Configuring iSCSI on Your Storage Array

The following sections contains step-by-step instructions for configuring iSCSI on your storage array. However, before beginning, it is important to understand where each of these steps occur in relation to your host server/storage array environment.

Table 4-4 below shows each specific iSCSI configuration step and where it occurs.

Using iSNS

iSNS (Internet Storage Naming Service) Server, supported only on Windows iSCSI environments, eliminates the need to manually configure each individual storage array with a specific list of initiators and target IP addresses. Instead, iSNS automatically discovers, manages, and configures all iSCSI devices in your environment.

For more information on iSNS, including installation and configuration, see www.microsoft.com.
