Dell PowerEdge Servers EOL

To the best of my knowledge, there are no set in stone EOL dates. If your concern is making sure parts will be available, that's something covered by the warranty. Generally speaking, the servers carry up to a 5 year warranty, though there are some exceptions to that allowing for 2 year extensions to 7 years.

I'll certainly look around to double check this, but I'm not aware of anything having been published.

He likely won't find anything, as they don't publish that. What exactly are you looking for, sales? tech support? parts? They will support your machine for as long as you have support on it. Need it covered/supported, purchase the coverage now. 5 years max, occasionally extended to 7 depending on the model, ubiquity, replacement, etc. Sales ... they will start selling it's replacement usually within 2 years (no set time/date), but sales will continue until stock is depleted (again, no set date). Parts ... until they are gone; more popular/ubiquitous models will have greater stock levels and longer production timeframe.

Even once Dell stops stocking parts through their APOS, they are easy enough to find through suppliers.

Flash is correct on both counts. These sorts of dates have never been something we've had published and I didn't find anything to run counter to that. However, I prefer to take a fresh look every time the question is asked. Never know if I might have missed a communication about a change.

I'd also parrot his sentiment on asking about the underlying cause for concern. For what it's worth, I'm still able to source parts for my R710 without issue.

Thank you for the response.

The underlying need is to understand how long before i need to think on replacing the server. Like R230 which is old. I now understand it maybe 5 years  from date of purchase and upto 7 years. 

My question is after 7 years , will i get warranty or do i need to make the mandate switch to newer HW.

i am big on getting parts as this is production equipment and i dont want to rely on external market on the chance they might or might not have spare parts for a 7 year old server.

Don't leave it up to Dell. Make an internal decision and policy - with accompanying budget - on how long YOUR server and computer lifecycle will be, whether it's ok to run them out of support, and how much will be spent on the warranty coverage (above and beyond the cost of the hardware and software you actually NEED). This represents proper management of organizational infrastructure, and both you as IT (?) and company management, including financial, shares in the responsibility to maintain and invest in critical infrastructure.

If you aren't able to properly support and troubleshoot issues on the servers or are running a standalone mission-critical machine (meaning no cluster/failover, etc.), then they should always have a support contract attached to them, even if that means you have to replace them every 5 years to maintain that support. 

Suppliers are often MORE reliable than Dell for sourcing parts, particularly the older the system gets, as Dell's after-market products stock shrinks to support ONLY warrantied systems and parts.
