IBM z Mainframes

The most advanced systems for clients requiring the highest computing power.

  • IBM z800, z9, z10, z114, z196, z12, z13

IBM eServer and zSeries corporate servers, or successors of the IBM S / 390 Parallel Enterprise Server, is the family of the most efficient and advanced computing Z-systems. IBM is currently the only Mainframe server manufacturer, developing this technology for over 36 years. These devices are designed to process large amounts of data of key importance for the company's operations. Reliability of Mainframe systems reaches the level of 99.999% (downtime up to 5 minutes in a year). IBM eServer, zSeries is a multi-application server, balancing the use of processor resources, memory and bandwidth of input / output channels. In contrast to PC and UNIX servers, Mainframe provides the ability to connect servers, translating into even greater reliability and application performance. Currently, approximately 70% of corporate data is processed on mainframe servers.
