Instance Storage Types

The database system is generally an important system in the IT system and has 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. When striped across multiple disks, they can achieve up to 800 MB/s throughput.
  • Extreme SSD: Superfast disks ideal for workloads demanding ultra-high bandwidth and ultra-low latency. When striped across multiple disks, they can achieve up to 2,500 MB/s throughput.

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.
