3 Performance Physical Testbeds
4 =============================
6 All :abbr:`FD.io (Fast Data Input/Ouput)` :abbr:`CSIT (Continuous System
7 Integration and Testing)` performance test results included in this
8 report are executed on the physical testbeds hosted by :abbr:`LF (Linux
9 Foundation)` FD.io project, unless otherwise noted.
11 Two physical server topology types are used:
13 - **2-Node Topology**: Consists of one server acting as a System Under
14 Test (SUT) and one server acting as a Traffic Generator (TG), with
15 both servers connected into a ring topology. Used for executing tests
16 that require frame encapsulations supported by TG.
18 - **3-Node Topology**: Consists of two servers acting as a Systems Under
19 Test (SUTs) and one server acting as a Traffic Generator (TG), with
20 all servers connected into a ring topology. Used for executing tests
21 that require frame encapsulations not supported by TG e.g. certain
22 overlay tunnel encapsulations and IPsec. Number of native Ethernet,
23 IPv4 and IPv6 encapsulation tests are also executed on these testbeds,
24 for comparison with 2-Node Topology.
26 Current FD.io production testbeds are built with SUT servers based on
27 the following processor architectures:
29 - Intel Xeon: Skylake Platinum 8180, Cascadelake 6252N, (Icelake 8358
31 - Intel Atom: Denverton C3858.
32 - Arm: TaiShan 2280, hip07-d05.
33 - AMD EPYC: Zen2 7532.
35 CSIT-2106 report data for Intel Xeon Icelake testbeds comes from
36 testbeds in Intel labs set up per CSIT specification and running CSIT
37 code. Physical setup used is specified in 2n-icx and 3n-icx sections
38 below. For details about tested VPP and CSIT versions
39 see :ref:`vpp_performance_tests_release_notes`.
41 Server SUT performance depends on server and processor type, hence
42 results for testbeds based on different servers must be reported
43 separately, and compared if appropriate.
45 Complete technical specifications of compute servers used in CSIT
46 physical testbeds are maintained in FD.io CSIT repository:
47 https://git.fd.io/csit/tree/docs/lab/testbed_specifications.md.
49 Physical NICs and Drivers
50 -------------------------
52 SUT and TG servers are equipped with a number of different NIC models.
54 VPP is performance tested on SUTs with the following NICs and drivers:
56 #. 2p10GE: x520, x550, x553 Intel (codename Niantic)
57 - DPDK Poll Mode Driver (PMD).
58 #. 4p10GE: x710-DA4 Intel (codename Fortville, FVL)
62 #. 2p25GE: xxv710-DA2 Intel (codename Fortville, FVL)
66 #. 2p100GE: cx556a-edat Mellanox ConnectX5
67 - RDMA_core in PMD mode.
68 #. 2p100GE: E810-2CQDA2 Intel (codename Columbiaville, CVL)
72 DPDK applications, testpmd and l3fwd, are performance tested on the same
73 SUTs exclusively with DPDK drivers for all NICs.
75 TRex running on TGs is using DPDK drivers for all NICs.
77 VPP hoststack tests utilize ab (Apache HTTP server benchmarking tool)
78 running on TGs and using Linux drivers for all NICs.
