IBM has started shipping the latest version of its mainframe computer to address new markets.
System z9 is the ninth generation of IBM's z-series mainframe platform, which IBM says has twice the capabilities of its predecessor.
The company is aiming System z9 at the world’s largest companies and the government sector, and comes with enhanced security to protect sensitive data.
"There is a groundswell of interest from businesses and governments around what the new class of mainframes can do," said Erich Clementi, general manager of IBM System z9.
"Companies are looking to the mainframe more than ever to help manage some of the most complex corporate issues, such as protecting the security of customer information and complying with regulations. Our deep commitment to Java, Linux, virtualisation and service-oriented architectures on the mainframe are driving adoption," he said.
The platform can handle up to a billion transactions a day and can contain up to 54 processors and 18 billion transistors.
The starting price of the z9 is around $1m (£600,000).
