UnifiedAUTH is Qsan's latest patent filing mechanism that integrates and supports directory services such as Microsoft Active Directory and LDAP. Similar to single sign-on experience, UnifiedAUTH provides consistent account management across different data services. Users don't need to memorize different accounts and passwords for different data services. Once the directory service is selected and enabled, the same account/password from the selected directory service can be applied to all data service access across different OS clients.

U400Q uses QCentral as management tool. It's a Java-based, centralized management interface, which allows you to manage multiple Qsan storage systems through the same user interface at the same time. Graphic intuitive design helps users get used to the administration tasks more quickly.
