Displays graphically the effectiveness of the QoS Plus feature for a collection of auto‑tiered LUNs.

Provides details about a collection of auto‑tiered LUNs in a Storage Domain. You can select up to 10 LUNs to analyze.

Name

Identifies the name that is assigned to the LUN.

LUID

Identifies the unique identifier of the LUN.

Priority Level

Identifies the assigned priority level of the volume at the time that it was created.

Premium: Indicates the highest priority for responding to requests in the processing queue
High: Indicates the next highest priority for responding to requests in the processing queue
Medium: Indicates an intermediate priority for responding to requests in the processing queue
Low: Indicates the next to lowest priority for responding to requests in the processing queue
Archive: Indicates the lowest priority for responding to requests in the processing queue

Capacity Disk Capacity

Identifies the amount of capacity that is allocated to the auto-tiered LUNs that reside on RAID 6 and RAID 10 storage tiers.

Performance Disk Capacity

Identifies the amount of capacity that is allocated to the auto-tiered LUNs that reside on RAID 5 and RAID 10 storage tiers.

Capacity SSD Capacity

Identifies the amount of capacity that is allocated to the auto-tiered LUNs that reside on RAID 5 and RAID 10 storage tiers.

Performance SSD Capacity

Identifies the amount of capacity that is allocated to the auto-tiered LUNs that reside on RAID 5 and RAID 10 storage tiers.

Displays two graphs: a graph that depicts the number of data migration calculations that the system performed and another graph that summarizes the capacities by Storage Class.

Update Graphs

Creates the following graphs that are based on the data from the selected auto‑tiered LUNs. Click Update Graphs to refresh the contents of the graphs.

Data Transferred By Number of Accesses: Indicates a histogram of the different regions of all the LUNs in the Storage Domain by the frequency of I⁠/O access.The histogram bar height represents the amount of data transferred. The y‑axis is not labeled.
Tier Structure By Storage Class and Priority: Indicates a graph of the Storage Class and the capacity of the LUN regions for the selected auto‑tiered LUNs. The chart also shows a number that represents the QoS priority for the auto‑tiered LUN. A table at the bottom of the chart provides the list of selected LUNs. The table is also a legend for the LUNs that are represented on the graph.
