Dear Thomas, Michal & Tamas, Thanks for the response, Actually it is in MB/s, because to edit 2k resolution (2048 x 1152) the editor would need a throughput of around 350 MB/s, with edited file (dpx file) size around 4TB (single file). I would like to make a shared storage for 4 connected editing station. The new info reduce the need of this shared storage size (for real time editing) into 14 TB size, while I have to provide also 24-48 TB for temporary archive. I have to revise my calculation also in throughput, the total throughput needed is around 900 MB/s because usually there are 2 client editing station (autodesk lustre based on linux and davinci resolve based on mac) simultaneously edit in this throughput (2 x 350 MB/s) while the other 200 MB/s I reserve for 2 other editing station connected to this shared storage. If moosefs could not handle the function to be 'real time' editing storage, then I guess I just able to use it for the temporary archive disk which not needing so high throughput.
