--num-master-local-ssds, --num-workers-local-ssds, --num-secondary-worker-local-ssds 플래그와 함께 gcloud dataproc clusters create 명령어를 사용하여 로컬 SSD를 클러스터의 마스터, 기본, 보조 워커 노드에 연결합니다.
로컬 SSD는 SCSI(소형 컴퓨터 시스템 인터페이스) 또는 NVME(비휘발성 메모리 익스프레스) 인터페이스를 사용하여 Dataproc VM에 연결할 수 있습니다(로컬 SSD 성능 참조).
기본 Dataproc 클러스터 VM 로컬 SSD 인터페이스는 SCSI 인터페이스입니다. gcloud dataproc clusters create 명령어를 --master-local-ssd-interface, --worker-local-ssd-interface, --secondary-worker-local-ssd-interface 플래그와 함께 사용하여 마스터, 기본, 보조 워커 노드에 대한 로컬 SSD 인터페이스를 지정합니다.
로컬 SSD는 SCSI(소형 컴퓨터 시스템 인터페이스) 또는 NVME(비휘발성 메모리 익스프레스) 인터페이스를 사용하여 Dataproc VM에 연결할 수 있습니다(로컬 SSD 성능 참조).
기본 Dataproc 클러스터 VM 로컬 SSD 인터페이스는 SCSI 인터페이스입니다. cluster.create API 요청의 masterConfig, workerConfig 및 secondaryWorkerConfigInstanceGroupConfig에서 localSsdInterface 필드를 설정하여 'SCSI' 또는 'NVME' 인터페이스를 지정하여 로컬 SSD를 클러스터의 마스터, 기본, 보조 워커 노드에 연결합니다.
콘솔
Google Cloud 콘솔의 Dataproc 클러스터 만들기 페이지에 있는 노드 구성 패널에서 클러스터를 만들고 로컬 SSD를 마스터, 기본, 보조 워커 노드에 연결합니다.
