IBM revamps zOS

Enhancements to scalability, management and security are in the pipeline with IBM's new high-end operating system.

IBM has announced the availability of z/OS, a self-managing 64-bit operating system for the IBM eServer z900.

z/OS features Intelligent Resource Director (IRD), an IBM technology that makes the z900 capable of automatically reallocating processing power to a given application on the fly, based on the workload demands being experienced by the system at that moment. This technology allows the z900 and z/OS to provide capacity and scalability according to priorities determined by the manager.

“We are giving our customers…agility - the ability to configure, connect, extend, operate, and optimise their central computing resources,” said Rich Lechner, vice president, IBM Enterprise Servers

Other benefits of z/OS include support for 64-bit storage and advances to simplify system set up. Where previously special mainframe skills were needed to configure the system, the new method uses Web-based wizard technology. Workstation-based dialogues guide customers step-by-step through the tasks required for installation and configuration.

Further enhancements are due to become available later this year with the introduction of z/OS 1.2. These include Intelligent Resource Director for Linux and networking advances that will use server memory to allow information to travel at memory speed across logical partitions, minimizing network latency, maximizing bandwidth and improving availability.

For security, z/OS 1.2 will introduce new intrusion detection functions as well as enhancements to distributed security, digital certificates, directory services, and cryptography.
