Resources that you can monitor

Edit online

You can use IBM Spectrum Control to monitor storage systems, servers, hypervisors, fabrics, and SAN switches. Information about these top-level resources includes information about their internal resources and related resources. Internal resources are components that exist in a top-level resource. Related resources are external to a top-level resource, but are related to it through assigned storage, a network connection, or virtual hosting.

Information about object storage systems includes information about their object resources and related resources. Object resources are resources in an IBM Storage Scale cluster, such as accounts and containers, that enable the cluster to be used as an object storage system.

Icon legend: Each resource that you monitor with IBM Spectrum Control is represented by an icon for easy identification. View the following information to see the icons that are associated with each resource.

Fabrics

A fabric is a network of hubs, switches, adapter endpoints, and connecting cables that support a communication protocol between devices. The following table shows the internal resources and related resources that you can monitor for fabrics.

Table 1. Fabric resources that you can monitor
Fabric icon	Internal resources	Related resources	*Connected resources (to ports)
Physical fabric Virtual fabric	Logical switches Physical switches Inter-switch connections Blades Ports Zone sets	Hypervisors Servers Storage systems NPV switches (Cisco switches in NPV mode and Brocade switches in Access Gateway mode) Discovered ports	All monitored resources that are connected to ports, plus the following resources: Unmanaged resource. The name is determined from a fabric zone alias. Unmanaged resource. The name is determined from a storage system's mapping to a host. Unmanaged resource. The name is determined from one of a storage system's mappings to a host when multiple mappings are found.
*Connected resources (to ports): The icons for any resources that are managed by IBM Spectrum® Control and connected to a port are shown in this column. Icons are also shown for connected resources whose names are known from a fabric zone alias or a storage system's mapping to a host (host connection) but are not currently being managed. If both a fabric zone alias and a storage system's mapping to a host are found for the same unmanaged resource, the fabric zone alias is shown as the name.

Hypervisors

A hypervisor is a layer of software or a physical device that manages multiple, virtual instances of operating systems on the same hardware. Hypervisors that you can monitor include VMWare vSphere data sources such as ESX, ESXi, and vCenter servers. If a hypervisor is part of a cluster, information about that cluster is also available.

The following table shows the internal resources and related resources that you can monitor for hypervisors.

	Controllers Disks Data stores Virtual machine that is associated with an agentless server Virtual machine that is associated with a Storage Resource agent Virtual machine that was discovered, but isn't associated with an agentless server or Storage Resource agent	Storage systems Fabrics Switches Cluster

Servers

A server is a computer or host that is connected to a network and provides an access point to that network. If a server is part of a cluster, information about that cluster is also available. You can monitor the following internal resources and related resources for servers.

Storage systems

A storage system is a device, such as a Redundant Array of Independent Disks (RAID) controller that creates and manages other storage devices. A storage virtualizer is a storage system that virtualizes storage space from internal storage or from another storage system.

Storage systems can be configured for block storage, file storage, a combination of block and file storage, or a combination of file and object storage. The method that a storage system uses for managing data determines the internal resources or object resources that are monitored.

The following tables show the internal resources, object resources, and related resources that you can monitor for block, file, and object storage systems.

Block storage systems

Switches

A SAN switch is a network infrastructure component to which multiple nodes attach. In IBM Spectrum Control, you can monitor Fibre Channel (FC) switches. The following table shows the internal resources and related resources that you can monitor for switches.

Table 7. Switch resources that you can monitor
Switch icon	Internal resources	Related resources	*Connected resources (to ports)
Physical switch Logical switch	Inter-switch connections Blades Logical switches Physical switches Ports	Fabrics Hypervisors Servers Storage systems Switches Discovered ports	All monitored resources that are connected to ports, plus the following resources: Unmanaged resource. The name is determined from a fabric zone alias. Unmanaged resource. The name is determined from a storage system's mapping to a host. Unmanaged resource. The name is determined from one of a storage system's mappings to a host when multiple mappings are found.
*Connected resources (to ports): The icons for any resources that are managed by IBM Spectrum Control and connected to a port are shown in this column. Icons are also shown for connected resources whose names are known from a fabric zone alias or a storage system's mapping to a host (host connection) but are not currently being managed. If both a fabric zone alias and a storage system's mapping to a host are found for the same unmanaged resource, the fabric zone alias is shown as the name.
