Technical Implementation

In the case of the Luneta project, the uninterrupted, real-time transmission of sounds and images with a minimum of latency is so complex that conventional media technology methods would be either insufficient or involve a disproportionate level of technical expenditure.

For this reason, Hewlett Packard Enterprise – the tech partner on this project – is using a fresh and innovative new approach to the transmission of sound and image data. First of all, the Proliant servers used in the mirrored Luneta structure are equipped with very powerful Intel® processors that enable virtualisation; secondly, the servers contain multiple high-performance graphic cards (NVIDIA GPUs) to allow for particularly rapid video processing. The use of ESXi Hypervisor created by the company VMWare gives virtual graphic computers direct access to GPU hardware. The advantage of virtualisation is its deployment of several virtual machines on one physical computer, which enables the problem-free parallel processing of different tasks, including IT core services and different applications for audio and video processing. The use of the efficient H.264 – Videocodec makes it possible to generate a high-definition, video-optimised transmission that nevertheless requires a lower bandwidth with broad software support. With the help of specially configured virtual machines, it is also relatively easy to pre-programme a wide variety of scenarios and control them via HP Tablet.

With this innovative technical solution, Hewlett Packard Enterprise shows that even highly demanding media-tech scenarios such as these can be mastered using reliable, modern and standardised IT systems. Very few components are required in each of the “domes”, and the HPE Aruba network connects the components both via LAN and WLAN technology.

The core services (e.g. Active Directory, DNS, file services, and many more) required for this project are made available by Windows server operating systems, much like in regular data centres. The streaming applications are found on virtualised standard windows and Linux-based machines, which gives the solution a high degree of flexibility.
