Handling excess bandwidth in a storage system

A non-transitory computer readable medium for managing write buffers, the non-transitory computer readable medium stores instructions executable by a processor for:

• receiving write requests for writing input information units to the storage system;
• estimating, by a monitoring unit of a storage system, an occurrence of a future overflow of first write buffers that are allocated, during steady state operation, to store input information units before the input information units are processed and migrated to a permanent storage;
• responding to the estimating, wherein the responding comprises:
• (i) storing at least some of the input information units at second write buffers without temporarily storing the at least some of the input information units in the first write buffers;
• wherein the first write buffers exhibit a higher storage speed than the second write buffers, wherein an aggregate storage capacity of the first write buffers is a fraction of an aggregate storage capacity of the second write buffers;
• (ii) reducing a rate of a migration of input information units from the first write buffers and the second write buffers to the permanent storage;
• and
• (iii) introducing intentional delays in handling an ingestion of one or more newly received write requests;
• and
• if determining that the responding prevented the occurrence of the future overflow of first write buffers, then the determining is followed by writing input information units only to the first write buffers.
