Provisioning storage

  • Before you provision a Storage Volume, you must create a VSM.
  • The maximum supported size of the Storage Volume depends on the available capacity of VSM.
  • There is no limit to the number of Storage Volumes that you can create. But the composite capacity of the created Storage Volumes must be less than or equal to the capacity of the VSM they belong to. For example, if the total capacity of the VSM is 1 TB, then you can create a Storage Volume with the capacity of 1 TB or multiple storage volumes where the total capacity of all volumes is less than or equal to 1 TB.
  • You can enable both data compression and data deduplication on the same Storage Volume.
  • File system storage (NFS and CIFS) works together on the same Storage Volume, but block level storage (iSCSI or FC) does not.
  • You can back up Storage Volume by creating snapshots and then rolling back when required. For details, see Configuring local backup.

Note: By default, ElastiStor Storage Volume is thin provisioned. You can expand the Storage Volume up to the size of the Pool, provided the Pool has available storage.

Use the Storage Volumes page (ElastiCenter > Storage Volumes) to provision storage.

Field Description
Account Account for which you provision the storage.
Name Unique name for the storage.
Capacity Amount of disk space to be allocated.
Provision Mode Shared or Dedicated.
