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.
