Chapter 34: IXIA Xcellon-Flex Load Modules

This chapter provides details about Xcellon-Flex family of load modules—specifications and features.

The Xcellon-Flex family of high speed load modules delivers high-density, high-performance test solutions. Xcellon, the architecture behind these load modules, features aggregation of multi-core CPUs and high memory to meet testing needs for high-scale performance.

The Accelerated Performance load module provides architecture for layer 2-7 performance testing, providing ultra-high-scale session and protocol emulation per port. The Full Emulation load module is for layer 2-3 mid-range protocol emulation and scale capacity testing for switches and routers. The Xcellon-Flex Combo 10/40GE Accelerated Performance load module provides both 10GE SFP+ and/or 40GE QSFP+ ports in a single chassis slot. It uses aggregation technology to combine CPU power and memory, and provides ultra-high networking protocol scalability. The 4x40GE Full Emulation load module has a rich layer 2-7 feature set and is well suited for mid-range protocol emulation and scale testing. The load module is ideal for manufacturers of large-port-count, converged data center switches.

Note: XM12 High Performance chassis is required for the simultaneous operation of 128 ports in a single chassis. If a standard XM12 chassis (941-0002) is used with these load modules, conversion to the High Performance model is required. A field replaceable power supply upgrade kit (943-0005) is available for this purpose. When one or more FlexAP10G16S or FlexFE10G16S load modules is installed in an XM12 High Performance chassis, the maximum total number of load modules that may be installed at one time in a single chassis is 8. The XM2 portable chassis (941-0003) supports up to 16 ports (1 load module) of the FlexAP10G16S FlexFE10G16S modules. No other load module is installed in the XM2 chassis when a FlexAP10G16S or FlexFE10G16S load module is installed.
