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. Two testbed topologies are
12 - **3-Node Topology**: Consisting of two servers acting as SUTs
13 (Systems Under Test) and one server as TG (Traffic Generator), all
14 connected in ring topology. Used for executing all of the data plane
15 tests including overlay tunnels and IPSec tests.
16 - **2-Node Topology**: Consisting of one server acting as SUTs (Systems
17 Under Test) and one server as TG (Traffic Generator), both connected
18 in ring topology. Used for execution of tests without any overlay
19 tunnel encapsulations. Added in CSIT rls18.07.
21 Current FD.io production testbeds are built with servers based on two
22 processor generations of Intel Xeons: Haswell-SP (E5-2699v3) and Skylake
23 (Platinum 8180). Testbeds built with servers based on Arm processors are
24 in the process of being added to FD.io production.
26 Server SUT and DUT performance depends on server and processor type,
27 hence results for testbeds based on different servers must be reported
28 separately, and compared if appropriate.
30 Complete technical specifications of compute servers used in CSIT
31 physical testbeds are maintained in FD.io CSIT repository:
32 `FD.io CSIT testbeds - Xeon Skylake, Arm, Atom`_ and
33 `FD.io CSIT Testbeds - Xeon Haswell`_.
35 Following sections describe existing production testbed types.
