The EnergyChaser system is designed to log the most recently retrieved energy values to the local hardware where it is initially accumulated for transport to the server.
If a loss of network connection occurs, there is no data loss. When the network connection is restored, the data is automatically uploaded to the EnergyChaser server. The EnergyChaser server also continuously monitors the connection to the remote data collector. If connectivity is lost to the remote data collector, an alert e-mail is sent to the responsible party to take corrective action.
If you purchase EnergyChaser as a service, you can stop reading now because we take care of the server hardware and backup for you. If you decide to purchase the EnergyChaser system outright, please read further.
Even with today's reliable computer hardware, hard drives occasionally stop functioning (‘crash’) - when this occurs it often results not only in system failure, but in a complete loss of historical data. In order to secure this critical data, each EnergyChaser system comes with two hard drive systems. One is the main drive system that consists of two physical hard drives that act as one unit in a standard configuration used by almost all computer servers today (known as ‘RAID1 configuration’). The advantage is that one of the drives can fail and the system will remain operational until the failed unit is repaired.
The other remaining drive is a backup drive. As the system operates, the data is automatically and frequently backed up to the backup drive. If the first drive system was to fail, your data is safe on the backup drive. This combined system offers double redundancy. The first level of redundancy occurs when one of the main drives fails. In this case, the system will continue to operate with no loss of data or any effect on operations. The second level of redundancy is if the main drive system fails completely, your data will still be safe on the backup drive with little loss of data. Data will continue to be collected by the remote collection units or software until the EnergyChaser server is operational again.
Because the EnergyChaser system uses standard computer server hardware, there are many options available to improve the system reliability with redundant power supplies and RAID 5 hard drive configurations. Talk to your IT people, they will know these terms well. These actions working together ensure a constant, high quality data stream to fill the EnergyChaser database. This solid data generates reports and bills you can count on and trust well into the future.
