Cloud Storage System Environment Settings

In HULFT Cloud Storage Option Ver.8.5.1 or higher, the total number of parallel uploads and the total number of parallel downloads (hereinafter referred to as total number of parallels) can be configured.

The settings of total number of parallels are applied to the uploads and downloads for all object storages.

Specify the total number of parallels in the Cloud Storage System Environment Settings.

The values that can be specified in the Cloud Storage System Environment Settings and the values that are used when not specified are shown below.

Table 2.27 Total number of parallels that can be specified in Cloud Storage System Environment Settings

Field Name

Setting Value

Value Used When Not Specified

Total Number of Parallel Downloads

2 to 999

48

Total Number of Parallel Uploads

2 to 999

32
Note

  • If you specify a value larger than the total number of parallels for the maximum number of parallels per transfer in the Receive Storage Management Information or the Send Storage Management Information, the maximum number of parallels per transfer is limited to the total number of parallels.

    Therefore, specify the values as follows:

    Total number of parallels ≥ Maximum number of parallels per transfer

  • If you change the Total Number of Parallel Downloads to a larger value than the value of "48" that is used when the field is not specified, the load on the system may be high depending on the operating environment. Be aware of this fact when you change the Total Number of Parallel Downloads.

  • If you change the Total Number of Parallel Uploads to a larger value than the value of "32" that is used when the field is not specified, the load on the system may be high depending on the operating environment. Be aware of this fact when you change the Total Number of Parallel Uploads.

Note

The Cloud Storage System Environment Settings cannot be registered when HULFT is running.

If you attempt to register a value in the Cloud Storage System Environment Settings when HULFT is running, the registration fails due to the exclusive lock.
