40th Anniversary - August 2, 2012
Forty years ago, on August 2, 1972, commercial use of virtualization
became a reality with the IBM announcement of VM/370. Virtualization
transformed the way we think about the underlying technology by
flexible dynamic server resources that help businesses run faster and
respond to customer needs more efficiently.
z/VM is built on design points that have stood the test of time and
remain essential to our customers today.
Share everything - z/VM's strength is its ability to share a limited set
of resources across many guest operating environments. Examples include
CPU, memory, I/O adapters, control units, disk devices, cryptographic
cards and network cards. See how
Endress+Hauser maximizes availability
and resiliency in a z/VM environment with Linux.
Highest levels of utilization - z/VM can achieve nearly 100% utilization
of resources nearly 100% of the time.
Run multiple diverse mixed workloads with isolation - z/VM is designed
run multiple workloads concurrently in a shared environment. It
Linux on System z, z/OS, z/VSE, z/TPF and z/VM itself. Within each of
these environments diverse mixed workloads can be run. In addition,
production workloads can run on the same System z server as development,
test, and quality assurance workloads. See how
Embasa runs a diverse workload to improve SAP data flows.
Flexible workload balancing - Move Linux virtual servers to available
resources in addition to the long-standing capability to non-disruptively
add resources such as CPU, I/O, networking and memory. Live Guest
Relocation provides the ability to move virtual servers to another LPAR
on the same or on a different System z without disruption to the
business. See how
a healthcare company provisions hundreds of virtual
servers in an automated environment.
Multi-system virtualization - Up to four z/VM instances can be clustered,
serviced, and administered as one in a Single System Image.
Highest server consolidation ratio in the industry - z/VM supports more
Linux virtual servers than any other platform in a single footprint. See
EFiS EDI Finance Service AG used z/VM to successfully consolidate
their IT environment and significantly improve performance levels.
Today's z/VM helps businesses simplify their infrastructure and lower IT
costs. z/VM is based on a 40-year-old
technological breakthrough which
remains as critical today as ever. It continues to help reduce sprawling
IT and provide flexibility to meet customer demands with the
underpinnings of the security, availability, scalability, and
manageability of System z.
