1. How to choose a server for apseudo flv-mp4-streaming?

The first thing we need to decide is how we want to stream the video: with stops for buffering or without them. In the second case, you can easily calculate how many concurrent sessions will be enough on the given server bandwidth. So, we take into account the average bitrate from file properties or simply divide the file size by length and obtain an average bitrate. Dividing the speed of the link to the average bit rate we get the maximum number of simultaneous connections, when there will be no stops for buffering (comfortable viewing.) For greater accuracy, that number should be multiplied by 0.9 — 0.95, as 5-10% is overhead, which also must be considered. Suppose we have an average bitrate 400 kbit/s and 1 Gbit/s bandwidth , the result can be obtained by the formula: (1 000 000/400) * 0.9 = 2250 simultaneous viewers. Thus, knowing the traffic to the site in the peaks, we can determine which channel can hold the load, knowing that the traffic to the site during the day — is not constant, so 1 Gbit/s is enough for a site with traffic ~ 20,000 hosts per day.The second important parameter is the disk subsystem. According to our observations, to serve 1 Gbit/s traffic, when it’s not just one file cached in RAM, 6 or more HDD’s are required, a critical parameter here is the number of input-output operations per second (IOPS), one HDD simply not able to give plenty of random reads.


2. What are the server traffic restrictions?

The server has only one restriction on the traffic: the ratio of incoming to outgoing traffic should be no more than 1 to 2, that is, if there’s 1 Gbit/s outbound traffic — you get 500 Mbit/s of inbound, in theory, the 1 Gbit/s link can serve 327 TB out and 163 TB inbound traffic per month.


3. How to pay?

Invoice is sent only after successful installation and configuration for at least 1 month term.

Payment can be made by one of the methods:

-Cash in the office

-Via bank transfer

-WebMoney


4. What are the guarantees?

— signing a contract (at the office or by mail)

— seller-certificate in the WebMoney system since 2008

— involvement of a third party — the guarantor


5. Can I change the server configuration in the future?

Changing the configuration is possible, but with some limitations. Keep in mind that in the desktop processor platform is often not possible to set up more than 32 GB of RAM. Also, often more than 32 GB of RAM can be installed only on the two-processor platform. One server can be filled with up to 18 HDD.
