Basic Edition CloudMCU server supports: 1000 channels of voice ports; 400 channels of voice & data conference port; 100 channels of SD AVC; 50 channels of 720p30 AVC; 25 channels of 1080P30 AVC; 12 channels of 1080P60 AVC.

Technical Deep Dive

Huawei CloudMCU Basic Edition on a 2288X V5 server with two Intel Xeon Silver 4214 12-core processors supports 12 concurrent 1080p60 AVC transcoding channels. The provided configuration has 24 physical CPU cores, eight 16 GB memory modules for 128 GB RAM, and two 600 GB disks. The MCU's media-processing limit is defined by the approved hardware and software profile, not simply by equating CPU cores with video ports.

Video transcoding can require incoming streams to be decoded, processed, and re-encoded for different endpoint capabilities. At 60 frames per second, the workload is greater than at 30 frames per second for comparable resolutions and codecs. Accordingly, the Basic Edition supports 12 1080p60 channels versus 25 1080p30 channels. SVC forwarding and voice-only port capacities must be considered separately. This distinction prevents capacity errors when designing high-definition multipoint conferences. The correct answer for the exact stated server configuration is 12, option B.

For presales sizing, the selected signaling platform, media-processing engine, endpoint population and expected peak conference concurrency must be dimensioned independently. Huawei SMC performs centralized administration, Switch Center provides registration and call control, and the MCU supplies the media services needed for multipoint conferencing. The selected software release, server model, licenses and applicable endpoint capabilities determine the actual production limit.
