Extreme Integrated Application Hosting

Extreme Integrated Application Hosting (IAH) architecture provides a flexible and open solution that enables organizations to deploy high-performance and flexible visibility applications pervasively throughout their network for improved monitoring and troubleshooting. Enabled by VOSS, this preconfigured Quick Emulator (QEMU) Kernel-based Virtual Machine (KVM) environment leverages high performance x86 CPUs to host these applications, extending visibility customized to the business and operational needs of the organization across the entire network.

The QEMU KVM environment supports several pretested and well-known packet capture applications in a Linux virtual machine, including Wireshark and tcpdump. There are a wide variety of additional applications, tools, and utilities that organizations are able to run in this environment, such as data analytics applications, packet generators, monitoring tools, troubleshooting utilities, and many others. While the QEMU KVM environment is open and can host any application, it is designed and ideally suited for networking applications, tools, and utilities.

IAH architecture supports the creation and use of virtualization domains, such as virtual machines, and Docker containers. This design creates a common-use host, which coordinates and automates multiple guest-networking functions into chains. The hardware boots into the virtual Linux OS, providing the ability to run additional applications or services within a specific virtual machine or a Docker container, and simultaneously supporting the regular functionality of the switch.

Yet Another Next Generation (YANG) model is used to manage configuration and retrieve operational data. You access the YANG model through Representational State Transfer Configuration Protocol (RESTCONF) using a northbound interface, namely Extreme Management Center or ExtremeCloud IQ - Site Engine, that provides an additional way to configure and monitor the switch. For more information on RESTCONF, see Representational State Transfer Configuration Protocol (RESTCONF) Fundamentals.

Virtual Services Resources

The virtual services resources are isolated from each other, as well as from the Network Operating System (NOS) running the switch.

The resources available for all virtual services on VSP 7400 Series switches are as follows:

The resources available for all virtual services on VSP 4900 Series switches are as follows:

Note

You must install a modular SSD unit to use virtual services on VSP 4900 Series switches.

The switch OS uses the following resources on VSP 7400 Series and VSP 4900 Series:
