Red Hat Summit12.2.4. Programação de múltiplas filas em dispositivos de bloco
Os dispositivos de bloco agora usam o agendamento de múltiplas filas no Red Hat Enterprise Linux 8. Isto permite que o desempenho da camada de bloco seja bem dimensionado com drives de estado sólido rápido (SSDs) e sistemas multi-core.
O driver SCSI Multiqueue (scsi-mq) está agora habilitado por padrão, e o kernel boots com a opção scsi_mod.use_blk_mq=Y. Esta mudança é consistente com o kernel Linux upstream.
O Device Mapper Multipath (DM Multipath) requer que o driver scsi-mq esteja ativo.
