FalconStor FSS Storage Fibre Channel and iSCSI drivers¶
The FSSISCSIDriver and FSSFCDriver drivers run volume operations
by communicating with the FalconStor FSS storage system over HTTP.
System requirements¶
To use the FalconStor FSS drivers, the following are required:
- FalconStor FSS storage with:
- iSCSI or FC host interfaces
- FSS-8.00-8865 or later
Supported operations¶
The FalconStor volume driver provides the following Cinder volume operations:
- Create, delete, attach, and detach volumes.
- Create, list, and delete volume snapshots.
- Create a volume from a snapshot.
- Clone a volume.
- Extend a volume.
- Get volume statistics.
- Create and delete consistency group.
- Create and delete consistency group snapshots.
- Modify consistency groups.
- Manage and unmanage a volume.
iSCSI configuration¶
Use the following instructions to update the configuration file for iSCSI:
default_volume_type = FSS
enabled_backends = FSS
[FSS]
# IP address of FSS server
san_ip = 172.23.0.1
# FSS server user name
san_login = Admin
# FSS server password
san_password = secret
# FSS server storage pool id list
fss_pools=P:2,O:3
# Name to give this storage back-end
volume_backend_name = FSSISCSIDriver
# The iSCSI driver to load
volume_driver = cinder.volume.drivers.falconstor.iscsi.FSSISCSIDriver
# ==Optional settings==
# Enable FSS log message
fss_debug = true
# Enable FSS thin provision
san_thin_provision=true
Fibre Channel configuration¶
Use the following instructions to update the configuration file for fibre channel:
default_volume_type = FSSFC
enabled_backends = FSSFC
[FSSFC]
# IP address of FSS server
san_ip = 172.23.0.2
# FSS server user name
san_login = Admin
# FSS server password
san_password = secret
# FSS server storage pool id list
fss_pools=A:1
# Name to give this storage back-end
volume_backend_name = FSSFCDriver
# The FC driver to load
volume_driver = cinder.volume.drivers.falconstor.fc.FSSFCDriver
# ==Optional settings==
# Enable FSS log message
fss_debug = true
# Enable FSS thin provision
san_thin_provision=true
Driver options¶
The following table contains the configuration options specific to the FalconStor FSS storage volume driver.
| Configuration option = Default value | Description |
|---|---|
| [DEFAULT] | |
additional_retry_list = |
(String) FSS additional retry list, separate by ; |
fss_debug = False |
(Boolean) Enable HTTP debugging to FSS |
fss_pools = {} |
(Dict) FSS pool ID list in which FalconStor volumes are stored. If you have only one pool, use A:<pool-id>. You can also have up to two storage pools, P for primary and O for all supporting devices. The usage is P:<primary-pool-id>,O:<others-pool-id> |
fss_san_secondary_ip = |
(String) Specifies FSS secondary management IP to be used if san_ip is invalid or becomes inaccessible. |
san_thin_provision = |
(Boolean) Enable FSS thin provision. |
