SED Key Group

Overview

This function displays the key group settings for the RAID groups that are configured with SEDs.

Note

  • One key group can be created in the storage system.

  • Use the [Key Group] screen to check the SED authentication key information and the SSL/KMIP certificate information that is used for the key group. Refer to the [Key Group] function for details.

  • There are two types of SED keys: an SED authentication key that is managed by the key server and a common key that is stored in the storage system. If a RAID group that is configured with SEDs is registered in the key group, the relevant RAID group is managed by the SED authentication key. If the RAID group is not registered in the key group, the relevant RAID group is managed by the common key.

  • RAID groups that are configured with SEDs can be added in the key group or deleted from the key group. Refer to the [Set Key Group (RAID Group)] function for details.
