WHY CHOOSE THIS PRODUCT?

• The 870548-B21 is a practical choice when a compatible HPE DL Gen10 server needs additional PCIe expansion without replacing the server. Its x8/x16/x8 layout offers more flexible card deployment than GPU-focused alternatives, while supporting full-height card formats. Buyers should verify the exact server model, riser location and processor configuration before procurement; on supported DL380 Gen10 configurations, the secondary riser requires Processor 2.
