Target Details
This section describes the end-to-end iSCSI setup, including settings for the
iSCSI Initiator, Target, and establishing connections.
Setting Up Target IP Addresses in the
PowerVault™ NAS Storage Solution
Based on your system configuration (with one or two dedicated iSCSI NICs)
assign IP addresses to the iSCSI NICs. Use the IP address that you assigned to
the iSCSI NIC(s) in the Target Portals tab of the Initiator for discovery.
Configuring Microsoft
®
iSCSI Software Targets
Before configuring iSCSI Targets, you must create a few LUNs and reserve
storage space to create virtual disks for iSCSI Targets. The following section
provides step-by-step instructions to create storage space.
1 Configuring network settings on the iSCSI Target device—The
PowerVault NAS storage solution is configured to use DHCP for network
settings by default. The PowerVault NAS storage system is designed for
multi-path operations and is equipped with two RJ45 Ethernet connectors.
You can add an optional additional NIC. The PowerVault NAS
Configuration tasks window displays the basic settings.
NOTE:
It is recommended that you configure dedicated iSCSI NICs on
separate subnets and not on the public network.
NOTE:
It is important at this point to note that the storage solution LUN size
should not be confused with the size of the iSCSI Target. The iSCSI Target is
configured in a later step and is associated with the storage needed for a
particular application on the host server. It is recommended that the LUN size
on the storage hardware be as large as reasonably possible to allow the
storage subsystem to optimize the use of the physical disks underlying the
LUN that is created. In this case, as shown below, we are choosing to create
one LUN at the maximum size available for this hardware. This iSCSI LUN
cannot accommodate the iSCSI Targets that are created later, based on the
needs of the host application.
