Add the newly added ssd panel to the compute panel group under the administrator (admin) and name it Ssd.

cat /usr/share/openstack-dashboard/openstack_dashboard/enabled/_2160_admin_ssd_panel.py
# The slug of the panel to be added to HORIZON_CONFIG. Required.
PANEL = 'ssd'
# The slug of the dashboard the PANEL associated with. Required.
PANEL_DASHBOARD = 'admin'
# The slug of the panel group the PANEL is associated with.
PANEL_GROUP = 'compute'
# Python panel class of the PANEL to be added.
ADD_PANEL = 'openstack_dashboard.dashboards.admin.ssd.panel.Ssd'

Restart http

systemctl restart httpd.service

Up to this point, a new Ssd panel has been added to the dashboard, and functions need to be added later.
