This section describes how to create an account. After that, the system can allocate independent private storage space for it, including space and file quantity quotas. An account can obtain complete storage services and be isolated from other account resources.
After an account is created, the system automatically creates a local UNIX authentication user or user group and a local Windows authentication user group for the account.
The Create Account page is displayed.
Parameter |
Description |
|
|---|---|---|
Space Quota |
Hard Quota |
If the used file space reaches the space hard quota, the system immediately forbids writes and reports an alarm. The file space that exceeds the hard quota cannot be used. [Value range] 1 KB to 256 PB The value must be greater than those of Soft Quota and Advisory Quota.
NOTE:
If the used file space reaches the hard quota, the system forbids writes. If you want the system to report an alarm before writes are forbidden, set a soft quota and an advisory quota. |
Soft Quota |
If the used file space reaches the space soft quota, the system reports an alarm but still allows writes. If the soft quota grace period elapses or hard quota is reached, the system immediately forbids writes and reports an alarm. [Value range] 1 KB to 256 PB The value must be greater than that of Advisory Quota and less than that of Hard Quota. |
|
Advisory Quota |
If the used file space reaches the space advisory quota, the system reports an alarm but still allows writes. [Value range] 1 KB to 256 PB The value must be less than those of Soft Quota and Hard Quota. |
|
Collect Snapshot Space Statistics |
Whether to collect statistics of the snapshot space included in the used file space. |
|
File Quantity Quota |
Hard Quota (K) |
If the number of files reaches the file quantity hard quota, the system reports an alarm and new files cannot be added. However, operations on existing files are not affected. The unit is thousands. [Value range] 1 to 100,000,000 The value must be greater than those of Soft Quota (K) and Advisory Quota (K).
NOTE:
If the number of files reaches the hard quota, the system forbids file adding. If you want the system to report an alarm before files cannot be added, set a soft quota and an advisory quota. |
Soft Quota (K) |
If the number of files reaches the file quantity soft quota, the system reports an alarm but new files can still be added. If the soft quota grace period elapses or hard quota is reached, new files cannot be added and an alarm is reported. The unit is thousands. [Value range] 1 to 100,000,000 The value must be greater than that of Advisory Quota (K) and less than that of Hard Quota (K). |
|
Advisory Quota (K) |
If the number of files reaches the advisory quota, the system reports an alarm but new files can still be added. [Value range] 1 to 100,000,000 The value must be less than those of Soft Quota (K) and Hard Quota (K). |
|
Grace Period |
Soft Quota Grace Period (Days) |
If the used file space or number of files reaches the soft quota, the system generates an alarm but still allows writes or new files can still be added within this period. If this period elapses, the system immediately forbids writes and new files cannot be added. In addition, an alarm is reported. [Value range] 1 to 4,294,967,294. If this parameter is not specified, the grace period is unlimited. In this case, if the used file space or number of files reaches the soft quota, the system reports an alarm but does not restrict users' writing data or adding new files.
NOTE:
This parameter can be set only when Soft Quota or Soft Quota (K) is set. |
If you need to encrypt user data to ensure data security, enable data encryption for the account first. When creating a namespace, you can enable data encryption for the namespace separately.
After data encryption is enabled for an account, the system generates an account key. After data encryption is enabled of a namespace, the system generates a data key. The account key is used to protect the data key of the namespace, and the data key is used to encrypt and decrypt user data.
Table 3 describes related parameters.
Parameter |
Description |
|---|---|
OPS Upper Limits |
OPS upper limit of a single account, that is, the maximum number of operations performed by an account per second. |
Bandwidth Upper Limits |
Bandwidth upper limit of a single account, that is, the maximum amount of I/O data that can be processed by a single account per second, in MB/s. |
The system generates the AK and SK of the current account. Keep the AK and SK secure and do not disclose them to others.
After the account is created, you can select Configure LDAP Domain, Configure NIS Domain, Configure AD Domain, Configure Kerberos Realm, or Configure DNS on the operation success page.
