Precision Time Protocol (IEEE 1588 PTP)
Synchronization of system clocks throughout a network, achieving clock accuracy in the sub
-
microsecond range, making it suitable for
measurement and control systems.
RDMA
Remote Direct memory Access (RDMA)
is an accelerated I/O delivery mechanism that
allows data to be transferred directly from the
user memory of the source server to the user memory of the destination server bypassing the operating system (OS) kernel. Because
the RDMA data transfer is performed by the DMA engine on the adapter's network processor, the CPU is not used for the data
movement, freeing it to perform other tasks such as hosting more virtual workloads (increased VM density).
RDMA protocols include
RoCEv1, RoCEv2 and
iWARP. All of these protocols reduce overall latency to
deliver accelerated performance for applications such as
Microsoft Hyper
-V Live Migration, Microsoft SQL and Microsoft SharePoint with SMB Direct..
Receive Flow Steering (RFS)
Receive Flow Steering (RFS) acceleration improves processing efficiency by steering received packets to the CPU core that is running
the application that consumes those packets. Aligning I/O processing to the CPU core running the application improves cache
efficiency, CPU utilization, throughput and latency.
Receive Side Scaling (RSS)
RSS resolves the single
-
processor bottleneck by allowing the receive side network load from a network adapter to be shared across
multiple processors. RSS enables packet receive
-processing to scale with the number of available processors.
Sanitization
Sanitization (Secure User Data Erase) renders User and configuration data on the NIC irretrievable so that NICs can be safely
repurposed or disposed.
Secure Boot
Secure Boot safeguards the system and ensures no rogue drivers are being executed on start-up.
