The maximum provisioned space is the metadata drive capacity in a cluster. Before Netapp Element software 6, the total size of a volume was reserved as provisioned space. This type of space provisioning limited the number of new volumes, snapshots, and clones that could be created in a cluster because the metadata became fixed. The metadata was reduced from fixed space to thin-provisioned space in Netapp Element software 6, which enables the potential to provision about 16 times the amount of space because the metadata size is no longer fixed. The provisioned space now takes into account whether or not data has been written to a volume. If data has not been written to a volume, then no space is provisioned.
To calculate the provisioned space for a node, you need the usable metadata capacity per drive in bytes for your NetApp SolidFire node. The amount of used and provisioned metadata space can be viewed in the Reporting > Overview > Cluster Capacity window of the NetApp Element software web UI.
The following table provides information to help determine the usable metadata capacity for a node:
|Model||Drive size (GB)||Metadata drives||Block drives||Raw metadata capacity (GB)||Raw block capacity (GB)||Usable metadata capacity (GB)||MaxProvisionedSpace (bytes)|
