This example -will use Spirent TestCenter v4.57 as an example. Substitute the appropriate -version in place of 'v4.57' in the examples, below. - -On the CentOS 7 System -~~~~~~~~~~~~~~~~~~~~~~ - -Download and install the following: - -Spirent TestCenter Application, v4.57 for 64-bit Linux Client - -Spirent Virtual Deployment Service (VDS) -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -Spirent VDS is required for both TestCenter hardware and virtual -chassis in the vsperf environment. For installation, select the version -that matches the Spirent TestCenter Application version. For v4.57, -the matching VDS version is 1.0.55. Download either the ova (VMware) -or qcow2 (QEMU) image and create a VM with it. Initialize the VM -according to Spirent installation instructions. - -Using Spirent TestCenter Virtual (STCv) -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -STCv is available in both ova (VMware) and qcow2 (QEMU) formats. For -VMware, download: - -Spirent TestCenter Virtual Machine for VMware, v4.57 for Hypervisor - VMware ESX.ESXi - -Virtual test port performance is affected by the hypervisor configuration. For -best practice results in deploying STCv, the following is suggested: - -- Create a single VM with two test ports rather than two VMs with one port each -- Set STCv in DPDK mode -- Give STCv 2*n + 1 cores, where n = the number of ports. For vsperf, cores = 5. -- Turning off hyperthreading and pinning these cores will improve performance -- Give STCv 2 GB of RAM - -To get the highest performance and accuracy, Spirent TestCenter hardware is -recommended. vsperf can run with either stype test ports. |
