Management Node:

• Management Node:
• The VCSA is deployed with the configuration that synchronized time with ESXi host. The deployment is small
• There is 1 datacenter containing two clusters: one for 1 client host and one for 4 SUT hosts
• SUT cluster is configured with DRS enabled, fully automatic
• vSphere DRS Migration Threshold level set to 2
• DRS Advanced Settings : AggresiveCPU Active = 1

Client Driver Notes:

• All svdc clients and the svdc-director were VMs created using SPECvirt Datacenter 2021 template.
• Each svdc client has 4 vCPUs, 8GB memory, 12GB disk, 1 VMware VMXNET Ethernet Controller (rev 01) and 1 VMware PVSCSI SCSI Controller (rev 02)
• The svdc-director has 8 vCPUs, 24GB memory, 12GB OS disk, 75GB datastore disk, 2 VMware VMXNET Ethernet Controller (rev 01) and 1 PVSCSI SCSI Controller (rev 02)
• The second VMware VMXNET Ethernet Controller(rev 01) on the svdc-director was used as an external management port
