 Why Linux on System z
| | |
A dynamic infrastructure. Efficient. Green. Optimized
Rising cost pressures, new risks and security threats, higher IT service expectations and emerging technologies: these are the evolving forces that drive IT organizations to change and become more dynamic. |
Enter Linux on IBM System z. It can help transform your IT infrastructure into a dynamic infrastructure which is:
- Consolidated, cost-efficient and optimized
- Flexible, resilient and highly scalable
- Enabled for collaboration and transforms information into business insight
- Addressing growing security, compliance and regulatory demands
- Providing support for energy efficiency and environmental initiatives
Linux workload on System z can provide improvements to qualities of service, system management and performance, and when integrated with existing data and applications on z/OS, z/VSE or z/VM, it can naturally complement these environments. |
|
Linux on System z can help lower your IT cost, whether you are a small, medium or large enterprise. Linux on System z allows for massive consolidation, exploiting the leading capabilities of the System z servers to run multiple and mixed mission-critical & infrastructure workloads concurrently:
- Virtualization
- Manageability
- Connectivity
- Security
- Reliability and Availability
Linux on System z can be a boon to your bottom line in a variety of ways: |
Possible savings on staffing:
Consolidating multiple servers onto a single System z server running multiple virtual Linux servers can mean less labor required for system management and maintenance. The centralized system management and autonomic computing capabilities of Linux on System z can also help cut down on the errors and workload-balancing tasks that otherwise can eat up countless IT staff hours. |
Possible savings on software:
An IBM System z10 Enterprise Class (z10 EC) mainframe can reduce per-core licensing costs up to 30 to 1 compared to x86 environments1. That is due to the fact that a single System z server can run multiple Linux applications on a single engine and that Linux software is usually priced on a per-engine basis. |
Possible savings on business continuity:
Linux on System z can give you the ability to scale up and out–as required by your business change–to meet spikes in server activity, helping to minimize costly transaction delays and potentially devastating system crashes. With a suite of built-in features, System z servers can rapidly respond to, or even anticipate, threats to system health, helping to prevent budget-sapping downtime. |
Possible savings on hardware:
Linux running on System z can help you on your infrastructure simplification reducing IT complexity. The outstanding virtualization capabilities of System z can allow you to consolidate hundreds of Linux servers onto a single server and deploy these virtual servers in a matter of minutes. Maximum efficiency and value for your business through high utilization and fast internal connectivity. |
Possible savings on energy consumption:
Fewer servers and networks can mean savings in physical space and heating, air conditioning and electricity costs. System z enables energy efficient computing with its high utilization rates and leading technologies. The IBM System z10 Business Class (z10 BC) mainframe has the capacity of up to 232 x86 servers with 83% smaller footprint, up to 93% lower energy costs2. The differences are quantum – a refrigerator size box versus a full room of servers. |
|
1 Ratio of z10 EC processor cores to x86 processor cores will vary depending on the age and speed of the x86 processors and the workloads being run on them.
