Problems in 2004-Big intel based server farms with Red HatEC12-Datacenter run out of space- Footprint of server farms very high-High energy usage- No virtualisationZentrale Systeme Oliver Röthinger11/02/20151 von X
The Solution: Linux on z SystemsEC12- We already had a mainframe-We had knowledge of z/VM and Linux- It was simple to install and provide thefirst Linux on z Systems- The pilot system fulfilled all requirementsfor developmentZentrale Systeme Oliver Röthinger11/02/20151 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 Röthinger11/02/20151 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 (EvaluationAssurance Level 5 Security Classification) if it s using RACF.Zentrale Systeme Oliver Röthinger11/02/20151 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 Röthinger11/02/20151 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 Röthinger11/02/20151 von X
Back to 2004Decision 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 wentsmoothly; no reason to change the distribution. SUSE headquarter is in Nuernberg; we are located in Nuernberg, too.Zentrale Systeme Oliver Röthinger11/02/20151 von X
Hardware Environment at Sparda-Datenverarbeitung e.G. 2 datacenters with 10km distance between 2 x z13 systems each18 IFLs9 CPs15 ZIIPs1 TB memory 2 x DS8870 systems with PPRC880 TB usable storageZentrale Systeme Oliver Röthinger11/02/20151 von X
IFL Integrated Facility for Linux.An IFL is not a special hardware, it s a classic mainframe processor with limited usage bymicrocode.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 uses8-core technology anda clock rate of 5.0 GHz.Zentrale Systeme Oliver Röthinger11/02/20151 von X

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.Zentrale Systeme Oliver Röthinger11/02/20151 von X

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 develophigh availability state-of-the-art solutions and applications.Zentrale Systeme Oliver Röthinger11/02/20151 von X
ConclusionReducing 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 Röthinger11/02/20151 von X
ConclusionLess hardware helps to avoid outages.Simplifies troubleshooting and debugging.Maximum throughput with internal mainframe connections;Minimized latency times.Highest security. Network sniffing is very difficult.Simple methods to handle a disaster recovery.z/VM with SUSE Linux Enterprise Server is the most effectivecombination for our company.Zentrale Systeme Oliver Röthinger11/02/20151 von X
The FutureSystem automation for all Linux on IBM z Systems; end to end automationSimplifying maintenance. SUSE Manager could be an option.Three site solution for disk environment to switch the location withoutoutages.Ongoing provisioning of new Linux on z Systems workloads.Zentrale Systeme Oliver Röthinger11/02/20151 von X
