Embedded Linux® Based, Telco Tested, 1 RU, Stand Alone Multiple IP to IP Time Delay System for Multiple Video Streams in Both Standard and High Definition MPEG-2 or H.264 Streams. Standard Unit Ships with a .25 Tera Byte Intel® High End SSD. Can Time Delay Up to 40+ Separate TS or HLS IP Streams for 8 Hours. Larger SSD's Available. Managed by Remote GUI with Easy To Use Graphical Interface with Pull Downs and Recallable Config Files. Throughput: 300-400 Mbps -- Depends on Gig/E Throughput of NIC on Motherboard.
In lieu of bulky RAID systems we write to FAST AND RELIABLE Intel SSD Drives...
1. IP throughput of delay servers is about 300-400 Mbps. This is governed by the throughput of the onboard NIC card. i.e... This means we can delay about 30 10 Mbps streams or 60 5 Mbps streams. Mbps=Megabits per second.
NB. We can add 2nd NIC card to increase throughput to 700 Mbps via Gig/E.
2. Storage Time is determined by aggregate storage we provide you. If we ship with 500 GIG (bytes) SSD then you can store 10 each 50 MB (bytes) streams or 100 5 MB streams... on each drive... Keep in mind however that we are limited by I/O which limits us to bringing in 60 5 Mbps streams.
Conclusion: We need to keep both parameters in mind.

We Rely on NETWORK TIME PROTOCOL (NTP) --IMPORTANT!!!
Some People who don't trust the Internet use their own NTP servers. Here is a link to some companies who sell NTP servers.
