The following table lists guidelines for sample vNode configurations.

vNode Configuration vCPU (Minimum) Memory (Minimum) Storage (Minimum) Separate Physical Network
Production Systems
Single vNode Min 6 vCores 3 GB per AMP 3+ .vmdk files Recommend using separate physical networks for high performance.
Two vNodes Min 6 vCores 3 GB per AMP 6+ .vmdk files
  • 1 Customer/Public
  • 1 BYNET with 2 Ethernet networks for redundancy
  • 1 Server Management (CMIC) VM
  • 1 DSC
Development/Test Systems
Single vNode Min 2 vCores 3 GB per AMP 3+ .vmdk files
  • SMP: 1 Customer/Public, 2 CMIC, and 1 DSC
  • MPP: 1 Customer/Public, 2 BYNET, 2 CMIC, and 1 DSC
Two vNodes Min 2 vCores 3 GB per AMP 6+ .vmdk files
  • 1 Customer/Public
  • 2 BYNET switches (vLANs)
  • 1 Server Management (CMIC) VM
  • 1 DSC

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. 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.

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.
