ODM servers: Your complete guide to ODM and white box hardware

In Q1 of 2026, servers bought directly from ODMs made up over 50% of worldwide server revenue, with hyperscale giants such as AWS and Meta choosing ODM server hardware over branded options.

This article unpacks what ODM servers are, what they mean for hyperscale data centers, and how to manage the supportability hurdles white-box infrastructure presents.

 

What is an ODM server?

ODM servers are the machines, designed and built by an original design manufacturer, that run applications and process information across a data center infrastructure.

ODMs specialize in IT hardware design, testing and manufacturing, often on behalf of original equipment manufacturers (OEMs). Their products are either sold under an OEM’s brand or bought directly by large-scale buyers, such as hyperscalers. Leading ODMs include Quanta, Wiwynn, Inventec and Foxconn.

Unlike OEM hardware, ODM servers typically don’t contain proprietary software, so customers install the operating system of their choice. This gives buyers greater control over how the hardware is configured and used.

Are white-box servers the same as ODM hardware?

Closely related to ODM infrastructure is white-box hardware. However, they are not exactly the same. White-box servers are unbranded systems assembled from a mix of standard components, rather than built to a single manufacturer’s design.

For a deeper look at how ODMs compare with OEMs and third-party maintenance providers, see our TPM vs OEM support guide.

ODM vs OEM vs white box servers: side-by-side comparison

Where do ODM, OEM and white box servers overlap and – more importantly – how do they differ? This table breaks down each server type by factors including who is responsible for the design, manufacturing and branding, as well as support and CAPEX implications.

Factor	ODM	OEM	White-box
Design	By the ODM, often to a buyer’s specification.	By the OEM or an ODM.	No single system design.
Build	Built by the ODM, often using parts from various manufacturers.	Sometimes built in-house, sometimes by ODMs or contract manufacturers.	Assembled from standard components by the buyer or an integrator.
Branded?	Sometimes, under an OEM’s brand.	Yes	No
Support	Often limited to RMAs.	Onsite support, maintenance and updates under warranty and up until EOSL.	Components may have individual support warranties, but no consolidated contract.
Customizability	High	Limited to the OEM’s standard configurations.	High
Upfront costs	Lower than OEM	High	Low, but dependent on indivdual parts costs.
Speed to deployment	Typically faster	Often weeks to months, and longer for custom configurations.	Depends on parts availability and assembly time.

 

That being said, ODMs are increasingly seeing the benefits of partnering with third-party maintenance providers such as Evernex to deliver onsite hardware support and spare-part replacements.

The ODM server market: Who buys them and why

While OEMs often sell ODM-built hardware under their own branding, businesses can also purchase ODM servers directly from the manufacturer. Hyperscalers, including AWS, Google and Microsoft, often choose this ODM-direct acquisition method to source hardware at scale and ensure that their hardware is tailored to their needs.

However, ODM hardware is no longer the exclusive domain of global hypescalers. As businesses race to keep up with technological developments while keeping CAPEX under control, ODM hardware is gaining traction across a broader range of organizations. LeanSupplAI observes that “large enterprises increasingly buy ODM for AI training clusters, and ODMs increasingly serve mid-market through reseller channels.”

Several factors are driving this shift, from hyperscalers to mid-sized companies:

Lower costs at scale

By sourcing directly from manufacturers and reducing the costs associated with traditional branding, distribution and support structures, businesses can lower their hardware acquisition costs. The larger the fleet, the more important these savings become.

Custom designs

ODMs can adapt server configurations to meet each enterprise’s requirements, including AI training, high-performance computing (HPC), cloud infrastructure and data storage. This flexibility helps businesses avoid paying for unnecessary features while optimizing hardware for their workloads.

Greater supply chain control

Buying directly from ODMs can reduce reliance on multi-step supply chains. This helps improve visibility into component sourcing and manufacturing, while reducing the potential security gaps, delays and intermediary costs implied when several parties are involved.

