Selecting the appropriate service level and allocated capacity for NetApp Cloud Volumes Service

The cost for Cloud Volumes Service for Google Cloud is based on the service level and the allocated capacity that you select. Selecting the appropriate service level and capacity helps you meet your storage needs at the lowest cost.

Storage considerations

Storage needs include two fundamental aspects:

  • The storage capacity for holding data.
  • The storage bandwidth for interacting with data.

If you consume more storage space than the capacity you selected for the volume, the following considerations apply:

  • You will be billed for the additional storage capacity that you consume at the price defined by your service level.
  • The amount of storage bandwidth available to the volume does not increase until you increase the allocated capacity size or change the service level.

Service levels

Cloud Volumes Service for Google Cloud supports three service levels for CVS-Performance service type volumes. You specify your service level when you create or modify the volume.

The service levels are designed for different storage capacity and storage bandwidth needs:

  • Standard (capacity)

    If you want capacity at the lowest cost, and your bandwidth needs are limited, then the Standard service level might be most appropriate for you. An example is using the volume as a file-share target.

    • List price
    • Bandwidth: 16 KiB of bandwidth per GiB provisioned capacity
  • Premium (a balance of capacity and performance)

    If your app has a balanced need for storage capacity and bandwidth, then the Premium service level might be most appropriate for you. This level is less expensive per MiB/s than the Standard service level, and it is also less expensive per GiB of storage capacity than the Extreme service level.

    • List price
    • Bandwidth: 64 KiB of bandwidth per GiB provisioned capacity
  • Extreme (performance)

    The Extreme service level is least expensive in terms of storage bandwidth. If your app demands storage bandwidth without the associated demand for lots of storage capacity, then the Extreme service level might be most appropriate for you.

    • List price
    • Bandwidth: 128 KiB of bandwidth per GiB provisioned capacity

Allocated capacity

You specify your allocated capacity for the volume when you create or modify the volume.

While you would select your service level based on your general, high-level business needs, you should select your allocated capacity size based on the needs of apps, for example:

  • How much storage space the apps need.
  • How much storage bandwidth per second the apps or the users require.

Allocated capacity is specified in GiBs. A volume's allocated capacity can be set within the range of 1024 GiB to 102,400 GiB (equivalent to 100 TiBs).

Bandwidth

The combination of both the service level and the allocated capacity you select determines the maximum bandwidth for the volume.

If your apps or users need more bandwidth than your selections, you can change the service level or increase the allocated capacity. The changes do not disrupt data access.

Selecting the service level and the allocated capacity

To select the most appropriate service level and allocated capacity for your needs, you need to know how much capacity and bandwidth you require at the peak or the edge.

Cost comparison for service levels and allocated capacity

The following table compares the cost for different service levels and allocated capacity sizes. In the table, the first column indicates the capacity, and the other columns define the maximum read throughput in MiB/s available at each capacity point and its cost per month.

Examples of cost structure

The following examples illustrate two scenarios for selecting the appropriate service level.

Example 1

For example, your app requires 25 TiB of capacity and 100 MiB/s of bandwidth. At 25 TiB of capacity, the Standard service level would provide 400 MiB/s of bandwidth at a cost of $5,120 per month, making Standard the most suitable service level in this case.

Capacity Standard Premium Extreme
TiB MiB/s Cost MiB/s Cost MiB/s Cost
25 400 $5,120 1600 $7,680 3200 $10,240

Example 2

For example, your app requires 12 TiB of capacity and 800 MiB/s of peak bandwidth. Although the Extreme service level can meet the demands of the app at the 12 TiB mark, it is more cost-effective to select 13 TiB at the Premium service level.

Capacity Standard Premium Extreme
TiB MiB/s Cost MiB/s Cost MiB/s Cost
12 192 $2,458 768 $3,686 1536 $4,915
13 208 $2,662 832 $3,994 1664 $5,325
