Abstract: The disclosure herein describes enhancing data durability of a base component using multiple delta components. A first and second delta component are generated based on the base component becoming unavailable. A write operation targeted for the base component is routed to the first delta component and to the second delta component. Based on routing the write operation targeted for the base component to the first delta component and to the second delta component, a bit associated with a data block affected by the write operation is changed in each of the tracking bitmaps of the first and second delta components. Based on detecting the base component becoming available, one delta component of the first and second delta components is selected, and the data block affected by the routed write operation is synchronized from the selected delta component to the base component. Later, the first and second delta components are removed.

Abstract: Computer system and method for managing storage requests in a distributed storage system uses congestion data related to processing of storage requests for local storage to adaptively adjust a bandwidth limit for a first class of storage requests to be processed. The bandwidth limit is enforced on the storage requests belonging to the first class of storage requests without enforcing any bandwidth limit on the storage requests belonging to a second class of storage requests.
