Abstract
Systems and methods for determining when to allow a temporary compromise on redundancy in a storage system. When servicing write requests, the storage system may utilize data redundancy techniques when writing data to backend storage devices. The operating conditions of the storage system are tracked and early acknowledgements for write requests may be permitted when the storage system is healthy enough. If the number of unacknowledged writes is greater than a programmable threshold, then early acknowledges may be prohibited. Also, if the number of ongoing rebuild processes is greater than a programmable threshold, then early acknowledges may be prohibited.
