- VPP Performance Test
- Performance data on Arm in official release 19.08 is available.
- Performance job is merged. https://jenkins.fd.io/view/csit/job/csit-vpp-perf-mrr-daily-master-3n-tsh
- Trending data recorded with https://docs.fd.io/csit/master/trending/introduction/introduction.html
- Trending page: https://docs.fd.io/csit/master/trending/index.html
- There's a Python API issue which affects all performance tests on Taishan server only.
- VPP Path
- Looks like it would be only build and unit test. VPP device and performance tests would run on the physical devices in the lab.
- cross compilation in VPP PATH. Jira(Juraj): https://jira.fd.io/browse/CTP-3
- Tried cross-compiling with DPDK only.
- Initial cross-compiling is working fine.
- Patch is under review. https://gerrit.fd.io/r/#/c/vpp/+/21035/
- There's issues to build vpp distros.
- what is not finished is packaging - currently we support Ubuntu's DEB packages for aarch64 architecture (make PLATFORM=aarch64-generic pkg-deb) this is what I currently am trying to sort out ...
- We can put the cross-compiling knowledge into section 'for developers', vpp-docs project.
- Doesn't work, seems to be caused improper cross-building-tools. https://wiki.fd.io/view/VPP/Build_System_Deep_Dive
- https://gerrit.fd.io/r/#/c/vpp/+/21035/, VPP path cross compilation
- setup proper platform specific folder names in DEB packages
- proper architecture string included in the DEB package name
- Loop Nitin, Sachin, Honnappa, Lijian in container cross-compilation discussion.
- VPP Device
- Totally 29 VPP device test cases executed, and all passed on Arm servers.
- Currently VPP device is not executed per patch. Issue is still under investigation.
- VPP device job is running now and will be triggered per VPP patch and CSIT patch

- VPP Performance Test
- FD.io lab
- Confirm the power cable requirements for the Vexxhost lab Inform about the 2 servers coming to the lab - Juraj
- Current Configurations:
- RAM: 256G
- Disk: 480G SSD
- The boxes are coming with Qlogic cards which are not supported in VPP.
- Changes required to the servers:
- The power cable specifications will be 4 x 6ft 14 AWG C13 to C14 Power Cables.
- Need 2 Intel NICs XL710-QDA2 for each server.
- If there is space for 2 more cards, we should add 2 Mellanox cards SR-IOV capability.
- Disk size to 480G
- Both the servers should have the NICs in the same PCIe slots. It does not matter which PCIe slots the cards are in.
- Cables: N1, P1 to N2, P1 and so on
- Cables for IPMI and Management port: 2
- Will call a meeting once the ThunderX2 arrives to Dean, inviting Juraj/Vxxhost people in FD.io lab to make sure hardware ready.
- Require and install 1G NIC for the management port because of the 1G management switch. - Lijian
- Require two ThunderX2(currently only one thunderX2 in the lab) in FD.io lab
- Require one more ThunderX2 to form a normal cluster (1xThunderX + 2xThunderX2), to enable voting right for Arm servers in CSIT
- OS: Ubuntu 18.04

- VPP Performance Test
- FD.io lab
- Confirm the power cable requirements for the Vexxhost lab Inform about the 2 servers coming to the lab - Juraj
- Current Configurations:
- RAM: 256G
- Disk: 480G SSD
- The boxes are coming with Qlogic cards which are not supported in VPP.
- Changes required to the servers:
- The power cable specifications will be 4 x 6ft 14 AWG C13 to C14 Power Cables.
- Need 2 Intel NICs XL710-QDA2 for each server.
- If there is space for 2 more cards, we should add 2 Mellanox cards SR-IOV capability.
- Disk size to 480G
- Both the servers should have the NICs in the same PCIe slots. It does not matter which PCIe slots the cards are in.
- Cables: N1, P1 to N2, P1 and so on
- Cables for IPMI and Management port: 2
- Will call a meeting once the ThunderX2 arrives to Dean, inviting Juraj/Vxxhost people in FD.io lab to make sure hardware ready.
- Require and install 1G NIC for the management port because of the 1G management switch. - Lijian
- Require two ThunderX2(currently only one thunderX2 in the lab) in FD.io lab

