6.3.3Model upgrades

The DS8000 series models are modular systems that are designed to be built upon and upgraded from one model to another in the field, helping clients respond swiftly to changing business requirements.

IBM service representatives can upgrade a Model 921 in the field when you order a model conversion to a Model 922 or Model 9A2. You can also change the storage system LPAR configuration, both from non-LPAR to LPAR, from LPAR to non-LPAR (According to the announcement letter, model upgrades will be offered after GA).

Figure 6-8summarizes the model conversions planned for the DS8000 series.
