Dr. John Busch (founder, Chairman, and CTO of Schooner):
Tightly-coupled database architectures utilizing parallel synchronous replication exploiting commodity multi-core servers can achieve 99.999% availability with full data integrity; unlimited scaling with exceptional performance and high data consistency; and greatly simplified administration including instantaneous, automatic fail-over and on-line scaling and upgrades.
Tightly-coupled architectures and high availability used in the same phrase.
