Calabasas-based Ixia, the developer of IP network testing equipment, reported Monday that its products were selected for testing efforts at Dell. Ixia said Dell is using its IxLoad products to test its PowerEdge server line, for performance and virtualized server testing. Financial impact of the win was not disclosed. Ixia said it was selected to test large rack servers, because it is able to emulate millions of subscribers interacting with Internet and enterprise services. Ixia's various software and hardware products are used for testing of network devices.
