Host Capacity & Utilization
Explore your data center using customizable report templates or by using parts of your IT infrastructure as entry points. Use Search to find reports, templates and dashboards across the portal.
Use the Reports tab to examine the catalog of templates, dashboards and reports - organized by products along with user-created, and system folders. This report is located here:
Use the Host Capacity and Utilization report to view an overview of host utilization to determine if there's contention for storage. Typically, once you've reviewed this high-level report, you'll want to access the details reported by the Host Utilization Detail.
See Host Utilization Detail .
In the report's scope selector, several widgets enable special filtering of the report's output:
- Use this selector to include virtual servers in this host-based report: VM Server, VM Guest, VIO Server, VIO Guest, Oracle Container, Oracle Zone, Hyper-V Server, Hyper-V Guest, or Other.To view a similar report for VM Guests, see the VM Summary report.
- - Check this box if you want to see data for only SAN-attached hosts. When this box is not checked, the report will include VM Guests and hosts that have been collected by other IT Analytics products, such as Backup Manager or Virtualization Manager.
Table:
Column name | Description |
|---|---|
|
Host |
The name of the host utilizing the storage. Click on a Host name link to view the details. See Host Utilization Detail . |
|
# of Allocated LUNs |
The number of LUNs that have been allocated to this host. Click on this number to launch the LUN Utilization Summary. See LUN Utilization Summary . |
|
Allocated Capacity |
The total capacity of all Volumes both free and used that has been given to the host. |
|
# of Used LUNs |
LUNs that are currently used by the host. Click on this number to launch the LUN Utilization Summary. See LUN Utilization Summary . |
|
Seen by Host |
The sum of all SAN capacity actually deployed or accepted by the host. This is the storage that the host has been allocated and is using--but this use could be as simple as adding the storage to a volume group. It does not mean that the server has that storage mounted. Mounted storage is reflected in Total DAS/SAN. |
|
# of Arrays |
The total arrays associated with this host. Click on the number to launch the Array Capacity and Utilization. |
|
Related Hosts |
Hosts that are related to this host via clustering--they have multi-pathing to the same LUNs for fail over. |
|
# Volumes | |
|
SAN/DAS |
The number of SAN/DAS volumes. |
|
NAS |
The number of NAS volumes. |
|
At Risk |
The number of host volumes that are at risk of reaching capacity, based on configured thresholds. |
|
Volume Capacity | |
|
Shared |
Represents the capacity that is shared by related hosts. |
|
Unshared |
Capacity that is not shared by related hosts. |
|
Total DAS/SAN |
Total of Shared and Unshared volume capacity. |
|
DAS/SAN |
DAS/SAN storage capacity for this host. |
|
NAS |
Total capacity of external, mounted filesystems (estimated). |
|
Volume Usage | |
|
DAS/SAN |
This is the actual amount of SAN/DAS storage used by the host. This may include shared capacity within the cluster. |
|
NAS |
The sum of currently allocated storage associated with external, mounted filesystems. The same NAS storage may be accounted for in multiple external filesystem mount points, resulting in double counting. |
