Why should you attend Innovate 2013? Deep, technical education is one reason to attend, and one way you'll learn to stay ahead of the competition. This year’s Innovate includes System z Essential Sessions which features a Technical Exchange session stream with an entire track dedicated to System z, as well as many related sessions in other tracks. See what else is in store with regards to Innovate 2013 at:
One session in particular is a must see for all those people who run Linux on System z:
2049 Server Consolidation on Linux for System z: Real success
Linux on System z combines the advantages of the IBM mainframes with the flexibility and open standards of the Linux operating systems. Most Linux on System z guests take advantage of an additional virtualization level, z/VM. z/VM operates inside an LPAR, like any other mainframe operating system. This provides two levels of Linux virtualization: based on hardware, and based on a hardware-assisted hypervisor. Reasons to run Linux as a guest on z/VM include sharing of resources, server hardware consolidation, virtualization, high performance communication among virtual machines, as well as the ability to exploit all of the advantages of System z such as reliability, availability and serviceability (RAS).
On October 12, 2011, IBM announced the z/VM version 6.2. This newest release introduced single system image (SSI) and live guest relocation (LGR), a first for the mainframe. SSI is a separately orderable priced feature of the z/VM version 6.2. This new version of z/VM introduces multisystem clustering technology that allows up to 4 z/VM instances in a single system image cluster. This is important because it offers clients an attractive alternative to vertical growth by adding new z/VM systems. In the past, this capability required duplicate efforts to install, maintain, and manage each system. With SSI, these duplicate efforts are reduced or eliminated.
There is an ever-increasing demand for IT resources and tighter budgets. Smarter computing addresses this challenge through IT transformation. Virtualization is a key element of transformation that helps reduce sprawling IT landscapes. Virtualization helps provide flexibility to meet user demands for security, availability, scalability and manageability of IBM System z.
But what are the business benefits of using this new z/VM?
