The Intel Ethernet Connection X722 shares the same core and drivers
as the Intel X710 adapters making driver management easier of
existing customers.
ThinkSystem LOM adapters are cost-effective adapters that take
advantage of the X722 controller embedded in Intel Xeon Processor
Scalable Family chipset and offer the flexibility advantages of a
PCIe adapter while supporting integrated networking features, such
as Wake-on-LAN and direct connectivity to the XClarity Controller
management processor for NC-SI-compliant systems management.
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
•VM load balancing: Provides traffic load balancing (Tx and Rx)
across VMs that are bound to the team interface. It also provides
fault tolerance if a switch, port, or cable.
•Auto-detect (PnP) feature for the LOM adapters, enabling you to
change LOM adapters (eg from a 1Gb LOM to 10 Gb LOM) and the
network interface will automatically reconfigure during the boot
process
