Fuel Cinder NetApp plugin specification
Overview
The plugin can replace Cinder default backend in MOS by Cinder NetApp
backend or work in parallel. LVM over iSCSI
and
Ceph
are two choices, which can be used as a default
backend for Cinder. The plugin does not overwrite
enabled_backends
option that allows to use it with other
plugins for Cinder backends.
This repo contains all necessary files to build Cinder NetApp Fuel plugin.
Problem description
This integration should be supported with the upstream version of Fuel product. Mirantis Openstack 8.0 release has Pluggable Architecture feature, that prevents developers from bringing any changes to the core product. Instead, the NetApp integration functionality can be implemented as a plugin for Fuel.
- The plugin support following storage families:
-
- Clustered Data ONTAP
- Data ONTAP 7-Mode
- E-Series/EF-Series
User Story 1: Clustered Data ONTAP devices with NFS and iSCSI modes
This case will provide availability to configure OpenStack compute instances to access Clustered Data ONTAP storage systems. To enable this functionality following changes should be added.
Clustered Data ONTAP via NFS:
All cinder hosts should have following configuration in <cinder.conf>:
[cinder_netapp] volume_backend_name = cinder_netapp volume_driver = cinder.volume.drivers.netapp.common.NetAppDriver netapp_login = LOGIN netapp_password = PASSWORD netapp_server_hostname = SERVER_HOSTNAME netapp_server_port = netapp_transport_type = TRANSPORT_TYPE netapp_storage_family = ontap_cluster netapp_storage_protocol = nfs nfs_shares_config = /etc/cinder/shares.conf netapp_vserver = VSERVER
Where
netapp_login
,netapp_password
,$netapp_server_hostname
,netapp_transport_type
,netapp_storage_family
,netapp_storage_protocol
,netapp_vserver
should be configured through the Fuel Web UI in Cinder and NetApp integration section of the Settings tab.
- All compute hosts should satisfy following requirements:
nfs-common
should be installed- Ensure that
nfs
service is enabled and running in the system
Clustered Data ONTAP via iSCSI:
All cinder hosts should have following configuration in <cinder.conf>:
[cinder_netapp] volume_backend_name = cinder_netapp volume_driver = cinder.volume.drivers.netapp.common.NetAppDriver netapp_login = LOGIN netapp_password = PASSWORD netapp_server_hostname = SERVER_HOSTNAME netapp_server_port = netapp_transport_type = TRANSPORT_TYPE netapp_storage_family = ontap_cluster netapp_storage_protocol = iscsi netapp_vserver = VSERVER
Where
netapp_login
,netapp_password
,$netapp_server_hostname
,netapp_transport_type
,netapp_storage_family
,netapp_storage_protocol
,netapp_vserver
should be configured through the Fuel Web UI in Cinder and NetApp integration section of the Settings tab.
- All compute hosts should satisfy following requirements:
open-iscsi
andmultipath-tools
should be installed
User Story 2: Data ONTAP 7-Mode devices with NFS and iSCSI modes
This case will provide availability to configure OpenStack compute instances to access Data ONTAP 7-Mode storage systems. To enable this functionality following changes should be added:
Data ONTAP 7-Mode via NFS:
All cinder hosts should have following configuration in <cinder.conf>:
[cinder_netapp] volume_backend_name = cinder_netapp volume_driver = cinder.volume.drivers.netapp.common.NetAppDriver netapp_login = LOGIN netapp_password = PASSWORD netapp_server_hostname = SERVER_HOSTNAME netapp_server_port = netapp_transport_type = TRANSPORT_TYPE netapp_storage_family = ontap_7mode netapp_storage_protocol = nfs nfs_shares_config = /etc/cinder/shares.conf netapp_vfiler = VFILTER
Where
netapp_login
,netapp_password
,$netapp_server_hostname
,netapp_transport_type
,netapp_storage_family
,netapp_storage_protocol
,netapp_vfilter
should be configured through the Fuel Web UI in Cinder and NetApp integration section of the Settings tab.
- All compute hosts should satisfy following requirements:
nfs-common
should be installed.- Ensure that
nfs
service is enabled and running in the system
Data ONTAP 7-Mode via iSCSI:
All cinder hosts should have following configuration in <cinder.conf>:
[cinder_netapp] volume_backend_name = cinder_netapp volume_driver = cinder.volume.drivers.netapp.common.NetAppDriver netapp_login = LOGIN netapp_password = PASSWORD netapp_server_hostname = SERVER_HOSTNAME netapp_server_port = netapp_transport_type = TRANSPORT_TYPE netapp_storage_family = ontap_7mode netapp_storage_protocol = iscsi netapp_vfiler = VFILTER
Where
netapp_login
,netapp_password
,$netapp_server_hostname
,netapp_transport_type
,netapp_storage_family
,netapp_storage_protocol
,netapp_vfiler
should be configured through the Fuel Web UI in Cinder and NetApp integration section of the Settings tab.
- All compute hosts should satisfy following requirements:
open-iscsi
andmultipath-tools
should be installed
User Story 3: E-Series/EF-Series devices with iSCSI mode
This case will provide availability to configure OpenStack compute instances to access E-Series/EF-Series storage systems. To enable this functionality following changes should be added:
E-Series/EF-Series via iSCSI:
All cinder hosts should have following configuration in <cinder.conf>:
[cinder_netapp] volume_backend_name = cinder_netapp volume_driver = cinder.volume.drivers.netapp.common.NetAppDriver netapp_login = LOGIN netapp_password = PASSWORD netapp_server_hostname = SERVER_HOSTNAME netapp_server_port = netapp_transport_type = TRANSPORT_TYPE netapp_storage_family = eseries netapp_storage_protocol = iscsi netapp_host_type = linux_dm_mp netapp_controller_ips = CONTROLLER_IPS netapp_sa_password = SA_PASSWORD netapp_webservice_path= /devmgr/v2
Where
netapp_login
,netapp_password
,$netapp_server_hostname
,netapp_transport_type
,netapp_storage_family
,netapp_storage_protocol
,netapp_controller_ips
,netapp_sa_password
should be configured through the Fuel Web UI in Cinder and NetApp integration section of the Settings tab.
- All compute hosts should satisfy following requirements:
open-iscsi
andmultipath-tools
should be installed
Affects
REST API impact
None.
Upgrade impact
Upgrading should be tested explicitly with this plugin installed and NetApp storage enabled.
Security impact
This plugin uses credentials that were used during NetApp storage setup. No impact on OpenStack services.
Notifications impact
None.
Other end user impact
None.
Plugin impact
This plugin should not impact other plugins until they do not modify the same settings for Cinder configuration.
Other deployer impact
Developer impact
Documentation Impact
Reference to this plugin should be added to main Fuel documentation.
Implementation
Work Items
- Create fuel-plugin-cinder-netapp plugin
- Develop the Fuel Web UI part of the plugin
- Add puppet support for all configuration cases
- Write documentation (User Guide)
Dependencies
- Ubuntu 14.04 support in MOS
Testing
Plugin should pass functional tests executed manually.
Alternatives
There are no known alternatives for this plugin, although all steps can be performed manually.
