![]() Make sure there are enough available IP addresses to accommodate the increase.Ĭommon pitfalls include the subnets in the subnet group have too small a CIDR range or the subnets are shared and heavily used by other clusters. ![]() ![]() For example, you can choose to configure a 500 node cluster that ranges betweenĨ3 shards (one primary and 5 replicas per shard) and 500 shards (single primary and no replicas). The node or shard limit can be increased to a maximum of 500 per cluster if the Redis engine version is 5.0.6 or higher.
