Management console network requirements
You must plan for the network requirements of the management console.
Each management console requires a dedicated connection to the network.
Note: If you plan on accessing the DS CLI or DS8000 Storage Management GUI
and have a firewall between the management console and your network, open the
following TCP/IP ports before installation: 1750, 1751, 1755 for CLI, and 8452 for
the DS8000 Storage Management GUI.
Remote support connection requirements
IBM highly recommends remote-support connections so that the storage system
can report failures and transmit pertinent debugging data to IBM.
When call home is used, your technical support representative can quickly isolate
and resolve potential issues with the storage system. The strategic and preferred
remote support connectivity method for call home is internet SSL (Secure Socket
Layer) for management-console-to-IBM communication.
For IBM remote access to the management console and the storage system, the
preferred remote support connectivity method is Assist On-site (AOS). AOS
provides a network-type connection that is secured by SSL and state-of-the-art
encryption technology. If your security guidelines allow, AOS can be turned on and
configured on the management console, which is the preferred implementation.
Alternatively, AOS is installed on a PC that you provide and maintain. Contact
your technical support representative for more details.
In addition to AOS, IBM also offers remote support center (RSC). It is a simple
SSH proxy based remote service solution that can be used if AOS does not meet
your security guidelines. Contact your technical service representative for more
information on RSC.
Remote support must be ready at the time of the initial installation of the DS8000.
For internet-based remote support, you must open your firewalls.
Remote power control requirements
Use the remote power control settings to control the power of your storage
complex. Settings can be controlled through the DS8000 Storage Management GUI
running on the management console.
There are several settings for remote power control.
Host attachment communication requirements
Use host attachment communication requirements information to connect the host
attachments in your network.

adapters that are installed in your host system.
Channel architecture provides various communication protocols. Each
interconnected storage system within the architecture is referred to as a node,
and each host is also a node. Each node corresponds to one or more ports. (In
