Part number information
The following table provides the ordering part numbers and feature codes for the Intel E830-XXV adapters.
The option part numbers includes the following items:
- One Intel Ethernet adapter
- PCIe adapters: Low profile (2U) bracket attached with full-height (3U) bracket included in the box
- Documentation flyer
Note: The adapters ship without any SFP28 transceivers or direct attach cables. These items must be ordered separately as listed in the following section.
Supported transceivers and cables
The Intel E830-XXV 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.
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.
The following table lists the supported optical cables.
The following table lists the supported direct-attach copper (DAC) cables.
Features
The ThinkSystem Intel E830-XXV 10/25GbE Ethernet Adapters offer leading performance, security, manageability, and interoperability without the technical complexity and the high cost of proprietary technologies. The Intel E830-XXV adapters support solutions across Cloud, Enterprise, and Communications with concurrent support of iWARP and RoCEv2 RDMA, modern security features, and key timing protocols. The low power design enables decreased energy consumption across the system to reduce costs and environmental impact, solving increasingly important power density challenges.
Optimized for Intel Xeon processors
Every data center and workload need computing capacity and powerful ways to move data securely. Intel architecture offers both. Deployment-ready, reliable, and affordable, Intel Ethernet E830 Network Adapters are the perfect choice for amplifying performance for servers with Intel Xeon 6 processors.
Remote Direct Memory Access (RDMA)
Both RoCEv2 and iWARP protocols are offered, and for added flexibility, RoCEv2 and iWARP can run concurrently.
Programmable Pipeline / Dynamic Device Personalization (DDP)
DDP improves packet processing performance by using the E830 Controller's programmable pipeline to classify frames instead of the CPU. DDP increases throughput, lowers latency, and reduces host CPU overhead in both network functions virtualization (NFV) workloads and cloud-native architectures.
Data Plane Development Kit (DPDK)
DPDK enabled to deliver faster NFV, advanced packet forwarding, and efficient packet processing resulting in effective use of CPU cycles and reduced overhead.
Precision Time Synchronization and Measurement
Growth in 5G RAN and edge deployments is driving demand for high-precision timing synchronization across the network.
Intel Ethernet E830 Network Adapters enable service providers to build open, disaggregated vRAN solutions with off-the-shelf components to meet unique customer needs, including system size and budget.
- Compliant with IEEE 1588 Precision Time Protocol (PTP) v2.
- Includes Precision Time Measurement (PTM) v1.0a, a protocol used to synchronize a CPU with other devices in a server platform, such as E830 network adapters. Applications benefitting from PTM sub-microsecond timing accuracy include financial services, network monitoring, and distributed database systems.
Manageability
Broad system manageability capabilities using the latest DTMF (Distributed Management Task Force) protocols.
- NC-SI 1.2 protocol compliance. Transport options include NC-SI over RBT, NC-SI over MCTP.
- Secured messages using SPDM over MCTP.
- PLDM over RBT with an extended list of message types, including T4, T5, T6 over RBT and MCTP transport.
Open vSwitch (OVS) Acceleration
The E830 is optimized for Intel Xeon processors to minimize packet parsing overhead and flow table search. DPDK integration with OVS increases performance by eliminating extra layers in the architecture and native OVS stack.
Modern Standards-based Security
Intel offers modern standards-based cryptographic security anchored by a hardware Root of Trust (RoT).
- Unsigned device attestation in compliance with SPDM 1.1.2 Security Protocol and Data Model.
- Silicon Root of Trust (RoT) compliant with NIST SP 800-193 platform firmware resiliency guidelines.
