Linux on z Systems: simple, efficient, secure – an enterprise grade Linux
Linux on z Systems can do more with less, providing IT organizations a robust and effective enterprise grade Linux platform for new workload deployment and consolidation to eliminate complexity. Linux on z benefits from the synergistic combination of Linux, the unmatched power of IBM z Systems, z/VM virtualization and IBM Wave for z/VM virtualization management technologies.
While Linux on z is based on the common Linux kernel, has the same look and feel as every Linux, it can provide advantages not available with other platforms.
Linux on z can help to build an IT infrastructure that:
- Provides efficiency at scale on a single physical server
- Delivers industry-leading virtualization for effective deployment
- Enables flexible delivery of services
- Allows for fast data access and high utilization efficiency
- Provides robust security, built-in from bottom to top
- Delivers resilience and availability with high qualities of service
The cost benefits
Linux on z Systems can help lower your IT costs by running up to hundreds of virtual Linux servers concurrently with ensured isolation of each virtual server. Workload deployment onto a single z Systems server, including consolidation of distributed servers, provide cost reduction opportunities in:
- Operational management and maintenance costs
The single server solution allows mastering the IT infrastructure with a cost advantage in regard to operational management and maintenance. Fewer servers mean less server maintenance, less cables and switches, less efforts. 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 help reduce the errors and minimize workload-balancing tasks that otherwise can consume IT staff hours.

- 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 Linux on z you get more benefit from your software license.

- 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.

- Security and business continuity costs
z Systems are the most secure commercial servers available, built using groundbreaking technology you can trust. Powerful encryption will ensure your data and therefore your business, is protected 24/7. Linux on z allows running workloads with the highest security requirements, supporting acceleration of and access to complex cryptographic algorithms available with the cryptographic hardware.
The suite of the z Systems built-in features, e.g. IBM zAware, can rapidly respond to, or even anticipate, threats to system health, helping to prevent costly system downtime. As well, high availability and disaster recovery solutions are available, and IBM intends* to improve it further with the GDPS/PPRC capabilities for Linux clients not running z/OS.
