Embedded NICs/LAN on Motherboard (LOM)
10.1
Overview
The
Dell™ PowerEdge™ M610 planar has
two embedded Broadcom
®
5709S dual-port LAN controllers as
independent Gigabit Ethernet interface devices. The following information details the features of the
LAN devices:
•
x4 PCI Express Gen2 capable interface (M610 operates this controller at Gen1 speed )
•
Integrated MAC and PHY
•
3072x18 Byte context memory
•
64 KB receive buffer
•
TOE (TCP Offload Engine)
•
RDMA controller (RNIC)
•
NC-SI (Network Controller-Sideband Interface) connection for manageability
•
Wake-On-LAN (WOL)
•
PXE 2.0 remote boot
•
iSCSI boot
•
IPv4 and IPv6 support
•
Bare metal deployment support
•
ISCSI offload accelerator used for offloading ISCSI traffic as an ISCSI accelerator/HBA
(optionally enabled through a hardware key)
The embedded NICs are not sharable with iDRAC since the blade iDRAC has a dedicated 100 Mbps link
(Fabric D).
10.2
Platform Networking LAN on Motherboard (LOM) Technology
Overview
The PowerEdge M610 has two Ethernet ports because it includes two built-in dual-port 1GbE
converged networking (CNIC) LOMs based on Broadcom 5709 controllers. The M610 supports multiple
functions over a unified fabric to help manage Ethernet, iSCSI, and remote management traffic on
each port simultaneously.
Enterprise networks that use multiple protocols and multiple network fabrics benefit from the
Broadcom C-NICs LOMs’ ability to combine network traffic, storage, and clustering over a single
Ethernet fabric by boosting server processor performance and memory utilization while alleviating
I/O bottlenecks.
Each BCM5709S LOM provides dual 10/100/1000BASE-T Gigabit Ethernet functions, an IEEE802.3-
compliant media access controller (MAC), and a UTP copper physical layer transceiver solution for
high-performance network applications. It enables simultaneous convergence of all networked
communications possible in a server, such as data network (LAN), storage network (such as block,
iSCSI, or file [for example, CIFS/NFS]), and clustering (such as High-Performance Computing [HPC]).
