Automating virtual workload mobility with IBM Vmready

  1. 1. IBM Systems and TechnologySolution Brief Automating virtual workload mobility with IBM VMready IBM PowerVM with VMready Ten years ago, data center networks were simpler. Workloads were static, Highlights and applications ran on operating systems residing on dedicated physical servers. Many data centers are now implementing server virtualization to ●● ● ● Simplifies network control and visibility for improve utilization of existing infrastructure, which makes it possible to PowerVM® live partition migration implement new IT services quickly and expand the capacity of existing Prevents security breaches and service ●● ● ● services.

However, as sys- ●● ● ● Enables virtualized networks that are secure, dynamic and easier to manage tems become more consolidated through virtualization, the network becomes more congested, particularly at the server network interfaces and server edge switches. Virtualization places new demands on the network and new challenges for server and network administrators: ●● ● Each new logical partition (LPAR) created for a virtual workload needs to be configured and maintained like any physical machine, but managing the network state of workload before, during and after a live partition migration is difficult. ●● ● When an LPAR is migrated to a different physical host, both server and network administrators need to reconfigure port and network states on the LPAR, the network switch and at both the source server and the destination server.
