3. Hardware Notes

This section shows a list of the different hardware used during the official testing of RTI Connext DDS Professional and RTI Connext DDS Secure.

The relevant hardware is also shown under the individual test graphs, via the “Test Hardware” sections. Below is a summary of all hardware used, across all tests.

3.1. One-to-One Numbers

3.1.1. x64 Linux Lab

Switch

Dell Networking S4048T-ON, 48x 10GBASE-T and 6x 40GbE QSFP+ ports, IO to PSU air, 2x AC PSU, OS9

3.1.3. ARM v8 Raspberry Pi Lab

Raspberry Pi 4 Model B

Processor: Broadcom BCM2711, Quad core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz
RAM: 4GB LPDDR4-3200 SDRAM
NIC 1: Gigabit Ethernet
OS: Raspbian (x32)

.. Note::
    These machines are using the most popular OS in a Raspberry, which is
    **Raspbian** (Devian for Raspberry). This however is not the ideal choice
    in terms of performance, as it is a 32 bits OS in a 64 bits CPU.
