HPE 840QSFP28 - Network adapter - PCIe 3.0 x16 low profile - 100Gb Ethernet / Infiniband EDR QSFP28 x 2 - for Apollo 35 v2
- Improved thermal control with HPE ProLiant XL and DL servers
- PXE boot over InfiniBand or Ethernet
- Port personality configuration via UEFI
HPE EDR InfiniBand/Ethernet 100G 2-port 840QSFP28 adapter is based on Mellanox ConnectX-4 technology. It supports dual-function InfiniBand and Ethernet for HPE ProLiant XL and DL Servers. It can function as a dual ported EDR InfiniBand card, a dual ported 100Gb Ethernet card, or a mixed function card. They are designed for customers who need low latency and high bandwidth interconnector in their high performance computing (HPC) systems.
-
Management support
The HPE 840QSFP28 adapter can be administered from HPE Systems Insight Manager (SIM).
-
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.
-
Single-Root I/O Virtualization
Single-Root I/O Virtualization (SR-IOV) provides a mechanism to bypass the host system hypervisor in virtual environments providing near metal performance and server efficiency. SR-IOV provides mechanism to create multiple Virtual Functions (VFs) to share single PCIe resources. The device is capable of SR-IOV, and requires Server BIOS support, controller firmware, and OS support.

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.
