  • Virtualization ups ante on server hardware choices

    In our fifth issue of Virtual Data Center, Richard Jones explains how choices about whether to go with rackmount or blade servers should be dictated by four components of your environment: CPU, memory, storage and network bandwidth. Joe Clabby then e... 

  • hardware emulation

    Hardware emulation is the use of one hardware device to mimic the function of another hardware device.  Microsoft's Hyper-V includes hardware emulation because the Integration Services can only be installed on certain guest operating systems. 

  • server hardware degradation

    Server hardware degradation is the gradual breakdown of the physical parts of a server. 

  • host virtual machine (host VM)

    A host virtual machine is the server component of a virtual machine (VM), the underlying hardware that provides computing resources to support a particular guest virtual machine (guest VM). 

  • server virtualization

    Server virtualization is the masking of server resources, including the number and identity of individual physical servers, processors, and operating systems, from server users.

About Server hardware and virtualization

Once you decide to take on a server consolidation project using virtualization, you face a host of data center virtualization infrastructure challenges, including server hardware choices, network optimization, the right processors and memory capacity. You should consider which server would be the best virtualization platform for your environment -- blade servers, rackmount servers, legacy mainframe system or cloud computing platforms -- in terms of the virtualized workloads you will deploy, your data center footprint, and data center power and cooling requirements. You also want an adequate number of networking interface card (NIC) slots and host bus adapters (HBAs) and you need to choose the best networking options for virtual machine traffic, including PCI express, InfiniBand, Ethernet, of Fibre Channel. Choosing the right CPUs and server memory capacity for virtualization is also necessary. This section on server hardware choices for data center virtualization helps you weigh server hardware options and features in terms of cost, performance, reliability, support, interoperability and other factors to optimize server performance and server efficiency. You will learn which server hardware products and features are best suited for production environments, test and development, disaster recovery, high performance computing, and cloud computing, and how to optimize memory, CPU, networking, server configuration and management and virtualization hardware support.
