The System z platform combined with its highly advanced operating systems offer capabilities that allow superior optimization of IT environment.
System z hardware(HW) that IT clients deploy can be configured and optimized to provide:
- High (near 100%) utilization of resources (CPU, IO, Memory, Network, etc..)
- The ability to scale up (vertically) so that:
- Clients can order System z server configured with processing power required to support existing workloads
- Additional processing power can then be activated on demand and when needed and turned off when it is no longer required
- Customer-initiated procedures can be used to upgrade and add processing power
- Near-linear horizontal scaling that can be achieved, if required, by parallel sysplex clustering of a set of system z’s:
- Data sharing can be implemented to allow 24/7 availability and superior scalability and flexibility
- Superior virtualization of the System z server to allow clients to define and provision virtual servers:
- Such servers are fully isolated and coexist to share the resources of the System z server
- They exhibit the characteristics of distributed servers without requiring dedicated dispersed hardware
- Such virtualization on System z is the most effective way to prevent server sprawl and best approach to control the cost and complexity of the IT infrastructure
- Simplified infrastructure that can be achieved by resource and data sharing among applications running on a single system z or a cluster of system z mainframes
- Greatly simplified and cost effective disaster recovery scenarios due to much fewer distributed servers involved
- Cost effective IT environment that meets the budgeting of the client data centers
