HPE DL580 GEN10 2X 4P Slimline Riser KIT - 878360-B21

HPE 878360-B21 DL580 Gen10 2x 4-Port Slimline Riser Kit

Overview

The HPE 878360-B21 is a dual-riser expansion kit engineered for the HPE ProLiant DL580 Gen10 server platform. It provides two 4-port Slimline riser assemblies, enabling additional PCIe card population in high-density compute configurations where maximizing I/O slot count is a hard requirement — storage HBAs, 25GbE NICs, accelerators, or additional RAID controllers. Weighing 2.27 lb, the kit ships as a matched pair factory-configured for the DL580 Gen10 chassis geometry; swapping in a mismatched riser from another ProLiant generation risks physical incompatibility and voided support. If your DL580 Gen10 build is hitting PCIe slot limits on a storage-heavy or network-intensive workload, the 878360-B21 is the correct expansion path.

Compatibility

Designed specifically for the HPE ProLiant DL580 Gen10 platform. The Slimline riser connector standard is generation-specific — this kit is not interchangeable with DL580 Gen9 or earlier chassis, nor with other ProLiant families such as the DL560 or DL580 Gen8. Verify your chassis part number against HPE's QuickSpecs for the DL580 Gen10 before ordering. This kit carries PCIe riser and expansion card UNSPSC classification 43211600, consistent with server I/O infrastructure components. For builds requiring additional HPE ProLiant server accessories such as drive cages, power supplies, or cable kits, confirm slot assignments in the DL580 Gen10 server maintenance guide prior to installation.
