 ### Prerequisites
+Depending of the protocol you use, refer to the following sections to configure the requirements for the CSI Driver.
 
-#### Fibre Channel requirements
-
-Dell PowerStore supports Fibre Channel communication. If you use the Fibre Channel protocol, ensure that the
-following requirement is met before you install the CSI Driver for Dell PowerStore:
-- Zoning of the Host Bus Adapters (HBAs) to the Fibre Channel port must be done.

-#### Set up the iSCSI Initiator
-The CSI Driver for Dell PowerStore v1.4 and higher supports iSCSI connectivity.

 If you use the iSCSI protocol, set up the iSCSI initiators as follows:
 - Ensure that the iSCSI initiators are available on both Controller and Worker nodes.
 - Kubernetes nodes must have access (network connectivity) to an iSCSI port on the Dell PowerStore array that
-has IP interfaces. Manually create IP routes for each node that connects to the Dell PowerStore.
+has IP interfaces.
 - All Kubernetes nodes must have the _iscsi-initiator-utils_ package for CentOS/RHEL or _open-iscsi_ package for Ubuntu installed, and the _iscsid_ service must be enabled and running.
 To do this, run the `systemctl enable --now iscsid` command.
 - Ensure that the unique initiator name is set in _/etc/iscsi/initiatorname.iscsi_.
 
 For information about configuring iSCSI, see _Dell PowerStore documentation_ on Dell Support.
