Article Summary

Thumbnails are reduced-size versions of pictures or videos, used to help in recognizing and organizing them, serving the same role for images as a normal text index does for words.

CTERA Thumbnail Service Requirements and Limitations

For test environments that use a single server, this server can be used for the Thumbnail service. For production environments that use more than one server, the servers for the Thumbnail service cannot be the main, primary, database server nor a preview server. CTERA Portal can include more than one application server defined as a thumbnail server.

To access the portal cloud drive directly to view the thumbnails, the user must have a subscription plan that includes the Cloud Drive Connect or Cloud Drive Full service. To collaborate on content, the user must have a subscription plan that includes the Cloud Drive Full service

The Thumbnail service requires separate storage for the thumbnails. This storage is configured as part of the service set up. In addition to the storage node that is used for the thumbnails, the standard storage node that is used for the CTERA Portal must also be an S3 type storage node with Direct Mode enabled.

Note

If the CTERA Portal uses a non-S3 type storage node, then a new S3-type storage node must be configured and dedicated to the portal that will display thumbnails.

The CTERA Portal must have a trusted certificate that is not self-signed, for example, from GoDaddy, and not the self-signed certificate, provided with the CTERA Portal installation.

When configured to display thumbnails, the following file types are displayed as thumbnails: JPEG/JPG, PNG, GIF, BMP, TIFF, WebP, SVG. Only files less than 50MB can be displayed as thumbnails. The default maximum size for files is 20MB.

Thumbnails are displayed in the portal and not in Windows, macOS, nor a CTERA Edge Filer.
