HPE DL380 G10+ 4P Slimsas SEC Riser KIT - P35417-B21

HPE P35417-B21 ProLiant DL380 Gen10 Plus 4-Port SlimSAS Secondary Riser Kit

Overview

The P35417-B21 is a secondary riser kit designed for the HPE ProLiant DL380 Gen10 Plus server platform, providing four SlimSAS (SFF-8654) connections to expand SAS or NVMe storage connectivity beyond the primary riser's capacity. If you're building out a high-density storage configuration on a DL380 Gen10 Plus — think all-flash arrays, mixed NVMe/SAS tiering, or surveillance NVR backbones requiring large drive counts — this riser is the internal upgrade that makes the additional drive bays addressable. The kit ships at 1.81 lb, consistent with a populated bracket assembly rather than a bare card.

Compatibility

Engineered specifically for the HPE ProLiant DL380 Gen10 Plus (G10+) platform. The SlimSAS interface (SFF-8654) is not backward-compatible with legacy SAS connectors or earlier Gen10 (non-Plus) DL380 variants — confirm your chassis generation before ordering. This riser targets the secondary riser slot on the DL380 Gen10 Plus; it is not a drop-in for the DL360, DL560, or other ProLiant families. Pair with compatible network video recorders or storage-dense server builds where additional SAS or NVMe drives need to be addressed through the secondary slot.

Installation Notes

Installation is performed with the server powered down and chassis cover removed. The riser seats into the designated secondary riser slot on the DL380 Gen10 Plus system board — no tools beyond standard server deployment practice are required for the riser itself, though drive cabling to the SlimSAS ports will depend on your backplane configuration. Verify HPE's server accessory compatibility matrix for your specific DL380 Gen10 Plus build (CPU count, backplane type) before commissioning, as some configurations restrict secondary riser options. Country of origin varies (BR, CN, CZ, JP, MX, SG, US) — factory-new, genuine HPE hardware.
