Historical building block VMs are still supported:

vCPUs/VM Min Memory/VM AMPs/VM Pdisks/VM
6 vCPU or less 18 6 3
12 vCPU 36 12 3

VantageCore VMware 4.0 supports larger VMs, allowing for better utilization of the ESXi host and storage resources. Two VMs per ESXi host is the recommended configuration for larger multi-ESXi production systems.

Teradata Parallel architecture requires that all ESXi hosts have the same hardware as the speed of the system will run at the speed of the slowest VM. VantageCore VMware supports ESXi hosts with dual socket configurations, which includes NUMA architecture considerations. VantageCore VMware will deploy two VMs on a single ESXi host and ensures that the VMs do not cross NUMA boundaries by limiting the physical cores assignable to a VM to that of a single socket. Two physical cores from each socket will be reserved for ESXi.

Increasing the physical cores of a VM does not guarantee a uniform performance increase. A bottleneck can easily occur in other areas of resource contention such as storage i/o, network, and memory.

VantageCore VMware does not provide Service Level Agreements relative to performance for customer-provided hardware and configuration thereof.

Size vCPUs/VM Min Memory/VM AMPs/VM Pdisks/VM
Small 16 to 28 72GB 18 9
Medium 32 to 52 96GB 24 12
Large 60 to 108 144GB 36 18

For Higher Availability (HA), multi-node cliques can be deployed that leverage external storage arrays that support iSCSI. This is a Reference Architecture that has very specific hardware requirements. Contact the VantageCore VMware Product Management team for details.
