• Select the “Storage” main menu item on the left of the screen.

• Select the “ZFS Pool manager” sub menu tab.

• The main area will then display the list of all available pools along with the datasets/block device volumes in each of the pools.

• Corresponding to each pool, you will see a button saying “View pool details”. Clicking on this will take you to a screen that displays the pool details.

• You will then see a button that says “Change the write cache device”. You can then use this to either select a RAMDisk with a specific size as the write cache.
