Hybrid-storage instances are retired. For more information, see End-of-sale for Tair hybrid-storage instances. We recommend that you choose persistent memory-optimized instances.
This page lists the specifications for Standard Edition Tair (Enterprise Edition) hybrid-storage instances, including memory capacity, disk capacity, connections, bandwidth, and reference queries per second (QPS) values.

CPU core notes
One CPU core is reserved for background tasks to maintain service stability. In a cluster instance or a read/write splitting instance, one CPU core is reserved per shard or read replica.
Bandwidth notes
The bandwidth value in the table is the maximum for that instance type, representing the combined bandwidth across all shards or nodes.
Bandwidth limits apply symmetrically to upstream and downstream traffic. For example, a 48 MB/s instance has 48 MB/s upstream and 48 MB/s downstream.
For Tair and Redis Open-Source Edition, bandwidth limits reflect the data transfer capacity of individual shards within their respective distributed systems. These limits are generally independent of the network connection type used by clients.
To handle unexpected or scheduled traffic peaks, adjust the bandwidth of your instance. For details, see Manually increase the bandwidth of an instance. For common bandwidth questions, see FAQ about bandwidth.
