Supported transceivers and cables
The Intel E810 adapters have empty SFP28 cages for connectivity. The adapter either supports connections to a 10 Gb or 25 Gb switch or can share a connection to a 100 Gb switch using a 4:1 breakout cable.
The following table lists the supported transceivers.
Table 2. Transceivers

Part number	Feature code	Description

25Gb transceivers: When installed in this 25Gb Ethernet adapter, 25Gb transceivers are designed to operate at either 25 Gb/s or 10 Gb/s speeds as listed in the description of the transceiver, however the speed also depends on the negotiation with the connected switch. In most configurations, this negotiation is automatic, however in some configurations you may have to manually set the link speed or FEC mode.

Features

Performance optimizations for Cloud, Enterprise, and Storage deployments

Application Device Queues (ADQ) provides dedicated traffic queues to reduce latency and increase application throughput
Dynamic Device Personalization enables protocol- specific traffic acceleration to improve packet processing efficiency and reduce CPU overhead
iWARP and RoCEv2 support provides high-speed, low-latency, high-throughput connectivity for storage targets and initiators

Accelerated packet processing for Communications workloads

Enhanced Data Plane Development Kit (DPDK) support increases packet processing speeds
Dynamic Device Personalization enables protocol- specific traffic acceleration and reduces CPU overhead for emerging high-bandwidth workloads
IEEE 1588 PTP v2 support enables precise clock synchronization across 5G RAN deployments

Application Device Queues (ADQ) for Predictability at Scale
As modern data centers scale, a key challenge is to provide scalable, predictable application-level performance. ADQ technology improves performance scalability and predictability by dedicating queues to key workloads, delivering predictable high performance through dramatically reduced jitter.
Increasing the predictability of application response times by lowering jitter enables more servers to be assigned to a task and can allow more users to access the system, providing a better end-user experience.
Even applications that are not large scale can benefit from higher consistency, enabling them to meet service-level agreements (SLAs) more easily.
ADQ enables application-specific data steering, signaling, and rate limiting using an optimized application thread to device data path. This ability to dedicate queues and shape network traffic not only increases performance, it reduces latency and improves throughput.

Improve Packet Processing Efficiency with Dynamic Device Personalization (DDP)
DDP customizable packet filtering, along with enhanced DPDK, support advanced packet forwarding and highly-efficient packet processing for both Cloud and NFV workloads.
The Intel E810 adapter firmware loads an enhanced DDP profile with many workload-specific protocols at driver initialization for greater flexibility. When multiple Intel E810 adapters are present in a system, the pipeline on each adapter can be programmed independently with a different DDP profile.

IEEE 1588 Precision Time Protocol (PTP)
Intel E810 adapters support both IEEE 1588 PTP v1 and v2 with two-step option. The products provide increased accuracy at single-digit nanosecond level, and can report the reception time for every packet.
This level of timing accuracy can help ensure tight synchronization across network deployments ranging from 5G RAN to financial services, industrial automation, and energy monitoring.

Increase Throughput and Lower Latency with Remote Direct Memory Access (RDMA)
RDMA provides high throughput and low-latency performance for modern high- speed Ethernet by eliminating three major sources of networking overhead: TCP/IP stack process, memory copies, and application context switches. Intel E810 adapters support all major storage transport protocols, including iWARP, RoCEv2, and NVMe over TCP.
RoCE (RDMA over Converged Ethernet): RoCEv2 substitutes the InfiniBand physical layer and data link layer with Ethernet, operates on top of UDP/IP, and is routable over IP networks.
iWARP, IETF standard protocols based: Delivers RDMA on top of the pervasive TCP/IP protocol. iWARP RDMA runs over standard network and transport layers and works with all Ethernet network infrastructure.
TCP provides flow control and congestion management and does not require a lossless Ethernet network.
iWARP is a highly routable and scalable RDMA implementation.

Protect, Detect, and Recover
Zero Trust is a security design strategy centered on the belief that organizations, by default, should not automatically trust any request for system access. This includes requests coming from outside, as well as inside its perimeters. Zero Trust demands that every access request be verified before granting access.
The Intel E810 adapters implement a design philosophy of platform resiliency with 3 attributes compliant with the NIST Cybersecurity Framework, including NIST 800-193 Platform Firmware Resiliency Guidelines:
Protect, Detect and Recover. By design, the Hardware Root of Trust in the adapters protect the firmware and critical device settings with authentication for every access. Signed firmware updates and the Hardware Root of Trust protects and verifies critical device settings with built-in corruption detection and automated device recovery. Together these features ensure the device safely returns to its originally programmed state.
