RAID Technology - We use cutting-edge RAID Hardware to protect all data on the server against harddisk failures. This technology works by creating a mirror of all data on more than one harddisk automatically, without any delay i.e. all data is written to multiple harddisks simultanously so that if any harddisk fails, that harddisk will be marked as deactivated and the system will still continue to function as though nothing has happened by using the copy of the data on the other harddisk(s). The best part is that you do not require to make any changes or special code modifications in your website/web application for this technolgy to function.
RAID systems offer a significant advantage over non-RAID systems, both in terms of data protection and ability to maintain 100% uptime, as the system continues to function perfectly in case of disk failures. RAID technology also marginally improves the performance of the various services on the server.
As soon as a harddisk fails, notification alerts are sent out, so that the failed harddisk can be replaced by the system administrators. As such, the system continues to perform normally despite disk failures, using the mirror of the data on the additional harddisk(s).
