Investigating Director - Ports

The data displayed in the dashboard reflects values for the VPLEX storage over the selected time range. This walkthrough describes the contents of each of the tabs.

To explore a director:
1
On the navigation panel, under Dashboards, click Storage & SAN > Storage Explorer.
2
In the Storage Explorer dashboard, click the director name in the Director table.
3
In the Summary tab, review performance in terms of key metrics.
•
Details. Displays physical details about the selected director.
•
Charts. Plot values over the time period for these metrics, if available: Ops Rate, Data Rate, % Busy, Frontend Abort, and Average Queue Depth.
•
Alarm Summary. Displays alarms on the selected director. To investigate further, click an alarm. See Assessing Storage Alarms.
4
In the Ports tab, Shows the history performance data of the port, including Ops Rate, Data Rate, and Latency.
To explore a port:
1
On the navigation panel, under Dashboards, click Storage & SAN > Storage Explorer.
2
In the Storage Explorer dashboard, click the director name in the Port table.
3
In the Summary tab, review performance in terms of key metrics.
•
Details. Displays physical details about the selected port.
•
Charts. Plot values over the time period for these metrics, if available: Ops Total, Bytes Read, Bytes Write, Read Latency, and Write Latency.
•
Alarm Summary. Displays alarms on the selected port.To investigate further, click an alarm. See Assessing Storage Alarms.

Investigating a Virtual Volume

A Virtual Volume represents a logical SAN block storage device on an VPLEX array that can be exposed for mapping to a server. The data displayed in the dashboard reflects metric values for the Virtual Volume over the selected time range. This walkthrough describes the contents of each of the tabs.

To explore a Virtual Volume:
1
On the navigation panel, under Dashboards, click Storage & SAN > Storage Explorer.
2
In the Storage Explorer dashboard, click the Virtual Volume in the Virtual Volumes Detail table.
3
In the Summary tab, review performance in terms of key metrics.
•
Details. Displays the Virtual Volumes’s status, physical details, parent device and capacity metrics.
•
Ops Chart. Shows the history Ops Rate of the virtual volume.
•
Data Rate Chart. Shows the history Data Rate of the virtual volume.
•
Latency Chart. Shows the history Latency of the virtual volume.Alarm Summary. Displays alarms on the VPLEX array.
•
Alarm Summary. Displays alarms on the selected virtual volume. To investigate further, click an alarm. See Assessing Storage Alarms.
4
In the Frontend Topology tab, displays the dependency mapping from virtual machines to the virtual volume. Click a cloud node to display the network dependency mapping from VM disks to the virtual volume.
5
In the Backend Topology tab, displays the dependency mapping from the virtual volume to the destination LUNs. Click a cloud node to display the network dependency mapping from the virtual volume to the destination LUNs.

Investigating a Storage Volume

The data displayed in the dashboard reflects values for the selected storage volume over the selected time range. The Storage Volume dashboard has only one tab.

To explore a storage volume:
1
On the navigation panel, under Dashboards, click Storage & SAN > Storage Explorer.
2
In the Storage Explorer dashboard, click the Storage Volume in the Storage Volumes Detail table.
3
In the Summary tab, review performance in terms of key metrics.
•
Details. Displays the storage volume’s status, physical details, parent device, and size if available.
•
Charts. Plots values for Data Rate, Data Read Rate, and Data Write Rate.
•
Alarm Summary. Displays alarms on the selected storage volume. To investigate further, click an alarm. See Assessing Storage Alarms.
4
In the Topology tab, displays the dependency mapping from virtual volumes to the storage volume, and the dependency mapping from the storage volume to destination LUNs. Click a cloud node to display the network dependency mapping from the storage volume to destination LUNs.
