Huawei will showcase its CloudEngine 12800 line of core switches, which feature a switching capacity of up to 48Tbps and bandwidth of 2Tbps per slot, Huawei says. The CloudEngine 12800 and the CloudEngine 5800/6800 top-of-rack switches support connectivity for Gigabit Ethernet, 10G Ethernet, and 40/100G Ethernet, as well as features for network virtualization and computing, storage and network convergence.

The CloudEngine 12800 series consists of three chassis-based platforms with four-, eight- and 12-I/O slots, and two slots for main processing units. On the rear side of the switch are slots for six fabric modules -- five primary, plus one for redundancy.
The line is based on a non-blocking CLOS fabric architecture, and features front-to-rear ventilation to improve heat dissipation. The high-end CloudEngine 12812 will support up to 96 100G Ethernet ports, 288 40G Ethernet ports and 1,152 10G Ethernet ports.
For network virtualization, the CloudEngine 12800 series incorporates Huawei's Cluster Switch System (CSS) feature to virtualize multiple switches into one logical switch. It also includes a feature called Virtual System (VS) to virtualize one switch into multiple independent logical devices.
Together, CSS and VS are designed to turn the network into a resource pool so that network resources can be allocated on demand.
The CloudEngine series also supports TRILL, the IETF specification for multipath Ethernet forwarding in data center and cloud fabric architectures, and will likely support other fabric architectures as well. With TRILL, network administrators can use CloudEngine switches to build large-scale Layer 2 networks with over 500 nodes, Huawei says.
