Paths for Vantage Storage Overview

Vantage stores are named locations for temporary files. They are used in Vantage to
conveniently store and access working media and attachment files, and to write media
and other output files. Many Vantage services require access to files; Windows clients
such as Workflow Portal also read and write files. These programs (both Windows
programs and services) may run on one computer. Usually, however, they are
distributed on many computers in an array. In an array, file access must be managed to
ensure that the all programs can function correctly.
Vantage stores can be specified on Windows computer using the following forms:
•
UNC paths (shares): \\ComputerName\Sharename
•
Drive-letters: C:\folder\folder
If Vantage is installed on a single server—the Vantage database, Vantage services,
clients, Vantage stores and folders (an All-in-one domain), you can use either form.
However, Telestream recommends that you always use the UNC path form to reduce
file access problems. It is a requirement when you are operating in an array.
Drive-letter paths are defined in the context of a local computer; it does not identify the
computer that hosts the drive. This prevents them from being useful in arrays. For
example, if you specify a Vantage store on drive C using a drive letter, and a Workflow
Portal operator on a different computer tries to view files in that store, Workflow Portal
searches for files on drive C on the operator's computer, not the Vantage server.
In another example, you create a workflow in Workflow Designer installed on Computer
A. It has a Watch action, which is executed by a Vantage Monitor Service running on
Computer B. You specify a hot folder on drive C on Computer A, where Workflow
Designer is installed. When the service executes the Watch action, it attempts to locate
the hot folder on Computer B's C drive, which does not exist.
When any Vantage service or client program needs to access and use Vantage storage
or a directory on a different computer, you must specify the path using the UNC form.
When services or clients access Vantage storage from another computer, the Vantage
storage location or directory must be configured as a share, and access must be
granted to the appropriate Windows users. For more information, see Windows
Authentication Guidelines in the Vantage Domain Management Guide.
When you plan to use a SAN system, be aware that some SAN systems expose the
shared drive as a letter (mapped) drive—for example, X:—that is visible in any SAN. You
can utilize SAN drives via a letter drive reference, provided that each Vantage server is a
SAN client and that all mount points use the same letter.
