Low latency data mirroring in a large scale storage system

A method for low-latency data mirroring in a storage system, the method may include receiving, by a compute node of the storage system, a read request for reading a data unit stored at a primary storage block of the storage system; determining, by the compute node and based on primary storage block...

More Information
Summary:A method for low-latency data mirroring in a storage system, the method may include receiving, by a compute node of the storage system, a read request for reading a data unit stored at a primary storage block of the storage system; determining, by the compute node and based on primary storage block metadata, whether a content of the primary storage block is consistent; and responding to the determining of whether the content of the primary storage block is consistent. The responding may include (a) when determining that the primary storage block is inconsistent-copying the data unit from the primary storage block to a secondary storage block of the storage system, and updating the primary storage block metadata; and (b) reading the data unit from the primary storage block and sending the data unit to a requesting entity.
