Cloud Block Storage quotas

All new Cloud Block Storage users are assigned default quotas that limit the amount of block storage that can be provisioned in each region. Default quotas enable users to provision up to 10 TB of SATA and 10 TB of SSD and are primarily used to help with capacity planning and to prevent system abuse. If your application requires more storage or volumes than the default quotas, simply submit a support request to ask for an increase. In your request, be sure to include the following information:

• Total storage amount that you need (in GBs or TBs)

• Storage type (SATA or SSD)

• Region (for example, DFW or LON)

Note

Cloud Block Storage quotas are independent from any other account quotas that you might have. In addition, Cloud Block Storage no longer supports account quotas (previously shared by SATA and SSD) or number-of-volumes quotas. Both of these quotas were replaced by the storage-type quotas, which are specific to SATA and SSD per account per region.

You can use the OpenStack Cinder client or API to see your current block storage quota and your current utilization against it.

For Cinder client users, use the following command:

$ cinder quota-usage yourAccountID

Your account ID or account number is often referred to as your tenant ID or tenant name. For information about how to find your account ID, see the Authentication section.

This results in a quota listing similar to the following example.

Example: Response showing quota and usage information

+----------------+--------+----------+-------+
|      Type      | In_use | Reserved | Limit |
+----------------+--------+----------+-------+
|   gigabytes    |  100   |    0     |   -1  |
| gigabytes_SATA |  100   |    0     | 10240 |
| gigabytes_SSD  |   0    |    0     | 10240 |
|   snapshots    |  12    |    0     |   -1  |
| snapshots_SATA |   1    |    0     |   -1  |
| snapshots_SSD  |   0    |    0     |   -1  |
|    volumes     |   1    |    0     |   -1  |
|  volumes_SATA  |   1    |    0     |   -1  |
|  volumes_SSD   |   0    |    0     |   -1  |
+----------------+--------+----------+-------+

The following table describes the information in the quota listing.

Table: Cloud Block Storage quota properties

Property name	Value description
gigabytes	Volume gigabytes allowed for each tenant. Gigabytes for SATA and SSD are given.
snapshots	Volume snapshots allowed for each tenant. Snapshots for SATA and SSD are given.
volumes	Volumes allowed for each tenant. Volumes for SATA and SSD are given.

To use the Cinder API, you can use a cURL request similar to the following example to see your current block storage quota and your current activity against it. If you use the usage=True query parameter, the response includes the usage information. If you do not include the query parameter, the response includes only quota information.

Example: cURL request to show quota and usage information

curl -i -X GET https://dfw.blockstorage.api.rackspacecloud.com/v1/yourAccountID/os-quota-sets/yourAccountID?usage=True \
-H "X-Auth-Project-Id: yourAccountID" \
-H "User-Agent: python-cinderclient" \
-H "Accept: application/json" \
-H "X-Auth-Token: yourAuthToken"

Example: Response from the cURL request to show quota and usage information
