Linux on z Systems

Enterprise grade Linux with increased economics and qualities of service

The Linux environment benefits from the enormous capabilities of the IBM z Systems, IBM z/VM virtualization and IBM Wave for z/VM virtualization management technologies, providing an enterprise grade Linux platform for all kind of workloads - cloud, analytics, mobile, and much more – data center simplification, trusted operations and unrivaled economics. Benefits include:

Master IT complexity while improving economics and driving higher qualities of service with the Enterprise Linux Server. It can help you to reduce both cost of acquisition and cost of ownership. The Enterprise Linux Server can provide you the IT infrastructure for enterprise grade Linux deployments, including large scale consolidations that can dramatically reduce the cost of software licenses, and can help you to drive datacenter simplicity, trusted operations and unrivaled economics.

z/VM

z/VM Version 6 Release 3 - Virtualization with efficiency at scale

IBM z Systems and z/VM are designed to deliver an efficient, secure, adaptive and integrated IT infrastructure for enterprise grade Linux workloads that scale both horizontally and vertically at a low total cost of ownership. New economic efficiencies offer more throughput and capabilities with less impact to the IT budget.

z/VM 6.3 is the premier virtualization platform. It supports more virtual servers than any other in a single footprint for growing business demands and lower cost of service delivery. With its high level of security, you can put your trust z/VM to protect your most valuable information and thereby reduce organizational and reputational risk. Benefits include:

z/Transaction Processing Facility (z/TPF)

Transaction processing is a largely invisible back-end business computing function. Yet it is a key enabler of an enormous range of economic activities – from travel reservation and ticketing systems and electronic banking, to financial transactions and e-commerce. Transaction processing is and will remain a critical component of the world’s economic engine – responsible for handling trillions of transactions every year. The workload volume managed by major users of transaction-processing systems is enormous. The majority of high volume transaction processing applications run on mainframes and rely on operating systems such as zTPF.

z/VSE
