Doesn't everybody do active/active? Not everybody starts there
Yes, active/active is supported by Zerto, VMware, BlueLock, Sungard, Veeam, HAProxy, F5 Networks and Stack Overflow, among others, all of whom have advanced disaster recovery to an advanced stage. But ScaleArc wishes to purge disaster recovery as a concept for database servers and set up systems so that the only possibility is one active system fails over to another instantly ready to go. There's no identifiable disaster and there's no recovery period. Not everybody starts out there.
