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
