Linux on System z: simple, scalable, available, secure.
Linux on System z servers can do more with less, helping IT organizations to eliminate server sprawl and complexity and to build a cloud environment. Linux on System z combines the open standards of Linux with the unmatched power of IBM System z server and virtualization technlogies.

Linux on System z can help on a smarter IT infrastructure that:

  • Improves IT optimization for efficiency and effectiveness
  • Provides advanced virtualization for greater flexibility, scalability and simplicity
  • Helps you meet growing security, compliance and regulatory demands
  • Supports energy efficiency and environmental initiatives

The cost benefits

Linux on System z can help lower your IT costs with support for massive consolidation, running up to thousands of virtual Linux servers concurrently and ensuring isolation and protection of each virtual server environment. Consolidation of distributed servers and new workload deployment onto a single IBM zEnterprise server provide following cost reduction opportunities:

  • Software licensing
    Linux on System z can fully leverage the IBM System z virtualization capabilities, for example, a z196 can support up to 50 distributed servers on a single core, up to thousands on a single system1. Software licensing costs can be reduced due to the fact that Linux software is usually priced on a per-core basis.

  • Administration and management
    Linux on System z allows to run many virtual Linux servers onto a single physical server, which can mean less labor for system management and maintenance. The centralized system management and autonomic compute capabilities can also help cut down on errors and workload-balancing tasks.

  • Business continuity
    Linux on System z can scale up and out to meet spikes in server activity, helping to minimize costly transaction delays and potentially devastating system crashes. Application continuity, avoiding planned outages, is provided with the Live Guest Relocation possibility available with the z/VM 6.2 virtualization software. And, with a suite of built-in features, System z servers can rapidly respond to, or even anticipate, threats to system health.

  • Energy consumption
    Linux on System z allows for fewer servers and networks which help on savings in physical space, air conditioning and electricity costs. In practical terms, this equates to replacing a room full of servers with a single, refrigerator-sized System z server.
