About storage to application visibility using InfoScale Operations Manager

Datacenters adopt virtualization technology to effectively use the IT-infrastructure and substantially reduce the capital and operational expenditures. If you have adopted virtualization technology in your datacenter, InfoScale Operations Manager provides you an efficient way of discovering and managing your virtual storage and infrastructure assets.

In your datacenter, InfoScale Operations Manager helps you view the following relationships:

  • Applications in your datacenter that InfoScale Operations Manager manages and the virtual hosts on which they are running.

  • Physical storage in your datacenter that is exported to the virtual machines.

InfoScale Operations Manager supports the following virtualization technologies:

  • VMware

  • Microsoft Hyper-V

  • Kernel-based Virtual Machine (KVM)

In the VMware virtualization technology, a designated Control Host discovers the VMware vCenter Server in the datacenter. This discovery displays those ESXi servers that VMware vCenter Server manages, and the virtual machines that are configured on the ESXi servers.

For more information, refer to the InfoScale Virtualization Guide - Linux on ESXi.

For Microsoft Hyper-V, InfoScale Operations Manager discovers Hyper-V virtual machines and their correlation with the Hyper-V server. It also discovers the storage that is provisioned to the guests, and its correlation with the virtual machine and Hyper-V server. The Hyper-V guest (with or without VRTSsfmh RPM), when added to InfoScale Operations Manager Management Server domain, provides storage mapping discovery.

For Kernel-based Virtual Machine (KVM), InfoScale Operations Manager discovers KVM virtual machines on the Linux host if the KVM modules are installed, and configured. InfoScale Operations Manager discovers basic information about only running virtual machines. For example, virtual machine name, CPU, and so on.

For more information, see the InfoScale Operations Manager documentation.
