ExtremeXOS is a highly available and extensible foundation for converged networks. ExtremeXOS raises the bar for availability, critical for offering carrier-grade voice and video services over IP and to support mission-critical business applications such as CRM. A more available network can also help to lower operational costs by drastically reducing emergency maintenance.
ExtremeXOS allows you to extend the capabilities of your network. It allows you to integrate specialized application appliances such as security devices into your network. ExtremeXOS has been designed from the ground up to support the next-generation Internet Protocol, IPv6. Even if you are not planning to use IPv6 immediately, ExtremeXOS will secure the network using IPv6 Access Control Lists and provide investment protection for your network.
Security capabilities provide network access control integrated with endpoint integrity checking, and network control and management plane protection. Its innovative universal port framework provides dynamic security policies for users as well as auto-configuration of ports and VoIP phones.
High availability architecture
ExtremeXOS creates a highly available network for voice services and other mission-critical business applications. Preemptive multitasking and protected memory allow each of many processes - such as resiliency or device management protocols - to run as separate Operating System (OS) processes that are protected from each other. With process monitoring and restart, ExtremeXOS dramatically increases network availability. Each independent OS process is monitored in real time. If a process becomes unresponsive, actions can be taken such as hitless failover or automatic process restart.
ExtremeXOS allows for flexible expansion of network capabilities by providing a means for third-party applications in the network to interact directly with the OS. If you need to extend your network to handle other applications or integrate monitoring software or security devices, ExtremeXOS integrates best-of-breed solutions with an open yet secure XMLbased API. For example, this extensibility allows integration with third-party applications such as security appliances, service provisioning software, and VoIP monitoring solutions to provide a closed loop for new monitoring and response capabilities. It also serves as a framework for integration with management software such as service provisioning solutions.
ExtremeXOS guards access to the network through authentication, host integrity checking and dynamic user/time/location-based security policies. It hardens the network infrastructure with Denial of Service (Dos) protection and IP security to protect the infrastructure, network services, applications and client devices/computers from man-in-the-middle attacks and eavesdropping. It also provides a full suite of secure management protocols using authentication and encryption, ensuring continued control over your infrastructure.
Data centerProduct Highlights
Data center managers face unique challenges, such as virtual machine mobility and security. ExtremeXOS supports multiple capabilities and features to support this ever-evolving environment. ExtremeXOS also supports Direct Attach, which eliminates the virtual switch layer, simplifying the network and improving performance. Direct Attach enables data center simplification by reducing network tiers from 4 or 5 tiers to just 3 or 2 tiers, depending on the size of the data center.
