Custom Configurations

Built to fit. Priced to win.

Faster than new: sourced from existing supply, not built to order.2

For years, the industry has been trained on the notion of standard, off-the-shelf hardware being the fastest and cheapest way to expand capacity. No more. RackRenew brings custom server and rack configurations at the same reduced cost as commercial off-the-shelf, with very short lead times.

  • Custom server and storage solutions provide maximum flexibility
  • Hardware optimized for specific workloads and use-cases
  • Deploy servers or racks considerably faster than comparable new equipment2
  • Proven hyperscale-grade, OCP-compliant technology

Why RackRenew Custom configurations?

Every custom configuration starts from hyperscale-proven OCP hardware, then gets built specifically for your workload. Deep operational expertise delivers infrastructure optimized for your use case, not a standard shelf configuration repurposed to fit.

Lower cost without compromise

Custom does not have to mean expensive. Hardware sourced directly from hyperscale decommissions via Sims Lifecycle Services eliminates the reseller chain. Bespoke configurations match or beat commercial off-the-shelf alternatives.

Designed for demanding workloads

Standard configurations are a compromise by definition. Custom builds let you specify the exact combination of compute, memory, networking, and storage your workload actually requires, without waste where it does not.

Enterprise grade and fully validated

Every custom configuration goes through the same rigorous remanufacturing process: full hardware diagnostics, component-level testing, firmware updates, and thermal validation. Produced under the ISO 9001 and ISO 14001 certified management systems of the Sims Lifecycle Services production facilities.

Zero embodied carbon on remanufactured components

Every remanufactured component in a configuration carries zero embodied carbon3; new parts fitted for that configuration carry their original carbon. The manufacturing emissions of the original build belong to the first owner, who incurred them at first purchase. New parts added for a specific configuration, for example BMC chips or new drives, carry their original manufacturing carbon. Every bespoke rack deployed is a rack that did not need to be built from scratch.

Performance Optimization

Hardware optimized for your specific workload

Custom server configurations enable data centers to select hardware components: CPUs, GPUs, RAM, networking and storage. Specifically optimized for their workloads. By tailoring servers to specific workloads, organizations create more efficient, scalable, and reliable IT infrastructure.

  • Custom server and storage solutions provide maximum flexibility with configurations from single nodes to fully populated racks
  • Hardware optimized for specific workloads and use-cases, not a generic SKU repurposed
  • Deploy servers or racks considerably faster than comparable new equipment2
  • Proven hyperscale-grade, OCP-compliant technology originally engineered for hyperscale data centers

Lead time and availability

From scoping your project to receiving a fully built rack, faster than new procurement allows2

Rapid Deployment

RackRenew’s track record shows that remanufactured infrastructure reaches customers considerably faster than comparable new equipment, since components are sourced from existing supply rather than manufactured to order.2 Custom builds and large-volume orders follow a project timeline agreed during scoping.

Whether You Need a Balanced Rack, an HPC Cluster, or a Kubernetes Environment: RackRenew Builds to Your Spec

Whether you need a balanced compute and storage rack, an HPC-optimized cluster, or a fully configured Kubernetes environment, RackRenew builds to your specification at a cost and lead time that makes the project viable.

1  Based on RackRenew like-for-like reference comparisons of remanufactured switch, compute node, and storage node configurations against the market price of equivalent new equipment, held on file by RackRenew. Where a comparison involves a model no longer sold new, RackRenew states that in the comparison.

2  Actual lead times depend on final customer configuration, component availability and destination. RackRenew does not guarantee delivery windows on this website.

3  RackRenew assigns the embodied carbon of a component to its first owner, who incurred the manufacturing emissions at original purchase. A component that enters a second service life through remanufacture is counted at zero embodied carbon for the second owner.
