All StorCase
Technology SCSI removable enclosures adhere strictly to SCSI specifica-
tions. These products are typically installed into storage system configurations which con-
tain a variety of components (such as cables, terminators, and connectors), which may
have varying SCSI characteristics when used together in some configurations.
To minimize these unpredictable effects caused by varying system specifications, StorCase
recommends the Data Express Repeater Board on all Ultra160 Data Express receiving
frames. The StorCase Data Express
Repeater Board has been shown to resolve issues
associated with combining system components designed for different SCSI technologies
(single-ended or LVD) and/or by different manufacturers. For more information and data,
please refer to the Repeater Board Benefits and Downward Compatibility technical papers
