Glossary

Plain-English definitions of the terms that show up in hardware listings, valuations, and ITAD conversations.

All-Flash Array (AFA)

A storage array populated exclusively with solid-state drives. All-flash systems hold resale value better than hybrid (flash + spinning disk) arrays because the drives dominate the system's worth.

As-Is / For-Parts

The lowest condition grade: hardware sold without testing or with known faults, priced for component recovery rather than deployment. Typically trades at 20-40% of used-working value.

Bezel

The removable front faceplate of a server. Cosmetic, but missing bezels signal careless handling and shave a few percent off resale value.

Certificate of Data Destruction

A document certifying that storage media were wiped or destroyed to a recognized standard (usually NIST 800-88). Required by most corporate buyers and all reputable ITAD vendors.

Chain of Custody

The documented trail of who possessed an asset from decommissioning through final disposition. Essential for compliance when hardware held regulated data.

Config Bucket

A valuation grouping by configuration tier — base, mid, or high — reflecting CPU class, RAM density, and storage. The same server model can differ 3-5x in value between base and high configurations.

Crypto-Erase

Sanitizing a self-encrypting drive by destroying its encryption key, rendering data unrecoverable in seconds. A NIST 800-88 recognized technique, especially practical for large storage arrays.

Dealer Retail Value

What a refurbisher charges for tested, cleaned hardware sold with a warranty — the highest of the three pricing tiers. The spread between private-sale and dealer-retail pricing pays for testing, warranty risk, and returns handling.

Decommissioning

The controlled process of retiring IT infrastructure: workload migration, power-down, de-installation, data destruction, and asset disposition (resale, redeployment, or recycling).

Drive Caddy / Tray

The carrier sled that holds a drive in a hot-swap bay. Empty bays should still include caddies — servers missing them sell for less, since genuine replacements cost $10-25 each.

e-Stewards

An electronics recycling certification emphasizing strict downstream accountability and no export of hazardous e-waste to developing countries. One of the two major ITAD certifications alongside R2v3.

iDRAC

Dell's integrated remote access controller for out-of-band server management. License tiers (Express, Enterprise, Datacenter) persist with the motherboard, and higher tiers add 5-10% to resale value.

iLO

HPE's Integrated Lights-Out management controller, equivalent to Dell's iDRAC. iLO Advanced licenses stay with the server and are a genuine resale value-add.

ITAD

IT Asset Disposition — the industry that handles retirement of corporate IT equipment: logistics, data destruction, remarketing, and recycling. ITAD vendors pay liquidation prices in exchange for handling everything.

Liquidation Value

What bulk buyers and ITAD vendors pay — typically 40-60% of open-market value. The price of speed, volume, and zero seller effort; the lowest of the three pricing tiers.

NIST 800-88

The U.S. standard for media sanitization, defining Clear, Purge, and Destroy methods. 'NIST 800-88 compliant wipe' is the phrase buyers and auditors look for on data destruction certificates.

OEM

Original Equipment Manufacturer — Dell, HPE, Lenovo, Cisco, and peers. 'OEM genuine' parts (drive trays, optics, PSUs) command premiums over third-party equivalents on the secondary market.

Out-of-Band Management

Managing a server through a dedicated controller (iDRAC, iLO, XClarity) that works even when the host OS is down. License level affects resale value.

Private Sale Value

What hardware fetches in a direct seller-to-buyer transaction (eBay, forums, brokers) — typically 70-90% of dealer retail. The middle pricing tier, and the realistic target for most individual sellers.

PoE Budget

The total power a switch can deliver over Ethernet to connected devices. A key spec for used access switches — full-power 48-port PoE+ models like 'FP' Meraki SKUs carry premiums.

R2v3

The current version of the Responsible Recycling standard for electronics recyclers and refurbishers. Selling to an R2v3-certified ITAD vendor is the standard way to satisfy e-waste compliance.

Rails / Rail Kit

The sliding brackets that mount a server in a rack. Frequently lost, annoying to replace, and worth real money: servers with rails included sell 5-10% higher.

RDIMM

Registered DIMM — the ECC server memory type used in enterprise systems. DDR4 RDIMM abundance is a major reason 14th/15th-gen platforms remain liquid on the used market.

Refurbished

Hardware tested, cleaned, updated, and typically warrantied by a dealer. Distinct from 'used': the refurbished label plus warranty is what justifies dealer-retail pricing.

Service Tag

Dell's unique per-unit identifier (HPE's equivalent is the serial number). Buyers use it to verify configuration and warranty history — listings with service-tag photos sell faster and for more.

SFP / Transceiver / Optics

Pluggable modules (SFP, SFP+, QSFP28) that give switch ports their physical interface. Often worth more sold separately than left in a switch — genuine Cisco or Arista optics are a meaningful line item.

SMART Data

Self-monitoring health statistics reported by drives, including power-on hours and reallocated sectors. Savvy used-hardware buyers ask for SMART output before purchasing systems with drives included.

Smart Licensing

Cisco's cloud-based license model. Licenses generally do not transfer with used hardware, which is why used Cisco gear is priced for hardware alone — and why buyers must budget for licensing separately.

Sweet Spot (Generation)

The used-market window where a platform is old enough to have taken its steep first-owner depreciation but new enough for current OS, firmware, and parts support. Historically two generations behind current.

Three-Tier Pricing

Silicon Value Book's pricing model: every asset carries a liquidation range, a private-sale range, and a dealer-retail range. All three are legitimate prices for the same unit in different channels.
