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

Table 1 General Purpose SSD V2 performance

Parameter

General Purpose SSD V2

Max. capacity
  • System disk: 1,024 GiB
  • Data disk: 32,768 GiB

Single-queue access latency

1 ms

Burst IOPS limit

N/A

Disk IOPS calculation formula

You configure an IOPS ranging from 100 to 128,000. This IOPS must also be less than or equal to 500 times the capacity.

Disk throughput calculation formula

You configure a throughput ranging from 10 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 use cases
Mainstream high-performance, low-latency interactive applications
  • Enterprise OA and virtual desktops
  • Large-scale development and test environments
  • Transcoding services
  • System disks
  • Medium- and large-sized databases (SQL Server, Oracle, NoSQL, and PostgreSQL)

Configuration

  1. Go to the page for creating EVS disks.
  2. 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.

  3. After the disk is created, view it in the disk list.

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.
