RAIS Fault Tolerance Explained
Like RAID, RAIS provides data-level fault tolerance by operating in a mode that is analogous to RAID Level 1. This brings unprecedented data-level fault tolerance to cluster computing, not only assuring that transaction data is secure through hardware failure, but that your application service level requirements can be met or exceeded with RAIS.
RAIS level 1: Mirroring
Mirroring refers to complete redundancy of executing code and memory on 2 or more servers. The code that executes on one Logical Array is completely duplicated on a similar array hereby providing 100% code fault tolerance. This literally means that your applications will stay up and running through any individual system failure.
