Storage systems

Attention:
A four-digit feature code is used to specify a component that is configurable in the IBM configurators, the eBusiness Configurator (eConfig) and the IBM Web-based Hardware Configurator, used in US and Canada. Options that do not have feature codes cannot be integrated by IBM into a system using these IBM configurators. To purchase options separately, refer to the option part number provided in this document.
