Teradata VantageCore VMware with EDW architecture provides a balance between efficient operational performance and a modest reservation of compute and I/O capability to mitigate potential impacts to performance continuity. The conditions that impact performance continuity include:
- Degraded conditions, such as a failed controller or drive.
- Infrastructure software and firmware updates (such as BIOS, ESXi updates, and so on) that may cause additional overhead for the platform.
- New generations of hardware introduced into the system that have a lower performance level for certain workloads.
