HPE DL38X GEN10+ 2U SFF EI Rail KIT - P22018-B21

HPE P22018-B21 2U SFF Easy Install Rail Kit

Overview

The HPE P22018-B21 is the Easy Install (EI) rail kit designed specifically for HPE ProLiant DL38X Gen10+ servers in 2U small form factor configurations. If you're racking a DL380 Gen10+ or DL385 Gen10+ in a standard 19-inch cabinet and need slide rails that allow full server extension for maintenance access without removing the system from the rack, this is the correct part. At 9.65 lb and 34.50 inches in length, P22018-B21 is sized for deep rack cabinets and ships ready for tool-assisted installation into compatible HPE and third-party EIA-310-compliant rack enclosures.

Compatibility

This rail kit is engineered for the HPE ProLiant DL38X Gen10+ platform — specifically the DL380 Gen10+ and DL385 Gen10+ in 2U rack server deployments. The 'SFF' designation confirms fit for small form factor chassis variants; do not use with LFF (large form factor) DL38X configurations, as rail attachment points differ. Verify your specific chassis sub-model against HPE's QuickSpecs before ordering — the Gen10 (non-Plus) and Gen9 chassis use different rail attachment geometry and are not compatible with P22018-B21. Compatible with standard 19-inch EIA/IEC rack cabinets from HPE, APC, Vertiv, Middle Atlantic, and other vendors that meet EIA-310 depth requirements for a 34.5-inch rail.

Installation Notes

The 'EI' (Easy Install) designation means the rails use a tool-less or minimal-tool attachment method to the rack posts — no cage nuts or extra hardware required for standard square-hole racks; round-hole or threaded racks may need an adapter kit sold separately. The 34.50 x 6.00 x 3.30 in form factor (L x W x H) requires adequate rack depth clearance; confirm usable interior depth of your cabinet before installation. Multi-country origin (CN, CZ, JP, MX, SG, US) is standard for HPE rack accessories and does not affect fit or function.
