Detailed Specifications
HPE 682148-B21 10 Gb SFP+ FlexibleLOM Network Adapter
Overview
The HPE 682148-B21 is a single-port 10 Gigabit Ethernet adapter in FlexibleLOM form-factor designed for supported HPE ProLiant blade or rack servers. It delivers full 10 Gb throughput via an SFP+ interface and connects through a PCI Express 3.0 x8 link, making it suitable for high-bandwidth server uplinks, virtualised environments and storage-traffic offload. Because it occupies a dedicated FlexibleLOM slot rather than a standard PCIe expansion slot, it frees up those slots for other I/O and simplifies the upgrade path in dense or rack-mounted servers. It is designed to integrate with HPE server management infrastructure and supports features such as SR-IOV, link-aggregation and jumbo-frame support. Installation is straightforward in systems certified for the module, and its passive cooling profile suits chassis environments with standard airflow.
Key Features
