What is the SRB logical name space?
It is easy to think of SRB Collections as Unix directories (or Windows folders), but there is a fundamental difference. Each individual data object (file) in a collection can be stored on a different physical device. Unix directories and Windows folders use space from the physical device on which they reside, but SRB collections are part of a “logical name space” that exists in the MCAT and maps individual data objects (files) to physical files. The logical name space is the set of names of collections (directories) and data objects (files) maintained by the SRB. Users see and interact with the logical name space, and the physical location is handled by the SRB system and administrators. The SRB system adds this logical name space on top of the physcial name space, and derives much of its power and functionality from that.
