Instance Specifications

This section describes available GeminiDB Redis instance specifications. The instance specifications depend on the selected CPU model.

GeminiDB Redis API allows for cold and hot data exchange and has the ability to handle a capacity that surpasses the limitations of memory. Hot data is stored in the memory, and full data is stored in the high-performance storage pool. The total instance space refers to the total storage capacity, which determines the upper limit of data storage. Table 3 lists the node memory capacity.

The bandwidth of some old instances is lower than the bandwidth baseline of the preceding nodes with same specifications. You need to attention to the bandwidth usage. If the traffic of old instances is heavy, you can submit a service ticket to change the bandwidth.
