Stop Overpaying for IT Hardware & Services

TPM vs. OEM Support compares third-party maintenance providers with original equipment manufacturers for IT hardware support. TPM offers flexible, cost-effective services for EOL/EOSL equipment, while OEMs focus on new hardware sales, firmware updates, and standard support contracts. TPM typically saves 40-70% versus OEM support, extending hardware lifespan affordably.

What is TPM and OEM Support?

Definition of Third-Party Maintenance (TPM)

Third-Party Maintenance (TPM) is IT hardware support provided by independent service providers after the OEM ends its official support. TPM covers servers, storage, and networking equipment, focusing on extending the hardware’s useful life while significantly reducing support costs.

Definition of Original Equipment Manufacturer (OEM) Support

OEM Support refers to maintenance services offered directly by the manufacturer of your IT hardware. This includes firmware updates, hardware repairs, and technical support—but typically only during a product's active lifecycle, before it reaches End-of-Life (EOL) or End-of-Service-Life (EOSL).

Key Differences: Focus, Pricing, and Service Approach

Cons of TPM Support

Limited Access to Proprietary Firmware/Software Updates

TPM providers generally do not have access to OEM proprietary firmware or software patches. For businesses that require frequent firmware updates tied to performance or security, this can be a limitation.

🔐 Understand when OEM firmware access is critical

Requires Careful Selection of a Qualified TPM Provider

Not all TPM providers are created equal. Choosing an inexperienced vendor can lead to:

  • Slow response times
  • Limited spare parts inventory
  • Poor support quality

It's essential to vet providers with proven track records, deep multi-vendor expertise, and clear SLAs.

Not Every Business Prioritizes Extended Hardware Lifecycles

Some organizations follow strict hardware refresh cycles driven by compliance, performance, or internal IT policies. In these cases, TPM’s value proposition of extending hardware life may not align with business strategy.

However, for many data centers, maximizing ROI on existing assets remains a top priority.

Pros of OEM Support

Access to the Latest Firmware and Software Patches

OEM support provides exclusive access to proprietary firmware and software updates. These patches can be essential for:

  • Security vulnerability fixes
  • Performance enhancements
  • New feature releases specific to the hardware

For businesses with compliance mandates or specialized workloads, staying current with OEM updates is a must.

🔒 Understand how TPM and OEM updates differ

Direct Connection to Manufacturer R&D

OEM support includes a direct line to the manufacturer’s engineering and R&D teams. This connection benefits organizations needing:

  • Advanced troubleshooting for complex issues
  • Root cause analysis beyond field-level support
  • Influence on future hardware/software development

This level of insight is not typically available through TPM providers.

Integrated Support for Newly Launched Products

For the latest generation of hardware, OEM support ensures:

  • Seamless integration of new devices into existing infrastructure
  • Access to specialized setup and configuration resources
  • Early adoption of new technologies with full support backing

OEM support is ideal during the first few years of a product’s lifecycle.

Cons of OEM Support

High Maintenance Costs

OEM support contracts are known for premium pricing, especially after initial warranty periods. Businesses often face:

  • Escalating annual maintenance fees
  • Bundled services they don’t need
  • Expensive post-warranty support rates

This inflates total cost of ownership unnecessarily.

💡 See how thomastech cuts support costs 40-70%

Limited Support for EOL/EOSL Systems

Once hardware is classified as End-of-Life (EOL) or End-of-Service-Life (EOSL), OEMs typically:

  • Discontinue support contracts
  • Stop producing spare parts
  • Offer no repair services

This forces businesses to refresh hardware prematurely.

🛠️ Explore thomastech’s EOL/EOSL support solutions

Rigid SLAs and Limited Flexibility

OEMs provide standardized Service Level Agreements (SLAs) with:

  • Fixed response times
  • Limited customization options
  • One-size-fits-all support models

This lack of flexibility often mismatches business-critical needs.

⚙️ Learn how thomastech tailors SLAs for business priorities

Aggressive Push for Unnecessary Hardware Refreshes

OEMs are incentivized to sell new hardware, leading to:

  • Pressure to refresh systems still performing well
  • End-of-support declarations designed to force upgrades
  • Capital expenses that could be deferred with TPM

This creates unnecessary financial and operational strain.

Cost Comparison: TPM vs. OEM Support

Average TPM Savings (40-70% Less Than OEM)

Third-Party Maintenance (TPM) typically reduces support costs by 40-70% compared to OEM contracts. OEMs often charge premiums for post-warranty coverage, while TPM focuses on maximizing hardware life without unnecessary overhead.

💡 See thomastech’s cost-effective TPM solutions

Example Cost Scenarios for Servers, Storage, and Networking Gear

  • Servers: OEM post-warranty support might cost $5,000/year per unit. TPM reduces this to $1,500-$3,000/year.
  • Storage Arrays: OEM support for EOL arrays can exceed $50,000/year. TPM often delivers the same coverage for $15,000-$25,000/year.
  • Networking Equipment: OEM rates of $10,000/year for switches and routers drop to $3,000-$6,000/year with TPM.

These savings multiply across enterprise-scale infrastructures.

Total Cost of Ownership (TCO) Benefits of Extending Hardware Life

TPM significantly lowers TCO by:

  • Deferring capital expenses on new hardware
  • Reducing annual maintenance spend
  • Avoiding forced refresh cycles

Extending hardware usability by even 3-5 years can save businesses hundreds of thousands in both CapEx and OpEx.
