Host Capacity & Utilization
Explore your data center using APTARE 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.
In the report’s scope selector, several widgets enable special filtering of the report’s output:
• Host Type - 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.
• SAN-attached hosts only - SAN-attached hosts only - 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.
Host
The name of the host utilizing the storage. Click on a Host name link to view the 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.
Allocated Capacity
The total capacity of all Volumes both free and used that has been given to the host. When there is a significant discrepancy between the Allocated Capacity and the Seen by Host, it is an indication that there may be storage that can be reclaimable.
# of Used LUNs
LUNs that are currently used by the host. Click on this number to launch the 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. Click on the number link to view the Host Utilization Detail.
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.
