IBM System z, or earlier IBM eServer zSeries
IBM System z, or earlier IBM eServer zSeries, is a brand name designated by IBM to all of its recent mainframe computers.
In 2000, IBM rebranded the existing System/390 to IBM eServer zSeries with the 'e' depicted in IBM's red trademarked symbol. Since April 2006, with another generation of products, the official designation has changed to IBM System z, which now includes both older IBM eServer zSeries, the IBM System z9 models, and the newer IBM System z10 models.
Both zSeries and System z brands are named for their availability - z stands for zero downtime. The systems are built with redundant components capable of hot failovers and concurrent replacement features to ensure continuous operations.
