Common Component Disk Tab Data

The Disks tab can be found on the following dashboards:

•
Member/Node
•
Pool
•
Aggregate
•
NASVolume.

The Disks tab displays the physical disks associated with the selected entity.

 
•
Top 5 Disks. Displays the top five disks with the highest average value for Ops Rate and the performance metrics most useful for this array or filer.
•
Disk Status Filter. Click to show only disks with the selected status in the Disk Details table.
•
Disk Details. For each disk, identifies its status, physical state, parent pool or aggregate, and Disk Size, and then displays current values for Ops Rate, % Busy, Average Queue Depth, Data Rate, and Latency. Click a Sparkline to plot metric values over the time period.
 
* 
NOTE: If a metric is not available for this particular array or filer, the column is not displayed.
The remaining columns provide the following details:
- Role. Displays the role played by the disk in the pool, such as disk or spare.
- RPM. Displays revolutions per minute as reported by the vendor.
- Disk Interface. When available, displays the type of interface, such as SATA or SCSI.
- Member. EqualLogic and Isilon only. Displays the name of the member node where the disk physically resides.
•
Alarm Summary. Displays alarms on disks.

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.
