Lenovo Broadcom NetXtreme II ML2 Dual Port 10GbE SFP+ Network Adapter

Broadcom NetXtreme 10 GbE SFP+ Network Adapter Family for System x

Lenovo offers the Broadcom 10 GbE SFP+ network adapter family that is based on the Broadcom BCM57811S and BCM57810S controllers for System x® servers. These adapters use Broadcom's controller technology, which provides outstanding performance, efficiency, and scalability for the enterprise data center. The adapters connect to SFP+ Multimode Fiber SR optical modules and direct-attach copper (DAC) cables.


Did you know?

The single and dual-port Embedded Adapters (also known as mezzanine adapters) are designed specifically to fit in to a dedicated slot in servers such as the System x3650 M5. This card design allows you to use the server's standard PCIe slots for other technologies.


Features and specifications

Virtualization, cloud computing, high performance computing (HPC), and clustering initiatives are increasing workload demands. The Broadcom network adapter family is the solution of choice for workload-intensive computing environments, providing a reliable, high-performance 10 GbE connectivity solution. These adapters support PCI-SIG single root input/output virtualization (SR-IOV) and NIC partitioning (NPAR). SR-IOV delivers higher performance and lower CPU utilization with increased virtual machine (VM) scalability. QLogic NPAR enables up to four physical, switch-agnostic, switch-independent NIC partitions per adapter port. Dynamic and fine-grained bandwidth provisioning enables control of network traffic from VMs and hypervisor services.
The adapters have the following features and specifications:
-Dual-port or single-port 10 Gb Ethernet connectivity
- ASIC:
>Single port adapter: Broadcom BCM57811S controller
>Dual port adapters: Broadcom BCM57810S controller
- Choice of form factors:
>Mezzanine (Embedded) form factor adapters are supported in selected System x servers where the adapter is installed in a dedicated slot.
>ML2 (Mezzanine LOM Generation 2) adapters are supported in selected System x servers where the adapter is installed in a dedicated slot.
>The PCIe adapter is supported in a low-profile PCIe adapter slot in a wide variety of System x servers
