This page describes the different storage types available for your Cloud SQL instances.
Cloud SQL offers different storage type options depending on the Cloud SQL edition and the machine series you select for your instance:
- Performance Persistent Disk (SSD): a persistent disk offering for high-performance databases and is backed by solid-state drives. This storage type is available for the Cloud SQL Enterprise Plus edition machine series, and the Cloud SQL Enterprise edition memory-optimized-N2 machine series.
For more information about the different machine series and types available for Cloud SQL, see Machine series overview.
Performance Persistent Disk
Cloud SQL uses the Performance Persistent Disk (SSD) storage option for its Memory-optimized-N2 machine series. SSD is a Persistent Disk volumes offering that provides durable network storage devices and is suitable for enterprise applications and high-performance databases that require lower latency and more IOPS. For more information, see About Persistent Disk.
IOPs and throughput for SSD storage type are set based on the machine type and storage capacity you set. You can't configure the values for IOPS and throughput.
N2 SSD IOPS and throughput limits
The following table shows the maximum values for IOPS and throughput for the SSD storage option based on the number of vCPUs for the N2 machine series:
| vCPUs | Maximum write IOPS | Maximum read IOPS | Maximum write throughput (MB/s) | Maximum read throughput (MB/s) |
|---|---|---|---|---|
| 2 | 15,000 | 15,000 | 240 | 240 |
| 4 | 15,000 | 15,000 | 240 | 240 |
| 8 | 15,000 | 15,000 | 800 | 800 |
| 16 | 25,000 | 25,000 | 1,000 | 1,200 |
| 32 | 60,000 | 60,000 | 1,000 | 1,200 |
| 48 | 60,000 | 60,000 | 1,000 | 1,200 |
| 64 | 80,000 | 60,000 | 1,000 | 1,200 |
| 80 | 80,000 | 60,000 | 1,000 | 1,200 |
| 96 | 80,000 | 60,000 | 1,000 | 1,200 |
| 128 | 80,000 | 60,000 | 1,000 | 1,200 |
