이 페이지에서는 Memorystore for Redis 클러스터 인스턴스를 확장하는 방법을 설명합니다.
인스턴스의 용량은 인스턴스의 샤드 수와 인스턴스의 노드 유형에 따라 결정됩니다.
인스턴스를 확장하려면 샤드 수 또는 노드 유형을 변경해야 합니다.
확장 중 인스턴스 동작에 대한 자세한 내용은 인스턴스 용량 확장 정보를 참고하세요.
샤드 수 확장
Google Cloud 콘솔 또는 Google Cloud CLI를 사용하여 인스턴스의 샤드 수를 늘리거나 줄일 수 있습니다.
콘솔
Google Cloud 콘솔에서 Memorystore for Redis Cluster 페이지로 이동합니다.
SHARD_COUNT: 인스턴스의 샤드 수입니다. 샤드 개수는 인스턴스 데이터를 저장하기 위한 총 메모리 용량을 결정합니다. Memorystore for Redis Cluster 인스턴스의 클러스터 및 노드 사양에 대한 자세한 내용은 클러스터 및 노드 사양을 참고하세요.

In the Google Cloud console, go to the **Memorystore for Redis Cluster** page.\n\n [Memorystore for Redis Cluster](https://console.cloud.google.com/memorystore/redis/clusters?)\n2. Click your cluster ID.\n\n3. In the **Configurations** section, click the pencil icon next to\n **Shards**.\n\n4. In the **Shards** field, enter the number of shards to which you want to\n scale your instance.\n\n5. Click **Update cluster**.\n\n### gcloud\n\nTo scale the number of shards for an instance, use the [`gcloud redis clusters update`](/sdk/gcloud/reference/redis/clusters/update) command: \n\n```\ngcloud redis clusters update INSTANCE_ID \\\n--region=REGION_ID \\\n--shard-count=SHARD_COUNT\n```\n\nReplace the following:\n\n- \u003cvar translate=\"no\"\u003eINSTANCE_ID\u003c/var\u003e: the ID of your instance.\n- \u003cvar translate=\"no\"\u003eREGION_ID\u003c/var\u003e: the region where your instance is located.\n- \u003cvar translate=\"no\"\u003eSHARD_COUNT\u003c/var\u003e: the number of shards in your instance. The shard count determines the total memory capacity for storing instance data. For more information about cluster and node specifications for Memorystore for Redis Cluster instances, see [Cluster and node specification](/memorystore/docs/cluster/cluster-node-specification).\n\nFor example: \n\n```\ngcloud redis clusters update my-instance \\\n--region=us-central1 \\\n--shard-count=8\n```\n\nScale the node type\n-------------------\n\nYou can scale the node type for an instance by using the [Google Cloud CLI](/sdk/gcloud). \n\n### gcloud\n\n1. To retrieve information about an instance, use the [`gcloud redis clusters describe`](/sdk/gcloud/reference/redis/clusters/describe) command:\n\n ```\n gcloud redis clusters describe INSTANCE_ID \\\n --region=REGION_ID\n ```\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eINSTANCE_ID\u003c/var\u003e: the ID of your instance\n - \u003cvar translate=\"no\"\u003eREGION_ID\u003c/var\u003e: the region where your instance is located (for example, `us-central1`)\n2. Check the output to see if the following conditions exist:\n\n 1. The output contains a `redisConfigs` section.\n\n 2. The `maxmemory-clients`, `maxmemory`, or `maxclients` parameters appear\n in this section.\n\n If any of these parameters appear, then when you scale the node type for the\n instance, you must scale the values for the parameters to reflect values\n that Memorystore for Redis Cluster can accept for the scaled node type. For more\n information, see [Modifiable configuration parameters](/memorystore/docs/cluster/supported-instance-configurations#modifiable_configuration_parameters).\n3. To scale the node type, use the [`gcloud redis clusters update`](/sdk/gcloud/reference/redis/clusters/update) command:\n\n ```\n gcloud redis clusters update INSTANCE_ID \\\n --region=REGION_ID \\\n --node-type=NODE_TYPE\n ```\n\n Replace the following:\n - \u003cvar translate=\"no\"\u003eINSTANCE_ID\u003c/var\u003e: the ID of your instance.\n - \u003cvar translate=\"no\"\u003eREGION_ID\u003c/var\u003e: the region where your instance is located.\n - \u003cvar translate=\"no\"\u003eNODE_TYPE\u003c/var\u003e: the node type to which you want to scale your\n instance. Acceptable values for this parameter are `redis-shared-core-nano`, `redis-standard-small`, `redis-highmem-medium`, and `redis-highmem-xlarge`.\n\n | **Note:** You can't scale your instance down to the `redis-shared-core-nano` node type.\n | **Caution** : We recommend that you use the `redis-shared-core-nano` node type for development or testing purposes only. If you run Memorystore for Redis Cluster in a production environment, then we recommend using the `redis-standard-small`, `redis-highmem-medium`, or `redis-highmem-xlarge` node types. For more information about these node types, see [Choose a node type](/memorystore/docs/cluster/cluster-node-specification#choose_a_node_type).\n\n For this example, you scale the node type of the `my-instance` instance to `redis-highmem-medium`. This instance is located in the `us-central1`\n region. \n\n ```\n gcloud redis clusters update my-instance \\\n --region=us-central1 \\\n --node-type=redis-highmem-medium\n ```\n\n For this example, you change the value of the `maxclients` parameter to\n `15,000`. \n\n ```\n gcloud redis clusters update my-instance \\\n --region=us-central1 \\\n --node-type=redis-highmem-medium \\\n --update-redis-config=maxclients=15000\n ```\n\n\u003cbr /\u003e"]]
