Netapp how many luns per volume

The maximum number of nodes in the cluster is unaffected by the presence of Infinite Volumes. Aggregates Maximum per node In an HA configuration , this limit applies to each node individually, so the overall limit for the pair is doubled. Volumes Maximum per cluster for NAS 12, 12, Infinite Volumes do not count against this limit, but their constituent volumes do. This limit might be lower for FlexVol volumes that use deduplication.

All rights reserved. Part No. Array LUNs Minimum size for root volume. See the Hardware Universe. Files Maximum size. Files Maximum per volume. Volume size dependent, up to 2 billion. FlexCache volumes Maximum per system. FlexClone volumes Hierarchical clone depth. The maximum depth of a nested hierarchy of FlexClone volumes that can be created from a single FlexVol volume.

FlexVol volumes Maximum per system. FlexVol volumes Minimum size. FlexVol volumes bit Maximum size. FlexVol root volumes Minimum size. LUNs Maximum per volume. LUNs Maximum size. The 64 GB minimum upper limit is based on 1 MB cylinder size and the maximum cylinder count of the upper limit of a 16 bit value.

This means that regardless of how small the LUN starts out as, you can always expand it to at least 64 GB. It is only available in elevated privilege modes advanced and diag:. Note: The last line of this output max resize size will denote how large a LUN might be ultimately grown to. Volume Autosize is useful if the volume's containing aggregate has enough space to support a larger volume. Volume Autosize allows you to use the free space in the containing aggregate as a pool of available space shared between all the volumes on the aggregate.

Volumes can be configured to automatically grow as needed, as long as the aggregate has free space. When using the Volume Autosize method, you can increase the volume size incrementally and set a maximum size for the volume.

Monitor the space usage of both the aggregate and the volumes within that aggregate to ensure volumes are not competing for available space. Note : The autosize capability is disabled by default. Run the vol autosize command to enable, configure and to view the current autosize settings for a volume. Snapshot Autodelete is a volume-level option that allows you to define a policy for automatically deleting snapshot copies, based on a definable threshold.

You can set the threshold, or trigger, to automatically delete snapshot copies when:. When SIS is enabled on the volume, fractional reserve behaves as if a snapshot is always present.
