HPE DL380 GEN10+ 3P X8 Slimsas Prim KIT - P27091-B21

HPE P27091-B21 ProLiant DL380 Gen10+ 3-Port x8 SlimSAS Primary Cable Kit

Overview

The HPE P27091-B21 is a three-port x8 SlimSAS primary cable kit engineered for the ProLiant DL380 Gen10+ server platform. It provides the internal storage interconnect path between the system board and drive backplanes, enabling high-density SAS/SATA drive configurations where the onboard cabling is absent or needs expansion. If you're populating additional drive bays on a DL380 Gen10+ and the factory cable set doesn't reach your backplane configuration, P27091-B21 fills that gap without requiring a third-party workaround.

Compatibility

Designed and validated for the HPE ProLiant DL380 Gen10+ (DL380 G10+) server platform. The x8 SlimSAS interface mates with HPE's Gen10+ SAS expander and drive backplane connectors. This kit is not interchangeable with DL380 Gen10 (non-Plus) or other ProLiant generations — connector keying and backplane pinouts differ across generations. Confirm your chassis is specifically the DL380 Gen10+ before ordering; the Gen10 and Gen10+ share a similar chassis form factor but use distinct internal cable assemblies.

Installation Notes

Route cables according to HPE's internal cabling guide for the DL380 Gen10+ — incorrect routing can obstruct airflow across the drive cage and degrade thermal performance under sustained I/O load. SlimSAS connectors are keyed but fragile under lateral stress; seat each connector straight-on and confirm the latch clicks before powering the system. Weight is 0.45 lb, so the assembly is light enough for single-technician installation without strain-relief tooling, but verify cable management arms are clear before final dressing.
