Understanding RAID array notifications
The RAID controller is able to notify you and others of RAID events by sending email and SNMP traps. This means you do not need to routinely inspect the RAID logs; you can just receive notifications if something changes or goes wrong.
Using email, events happening with the RAID can be relayed from the RAID controller to people in real time. This enables early detection of RAID and drive failures so you and your team can quickly take action. Because all GigaStor and Apex hardware appliances use RAID 5, which allows the RAID to operate with one failed drive, being immediately notified of a failing drive might provide enough time to replace the drive and avoid “breaking” the RAID array. A broken RAID array cannot store incoming network traffic or create new network trending data.
Email notifications about the RAID, from the RAID, can be part of a strategy for ensuring your hardware appliance is performing well. Many GigaStor and Apex appliances are installed in a server room or data center, and this makes monitoring the status of the system something that is best done remotely. If you configure RAID email notifications and the sent email describes no issues,then the RAID array is functioning properly and is able to read and write data. This can reduce the amount of time needed for troubleshooting data collection issues.
RAID email notifications are handled by the RAID controller—a vital part of your RAID card. The RAID controller has its own program with the ability to generate diagnostic log messages. Some log messages are informational like the RAID has been turned on, but some log messages are more critical like a hard drive encountering bad sectors. All of these log messages are available to view inside the RAID controller interface. Setting up RAID email notifications sends these same log messages to email addresses of your choosing (up to four addresses). You are given full control of the recipients and type of log messages the RAID controller sends as email notifications.
