CHAPTER 1
Before You Begin
The R/Evolution 2730 FC Controller Enclosure and SAS Expansion Enclosure are
high-performance storage solutions that combine outstanding performance with high
reliability, availability, flexibility, and manageability.
Supported configurations include a controller enclosure with or without attached
drive enclosures. A controller enclosure can contain two RAID controller modules
that interact and provide failover capability for the data path. The controller
enclosure can use SATA or SAS disk drive modules. Enclosures can be installed in
standard 19-inch EIA rack cabinets.
This chapter provides information that you must know before installing and initially
configuring your storage system:
■“System Management Software” on page 10
■“Hardware Components and LEDs” on page 11
■“Obtaining IP Values for Your Storage System” on page 21
■“Installation Checklist” on page 22

10 R/Evolution 2730 Getting Started Guide • January 2009
System Management Software
Embedded management software includes the RAIDar web-browser interface (WBI)
and the command-line interface (CLI) described below.
RAIDar
RAIDar is the primary interface for configuring and managing the system. A web
server resides in each controller module. RAIDar enables you to manage the system
from a web browser that is properly configured and that can access a controller
module through an Ethernet connection.
Information about using RAIDar is in its online help and in the Administrator’s
Guide.
Command-Line Interface
The embedded CLI enables you to configure and manage the system using
individual commands or command scripts through an out-of-band RS-232 or
Ethernet connection.
Information about using the CLI is in the CLI Reference Manual.
