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^1^ For instructions on adjusting the maximum client connection limit,\nsee [Configure an instance](/memorystore/docs/cluster/configure-instances).\n\n### Cluster usage units\n\nThe per-project cluster usage units for a Memorystore for Redis Cluster instance is\ncalculated by the following formula:\n\nCluster usage units = (shard_count) \\* (1 + replica_count)\n\nThe regional quota for Memorystore for Redis Cluster limits the total amount of usage\nunits that you can provision across all of your Memorystore for Redis Cluster instances\nin a region.\n\nFor example, if you provision three instances in your project with 3 shards and\n1 replica each in `us-central1`, you have consumed 18 units out of the total\nregional unit quota for `us-central1`. To request a higher quota for a region,\nsee [Regional cluster usage unit quota increases](/memorystore/docs/cluster/quotas#regional_cluster_usage_unit_quota_increases).\n\n### Regional cluster usage unit quota increases\n\nTo request a higher regional capacity for your project, follow these steps:\n\n1. Go to the **Quotas** page in the Google Cloud console.\n\n [Quotas](https://console.cloud.google.com/iam-admin/quotas)\n\n2. From the **Services** drop down, select **Memorystore for Redis Cluster API**.\n\n3. From the list of quotas, click the checkbox next to the quota labeled **Total Redis Cluster units per project per region** for the desired region.\n\n4. Click the **Edit Quotas** button.\n\n5. In the edit pane, enter your contact information, then click **Next**.\n\n6. Enter your desired quota, then click **Done**.\n\n7. Click **Submit request**.\n\nPer-minute API requests quota\n-----------------------------\n\n| **Note:**\n| - You cannot request a quota increase for Memorystore for Redis Cluster API operations, such as instance `create`, `update`, and `delete`. There is no limit to the number of Redis commands you can run, such as Redis `SET`, `GET`, and `DEL`.\n| - Follow the [Exponential backoff recommendations](/memorystore/docs/redis/exponential-backoff) to reduce the number of API requests made if an error is encountered.\n\nThe per-minute quotas for Memorystore for Redis API requests/operations are as follows, and are subject to change:\n\nCreate or delete Redis Cluster requests include:\n\n- Create operations (`gcloud redis clusters create`)\n- Delete operations (`gcloud redis clusters delete`)\n\nMemorystore for Redis Cluster API operations include:\n\n- Get operations (`gcloud redis clusters describe`)\n- List operations (`gcloud redis clusters list`)\n- Create operations (`gcloud redis clusters create`)\n- Delete operations (`gcloud redis clusters delete`)\n- Update operations (`gcloud redis clusters update`)\n\nThis quota is for redis.googleapis.com requests/operations, not OSS Redis\nprotocol/commands. These limits apply to each Google Cloud console project and\nare shared across all applications and IP addresses using that project."]]
