The Dell PowerEdge C6420 (multi-node), a server system designed by Dell from 2018 to 2022, weighs approximately 32 kg and is housed in a 2U rack with four nodes. This guide provides detailed instructions on the proper decommissioning of the Dell PowerEdge C6420 (multi-node) through legal and environmentally responsible methods. The process includes data destruction, decision-making between refurbishment or scrap, recovery of valuable materials during scrapping, and selecting an appropriate ITAD vendor to manage the entire lifecycle of the server unit.
LME spot ~$2.40/kg
- Copper bus bars and wiring harness: 3-5% (1.28 kg) - LME spot ~$9.50/kg
- PCB precious metals (gold-plated connectors, palladium): $5-25 per unit at integrated smelter
- Power supply transformers: small steel + copper
Real recovered value depends on smelter access and unit condition.
Step 4: ITAD vendor selection
For volumes above 5 units, use a certified ITAD vendor. Required certifications to look for:
- R2v3 (Responsible Recycling) or e-stewards for the recycler
- NAID AAA for any sub-contracted data destruction
- ISO 14001 environmental management
- WEEE-registered (EU/UK) or state EPR-registered (US)
Typical vendor decommissioning cost (per unit, including data destruction): $50-130 USD.
Major ITAD vendors:
- Iron Mountain
- Restore Datashred
- SK tes (Stanley Industrial Asset Disposition)
- Atlantix
- Sims Recycling Solutions
- Stone Group (UK)
- ERI Direct (US)
- Sage Sustainable Electronics
Compliance note
ECCN classification for export controls: nist 800-88 Purge or Destroy on internal storage; check with manufacturer for current ECCN designation if exporting refurbished units

Decommissioning is not a single step
A compliant server retirement covers six independent processes:
- Asset inventory + chain-of-custody initialisation: photo + serial + asset tag captured before any movement. Without this, downstream certifications are unverifiable.
- Data sanitisation: NIST 800-88 Purge for SSDs (cryptographic erase + cell-level verification); NIST 800-88 Clear or DoD 5220.22-M three-pass for HDDs; physical shred for failed/encrypted/regulated drives.
- License + software detachment: enterprise software (VMware, Oracle, Microsoft) often has license-per-host clauses; failure to detach before resale exposes buyer to licensing claims.
- Hardware refurbishment vs material recovery decision: working server (post-2018) has $50-$800 resale value; pre-2018 mostly material-recovery only.
- Transportation under hazwaste rules: lithium-ion batteries (BBUs, BMC modules, NVDIMM batteries) = UN3480 Class 9. Servers also classed as e-waste under EU WEEE + US state laws.
- Certificate-of-Destruction issuance: per-serial CoD required for SOC 2 + ISO 27001 + NIST 800-53 + FedRAMP audit defensibility.
Resale value matrix by server age
| Server age + condition | Resale route | Typical net value (after data destruction + transport) |
|---|
| 0-3 years, working | Direct refurbisher buyback | $400-$2,500 per 1U |
| 3-5 years, working | Broker via certified ITAD | $80-$500 per 1U |
| 5-7 years, working | Material recovery + scrap | $20-$80 per 1U |
| 7+ years OR broken | Pure scrap | $0-$30 per 1U |

Frequently asked questions
How long does a full server decommissioning project take? Single server: 5-10 business days from pickup to Certificate of Destruction. 50-server project: 15-30 business days. 500+ servers: 30-90 days depending on geographic spread + sanitisation depth.
What's the typical net cost per server? Range: -$500 (net positive due to resale) to +$200 (net cost for older + broken units). For a mixed 100-server retirement, expect break-even to modest net positive. Premium hardware (recent flash storage, GPU servers, network gear) often nets $200-$1,500 per unit positive.
Can I do data sanitisation in-house and just send empty hardware? Yes - many enterprises do this with their own NIST 800-88 toolset (Blancco, Whitecanyon, etc.). However, in-house sanitisation must still produce certificates and chain-of-custody documentation defensible at audit. Mistakes = audit findings.
