Stop Overpaying for IT Hardware & Services

Third-Party Maintenance (TPM) is a cost-effective alternative to OEM support for IT hardware like servers, storage, and networking equipment. TPM providers extend hardware life beyond OEM end-of-support, offering flexible SLAs, expert repairs, and proactive maintenance—typically saving businesses 40-70% compared to OEM contracts. Ideal for EOL/EOSL systems.

Understanding Third-Party Maintenance (TPM)

Simple Definition of TPM

Third-Party Maintenance (TPM) is hardware support provided by independent companies after the Original Equipment Manufacturer (OEM) stops supporting a product. TPM covers servers, storage, and networking equipment, keeping critical infrastructure running smoothly—without the sky-high OEM price tags.

How TPM Differs from OEM Support

OEM SupportThird-Party Maintenance (TPM)

Focused on selling new hardware Focused on extending hardware lifespan

High-cost, rigid support contracts Flexible, affordable service agreements

Stops support at EOL/EOSL Supports EOL/EOSL hardware for years

Limited to their own brand Multi-vendor, multi-generational coverage

Standard SLAs with little flexibility Customizable SLAs tailored to business needs

Why TPM Exists: Supporting EOL/EOSL Hardware When OEMs Won’t

When hardware reaches End-of-Life (EOL) or End-of-Service-Life (EOSL), OEMs prioritize pushing new sales, leaving companies stranded with critical systems still in production. TPM exists to fill this gap—offering expert maintenance, spare parts, and proactive support to keep legacy equipment reliable and secure.

TPM empowers businesses to:

  • Avoid premature hardware refreshes
  • Reduce maintenance costs by 40-70%
  • Maintain operational stability without OEM lock-in

Is TPM Right for Your Business?

Do You Have EOL/EOSL Hardware Still in Production?

If your data center runs servers, storage, or networking gear that OEMs have declared End-of-Life (EOL) or End-of-Service-Life (EOSL), you’re a prime candidate for TPM. Rather than retiring perfectly functional hardware, TPM keeps it operational, secure, and compliant.

Are You Seeking Cost-Effective Alternatives to OEM Support?

OEM maintenance contracts are notoriously expensive, especially for legacy systems. TPM typically offers 40-70% savings compared to OEM support, delivering enterprise-grade service without the inflated price.

Is Vendor Lock-In Limiting Your IT Strategy?

OEMs often tie you into rigid contracts with limited flexibility. TPM frees you from vendor lock-in by supporting multi-vendor environments, giving you control over your IT roadmap—not the manufacturer’s sales cycle.
