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 a single node of some existing instances is 768 Mbit/s, which is the same as that of other Redis Cloud services. If existing instances are subjected to heavy traffic, you can choose Service Tickets > Create Service Ticket in the upper right corner of the console to consult on the bandwidth usage.
