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

Notification) IPv4 (RFQ 791) IPv6 (RFC 2460)
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.
