Considerations for deploying on a virtual machine

Infrastructure Management can be installed and run on a VMware virtual machine (VM).

When deploying the product on VMs, be aware that additional overhead exists because resources are shared across VMs. The same performance that is possible running applications on a physical computer is not possible on VMs. However, VMs offer more flexibility and ease of administration for some aspects, such as high availability and backups. 

Consider the following VMware best practices:

  • The Integration Service node(s) should be excluded from VMware HA if you are using the out-of-the-box active/active configuration, because PATROL Agents will automatically switch to their secondary location if the primary location is interrupted for any period of time.
  • You must reserve the Compute (CPU and memory) resources for the VM on which BMC TrueSight Infrastructure Management Server or any of its components are running to guarantee optimal performance. You must also ensure that you do not use the shared option.
  • You must use the Thick Provision Eager Zeroed disk type for the Infrastructure Management server. The Thick Provision Eager Zeroed disk provides the advantages of clustering features such as fault tolerance.
  • Use only two to three virtual machine snapshots in a chain. BMC recommends that you avoid using the single snapshot for more than 72 hours. You can either delete the snapshot or consolidate it. For more information, see http://kb.vmware.com/kb/1009402.
  • Enable NIC teaming.
  • Use a VMware paravirtual NIC adapter for optimized performance.
  • For ESX storage, ensure that you use dedicated disk storage all virtual machines; avoid sharing disk storage. See Hardware-requirements-to-support-small-medium-and-large-environments for storage requirements.
  • Configure Jumbo frames for the storage adapter.
  • Reserve the resources that are allocated for the virtual machine on which the BMC applications are installed.
  • Periodically monitor the CPU usage of the host.
