This section introduces the product specifications of DCS Redis 2.8, Redis 4.0 and Redis 5.0 instances, including memory specifications, available memory, maximum number of connections, maximum bandwidth/baseline bandwidth (in Gbps), and maximum packets sent and received (in 10,000 pps).
l Memory: You can check the remaining memory of each node in the node management list in the console. For specific operations, see Viewing Redis Cluster Information.
l Maximum number of connections: The number of concurrent connections, indicating the number of client connections allowed at the same time. You can check the number of connections for a certain instance in the console. For specific operations, see Instance Indicator Monitoring. The maximum number of connections can be modified in the console after the instance is created. For specific operations, see Frontend Configuration.
l QPS: Queries Per Second, indicating the number of commands executed by the Redis instance per second.
l Maximum bandwidth: Indicates the bandwidth of a single shard of the Redis instance. The maximum bandwidth applies to the uplink bandwidth and downlink bandwidth. If the bandwidth of an instance is 0.8Gbp, both the uplink and downlink bandwidths of this instance specification are 0.8Gbp.
l Baseline bandwidth: The Internet bandwidth depends on the intranet bandwidth and is also limited by the network bandwidth between the Redis instance and the client. It is recommended to use the intranet for connection to avoid the influence of the Internet and maximize bandwidth performance.
l Maximum packets sent and received: The maximum number of data packets that can be transmitted between a Redis instance and the client.
