Aggregates window

You can use the Aggregates window to create, display, and manage information about aggregates.

Command buttons

Create
Opens the Create Aggregate dialog box, which enables you to create an aggregate.
Edit
Opens the Edit Aggregate dialog box, which enables you to change the name of an aggregate or the level of RAID protection that you want to provide for this aggregate.
Delete
Deletes the selected aggregate.
Note: This button is disabled for the root aggregate.
Actions
Provides the following options:
Change status to
Changes the status of the selected aggregate to one of the following status:
  • Online

    Read and write access to volumes contained in this aggregate is allowed.

  • Offline

    No read or write access is allowed.

  • Restrict

    Some operations—such as parity reconstruction—are allowed, but data access is not allowed.

Add Capacity
Enables you to add capacity (HDDs or SSDs) to existing aggregates.
Add Cache
Enables you to add cache disks (SSDs) to existing HDD aggregates or Flash Pool aggregates.

This button is not available for a cluster containing nodes with All Flash Optimized personality.

Mirror
Enables you to mirror the aggregates.
Volume Move
Enables you to move a FlexVol volume.
Attach External Capacity Tier
Enables you to attach an external capacity tier to the aggregate.
Refresh
Updates the information in the window.

Aggregate list

Displays the name and the space usage information for each aggregate.

Status
Displays the status of the aggregate.
Name
Displays the name of the aggregate.
Node
Displays the name of the node to which the disks of the aggregate are assigned.

This field is available only at the cluster level.

Type
Displays the type of aggregate.

This field is not displayed for a cluster containing nodes with All Flash Optimized personality.

Used (%)
Displays the percentage of space used in the aggregate.
Available Space
Displays the available space in the aggregate.
Used Space
Displays the amount of space that is used for data in the aggregate.
Total Space
Displays the total space of the aggregate.
FabricPool
Displays whether the selected aggregate is attached to an external capacity tier.
External Capacity Tier
If the selected aggregate is attached to an external capacity tier, displays the name of the external capacity tier.
Volume Count
Displays the number of volumes that are associated with the aggregate.
Disk Count
Displays the number of disks that are used to create the aggregate.
Flash Pool
Displays the total cache size of the Flash Pool aggregate. A value of NA indicates that the aggregate is not a Flash Pool aggregate.

This field is not displayed for a cluster containing nodes with All Flash Optimized personality.

Mirrored
Displays whether the aggregate is mirrored.
SnapLock Type
Displays the SnapLock type of the aggregate.

Details area

You can expand the aggregate to view information about the selected aggregate. You can click Show More Details to view detailed information about the selected aggregate.

Overview tab
Displays detailed information about the selected aggregate, and displays a pictorial representation of the space allocation of the aggregate, the space savings of the aggregate, which includes the total logical space used, total physical space used, overall savings from storage efficiency, data reduction ratio, FlexClone volume ratio, and Snapshot copies ratio, and the performance of the aggregate in IOPS and total data transfers.
Disk Information tab
Displays disk layout information, such as the name of the disk, disk type, physical size, usable size, disk position, disk status, plex name, plex status, RAID group, RAID type, and storage pool (if any) for the selected aggregate. The disk port that is associated with the disk primary path and the disk name with the disk secondary path for a multipath configuration are also displayed.
Volumes tab
Displays details about the total number of volumes on the aggregate, total aggregate space, and the space committed to the aggregate. The total committed space is the sum of the total size of all the volumes (online and offline) and the Snapshot reserve space of the online volumes.
Performance tab
Displays graphs that show the performance metrics of the aggregates, including total transfers, IOPS, and write workload impact. Performance metrics data for read, write, and total transfers is displayed, and the data for SSDs and HDDs is recorded separately. Performance metrics data for the impact of write workload to "nvlog" and dirty buffer is also displayed.

Changing the client time zone or the cluster time zone impacts the performance metrics graphs. You must refresh your browser to see the updated graphs.
