Minimizing read latency for solid state drives
A processing device of a storage server receives a write request to write to a first logical address of a virtual storage device that is mapped to a plurality of SSDs. The processing device stores a data block associated with the request in a buffer, stores an entry for the write request in a queue,...

| description | A processing device of a storage server receives a write request to write to a first logical address of a virtual storage device that is mapped to a plurality of SSDs. The processing device stores a data block associated with the request in a buffer, stores an entry for the write request in a queue, the entry comprising a reference to the data block in the buffer, sends a write command to an SSD, the write command comprising the data block, and subsequently receives an acknowledgment that the data block has been written to the SSD. The processing device maintains the data block in the buffer until a combined size of a plurality of data blocks in the buffer is equal to or greater than a threshold, the threshold being based on a number of SSDs in the plurality of SSDs and a block size of the plurality of SSDs. |
