34. Type: Select iSCSI.

Alternatively, the initiator name can be obtained from the VRM Configurator or the Web
interface of a device.

5.5 Creating LUNs
38. Calculate the size for each LUN.
In the navigation panel, select Volumes > Manage. Here, the available size of the volume
is displayed. Divide that value by 16 to get the size of each individual LUN.
i
NOTICE!
Each storage system needs a minimum of 16 LUNs to provide the best performance.
A total of 16 LUNs is considered best practice.
If you already know that you will add additional storage shelves, you may consider to create
less than 16 LUNs here, as additional LUNs will be created for the additional volumes. In that
case, divide the size available for the volume by the number of LUNs you plan to create for the
volume.
Example: For a total of four volumes you might want to create four LUNs for each volume,
giving you a total of 16 LUNs.
