End of Life (EOL) vs. End of Service Life (EOSL) Tip Sheet

Know what your options are when your data center server, storage or network equipment approaches End of Life (EOL) or End of Service Life (EOSL). 

These terms do not accurately speak for equipment performance. The OEM industry uses these labels to indicate an equipment lifecycle phase as it relates specifically to OEM support, marketing, development, etc.

Your devices continue functioning well after an EOL/EOSL date, despite what mayhem awaits you according to the original equipment manufacturer (OEM). You don’t need to pull the plug on your hardware because you have the option to extend the life of your equipment and save money along the way using third-party maintenance (TPM) coverage.

EOL | EOSL | EOD Timeline

What is End of Life?

End of Life (EOL) means the OEM will no longer market, sell, or update your equipment after a certain date. These dates are determined by Dell, IBM, HPE, etc. and go into effect at different times depending on the system.

End of Life may also be referred to as
End of Sale.


What is End of Development?

End of Development (EOD) is when the OEM ends production of the equipment’s operating system – meaning software updates and patches are no longer released. At this time, equipment may have limited post-warranty OEM support options.


What is End of Service Life?

End of Service Life (EOSL) or End of Support Life are phrases OEMs use to indicate the ending of services and updates for server, storage and network equipment. At this point, the OEM no longer sells, provides updates, or renews support contracts on these systems.

End of Service Life may also be referred to as End of Support.

What does EOL or EOSL mean for my data center?

These OEM-designated stages mean a parting of ways between your equipment and the full support of the OEM. The good news for you is that you have additional support options. EOL and EOSL stages can be your signal that you can significantly reduce support costs as you extend the life of your working equipment. TPM providers can continue to provide experienced support for you through access to most OEM equipment updates, parts and more.

Does the OEM support my EOL or EOSL Equipment?

In certain cases, the OEM will continue to provide support. However, the coverage may offer limited support services and increased pricing as time goes on. It’s important to note that these support costs are typically inflated.


Per Gartner, "Customers of all sizes, all geographies and all verticals are using TPMs for some postwarranty and EOSL devices."

Do I need to refresh my EOL or EOSL equipment?

If you find yourself being directed to a new purchase or expensive post-warranty support, take a moment to review your immediate and future data center needs. You can extend the life of your EOL and EOSL equipment while capturing major savings with the help of third-party maintenance. Server, storage and network parts are available long after the OEM turns off the light for most equipment. TPM providers have access to high-quality OEM parts from trusted channels to maintain the full functionality of your EOL and EOSL equipment.

How do I find EOL and EOSL dates?

In some cases, the OEM will announce a product’s End of Life and End of Service Life dates. But it’s easy to overlook or lose track of those dates. Find accurate EOL and EOSL dates across multiple vendors by searching our online database!

A change is needed. When replacing your EOL or EOSL assets is the right decision for your data center, make sure you’re prepared for the time and costs that accompany a hardware refresh.

You may need to take on the time and cost of a hardware refresh. Key factors that should help you determine if an upgrade is necessary include software compatibility, hardware computability between devices and if your performance capacity has been exceeded. If your equipment is meeting your immediate needs, delaying your refresh can improve the value of your original investment.  

You can rely on your EOL and EOSL equipment performance and lower the support costs with third-party maintenance. Third-party maintenance is your OEM support alternative for your data center hardware/infrastructure/environment.
