The SBC Core release 8.2 includes a feature that extends the use of hyper-threading to SBC SWe when it is installed on either the VMware or KVM Hypervisor platform. To take advantage of the performance improvements provided by hyper-threading, you must increase (double) the number of vCPUs configured in the VM prior to software upgrade. When upgrading, modify the upgrade process to incorporate the following additional steps:
...
- On the VMware platform only, before beginning the upgrade, disable the CPU reservation check inside the guest by renaming the file: vmware-toolbox-cmd. For example, issue the following command:
mv /usr/bin/vmware-toolbox-cmd /usr/bin/vmware-toolbox-cmd.bak - Stop standby SBC by issuing "sbxstop". Wait until the SBC processes stop.
- Shutdown the standby SBC by issuing "power off" command.
- Increase vCPU count on the powered off standby SBC.
- Stop active SBC by issuing "sbxstop". Wait until the SBC processes stop. Note that this is service affecting since both SBCs are stopped now.
- Shutdown the active SBC by issuing "power off" command.
- Increase vCPU count on the powered off active SBC.
- Power on an active SBC. Wait for the SBC to fully start as active.
- Power on a standby SBC. The SBCs should start as standby and get in sync with active SBC.
