Server Consolidation with Virtualization
The migration of application architectures to thin-client architectures, the rapid introduction of four generations and multiple editions of Windows servers and the growth of Linux have swept across IT organizations in successive waves over the last ten years. IT has started to regain the upper hand in the battle against costly, inflexible and disorderly infrastructure. First, IT organizations have generally centralized their IT infrastructure into fewer locations for better visibility. Second, they are adopting a new generation of infrastructure technologies and methodologies including server consolidation. This paper discusses server consolidation options and considerations using VMware ESX Server on IBM eServer BladeCenter and IBM eServer xSeries 445 hardware. Systems management options using VMware VirtualCenter, VMotion, P2V Assistant, and IBM Director with VMM are also discussed.
