Virtualization on System z offers industry-leading and large-scale proven1 Cloud and IT optimization capabilities to drive down the costs of managing and maintaining the tremendous proliferation of servers in today’s technology infrastructures.
System z provides virtualization together with an extensive set of service management capabilities, including automated performance optimization and problem management, to help lower and control costs and providing secure IT services.
Virtualization Highlights
- Large-scale consolidation onto a single System z server – host more servers per core
- Reduce floor space requirements, drive down software license fees and save up to 75% on energy costs compared to virtualized x86 alternatives
- Virtualize and share all resources: processor, memory, network, I/O, cryptographic features
- Virtualization combined with protection of sensitive data and improved business continuity / disaster recovery
The zEnterprise System allows IT organizations to consolidate multiple systems and software stacks on a single platform, deploying an integrated hardware platform that brings System z and distributed technologies together.
Virtualization technologies supported on System z servers include the Processor Resource/System Manager (PR/SM) and the z/VM virtualization software.
- The PR/SM is integrated with all System z servers and allows dividing the servers into logical partitions (LPARs). Each LPAR is assigned a dedicated portion of the available physical resources. The resources can be shared across LPARs or dedicated to a particular LPAR.
On the latest System z models, you can create up to 60 logical partitions, running z/OS, z/VM, Linux®, Transaction Processing Facility (TPF) and/or z/VSE on a single System z server. - The z/VM virtualization software allows running up to hundreds, even thousands, of virtual servers from a single point of control, providing an impressive horizontal scalability and enormous opportunities for cost saving and enormous opportunities for cost saving through consolidation onto a single System z.
z/VM is designed for rapid server deployment and provisioning and enables new virtual servers in real time, providing support for multiple diverse workloads in a protected and isolated environment.
z/VM offers the highest levels of resource sharing—including the over-commitment capabilities for processors and memory, cooperative memory management, I/O bandwidth and system availability, resulting in nearly 100 percent utilization of the system resources nearly 100 percent of the time.
From simple multitasking to logical partitions to complete simulation of virtual hardware and operating environments, the System z virtualization capabilities provide mature and sophisticated virtualization technologies.
That makes System z an obvious choice for cloud computing with massive scalability, superior user experience, and great economics.
