  • Quickspecs Proliant Essentials Server Migration Pack Overview
    RETIRED: Retired products sold prior to the November 1, 2015 separation of Hewlett-Packard Company into Hewlett Packard Enterprise Company and HP Inc. may have older product names and model numbers that differ from current models. QuickSpecs ProLiant Essentials Server Migration Pack Overview The ProLiant Essentials Server Migration Pack radically simplifies server consolidation projects. Server Migration Pack (SMP), a companion product to the Virtual Machine Management Pack, automates the manual processes required for a physical server to virtual machine (P2V) migration. SMP raises the bar on P2V automation, so that a typical migration process can be completed in a matter of minutes. The SMP's advanced migration technology also provides the ability to support virtual machine to virtual machine (V2V) conversions. V2V provides the ability to covert Virtual Machines between different underlying virtualization layers including: VMware ESX Server, VMware GSX Server, and Microsoft Virtual Server 2005. Systems Insight Manager and the ProLiant Essentials management software provide a complete tool set for server consolidation projects. Using HP SIM and the Performance Management Pack, users can easily identify underutilized servers in the datacenter that are candidates for consolidation. Once these systems are identified, SIM and the Server Migration Pack provide an easy to use physical to virtual (P2V) migration capability. Available Packs and Purchase Information Licensing and Packaging General Licensing Information One license is required for every physical server that is migrated into a virtual machine (P2V). One license is also required when a virtual machine is migrated from one virtualization layer to a different virtualization layer (V2V). The Server Migration Pack (SMP) licensing model is based on the concept that one license is consumed per migration.

Virtualization is considered the core-computing layer of a cloud setup. All the problems a traditional data center environment like space, power, resilience, centralized data management, and rapid deployment of servers as per business need have been solved with the introduction of Hyper-V (a server virtualization solution from Microsoft). Now companies can deploy multiple servers and applications with just a click and they can also centrally manage the data storage.

  • Integrating Virtualization Technology Into Remote Labs: a Three Year
    AC 2009-318: INTEGRATING VIRTUALIZATION TECHNOLOGY INTO REMOTE LABS: A THREE-YEAR EXPERIENCE Peng Li, East Carolina University Page 14.771.1 Page © American Society for Engineering Education, 2009 Integrating Virtualization Technology into Remote Lab: A Three- Year Experience 1. Introduction and Background Many colleges and universities are facing rising enrollments while the budgets have not been increased proportionally. In our program, enrollment has gone up significantly in the past few years, especially in the distance education (DE) section. How to use the limited resources to deliver quality education effectively and efficiently becomes a real challenge. To deal with this challenge, we have experimented with different virtualization options in the past three years. This paper is a follow-up to the studies1,2 we presented at the previous ASEE conferences and summarizes our three-year experience. Virtualization technology allows multiple guest virtual machines to run simultaneously on a physical computer. The technology was first developed3 at IBM for mainframe systems in the 1960s. The first x86 virtualization product, “VMware Virtual Platform” was released by VMware Inc. in 19994. The year of 2009 is the 10th anniversary of this breakthrough. The x86 virtualization technology has gradually become more mature and stable since early 2000s5. Virtual machines were reportedly used for educational purposes in college computer labs as early as 20026,7,8. However, the technology has not been adopted broadly until recent years due to a few factors: 1) the early virtualization products were buggy and not very reliable; 2) the virtualization software packages were resource-demanding and costly. Therefore they were usually hosted on high-end machines in centralized on-campus computer labs.
