PlateSpin® Recon from Novell is a server consolidation and capacity sophisticated workload analysis, planning and planning initiatives, and provides ongoing management of the real management solution that provides new levels physical resources—and costs— of intelligence, visual analysis and forecasting of your virtual infrastructure. for optimizing the data center. PlateSpin Recon: A Clear and Concise Picture of Your Data Center With broad, multiplatform support, PlateSpin Recon collects inventory and workload utilization statistics for a clear and concise picture of all the hardware and application services running in the data center, including how and when those resources are being used. PlateSpin Recon takes the guesswork out of complex server consolidation and capacity planning initiatives, and provides ongoing management of the real physical resources—and costs—of your virtual infrastructure. Figure 1. PlateSpin Recon provides advanced scenario modeling, trending, forecasting and planning capabilities to take the guesswork out of data center initiatives. Use powerful what-if modeling to determine optimal combinations of hardware and virtual hosts to ensure maximum resource utilization.

  • The Server Virtualization Landscape, Circa 2007
    ghaff@ illuminata.com Copyright © 2007 Illuminata, Inc. single user license Gordon R Haff Illuminata, Inc. TM The Server Virtualization Bazaar, Circa 2007 Inspired by both industry hype and legitimate customer excitement, many Research Note companies seem to have taken to using the “virtualization” moniker more as the hip phrase of the moment than as something that’s supposed to convey actual meaning. Think of it as “eCommerce” or “Internet-enabled” for the Noughts. The din is loud. It doesn’t help matters that virtualization, in the broad sense of “remapping physical resources to more useful logical ones,” spans a huge swath of Gordon Haff technologies—including some that are so baked-in that most people don’t even 27 July 2007 think of them as virtualization any longer. Personally licensed to Gordon R Haff of Illuminata, Inc. for your personal education and individual work functions. Providing its contents to external parties, including by quotation, violates our copyright and is expressly forbidden. However, one particular group of approaches is capturing an outsized share of the limelight today. That would, of course, be what’s commonly referred to as “server virtualization.” Although server virtualization is in the minds of many inextricably tied to the name of one company—VMware—there are many companies in this space. Their offerings include not only products that let multiple virtual machines (VMs) coexist on a single physical server, but also related approaches such as operating system (OS) virtualization or containers. In the pages that follow, I offer a guide to today’s server virtualization bazaar— which at first glance can perhaps seem just a dreadfully confusing jumble.

Warfield Senior Researcher and Analyst [email protected] © 2008 IBM Corporation Internet Security Systems Food for Thought Is “Virtual Reality” an oxymoron or is it the department of redundancy department and how could you tell? 3 Virtualization Technology, A Manifold Arms Race © 2008 IBM Corporation Internet Security Systems Introduction . Virtualization has been a hot topic in IT news. Frequent topic of discussion in user's groups. Products like VMware and Xen are making great advances. Hardware advances are improving virtualization capabilities. Malware like “blue pill” are worrying researchers. Virtualization is much older than all this. Virtualization is much broader than all this. Virtualization is much more pervasive than all this. 4 Virtualization Technology, A Manifold Arms Race © 2008 IBM Corporation Internet Security Systems Virtualization . Virtualization, in computer technology, is the process of grouping and dividing the resources of a computer system into multiple execution environments by applying one or more methodologies or technologies such as hardware or software partitioning, partial or complete machine simulation, and/or emulation. – Corollary 1: Virtualization should have no operational impact on applications running under virtualization. – Corollary 2: A normally operating application should experience no change to its operation when running under virtualization. A virtual machine environment is a virtualization in which an entire system is virtualized. – Corollary 1: A Virtual Machine Environment should have no operational impact on the system or applications running under virtualization. – Corollary 2: A normally operating system and its applications should experience no change to its operation when running under virtualization.
