MicroTCA Carrier Hub Family Supports Four Different High-Speed Fabrics

A new line of modular carrier hubs (MCHs) in the AMC/MicroTCA form factor are aimed at fulfilling the management needs of data-intensive MicroTCA applications. With GbE, sRIO, PCIe or even 10 GbE fabrics, they support four different high-speed fabric variants. The AM4904/AM4910 MCHs from Kontron come in four versions: a pure Gigabit Ethernet switching MCH, in combination with a PCIe mezzanine or with sRIO and for high-bandwidth demands, with 10 Gigabit Ethernet switching.

All versions provide central management and data switching functionality on a full-size, single-width Advanced Mezzanine Card (AMC) form factor. Equipped with a 600 MHz PowerPC 405EX processor for MCMC functionality and switching management, they enable highly efficient, redundant system architectures with up to 12 AMCs, two cooling units and four power units. With a focus on high-performance applications, Kontron’s latest MCHs are a fit for data-intensive MicroTCA-based communication applications in both telecom—including 3G, LTE and network test equipment—and non-telecom markets such as military, medical, test and measurement, as well as image and video processing applications.

To provide support for various Telco clocks, all Kontron AM4904/AM4910 MCHs feature a clock implementation and a PCI Express fabric clocking distribution. They also include high-performance features such as a wire speed, Enterprise-Class Ethernet switch with Layer 2 switching and Multi-Cast support including full 4K VLANs and link aggregation, quality-of-service support (QoS) and a packet classification engine for flexible access control lists. A full set of standard management interfaces including: a user friendly CLI, SNMP, IPMI and Web access enable easy initialization and controlling of the MCH’s switching and management functionality. External systems or shelf managers can connect to the Kontron MCHs via the Ethernet front panel ports. Special care has been taken to guarantee full support of the PICMG MicroTCA.0 standard by testing with the Polaris test suite for MicroTCA MCHs. 

The Kontron AM4904-BASE MCH provides Tongue 1 and Tongue 2 to the MicroTCA backplane. It offers a fully managed Layer 2 wire-speed Gigabit Ethernet switching functionality (Fabric [A]) including two 1000/100/10BASE-T uplink ports. 

The Kontron AM4904-PCIE extends the AM4904-BASE with an additional mezzanine for PCIe switching capabilities. It offers PCIe GEN2 Fabric (DEFG) switching functionality (x4 to 12 AMC) with support for multiple root complexes.

The Kontron AM4904-SRIO, which is also based on the AM4904-BASE, features sRIO Fabric (DEFG) switching functionality (x4 to 12 AMCs + two uplinks x4 at the front panel). 

The Kontron AM4910 comes with a fully managed Layer 2 10GbE Fabric [DEFG] and Gigabit Ethernet switching functionality. Layer 3 can be offered on a project request basis. The additional Tongues 3 and 4 connect each six 10GbE lanes plus one 10GbE update channel to the backplane.
