This Knowledgebase article provides information about Neverfail's ability to operate on varied hardware.
Our product can run across different hardware as long as a pair’s multi-processor capability matches. This means a multi-processor capable server must be paired with another multi-processor capable server. The actual number of processor doesn’t have to match. Machines can be different models, have different manufacturers, motherboards and processor brands. Storage can be any mix of configurations and architectures, as long as the Secondary server has as much storage as the Primary.
