Linux on System z: simple, efficient, secure.
Linux on System z servers can do more with less, providing IT organizations a robust and effective workload deployment platform for consolidation, to eliminate server sprawl and complexity, as well as re-deployment and new workload deployment. Linux on System z benefits from the open standards and the unmatched power of the IBM System z server and z/VM virtualization technologies.
Linux on System z can help on a smarter IT infrastructure that:
- Provides efficiency at scale on a single physical server
- Delivers industry-leading virtualization for effective deployment
- Enables flexible delivery of services through a private cloud
- Delivers real-time information and insight from data
- Provides unmatched security and reliability
The cost benefits
Linux on System z can help lower your IT costs by running up to hundreds of virtual Linux servers concurrently with ensured isolation of each virtual server. Consolidation of distributed servers and new workload deployment onto a single IBM System z server provide cost reduction opportunities in:
- Software licensing
Linux on System z can fully leverage the IBM System z server and z/VM virtualization capabilities, for example, with a zEnterprise BC12 (zBC12) you can run up to 40 virtual Linux servers or more on a single IFL core or hundreds in a single footprint1. 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 running many virtual Linux servers onto a single physical server. A consolidation onto System z results in reduced numbers of servers and network components, and fewer components lead to a simpler and less complex IT infrastructure which requires less administration and maintenance efforts. In addition, with the new z/VM Version 6 Release 3 you can get additional horizontal scalability, meaning that more virtual Linux servers can be managed within one z/VM instance.

- Security and 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 available with the Live Guest Relocation feature of the z/VM 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 and floor space requirements
Linux on System z allows for fewer servers and networks which help on savings in physical floor space, air conditioning and electricity costs. In practical terms, this equates to replacing a room full with many, many servers with a single System z server.
