How Arctera InfoScale Operations Manager discovers hosts
Arctera InfoScale Operations Manager provides several ways to discover the hosts and their associations to storage resources and network devices. To discover the hosts and their connections to storage resources, you can either install an agent or use agentless capabilities.
Agent and agentless capabilities include the following:
| Discovery of the hosts using an agent, for the hosts that have Arctera InfoScale Operations Manager and Storage Foundation installed on them | An agent is a software package that runs on a host. It discovers the storage resources that are associated with a host and relays the information to Management Server. |
|---|---|
| Discovery of the non-Storage Foundation hosts using an agent, for the hosts that have Arctera InfoScale Operations Manager installed on them | Agent-based discovery is also used for the non-Storage Foundation hosts that have Arctera InfoScale Operations Manager installed on them. |
| Discovery of the non-Storage Foundation hosts using agentless discovery scripts, for the hosts that do not have Arctera InfoScale Operations Manager installed on them | Arctera InfoScale Operations Manager can discover a host by remotely accessing the host and then running the scripts that collect data. |
| The agentless discovery scripts access the host using SSH (for UNIX hosts) or WMI (for Windows hosts). | |
| Arctera InfoScale Operations Manager identifies this type of the host as an agentless host. |
Note: Agentless discovery is not supported on the hosts that have Arctera Storage Foundation or Arctera InfoScale Operations Manager installed.
Through each of these host discovery options, Management Server is the central point to which all of the discovered data flows. Figure: Arctera InfoScale Operations Manager components and discovery (basic) depicts the flow of data with each of the host discovery options. Figure: Arctera InfoScale Operations Manager components and discovery (virtualization servers and virtual machines) depicts how Arctera InfoScale Operations Manager discovers virtualization servers and virtual machines.

Managed host (MH(DH)) is the discovery host for SAN and NAS arrays. Managed host (MH+FI) discovers SAN switches if Fabric Insight Add-on is installed. Control Host (MH+CH) discovers agentless hosts (AH), VMware and LPAR servers and virtual machines. Management Server (MS) discovers managed hosts (physical hosts), Hyper-V virtualization servers, KVM, LDOMs, and Solaris Zones.
