Why Choose This Product?

• Adds meaningful PCIe bandwidth - The x16 Gen3 interface is suited to compatible high-throughput PCIe expansion requirements.
• Two expansion positions - One riser assembly provides both x16 and x8 connectivity, increasing I/O flexibility.
• Extends existing server investment - Adds expansion capability to an installed DL180 Gen9 rather than requiring a platform replacement for PCIe capacity alone.
• HPE-specific procurement - The 725570-B21 option number provides a clear purchasing and replacement reference.
• Enterprise infrastructure fit - Suitable for data center, networking, storage, virtualization, and other server I/O expansion requirements when the installed card and server configuration are supported.
• Full-height/full-length capability - Accommodates compatible larger PCIe expansion cards.
• Configuration flexibility - The associated riser can occupy either supported riser position, subject to the second-processor requirement for secondary placement. 
• Lower migration disruption - A riser upgrade can provide additional expansion capability while retaining the existing DL180 Gen9 infrastructure, potentially reducing hardware refresh requirements.
