Common Component Disk Tab Data

The Disks tab can be found on the following dashboards:

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.
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 VPLEX Storage

To gain a complete picture of the performance of a VPLEX storage device, you need to understand how its child components are performing.

This section covers the following topics:

Introducing VPLEX Virtualization Components Dashboards

The VPLEX Virtualization Components dashboard is a drill-down view that displays virtualization details about a selected VPLEX storage array, performance and capacity metrics, and alarms.

For information about each type of VPLEX Virtualization Components dashboard, see the following topics:
