1 .. _tested_physical_topologies:
6 All :abbr:`FD.io (Fast Data Input/Ouput)` :abbr:`CSIT (Continuous System
7 Integration and Testing)` performance testing listed in this report are
8 executed on physical testbeds built with bare-metal servers hosted by
9 :abbr:`LF (Linux Foundation)` FD.io project.
11 Two testbed topologies are used:
13 - **3-Node Topology**: Consisting of two servers acting as SUTs
14 (Systems Under Test) and one server as TG (Traffic Generator), all
15 connected in ring topology. Used for executing all of the data plane
16 tests including overlay tunnels and IPSec tests.
17 - **2-Node Topology**: Consisting of one server acting as SUTs (Systems
18 Under Test) and one server as TG (Traffic Generator), both connected
19 in ring topology. Used for execution of tests without any overlay
20 tunnel encapsulations. Added in CSIT rls18.07.
22 Current FD.io production testbeds are built with servers based on two
23 processor generations of Intel Xeons: Haswell-SP (E5-2699v3) and Skylake
24 (Platinum 8180). Testbeds built with servers based on Arm processors are
25 in the process of being added to FD.io production.
27 Server SUT and DUT performance depends on server and processor type,
28 hence results for testbeds based on different servers must be reported
29 separately, and compared if appropriate.
31 Following sections describe existing production testbed types.
33 3-Node Xeon Haswell (3n-hsw)
