MC-LAG) and Virtual

Switching Framework (VSF), Aruba VSX enables a distributed

architecture that is highly available during upgrades or

control plane events. Features include:

• Continuous conguration synchronization via AOSCX

• Flexible activeactive network designs at Layers 2 and 3

• Operational simplicity and usability for easy conguration

• High availability by design during upgrades including

support for VSX Live Upgrade with LACP trac draining.
