Overview of physical configurations
When you order your DS8000 models, you can use the DS8000 feature codes to
customize the physical configuration of your model.
You must follow established configuration rules to create a valid
configuration—not just for the model itself, but also for the storage unit of which
the model is a part. A storage unit can consist of a stand-alone base model or it
can contain the base model plus expansion models.
Table 11 provides the storage unit configuration ranges for the DS8700 and DS8800.
