RAID User Guide
2 Introduction
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 the RAID Module. However, other modules will become available in
the future.
The RAID Module provides the support for the SR1202 Enclosure Platform (SR1202 M1 RAID Storage
Solution) with an extensive set of configuration and management options. StorView’s RAID Module is
available in two versions: host-based and embedded. The host-based version is installed on the host
computer system, while the embedded version is rooted on the SR1202 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 front end, accessed with a web browser, and provides
the interface to the end user.
StorView incorporates web server software as part of the installation, Apache 2.0, 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 will 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. Once registration is complete, the server is able to 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, see ”Monitoring Setting” beginning on page 33. The inter-server
communication abilities provide StorView with remote monitoring of other installations of StorView
and their monitored storage solutions.
StorView has the ability to communicate with any StorView installation on the local network. These
other StorView servers are displayed on the Main screen and are listed under the “Other Servers”
section. They display the IP address, name, and a overall status of that server’s monitored storage
solution. They indicate the status of a monitored server storage solution, by the server icon changing
to one of a few different states, see ”Server Sidebar Section” beginning on page 21.
Each server sends a “check-in” packet in 10 second intervals. Once an initial check-in packet is
received, all StorView servers will know the existence of the other servers. If a server fails to send
three check-in packets, the other servers will mark that server as “missing”. This is indicated by a
white “Server” icon displayed on the Main screen under the “Other Servers” section.
When the server service that “owns” the monitored storage solution is down for any reason and
three check-in packets are not received, the monitoring will automatically be transferred to another
StorView server.