- VPP Path
- Looks like it would be only build and unit test. VPP device and performance tests would run on the physical devices in the lab.
- cross compilation in VPP PATH. Jira(Juraj): https://jira.fd.io/browse/CTP-3
- Tried cross-compiling with DPDK only.
- Initial cross-compiling is working fine.
- Patch is under review. https://gerrit.fd.io/r/#/c/vpp/+/21035/
- There's issues to build vpp distros.
- what is not finished is packaging - currently we support Ubuntu's DEB packages for aarch64 architecture (make PLATFORM=aarch64-generic pkg-deb) this is what I currently am trying to sort out ...
- We can put the cross-compiling knowledge into section 'for developers', vpp-docs project.
- Doesn't work, seems to be caused improper cross-building-tools. https://wiki.fd.io/view/VPP/Build_System_Deep_Dive
- https://gerrit.fd.io/r/#/c/vpp/+/21035/, VPP path cross compilation
- setup proper platform specific folder names in DEB packages
- proper architecture string included in the DEB package name
- VPP Device
- https://gerrit.fd.io/r/#/c/vpp/+/21152/ - to fix occasional VPP device failure
- Totally 29 VPP device test cases executed, and all passed on Arm servers.
- Currently VPP device is not executed per patch. Issue is still under investigation.
- VPP device job is running now and will be triggered per VPP patch and CSIT patch

- FD.io lab
- Confirm the power cable requirements for the Vexxhost lab Inform about the 2 servers coming to the lab - Juraj
- Current Configurations:
- RAM: 256G
- Disk: 240G SSD
- The boxes are coming with Qlogic cards which are not supported in VPP.
- Changes required to the servers:
- Need 2 Intel NICs XL710-QDA2 for each server.
- If there is space for 2 more cards, we should add 2 Mellanox cards SR-IOV capability.
- Disk size to 480G
- Both the servers should have the NICs in the same PCIe slots. It does not matter which PCIe slots the cards are in.
- Cables: N1, P1 to N2, P1 and so on
- Cables for IPMI and Management port: 2
- Will call a meeting once the ThunderX2 arrives to Dean, inviting Juraj/Vxxhost people in FD.io lab to make sure hardware ready.
- Require and install 1G NIC for the management port because of the 1G management switch. - Lijian
- Require two ThunderX2(currently only one thunderX2 in the lab) in FD.io lab
- Require one more ThunderX2 to form a normal cluster (1xThunderX + 2xThunderX2), to enable voting right for Arm servers in CSIT

- Daily job is running twice a day on x86; on Arm, it takes 16 hours and will run one time each day.
- Trying to fix all the failures with daily test in performance test. Basically almost all the tests passed locally.
- Some common failures due to Python bindings or something inside VPP image.
- VPP Path
- cross compilation in VPP PATH. Jira(Juraj): https://jira.fd.io/browse/CTP-3

- Initial cross-compiling is working fine.
- Patch is under review. https://gerrit.fd.io/r/#/c/vpp/+/21035/
- There's issues to build vpp distros.
- what is not finished is packaging - currently we support Ubuntu's DEB packages for aarch64 architecture (make PLATFORM=aarch64-generic pkg-deb) this is what I currently am trying to sort out ...
- We can put the cross-compiling knowledge into section 'for developers', vpp-docs project.

- It’s 1RU blade ThunderX2.
- The machine will be handled by Dean’s team. Cambridge folk will set up the machine before sending it to FD.io lab.
- The machine should have a big RAM, more than 120G and 256G preferred.
- The machine should Three NICs (XL710-QDA2, 2x40G).

- Performance job is merged. https://jenkins.fd.io/view/csit/job/csit-vpp-perf-mrr-daily-master-3n-tsh
- Trying to fix all the failures with daily test in performance test. Basically almost all the tests passed locally.
- Only 1 out of 199 test cases failed, 8 test cases show random 'show hardware-interfaces' failure.
- Some failures are related with 'show hardware-interfaces'/'show vhost dump', time-out.
- Juraj to send Lijian the commands/APIs in random dump failure.
- https://jira.fd.io/browse/CSIT-1453
- Will check details with x86 server also. It's slow also on x86, but only 5 sec, but it takes 40 sec on Taishan - Lijian
- It’s quite time-consuming for ‘show hardware-interfaces’ reading eeprom of the SFP, via software emulated I2C bus.
- Adding Taishan test bed to CSIT Status: https://gerrit.fd.io/r/#/c/16850/
