Overview
StorView® Storage Management software is a full-featured, graphical,
HTML-based, software suite designed to configure, manage, and monitor
storage subsystems. StorView is built on a modular design and currently
supports only the RAID Module. However, other supported modules will
become available in the future.
The RAID Module provides the support for the Gateway E-842R RAID Storage
Solution with an extensive set of configuration and management tools.
StorView’s RAID Module is available in two versions: host-based and embedded.
The host-based version is installed on the host computer system. The
embedded version is installed on the RAID Controller.
StorView’s server component discovers storage solutions, manages and
distributes message logs, and communicates with other server components
installed on the same local network and external subnet networks. StorView has
an HTML-based interface that is accessed with a Web browser.
StorView incorporates Web server software (Apache 2.0) as part of the
installation, which provides the interface between the server component and
HTML interface. During installation, the Web server is automatically configured
and requires no further management. The installation of the Web server
software is self-contained and does not conflict with other Web server software
currently installed on your system.
Inter-server communication
Multicast
StorView’s server component uses multicasting technology to provide
inter-server communication with other servers when the Global Access license
is installed. During the server’s initial start-up, it performs a multicast
registration using the default multicast IP address of 225.0.0.225 on port 9191.
After registration is complete, the server can receive all packets sent to the
multicast address.
All packets sent to the multicast address remain in the local network, unless an
explicit server IP address outside the subnet is added in the “Inter-Server
Communication” Explicit StorView Server IPs > Preference Settings. For more
information, see “Monitoring settings” on page 35. The inter-server
communication abilities provide StorView with remote monitoring of other
installations of StorView and their monitored storage solutions.
StorView can communicate with any StorView installation on the local network.
These other StorView servers are displayed on the Main window and are listed
under the Other Servers section. They display the IP address, name, and overall
status of that server’s monitored storage solution. The server icon changes
states to indicate status. For more information, see “Server sidebar section” on
page 26.
Each server sends a check-in packet every 10 seconds. After an initial check-in
packet is received, all StorView servers know of the existence of the other
servers. If a server fails to send three check-in packets, the other servers mark
that server as missing. This is indicated by a white Server icon displayed on the
Main window under the Other Servers section.
