The following figure shows the ThinkSystem 10Gb 2-port Base-T LOM adapter which provides two RJ45
10GBASE-T ports.
Tip: Ports 1 is at further away from the edge connector and Port 2 is at the bottom, closer to the edge
connector.

Features
The Intel X722 controller is optimized for data center, cloud, and mobile applications and includes the
following features:
VXLAN/NVGRE Hardware Offloads: These stateless offloads preserve application performance for
overlay networks. With these offloads, it is possible to distribute network traffic across CPU cores.
At the same time, the controller offloads LSO, GSO, and checksum from the host software, which
reduces CPU overhead.
Low latency: Intel Ethernet Flow Director delivers hardware-based application steering and Intel
Data Direct I/O makes the processor cache the primary destination and source of I/O data rather
than main memory.
Virtualization performance: With Intel Virtualization Technology (VT), the controller delivers
outstanding I/O performance in virtualized server environments. The controller reduces I/O
bottlenecks by providing intelligent offloads for networking traffic per virtual machine (VM), which
enables near-line rate speeds for small packets and supports almost an unlimited amount of
isolated traffic flows so that you can scale your cloud environment.
Next-generation VMDq: The controller support up to 128 VMDq VMs and offer enhanced Quality of
Service (QoS) feature by providing weighted round-robin servicing for the Tx data. The controller
offloads the data-sorting functionality from the hypervisor to the network silicon, which improves
data throughput and CPU usage.
SR-IOV implementation: Provides an implementation of the PCI-SIG standard for I/O Virtualization.
The physical configuration of each port is divided into multiple virtual ports. Each virtual port is
assigned to an individual VM directly by bypassing the virtual switch in the Hypervisor, which results
in near-native performance.
iWarp RDMA support implements kernel bypass and direct data placement and allows for more
efficient high-speed networking by eliminating queues and network related interrupts
