Teradata Database addresses the critical requirements of reliability, availability, serviceability, usability, and installability (RASUI) by combining the following elements:
- Multiple microprocessors in a Symmetric Multi-Processing, (SMP) arrangement.
- RAID disk storage technology.
- Protection of Teradata Database from operating anomalies of the client platform.
Both hardware and software provide fault tolerance, some of which is mandatory and some of which is optional.
