Linux on IBM z Systems

Linux on z Systems – an enterprise grade Linux solution

While the Linux operating system on the IBM mainframe is based on the common Linux kernel, it has the same look and feel as every Linux, Linux on z can offers savings plus reliability, security, and scalability not available with other platforms.

Running the Linux os on z Systems provides an enterprise grade Linux solution, especially with the new IBM z13 (z13), and from the synergistic combination with the impressive z/VM virtualization and IBM Wave for z/VM virtualization management, and other technologies such as IBM Spectrum Scale—based on IBM GPFS, IBM zAware and the IBM GDPS Virtual Appliance. Each adding values and providing the overall enterprise grade Linux solution.

What can Linux on the IBM mainframe do for your infrastructure?

Linux on z Systems cost benefits

Lower operational and maintenance costs

The single Linux server solution mean less server maintenance, less cables and switches, less efforts and therefore allows mastering the IT infrastructure with lower operational management and maintenance costs. Physical and virtual resources can be dynamically shared or reconfigured, helping to simplify the demands placed upon your IT staff. The centralized management available with IBM Wave and the additional autonomic computing capabilities of the Linux on z environment can reduce errors and minimize workload-balancing.

Lower software acquisition and licenses costs

A single z Systems processor can run a mass of Linux applications and running software on fewer processors can result in fewer licenses and support costs, due to the fact that Linux software is usually priced on a per-core basis. Since the software costs are the same for a low-utilized processor or a well-utilized processor, the high resource utilization of z Systems also contributes to the software savings. With the Linux operating system on z you get more benefit from your software license.

Lower floor space and energy costs

Fewer servers and networks can require less floor space and can mean savings not only in acquisition costs, but even more important in heating, air conditioning and electricity costs. The modular design, efficient dense packaging, high efficiency power supplies, resource sharing and industry-leading virtualization - all this contributes to the energy and space efficiency of z Systems. Companies can reduce their carbon footprint by leveraging the energy-efficient, single Linux server solution.

  • EVERTEC has significantly cut down on administrative costs and energy requirements

Lower security and business continuity costs

z Systems are the most secure commercial servers available. Powerful encryption ensures data is protected 24/7. Linux on the IBM mainframe can run workloads with the highest security requirements, supporting complex cryptographic algorithms with cryptographic hardware. z Systems built-in features, e.g. IBM zAware, can respond to, and even anticipate, threats to system health to prevent costly downtime. High availability and disaster recovery is available, for example with the IBM GDPS solutions.
