Article Summary

CTERA Portal can write your data to storage nodes from many different vendors. The Storage Nodes page in the Global Administration view enables you to easily add new storage nodes, dedicate storage nodes to virtual portals, stop and start writing to different storage nodes, and migrate data seamlessly from a storage node to other storage nodes.

What Storage Node to Use

Storage considerations include company policy, cost, and total size required.

CTERA provides a storage node with the installation, Local Filesystem, which can be used up to a maximum of 20TB. 

NFS storage, EMC Isilon (NFS), Generic (NFS), and NetApp (NFS), storage nodes can be used for storage up to 100TB.

All other storage nodes support unlimited storage, such as Amazon S3 and IBM Cloud Object Storage (S3).

Viewing Storage Nodes

To view all storage nodes in the system:

  • In the global administration view, select Main > Storage Nodes in the navigation pane.
    The STORAGE NODES page is displayed.
    The following information is displayed for each storage node:
    NAME – The storage node's name.

Status (under the name) – Whether the storage node is read/write enabled or read and delete only.

TYPE – The storage node's type.
BUCKET – The name of the storage node's bucket.
DEDICATED TO – The name of a single virtual portal to which the storage node is dedicated, if applicable.
STATUS – The storage node's current status. This can be either of the following:

  • Connected
  • Not Connected
    The portal does not attempt to store new blocks in storage nodes that are not connected.

STORAGE USAGE – The amount of storage available, followed by the amount of used storage. This field is only relevant for the Local Filesystem storage node, which is the default storage node when setting up the CTERA Portal.

To view details of a specific node:

  • Click the node name on the STORAGE NODES page.
    The storage node window is displayed with the storage node name as the window title.
    The details displayed depend on the type of storage node.
