About this document
This document provides instructions for installing and customizing the configuration
of your IBM TotalStorage DS4100 storage server. It also provides hardware
maintenance procedures and troubleshooting information.
FAStT product renaming
IBM is in the process of renaming some FAStT family products. Table 1identifies
each new DS4000 product name with its corresponding FAStT product name. Note
that this change of product name only indicates no change in functionality or
warranty. All products listed below with new names are functionally-equivalent and
fully-interoperable. Each DS4000 product retains full IBM service as outlined in
service contracts issued for analogous FAStT products.
