DAS management software is the Navisphere application.
The communication bridge between the Navisphere application and the DPE array is the
Navisphere agent. The Navisphere agent resides on every DPE array’s node and
communicates directly with the storage system firmware. It requires a graphical interface for
setting up configuration parameters.
In an EPC configuration with a PowerConsole, the Navisphere application is integrated in
the ClusterAssistant launch board.
Cabling: up to 30m is supported with copper using twinax cable assemblies. Medium to long
distances of 10m to 10km is supported using the appropriate Media Interface Adapters
(MIA) that converts the electrical signal to fibre-optics.
Connection of nodes to DAS drawers is direct or made via Fibre Channel hubs. The length
of the copper cables used is 3m by default. A 10m cable is used to connect components in
distinct racks.
