A simple AOS connection to the DS8880 is shown in Figure 15-9. For more information about  AOS  prerequisites  and installation  see  IBM Assist On-site for Storage Overview    REDP-4889. AOS is an embedded feature  on DS8700  DS8800  DS8870  and DS8880. The AOS  software package is preinstalled 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  DS8880 Knowledge Center at: 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.  http://www.ibm.com/support/knowledgecenter/ST5GLJ_8.2.0/com.ibm.storage.ssic.help. doc/f2c_custmztnwkshts_1xznxr.html For more information about AOS  see  IBM Assist On-site for Storage Overview   REDP-4889. 482  IBM DS8880 Architecture and Implementation Figure 15-9 DS8880 AOS connection 15.6.2 DS8880 embedded AOS
