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.
v You must use worldwide port names to uniquely identify Fibre Channel
adapters that are installed in your host system.
v For open-system hosts with Fibre Channel adapters, keep in mind that Fibre
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
the case of Fibre Channel I/O adapters, these ports are Fibre Channel ports.)
Each port attaches to a serial-transmission medium that provides duplex
communication with the node at the other end of the medium. You can
configure your network structure that is based on one of three basic
interconnection topologies (network structures):
– Point-to-point and switched fabric
– Fibre Channel arbitrated loop
– Fibre Channel (FICON). This connection does not apply to open systems.
See the IBM DS8000 Host Systems Attachment Guide for more information about
these supported topologies.
v The maximum distance between a shortwave host adapter Fibre Channel port
and the following network components is 100 meters (328 ft 1 in.) at 16 Gbps.
For a longwave host adapter Fibre Channel port, the maximum distance is 10
km (6.2 miles).
– Fabric switches
– Fabric hubs
– Link extenders
– Storage system Fibre Channel port
The maximum distance might be greater than 10 km (6.2 miles) when a link
extender provides target initiator functions or controller emulation functions.
Note: Do not use link extenders with emulation functions on links over which
Remote Mirror and Copy operations are performed. Link extenders with
emulation functions introduce more path delay.
v Because the Fibre Channel architecture allows any channel initiator to access any
Fibre Channel device, without access restrictions, a security exposure can occur.
