Instance Storage Types

Database systems are one of the most important IT systems and have high requirements on storage I/O performance. GaussDB supports ultra-high I/O and extreme SSD storage types.

Ultra-high I/O: Ultra-high performance cloud disks excellent for enterprise mission-critical services as well as workloads demanding high throughput and low latency. For details, see the descriptions of "Ultra-high I/O" in Disk Types and Performance.
Extreme SSD: Superfast disks ideal for workloads demanding ultra-high bandwidth and ultra-low latency. For details, see the descriptions of "Extreme SSD" in Disk Types and Performance.

To apply for the permissions needed for using the extreme SSD storage type, submit an application by choosing Service Tickets > Create Service Ticket in the upper right corner of the management console.
