  • The faster, safer way of VM resource provisioning

    As with many other facets of virtualization, VM resource allocation is becoming automated. Find out what tools you can use for automated provisioning.

  • Cluster I/O fencing explained

    I/O fencing helps prevent file system corruption, but do you know how it works and when to use it?

  • The perils of inaccurate resource allocation

    Mistakenly over-allocating or under-allocating VM resources could cost your data center -- both in wasted budget and in compromised performance.

Expert Answers

  • How can I calculate a VM's resource requirements?

    You try to avoid overallocating VM resources, but requirements aren't always obvious. This is when application benchmarking comes in handy.

  • Comparing RHEV features to vSphere and Hyper-V

    Aside from the price tag, do you know what separates these popular hypervisors? RHEV features many of the same capabilities as its two chief rivals.

  • Guidelines for taking picture-perfect VM snapshots

    Virtual machine snapshots can help organizations avoid lengthy downtime, but do you know when and how often you should create a snapshot?

  • Converting VMs from VMware to Hyper-V

    Find out how easy it is to make the transition from VMware to Hyper-V with SCVMM or the Microsoft Virtual Machine Converter.

  • How do you add and import VHD files?

    Need to import VHD files into Hyper-V, but don't know how to go about it? PowerShell to the rescue!

  • The limited capabilities of VM backup tools

    Neither SAN-based VM backups nor VCB can do it all. When you understand the scope of each method, you'll make a better disaster recovery decision.

  • VM snapshots: What are you doing wrong?

    You've done everything right -- even quiesced the VM -- but you're still experiencing a snapshot error. What's causing the failure?

  • How should we introduce a second hypervisor?

    Multi-hypervisor environments are becoming more common, but IT shops usually stick with one hypervisor for production.

  • For VM backups, remember conventional wisdom

    Choosing the wrong VM backup methods and tools could cause major problems in your infrastructure. Avoid the headaches by remembering the basics.

  • Setting a disaster recovery testing schedule

    While plans will vary from business to business, there are some important guidelines for determining how often to perform a disaster recovery test.

  • Should we add a second hypervisor?

    Is it time to add a second hypervisor? Licensing, vendor lock-in and technology updates can all play a part in the multi-hypervisor decision.

  • What problems come with multi-hypervisor management?

    Adding a second hypervisor means adding complexity into the IT environment. Know the challenges before you deploy.

  • Does resiliency dictate hypervisor performance?

    Server availability is not the primary determinant of hypervisor performance, but when coupled with software updates, can keep it up and running.

  • Hypervisor workloads and resources: A balancing act

    Hardware and software affect hypervisor performance, but what about workload distribution? How should you balance virtual and physical resources?

  • Ask the expert: How do I enable PowerShell remoting?

    Managing multiple systems from a remote location can help save admins time and money, but first, you need to enable PowerShell remoting.

  • Can we boost hypervisor performance with hardware?

    Software plays an important role in virtual infrastructure performance, but can you optimize performance by tweaking server configurations?

  • Differentiating between RHEV 3.1 and oVirt 3.1

    If you wonder about the difference between RHEV 3.1 and oVirt 3.1, you're not alone. We asked an expert to clear up any oVirt vs. RHEV confusion.

  • VirtualBox as a hypervisor alternative?

    On desktops, VirtualBox offers many core virtualization features, such as OS testing and VM creation. Could it function as a hypervisor alternative?

  • Do free hypervisors exist?

    Virtualization ultimately saves you money, but you need to front costs first -- or do you? We asked an expert to explain free hypervisor options.

  • Why store VMs on an SMB file share?

    Changes to Hyper-V and the SMB 3.0 protocol could make using an SMB file share the right decision for your environment.
