Optimizing disk I/O when running the Database Update task

When running the Database Update task, Kaspersky Security for Windows Server stores update files on the protected device's local disk. You can lower the workload on the protected device's disk I/O subsystem by storing update files on a virtual drive in RAM when running the update task.

This feature is available for Microsoft Windows 7 operating systems and higher.

When using this feature while running the Database Update task, an extra logical drive may appear in the operating system. This logical drive will be removed from the operating system after the task is completed.

To lower the workload on your protected devices's disk I/O subsystem during the Database Update task:

1. In the Application Console tree, expand the Update node.
2. Select the Database Update child node.
3. Click the Properties link in the results pane of the Database Update node.

   The Task settings window opens on the General tab.

4. In the Disk I/O usage optimization section, define the following settings:
   • Clear or select the Lower the load on the disk I/O check box.
     

     This check box enables or disables the disk subsystem optimization through storage of update files on a virtual drive in RAM.

     If the check box is selected, this function is enabled.

     The check box is cleared by default.

   • In the RAM used for optimization, MB field, specify the RAM volume (in MB). The operating system temporarily allocates the specified RAM volume to store update files while running the task. The default RAM size is 512 MB. The minimum RAM size is 400 MB.

     When running the Database Update task with the disk subsystem optimization feature enabled, one of the following may occur, depending on the amount of RAM allocated for the feature:

     • If the value is too small, the allocated amount of RAM might be insufficient to complete the database update task (for example, during the first update), which will lead to the completion of the task with an error.

       In this case, it is recommended to allocate more RAM for the disk subsystem optimization feature.

     • If the value is too large, at the start of the Database Update task, it might be impossible to create a virtual drive of a selected size in RAM. As a result, the disk subsystem optimization feature automatically disables, and the Database Update task runs without the optimization feature.

       In this case, it is recommended to allocate less RAM for the disk subsystem optimization feature.

5. Click OK.

The configured settings will be saved and applied at the next task start.
