General Purpose SSD V2 Disks

General Purpose SSD V2 disks provide a baseline IOPS of 3,000 and a baseline throughput of 125 MiB/s regardless of the disk capacity.

With the General Purpose SSD V2 type, you can buy disks with the IOPS and throughput tailored to your workloads. The disk performance no longer changes with the disk capacity.

Short description

General-purpose SSD-backed disks targeting for transactional workloads with optimized performance and cost

Typical scenarios
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)

Max. IOPS

128,000

Max. throughput

1,000 MiB/s

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 multiplying 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.

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.

Configuration

  1. Go to the Buy Disk page.
  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 Purchasing an EVS Disk.

  3. Click Next.

    • If you select Yearly/Monthly for Billing Mode:
      1. Check the disk details on the Confirm page.
      2. Confirm the information and click Submit.
      3. On the Pay page, select a desired payment method and confirm the payment. The system displays a message indicating payment processed successfully.
      4. Click Back to Elastic Volume Service to return to the Elastic Volume Service page.
    • If you select Pay-per-use for Billing Mode:
      1. Check the disk details on the Confirm page.
      2. Confirm the information and click Submit. The system displays a message indicating request submitted successfully.
      3. Click Back to Disk List to return to the Elastic Volume Service page.

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.

Billing Examples

Example 1: Purchasing a yearly/monthly General Purpose SSD V2 disk

A customer purchases 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, the customer is billed for $351.392 (Capacity charge + IOPS charge + throughput charge = 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).

  • Capacity charge = Yearly/Monthly capacity charge
  • IOPS charge = (Preconfigured IOPS – Baseline IOPS) x IOPS unit price x Duration
  • Throughput charge = (Preconfigured throughput – Baseline throughput) x Throughput unit price x Duration

Example 2: Purchasing a pay-per-use General Purpose SSD V2 disk

A customer purchases 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, the customer is billed for $11.7344 (Capacity charge + IOPS charge + throughput charge = 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).

  • Capacity charge = Capacity x Storage unit price x Duration
  • IOPS charge = (Preconfigured IOPS – Baseline IOPS) x IOPS unit price x Duration
  • Throughput charge = (Preconfigured throughput – Baseline throughput) x Throughput unit price x Duration
