Swiss Facility Takes Rohde & Schwarz Storage

Broadcast and production service provider tpc Switzerland, has purchased R&S SpycerBox Cell storage and the IBM Spectrum Scale file system solutions for clients including the Swiss broadcaster SRG SSR.

The IBM Spectrum Scale file system on the R&S SpycerBox Cell and R&S SpycerBox Ultra TL has been integrated by Jordi AG at Zürich-based tpc.

tpc already has two R&S Venice ingest and playout servers in house. In the past, two four-channel R&S Venice servers generated up to 80 read/write streams in parallel to eight automated third-party transcoder systems, each with four transcoding units, all of which had to be managed. The new storage and file management solution will be added to an existing network. The network only has a limited number of ports and there is limited space in the available racks. System integrator Jordi AG came up with the solution to install two clusters – one for read and one for write – each with two R&S SpycerBox Cell units using SSDs in a RAID 6 configuration. 

IBM SpectrumScale is now used for file management. A 40GbE link using the NSD protocol serves as the backbone for each R&S SpycerBox Cell. A second 40GbE link from every R&S Spycerbox Cell combines two storage units into a SAMBA cluster and connects it to the central 40/10GbE switch. This provides the media links for the transcoder farm as well as the I/O connections for the overall system. Each R&S SpycerBox Cell uses an additional 10 GbE dual link, running NSD blocks via the central switch to the connected R&S VENICE servers. Separating the systems into input and output clusters optimizes the I/O performance for the massive data rates within each cluster. The solution fulfills all performance requirements within a single system of only four HUs.
