About this guide
This guide provides information about using the Storage Management Utility (SMU) to configure and
manage storage associated with an array controller that supports iSCSI networking.
Intended audience
This guide is intended for network administrators and storage managers with moderate or advanced
knowledgeofIPandstoragenetworks.
Prerequisites
•Determine who will install and configure your system.
A moderate level of knowledge about storage systems, Storage Area Networks (SANs), and
IP networks is required to install and manage this storage system.
If you are not familiar with installing and configuring storage systems or IP
networks, HP can install and configure your system. For more information, see
“HP installation and configuration assistance” on page 11.
