General Purpose SSD V2 Disks¶
General Purpose SSD V2 is a next-generation General Purpose SSD disk type. You can buy General Purpose SSD V2 disks of a given capacity with the IOPS and throughput tailored to your workloads. The disk capacity and performance are decoupled. This section describes the performance, configuration, and billing of General Purpose SSD V2 disks.
Performance¶
Parameter | General Purpose SSD V2 |
|---|---|
Max. capacity |
|
Baseline IOPS | 3,000 |
Max. IOPS | 128,000 |
Baseline throughput | 125 MiB/s |
Max. throughput | 1,000 MiB/s |
Single-queue access latency | 1 ms |
Burst IOPS limit | N/A |
Disk IOPS | You preconfigure an IOPS ranging from 3,000 to 128,000. This IOPS must also be less than or equal to 500 times the capacity. |
Disk throughput | You preconfigure a throughput ranging from 125 to 1,000 MiB/s. This throughput must also be less than or equal to the IOPS divided by 4. |
API name Note This API name is the value of the volume_type parameter in the EVS API. It does not represent the type of the underlying hardware device. | GPSSD2 |
Typical scenarios | Mainstream high-performance, low-latency interactive applications

Configuration¶
Go to the page for purchasing EVS disks.
Configure the disk parameters.
Choose the General Purpose SSD V2 type and enter a desired disk size.
Configure a desired IOPS.
Configure a desired throughput.
Configure other parameters by referring to Creating an EVS Disk.
Note
If you do not have a clear IOPS: throughput ratio in mind, you are advised to use the ratio of 50:1. For example, if your planned throughput is 600 MiB/s, configure 30,000 for the IOPS; if your planned throughput is 1,000 MiB/s, configure 50,000 for the IOPS.
If the preconfigured IOPS or throughput cannot meet your service requirement or is way more than what your need, you can adjust them at any time.
