HPE 872257-B21 DL560 Gen10 2-Processor Slimline Riser
Overview
The 872257-B21 is a slimline PCIe riser assembly designed for the HPE ProLiant DL560 Gen10 server in dual-processor (2P) configurations. If you're expanding I/O capacity on a DL560 Gen10 — adding a network adapter, storage controller, or similar slimline half-height card — this riser provides the physical slot and signal path to make that expansion possible without modifying the chassis. At 1.81 lb, it installs directly into the designated riser bay on the DL560 Gen10 motherboard tray, keeping the build clean and within HPE's supported hardware matrix.
Compatibility
Designed specifically for the HPE ProLiant DL560 Gen10 in 2-processor configurations. This riser is not interchangeable with single-processor DL560 Gen10 builds, nor with DL560 Gen9 or other ProLiant families (DL380, DL360, DL580). Verify your server's processor population and existing riser bay assignments before ordering — HPE's DL560 Gen10 Quick Specs document confirms which riser slot this unit occupies relative to the 2P board layout. If you are configuring a 1P system or need a different slot position, cross-reference the HPE DL560 Gen10 riser options in HPE's server options guide to confirm the correct part number for your expansion scenario.
