Common Array Manager: Simple Guide for Storage Array Management
Common Array Manager, often called CAM, is a software tool used to manage storage arrays. It is mainly used with Sun and Oracle storage systems. CAM helps administrators control, monitor, and configure storage hardware from one central place.
In many IT environments, storage systems are large and complex. Managing each storage array separately can take a lot of time and increase the risk of mistakes. Common Array Manager solves this problem by giving administrators one interface to manage multiple arrays.
This article explains Common Array Manager in simple terms. It covers what it is, how it works, its main features, installation steps, best practices, common problems, and when it should be used Book
What Common Array Manager Is
Common Array Manager is storage management software. It does not store data itself. Instead, it helps manage storage hardware.
Main purpose of Common Array Manager
Common Array Manager is used to:
-
Manage multiple storage arrays from one place
-
Monitor hardware health and system status
-
Create and manage storage volumes
-
Connect storage volumes to servers
-
Send alerts when problems occur
What Common Array Manager is not
It is important to understand what CAM does not do.
Common Array Manager:
-
Is not a storage device
-
Is not a backup tool
-
Is not an operating system
It works as a management layer between administrators and storage hardware.
Supported Systems and Basic Requirements
Before installing Common Array Manager, you must check if your systems are supported.
Supported storage arrays
Common Array Manager works with selected Sun and Oracle storage arrays.
Typical supported systems include:
-
Sun StorageTek arrays
-
Oracle storage systems
Support depends on the CAM version, so compatibility should always be confirmed.
Supported operating systems
Common Array Manager runs on a separate management server, not on the storage array.
Commonly supported operating systems include:
-
Solaris
-
Linux (specific versions)
-
Some versions support Windows
Hardware and network needs
To run CAM properly, you need:
-
A dedicated management server
-
Reliable network access to storage arrays
-
Correct IP and DNS settings
-
Firewall rules that allow required ports
The management server does not need high performance hardware, but it must be stable.
Security basics
CAM includes basic security features such as:
-
Secure web access using HTTPS
-
User login with passwords
-
Role-based permissions
Security should be configured during setup.
How Common Array Manager Works
Common Array Manager acts as a central controller between administrators and storage arrays.
Web-based management interface
Most administrators use CAM through a web browser.
With the browser interface, you can:
-
View storage health
-
Check alerts and warnings
-
Create and manage storage volumes
-
Perform daily administration tasks
The interface is visual and easy to understand.
Command Line Interface
Common Array Manager also provides a Command Line Interface, called CLI.
The CLI is useful for:
-
Automation
-
Running scripts
-
Performing repetitive tasks
-
Managing systems without a browser
Both the browser and CLI offer similar core features.
Array discovery process
Before managing a storage array, CAM must discover it.
Discovery usually includes:
-
Entering the array IP address or hostname
-
Providing administrator credentials
-
Verifying network communication
After discovery, the array appears in the CAM dashboard.
Installation and Setup Process
Installing Common Array Manager requires planning and preparation.
Downloading Common Array Manager
CAM software is downloaded from official Oracle support sources.
Important points:
-
Select the correct version
-
Download required patches
-
Avoid unofficial websites
Installation steps overview
Typical installation steps include:
-
Run the installer on the management server
-
Select the installation location
-
Configure basic services
-
Complete the setup process
The installer sets up:
-
Web services
-
Background processes
-
Default configuration files
First login steps
After installation, CAM is accessed through a browser.
Basic steps:
-
Open a web browser
-
Enter the CAM URL (HTTPS with a specific port)
-
Log in using administrator credentials
The first login may ask for initial setup confirmation.
Adding storage arrays
Once logged in, you can add storage arrays.
Steps include:
-
Open the discovery option
-
Enter array connection details
-
Confirm successful discovery
Main Features of Common Array Manager
Common Array Manager offers several important features for storage management.
Dashboard and health monitoring
The dashboard provides a summary view of the environment.
It usually shows:
-
Storage array status
-
Disk health
-
Alerts and warnings
-
System notifications
Monitoring helps detect issues early.
Alerts and notifications
CAM can send alerts when problems occur.
Common alert types include:
-
Disk failures
-
Hardware warnings
-
System errors
Alerts can be delivered through:
-
On-screen messages
-
Email notifications
Storage provisioning
Storage provisioning is one of CAM’s most important functions.
Creating volumes and virtual disks
Administrators can:
-
Create virtual disks
-
Choose size and RAID level
-
Control access permissions
This allows efficient use of available storage.
RAID overview
CAM supports different RAID levels depending on hardware.
RAID helps with:
-
Data protection
-
Performance
-
Storage efficiency
Choosing the right RAID level is important for safety.
Mapping storage to hosts
After creating volumes, they must be connected to servers.
Mapping involves:
-
Using host identifiers (HBA or WWN)
-
Assigning access rights
-
Verifying server visibility
User and access management
Common Array Manager supports role-based access.
Typical roles include:
-
Administrator
-
Operator
-
Read-only user
Limiting access reduces risk.
Reports and performance views
Some CAM versions provide reports such as:
-
Storage capacity usage
-
Performance trends
-
Historical health data
Reports help with planning and troubleshooting.
Administration and Maintenance Tasks
Regular maintenance is important for stable storage systems.
Daily monitoring checklist
Administrators should regularly:
-
Review dashboard alerts
-
