Stop Overpaying for IT Hardware & Services

Third-Party Maintenance works by providing expert hardware support for servers, storage, and networking equipment after OEM warranties expire. It extends hardware life, reduces costs, and ensures uptime through proactive monitoring, flexible SLAs, and rapid parts replacement. TPM is ideal for maintaining End-of-Life (EOL) and End-of-Service-Life (EOSL) systems.

What is Third-Party Maintenance (TPM)?

Quick Refresher on TPM Definition

Third-Party Maintenance (TPM) is hardware support provided by specialized companies after the Original Equipment Manufacturer (OEM) ends its official support. TPM covers servers, storage systems, and networking equipment, ensuring critical infrastructure stays operational, secure, and cost-efficient—long past OEM “end-of-life” declarations.

Why TPM is the Smart Alternative to OEM Support

  • Massive Cost Savings: Typically 40-70% less than OEM support contracts.
  • No Forced Hardware Refreshes: Extend the life of perfectly good equipment.
  • Customizable SLAs: Support agreements tailored to your actual business needs, not the OEM’s sales agenda.
  • Multi-Vendor Support: Manage all your hardware (Dell, HP, IBM, Hitachi, Cisco, etc.) under one contract.

Ideal for EOL/EOSL Hardware Needing Reliable, Affordable Maintenance

When OEMs declare your hardware End-of-Life (EOL) or End-of-Service-Life (EOSL), they stop offering support. However, that hardware might still be mission-critical. TPM ensures:

  • Continued reliability and performance
  • Access to replacement parts and expert repairs
  • Compliance with security and operational standards

Step 1: Asset Discovery & Assessment

Full Inventory Audit of Servers, Storage, and Network Gear

The first step in Third-Party Maintenance (TPM) is a detailed hardware audit. This involves cataloging all active equipment in your data center, including:

  • Servers (Dell, HP, IBM, Hitachi)
  • Storage systems (SAN, NAS, VSP, NetApp)
  • Networking equipment (Cisco, Brocade, Juniper)

Every device's model, serial number, configuration, and current support status is documented.

Identifying Coverage Gaps, EOL Risks, and Support Needs

After the inventory is complete, thomastech identifies:

  • Unsupported devices no longer covered by OEM
  • EOL/EOSL risks where OEM support is ending soon
  • Critical systems requiring high-priority maintenance
  • Opportunities to consolidate support for multi-vendor environments

This step ensures nothing falls through the cracks.

Creating a Comprehensive Asset Database

The collected data is organized into a comprehensive asset database, serving as the foundation for:

  • Custom Service Level Agreements (SLAs)
  • Proactive maintenance schedules
  • Parts planning and stocking strategies

This database allows thomastech to deliver faster support, reduce downtime, and extend hardware life.

Step 2: Customized Service Level Agreements (SLAs)

Defining Response Times, Coverage Hours, and Critical Systems

Customized SLAs begin by defining:

  • Response Times: Options like 4-hour on-site response, next-business-day support, or remote troubleshooting.
  • Coverage Hours: 24/7/365 support, business hours only, or hybrid models.
  • Critical Systems Prioritization: Identifying which servers, storage, and network devices require high-priority support.

Every SLA is aligned with your operational needs, not a generic OEM standard.

Flexible SLAs Tailored to Business Priorities

thomastech understands that not every device requires the same level of urgency. SLAs are tailored to:

  • Critical production systems needing immediate attention.
  • Non-critical assets that can operate with slower response times.
  • Budget optimization by allocating resources where they matter most.

This flexibility ensures maximum uptime while managing costs effectively.

Next Steps

Frequently asked questions: How Third-Party Maintenance Works

What are the initial steps in a TPM engagement?

First, the provider conducts an asset audit to inventory hardware, assesses current SLAs, then proposes a customized maintenance plan including coverage levels, response times, and pricing.

How does asset data transfer and onboarding occur?

After agreement, asset records are uploaded into the TPM portal, tags are affixed to equipment, and technicians verify serials and configurations to sync the provider’s system with your inventory.

How are replacement parts sourced and stocked?

TPM providers maintain global depots with certified spare parts, including end-of-life components, and use demand forecasting to pre-position inventory near your sites for rapid dispatch.

What happens when a hardware failure occurs?

You log a ticket via portal or phone, the SLA clock starts, and the nearest field engineer is dispatched with the required part to perform on-site repair or replace the failed module.

How is ongoing performance tracked?

Providers deliver regular reports on ticket volumes, response/repair times, part usage, and uptime metrics, and hold periodic reviews to adjust SLAs and optimize support processes.
