The Solution: Linux on z Systems

- We already had a mainframe

-We had knowledge of z/VM and Linux

- It was simple to install and provide the first Linux on z Systems

- The pilot system fulfilled all requirements for development

Zentrale Systeme | Oliver Röthinger 11/02/2015 1 von X

Why Linux on z Systems ?

The mainframe is optimized for dealing with heavy I/O rates.

Independant I/O processors in system z guarantee highest I/O throuput.

Zentrale Systeme | Oliver Röthinger 11/02/2015 1 von X

Why Linux on z Systems ?

Customer data and transactions need the highest level of security.

IBM z Systems is the only commercial system that reaches EAL 5 (Evaluation Assurance Level 5 Security Classification) if it´s using RACF.

Zentrale Systeme | Oliver Röthinger 11/02/2015 1 von X

Why Linux on z Systems ?

Virtualising Linux with z/VM hypervisor saves time.

Provisioning of new linux images is done in a very short time by cloningGOLDEN Images .

If running in an z/VM SSI Cluster, disaster recovery is simple to implement .

Zentrale Systeme | Oliver Röthinger 11/02/2015 1 von X

Why Linux on z Systems ?

We save money with running Linux on z Systems.

License costs are reduced by consolidating databases on z Systems.

Zentrale Systeme | Oliver Röthinger 11/02/2015 1 von X

Back to 2004

Decision for Linux on z, but which distribution to use?

Our favourite was SUSE Linux Enterprise Server because:

• SUSE was an early adopter on z Systems.• Only SUSE fulfilled all technical requirements ( fibre channel protocol ).• Some SUSE guys were working in the IBM Lab.• SUSE support was always excellent.• Installation process and customizing the SUSE Linux Enterprise on z went

smoothly; no reason to change the distribution.• SUSE headquarter is in Nuernberg; we are located in Nuernberg, too.

An IFL is not a special hardware, it´s a classic mainframe processor with limited usage by microcode.

An IFL can be used for z/VM and Linux only. It can´t be used for general purpose reasons ( = z/OS ). This limit helps to save money.

The latest z Systemsis a z13. It uses 8-core technology and a clock rate of 5.0 GHz.

IFL = Integrated Facility for Linux.

Why Databases on z Systems ?

Consolidating databases Oracle and DB2 to save license costs.

Pricing for Oracle and DB2 is related on number of cores.

With z Systems you need less cores than in distributed systems to runthe same workload. This fact helps to save money.

The mainframe is optimized to handle IO´s. Best response times.

Why Linux on z Systems ?

Linux is a modern and plattform independent operating system.

The combination of IBM z13 and Linux on z Systems is ideal to develop high availability state-of-the-art solutions and applications.

Zentrale Systeme | Oliver Röthinger 11/02/2015 1 von X

Conclusion

Reducing IT budget.

Scalability ( Using the “White Space” ).

Simplifying administration and maintenance.

Dealing more systems with fewer people.

Smaller footprint and homogenous infrastructure.

Flexibility ( faster provisioning of new Linux systems ).

Reuse of resources.

Zentrale Systeme | Oliver Röthinger 11/02/2015 1 von X

Less hardware helps to avoid outages.

Simplifies troubleshooting and debugging.

Maximum throughput with internal mainframe connections;Minimized latency times.
