iSNS

iSNS (Internet Storage Name Service) provides the mechanism for centralized management. You can register all the iSCSI Targets with an iSNS server.

To register iSCSI targets with an iSNS server:

  1. Click iSNS and tick Enable iSNS.
  2. Enter the IP address of the iSNS server. Click OK to apply the setting.

I/O Queue Depth

The default setting is 16, but you can modify the I/O queue depth of all targets as needed.

Low-Capacity Write

When there is less than 1 GB of available space on a volume, the LUNs on the volume will become protected by the system to prevent filesystem crash, and users cannot write data to them. Low-Capacity Write will allow users to continue writing data to LUNs when the volume is running out of free space. However, you are advised to disable this option once you resolve the insufficient space issue.

Note:

Space Reclamation Mode

The following is three modes of space reclamation. By adjusting the speed, you can control the impact of space reclamation on LUN performance.
