1.1. Introducing Named Objects
DX Storage version 5.0 supports the option of storing and accessing objects in a DX Storage public
or private cloud by name or by UUID as shown in the following figure.
The figure shows two objects, one named and one unnamed, in a cluster named cloud.com. The
named object is stored in a bucket named photos while the unnamed object is identified by its
UUID and is stored in a particular domain in the cluster. The terms bucket and domain are defined in
Section 1.3, "Common Named Object
You access the named object using the URL
http://cloud.com/photos/photo1.jpg
You access the unnamed object using the URL
http://cloud.com/2570D424FF81DE175058B17652F3CDC8
Your DX Storage 5.0 and later private or public cloud can have:
• All unnamed objects
• All named objects
