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.
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
SFP+ port supporting fiber optic and direct-attach copper (DAC) cables PCI Express 2.0 x8 host interface (5 GTps) Full line-rate performance Ethernet frame: 1500 byte or 9600 byte (jumbo frame) VLAN support with VLAN tagging Supports Switch-independent NIC partitioning (NPAR) with up to four partition assignments per 10GbE link Supports SR-IOV with up to 64 virtual functions per 10GbE link
Performance features: TCP/IP Offload Engine (TOE) TCP segmentation/large send offload Receive-side scaling (RSS) for IPv4 and IPv6 TCP/IP checksum offload for IPv4 and IPv6 UDP/IP checksum offload for IPv4 and IPv6 Message signal interrupt (MSI, MSI-X) support PXE 2.x support
Wake on LAN (ML2 and Mezzanine cards only) Preboot eXecution Environment (PXE) support IEEE 1588 Precision Time Protocol (PTP)-Ready Network teaming, failover, and load balancing Smart Load Balancing (SLB) Link Aggregation Control Protocol (LACP) and generic trunking
Management using Broadcom Advanced Control Suite management application Support for Network Controller Sideband Interface (NC-SI) for communication with the server's onboard IMM2 management processor. This support enables the sharing the network interface with the IMM2 and the operating system, thereby eliminating the need for a separate management network (ML2 and Mezzanine cards only) Power consumption: Single port mezz card: 4.74 W typical Dual port mezz card: 7.14 W typical Dual port ML2 card: 14.4 W typical Dual port PCIe card: 7.08 W typical
The Broadcom Single Port 10 GbE SPF+ Embedded Adapter for System x is shown in the following figure. The adapter is ideal for solutions where price sensitivity is paramount and where port-level redundancy is not required.
