RAID Controller Cache and Battery Procurement Checklist

Procurement note: Representative examples support identification and procurement planning. Final model, condition, compatibility, evidence, availability, and quotation remain order-specific.

SECTION 01

Decision summary

Identify the controller first, then match the documented cache-protection design, battery or energy-pack part number, cable, carrier, firmware and server platform. Ask for order-specific evidence of the quoted components; a battery label or connector shape alone does not prove compatibility or usable condition.

• Exact controller identity
• Cache-protection architecture
• Battery or energy-pack part number
• Platform and evidence scope

SECTION 02

Separate cache policy from the protection component

Record the required controller behavior and the documented protection hardware as separate fields. Dell describes non-volatile cache preservation for covered PERC controllers, but the applicable cache behavior and hardware must be checked against the exact controller rather than generalized across families.

• Controller cache capability
• Required write policy
• Documented protection method
• Exact firmware context

SECTION 03

Match battery, energy pack, cable and carrier

Capture readable labels for the controller and protection component, plus the interconnect cable, mounting carrier and server model. HPE installation material provides a platform-specific example of controller cabling and an energy-pack connection, reinforcing that these parts belong to a documented assembly.

• Battery or energy-pack label
• Cable and connector
• Mounting carrier
• Server model and location

SECTION 04

Define condition evidence without inventing health

For used or pulled parts, state which visual, diagnostic or controller-status evidence is required and whether it applies to every unit or a sample. Do not treat the presence of a battery, a printed rating or a clean photograph as proof of remaining life or a completed functional test.

• Readable component labels
• Visual-condition scope
• Requested status output
• Unit or sample coverage

SECTION 05

Plan replacement and service boundaries

State whether the RFQ is for a complete controller assembly, a replacement protection component or a spare kit. Record any installation, configuration and service boundaries separately, because sourcing an exact part does not by itself validate an operating-system change or live array procedure.

• Complete assembly or component
• Replacement or spare purpose
• Installation responsibility
• Configuration and recovery boundary

SECTION 06

RFQ checklist

Send the controller and server model or part number, quantity, cache requirement, battery or energy-pack identifier, cable and carrier details, firmware context, target condition, destination and requested label, visual or status evidence. Final availability, condition, test scope, packing, and quotation are confirmed per order.

• Controller, platform and quantity
• Cache and protection component
• Cable, carrier and firmware
• Condition, evidence and destination
