MDCU provides a consolidated approach to configure the iSCSI network of
host servers and iSCSI-based Modular Disk storage arrays (PowerVault
MD32xxi) using a wizard-driven interface. This utility also enables you to
configure the iSCSI sessions of the host server according to the best practices
and to achieve load-balanced paths with the storage array iSCSI host ports.
NOTE: The configuration tasks performed by this utility can also be performed
manually. To perform a manual configuration, see Appendix A—Manual
Configuration of the
Dell PowerVault MD3200i and MD3220i Storage Arrays
Deployment Guide .
