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.

Disk IOPS calculation formula |
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 calculation formula |
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. |

Typical use cases |
Mainstream high-performance, low-latency interactive applications

Configuration

If you do not have a clear throughput:IOPS ratio in mind, you are advised to use the ratio of 2:100 (with a throughput unit of 1 MiB/s and an IOPS unit of 100). For example, if your planned throughput is 200 MiB/s, configure 10,000 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.
- Go to the Buy Disk page.
- 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 Purchasing an EVS Disk.
- Click Next.
- If you select Yearly/Monthly for Billing Mode:
- Check the disk details on the confirmation page.
- Confirm the information and click Submit.
- On the Pay page, select a desired payment method and confirm the payment. The system displays a message indicating payment processed successfully.
- Click Back to Elastic Volume Service to return to the Elastic Volume Service page.
- If you select Pay-per-use for Billing Mode:
- Check the disk details on the confirmation page.
- Confirm the information and click Submit. The system displays a message indicating request submitted successfully.
- Click Go to Disk List to return to the Elastic Volume Service page.

Performance Modification
If the disk performance no longer meets your service requirements, you can modify its IOPS and throughput by changing the disk type.
Billing

Billing Formula |
Description |
---|---|---|
Capacity |
Capacity price = Yearly/Monthly capacity price |
IOPS and throughput are billed based on the preconfigured values. For more information, see EVS Pricing Details. |
IOPS |
IOPS price = (Preconfigured IOPS – Baseline IOPS) x IOPS unit price x Duration |
|
Throughput |
Throughput price = (Preconfigured throughput – Baseline throughput) x Throughput unit price x Duration |
Billing Item |
Billing Formula |
Description |
---|---|---|
Capacity |
Capacity price = Capacity x Capacity unit price x Duration |
IOPS and throughput are billed based on the preconfigured values. For more information, see EVS Pricing Details. |
IOPS |
IOPS price = (Preconfigured IOPS – Baseline IOPS) x IOPS unit price x Duration |
|
Throughput |
Throughput price = (Preconfigured throughput – Baseline throughput) x Throughput unit price x Duration |
Billing Examples
Example 1: Purchasing a yearly/monthly General Purpose SSD V2 disk
Suppose you purchased a 100-GiB General Purpose SSD V2 disk preconfigured with an IOPS of 5,000 and throughput of 325 MiB/s.
If the yearly/monthly capacity unit price is $0.5 per GiB per month, the pay-per-use IOPS unit price is $0.0000153 per IOPS per hour, and the pay-per-use throughput unit price is $0.00194 per MiB/s per hour:
One month (30 days) after purchasing the disk, you will be billed for $351.392 (Capacity price + IOPS price + throughput price = 100 x 0.5 x 1+ (5,000 – 3,000) x 0.0000153 x 24 x 30 + (325 – 125) x 0.00194 x 24 x 30 = 50 + 22.032 + 279.36 = 351.392).
Example 2: Purchasing a pay-per-use General Purpose SSD V2 disk
Suppose you purchased a 100-GiB General Purpose SSD V2 disk preconfigured with an IOPS of 5,000 and throughput of 325 MiB/s.
If the pay-per-use capacity unit price is $0.000695 per GiB per hour, the pay-per-use IOPS unit price is $0.0000153 per IOPS per hour, and the pay-per-use throughput unit price is $0.00194 per MiB/s per hour:
24 hours after purchasing the disk, you will be billed for $11.7344 (Capacity price + IOPS price + throughput price = 100 x 0.000695 x 24 + (5,000 – 3,000) x 0.0000153 x 24 + (325 – 125) x 0.00194 x 24 = 1.668 + 0.7344 + 9.312 = 11.7344).
