## 14.8.2 DS8900F embedded AOS 

AOS is an embedded feature, on DS8700, DS8800, DS8870, DS8880, and DS8900. The AOS software package is pre-installed and customized on the Management Console. This technique eliminates the need to provide an additional system to operate an AOS Gateway. Embedded AOS is a secure, fast, broadband form of remote access. You can choose to allow unattended or attended remote access sessions. If you select attended remote access sessions, IBM Support contacts you or the storage operator to start the support session through DS CLI or the DS GUI. 

The IBM SSR configures AOS during the installation or a later point in time by entering information that is provided in the inbound remote support worksheet. The worksheets can be found in the Installation and Planning Guide, or online in the Planning Section of the IBM DS8900 Knowledge Center at: 

https://www.ibm.com/support/knowledgecenter/SSHGBU_9.0.0/com.ibm.storage.ssic.help .doc/f2c_icplanningovrw_37tadj.html 

In addition, your firewall needs to allow outbound traffic from the HMC to the AOS Infrastructure. The inbound remote support worksheet provides information about the required firewall changes.