Why ODM hardware is harder to support

ODM servers may offer CAPEX savings and flexibility, but supporting them throughout their lifecycle can be more challenging.

Unlike established OEM support ecosystems, ODM hardware may lack the local service networks, readily available spare parts, and firmware resources needed to maintain large-scale and distributed deployments.

These gaps can make troubleshooting, repairs and ongoing maintenance more complex, time-consuming and expensive. Let’s take a closer look at ODM server supportability issues:

Parts availability

Spare components may not be readily available in local markets, particularly for less common or customized server configurations. Sourcing replacement parts internationally can extend repair times, increase shipping costs and lead to customs issues, making it more difficult to maintain sufficient spare inventory.

Firmware and software updates

Access to firmware updates, security patches and compatibility fixes can vary by manufacturer. Limited documentation or slower update cycles can complicate maintenance, increase security risks and make it harder to keep hardware aligned with evolving software environments.

Field service at scale

While OEMs and TPM providers leverage extensive networks of engineers, many ODMs have limited to no local technician coverage on their own. Businesses may need to rely on third-party service providers or develop their own maintenance capabilities to compensate. This adds operational complexity, especially across multiple locations, and can increase the TCO of hardware.

These challenges become particularly significant in AI and edge data center environments, where infrastructures are distributed across countries or continents, and hardware availability and usage make the key difference between businesses seeing a return on their infrastructure investments and experiencing the financial drain of underperforming assets.

Managing an ODM server fleet across its lifecycle: key stages

ODM server fleets often use customer-specific hardware configurations, firmware and component specifications. This creates distinct requirements from standard OEM fleets across the server lifecycle, from support and spare-parts planning to lifecycle management and decommissioning.

This table breaks down each lifecycle stage and the management processes it shoud involve:

Lifecycle stage	What happens
Deployment	Staging, validating and integrating servers into racks against hyperscaler-specific configurations and firmware baselines, rather than standard OEM SKUs. Requires repeatable processes for large-scale rollouts.
Maintenance	Specialized issue diagnosis, troubleshooting and repairs. ODM post-sale support may rely on return merchandise authorisation (RMA) processes rather than local, onsite repairs.
Sparing/parts replacement	Forecasting failures and stocking compatible components across hardware variants. ODM RMAs may take a long time to provide the part replacement if the factory is overseas, extending downtime.
Lifecycle extension	Keeping the asset active and efficient for longer through maintenance and component-replacement, reducing premature replacement and maximizing the return on investment of the server.
Decommissioning	Coordinating hardware removal, asset tracking and secure data sanitisation.
ITAD	Assessing decommissioned servers for reuse, resale or recycling, ensuring secure data destruction, documented chain of custody and responsible recovery of assets and materials.

How does server lifecycle management differ between OEMs and ODMs?

While OEMs generally offer server support services, including diagnostics, troubleshooting and maintenance, for assets covered by warranty and contract renewals, ODMs typically provide more limited post-sale support.

Often, businesses must manage installation, testing and validation independently or through a third-party service provider. Meanwhile, rather than coordinating onsite repairs, replacements and fixes, ODMs tend to offer return merchandise agreements (RMAs). This can require faulty hardware to be shipped back to the manufacturer, often overseas, for repair or replacement.

For businesses operating hundreds or thousands of servers, these delays can lead to extended downtime, expensive logistical issues and lost productivity.

How third-party maintenance supports ODM servers

Support is the clearest gap when it comes to ODM hardware offerings. However, this doesn’t mean that businesses must choose between cost-effective, customized hardware and effective maintenance. TPM is gaining significant traction amongst both hyperscale data center operators and the ODMs that supply them.

While hyperscale, AI and edge infrastructure operators benefit from the global availability, expert onsite support and SLA flexibility of third-party maintenance, ODMs are collaborating with TPM providers to leverage their existing support and logistics infrastructure, scalable processes and rapid deployment capabilities.
