Workload skew curve report
The workload skew curve report provides a summary of workload distribution across tiers within a pool.
Each line of the report represents 100 GB capacity on one tier of a pool. The report is sorted according to IOPS, with the hottest data, which is handling most IOPS, listed first.
- Index
- Index value for the row.
- DSS
- The storage system ID.
- Datetime
- Time stamp when the data was collected.
- Extpool
- The extent pool ID.
- Tier
- The storage tier type:
- 0
- Hot data tier, which contain the most active data. This tier can also serve as the home tier for new data allocations.
- 1
- Mid-data tier, which can be combined with one or both of the other tiers and will contain data not moved to either of these tiers. This is by default the home tier for new data allocations.
- 2
- Cold data tier, which contains the least active data.
- Extent_cap(MB)
- The extent capacity in MB.
