6850 is 8th generation circa 2006, intel 8501 chipset, xeon 7100 processor

r520 is 12th generation circa 2012, details unclear, probably intel c600 chipset, xeon e5-2600

r710 is 11th generation circa 2009, intel 5520 chipset, xeon 5500/5600

r900 is 10th generation circa 2008, intel 7300 chipset, xeon 7200/7300/7400

Dell does not warranty any system past 7 years.  Any system out of warranty is for all particle purposes EOL.  Parts are provided for out of warranty systems if still available but one should not assume availability of parts for a system that is out of warranty. 

If you have the service tag from each system you can visit support.dell.com and look up the systems original configuration, date built, and the warranty status.  You can also find the drivers and manuals for the system there.

It depends on what you mean by EOL. End of sales? Phone support? Service/repair? Replacement parts and upgrades? Driver/firmware maintenance? There is no defined timeframe and it depends on many factors. Warranty is not available for 7 years on all machines. Most have the option of 5 years, but only mainstream models get extensions to beyond 5 years, as there is usually a significant number of parts available to service those models, and sometimes extensions beyond 5 years are only for specific groups (government, etc.).

It depends. What is your desired definition of End-of-Life? What exactly are you looking for? Depending on how you define EOL, they could all be. For most definitions though and for most intents and purposes, they probably all are except the R520 and R710.

I want just which of following model is END of generation and no safe for continue as long.

It still don't understand what you are asking for. NONE of these servers are currently shipping servers, meaning you cannot buy a new one from Dell.

If you want to renew/extend the warranty or support, you probably only can on the R710 (depending on when it was purchased - it was first released in late 2009) and R520.

If you want to purchase replacement parts through Dell's spare parts, they likely stock "all" parts only for the R710 and R520, and they probably have "some" parts for the R900 and x950. They are unlikely to have anything for a 6850. All spare parts can be purchased through third-party suppliers though.

Firmware is no longer being developed for the 1950, 2950, 6850, and R900. The R710 is probably finished as well. The R520 will likely have increasingly infrequent ongoing hardware development over the next year or so.

Drivers are typically developed as newer OS's are released based on the requirements of the OS, as well as compatibility issues. For example, 2012 is not supported on your 6850 - it may work anyway, but Dell did not develop drivers for it. 2012 R2 is fully supported on the 2950 (some features are not supported), and it is likely that 2016 will also be supported, but we won't know until the OS is released and Dell can test/validate it (or not).

In short, there is no defined EOL.

I answered this question in great detail.

TheFlash echoed my respond two more times.

The original poster should try reading all the clear information that was presented to him/her that has answered the question at least three times.

It would also be nice if he/her showed some appreciation for the help given.
