With the introduction of server virtualization and software defined networking (SDN), cloud service providers (CSPs) can now leverage even greater benefits from their data centers. Server virtualization technology allows dynamic provisioning of new resources on demand. During a disaster, it’s easier to move services with minimal impact on the end-user experience. Furthermore, SDN allows you to optimize resources by moving them from high-used clusters to under-used clusters. With the introduction of network virtualization, it’s easier for a data center operator to share services in a hybrid cloud environment.
It is becoming more essential to validate network performance in a lab environment, where one can easily test large-scale virtualized infrastructures. Data center integrators, NEMs, and operators also need an easier way to demonstrate and differentiate their solution from others to potential customers. One way to achieve this is to build real networks consisting of thousands of servers and millions of VMs. While this may seem like a viable choice, it may not be practical both in terms of CAPEX and/or OPEX.
Ixia RackSim is a "first-of-its-kind" test solution that emulates a virtualized data center environment with all of its complexities. The emulated hypervisors can be set up to host simulated virtual machines (VM) with all VM events, in addition to generating traffic from the simulated VM.
With RackSim, a user can verify the functionality of data center assets, test-drive massive configurations involving virtualized assets, and model a variety of environments. RackSim's functional testing scope spans the full virtual data center and cloud-based service delivery model, including:
Orchestration and management of SDN/NFV enabled networks
