+Support for Windows was introduced in `v1.7.0`. Currently support is limited

+simultaneously).

+# Storage Class Parameters
+
+Some drivers support different settings for volumes. These can be configured via the driver configuration and/or storage
+classes.
+
+## `synology-iscsi`
+The `synology-iscsi` driver supports several storage class parameters. Note however that not all parameters/values are
+supported for all backing file systems and LUN type. The following options are available:
+
+### Configure Storage Classes
+```yaml
+apiVersion: storage.k8s.io/v1
+kind: StorageClass
+metadata:
+  name: synology-iscsi
+parameters:
+    fsType: ext4
+    # The following options affect the LUN representing the volume. These options are passed directly to the Synology API.
+    # The following options are known.
+    lunTemplate: |
+      type: BLUN       # Btrfs thin provisioning
+      type: BLUN_THICK # Btrfs thick provisioning
+      type: THIN       # Ext4 thin provisioning
+      type: ADV        # Ext4 thin provisioning with legacy advanced feature set
+      type: FILE       # Ext4 thick provisioning
+      description: Some Description
+      
+      # Only for thick provisioned volumes. Known values:
+      # 0: Buffered Writes
+      # 3: Direct Write
+      direct_io_pattern: 0
+      
+      # Device Attributes. See below for more info
+      dev_attribs:
+      - dev_attrib: emulate_tpws
+        enable: 1
+      - ...
+
+    # The following options affect the iSCSI target. These options will be passed directly to the Synology API.
+    # The following options are known.
+    targetTemplate: |
+      has_header_checksum: false
+      has_data_checksum: false
+      
+      # Note that this option requires a compatible filesystem. Use 0 for unlimited sessions.
+      max_sessions: 0
+      multi_sessions: true
+      max_recv_seg_bytes: 262144
+      max_send_seg_bytes: 262144
+
+      # Use this to disable authentication. To configure authentication see below
+      auth_type: 0
+```
+
+#### About LUN Types
+The availability of the different types of LUNs depends on the filesystem used on your Synology volume. For Btrfs volumes
+you can use `BLUN` and `BLUN_THICK` volumes. For Ext4 volumes you can use `THIN`, `ADV` or `FILE` volumes. These
+correspond to the options available in the UI.
+
+#### About `dev_attribs`
+Most of the LUN options are configured via the `dev_attribs` list. This list can be specified both in the `lunTemplate`
+of the global configuration and in the `lunTemplate` of the `StorageClass`. If both lists are present they will be merged
+(with the `StorageClass` taking precedence). The following  `dev_attribs` are known to work:
+
+- `emulate_tpws`: Hardware-assisted zeroing
+- `emulate_caw`: Hardware-assisted locking
+- `emulate_3pc`: Hardware-assisted data transfer
+- `emulate_tpu`: Space Reclamation
+- `emulate_fua_write`: Enable the FUA iSCSI command (DSM 7+)
+- `emulate_sync_cache`: Enable the Sync Cache iSCSI command (DSM 7+)
+- `can_snapshot`: Enable snapshots for this volume. Only works for thin provisioned volumes.
+
+### Configure Snapshot Classes
+`synology-iscsi` can also configure different parameters on snapshot classes:
+
+```yaml
+apiVersion: snapshot.storage.k8s.io/v1
+kind: VolumeSnapshotClass
+metadata:
+  name: synology-iscsi-snapshot
+parameters:
+  # This inline yaml object will be passed to the Synology API when creating the snapshot.
+  lunSnapshotTemplate: |
+    is_locked: true
+    
+    # https://kb.synology.com/en-me/DSM/tutorial/What_is_file_system_consistent_snapshot
+    # Note that app consistent snapshots require a working Synology Storage Console. Otherwise both values will have
+    # equivalent behavior.
+    is_app_consistent: true
+...
+```
+
+Note that it is currently not supported by Synology devices to restore a snapshot onto a different volume. You can
+create volumes from snapshots, but you should use the same `StorageClass` as the original volume of the snapshot did. 
+
+### Enabling CHAP Authentication
+You can enable CHAP Authentication for `StorageClass`es by supplying an appropriate `StorageClass` secret (see the
+[documentation](https://kubernetes-csi.github.io/docs/secrets-and-credentials-storage-class.html) for more details). You
+can use the same password for alle volumes of a `StorageClass` or use different passwords per volume.
+
+```yaml
+apiVersion: storage.k8s.io/v1
+kind: StorageClass
+metadata:
+  name: synology-iscsi-chap
+parameters:
+  fsType: ext4
+  lunTemplate: |
+    type: BLUN
+    description: iSCSI volumes with CHAP Authentication
+secrets:
+  # Use this to configure a single set of credentials for all volumes of this StorageClass
+  csi.storage.k8s.io/provisioner-secret-name: chap-secret
+  csi.storage.k8s.io/provisioner-secret-namespace: default
+  # Use substitutions to use different credentials for volumes based on the PVC
+  csi.storage.k8s.io/provisioner-secret-name: "${pvc.name}-chap-secret"
+  csi.storage.k8s.io/provisioner-secret-namespace: "${pvc.namespace}"
+...
+---
+# Use a secret like this to supply CHAP credentials.
+apiVersion: v1
+kind: Secret
+metadata:
+  name: chap-secret
+stringData:
+  # Client Credentials
+  user: client
+  password: MySecretPassword
+  # Mutual CHAP Credentials. If these are specified mutual CHAP will be enabled.
+  mutualUser: server
+  mutualPassword: MyOtherPassword
+```
+
+Note that CHAP authentication will only be enabled if the secret contains a username and password. If e.g. a password is
+missing CHAP authentication will not be enabled (but the volume will still be created). You cannot automatically
+enable/disable CHAP or change the password after the volume has been created.
+
+If the secret itself is referenced but not present, the volume will not be created.
