Disk Space Requirements - Novell GROUPWISE 8 - LIBRARIES AND DOCUMENTS Manual

Disk Space Requirements

You need to know the disk space requirements for your libraries in order to choose appropriate
locations for document storage areas.
If you have chosen a centralized library configuration, your document storage areas are all serviced
by the POA of the DMS post office. Therefore, you can calculate the disk space requirements for
your GroupWise system as a whole. If you have chosen a decentralized configuration, document
storage areas are located throughout your GroupWise system. Therefore, disk space requirements
must be calculated separately for each library.
If your current document storage statistics are an accurate indicator for a given library or for your
system, use them for calculating your disk space requirements. Otherwise, use the following formula
for determining DMS storage needs:
Formula:
Number of Users
x Average Number of Documents per User
x Average Document Size
x Average Number of Versions per Document
-------------------------------------------
Disk Space Required for Library
Example:
250 Users
x 200 Documents per User
x 50 KB per Document
x 10 Versions per Document
-----------------------
25 GB of Disk Space
Users might create a new version of a document any time they revise it. Because all versions of a
document are saved in BLOB storage with the original document, disk space can be used up
quickly! If you know how many versions per document your users average, use that value in the
formula; otherwise, allow for an average of at least ten versions per document.
If your Average Document Size value for the formula is based on non-GroupWise documents, they
will be compressed by about 50% after they have been imported into GroupWise and stored in
BLOBs.
You should research your current or expected document usage before deciding where to store
documents.

If your values are calculated for the system (rather than per library), enter this information on only one of
the worksheets.
Direct Access Paths to Document Storage Areas
To define a document storage area, you need to know its direct access path. For example, a UNC
path specifies the absolute location of the document storage directory.
