  * When prompted for component to use, include all of them to be safe (but be sure to include the SSH server one)
  * When given the option - choose to continue your installation via ssh - this will give you the ability to easily set and record pass phrases
- * Drive partioning. If you are using 2TB disks or greater... Open a new ssh session and choose to switch to console.
+ * Drive partioning. Our servers are now coming with four hot swappable disks. The big picture is:
+  * One approximately 512MB partition on all four disks: configured as RAID1, used as boot partition
+        * The rest of the space on each disk: configured as RAID10, used as encrypted disk
+        * Encrypted disk: used as physical volume for LVM
+        * Create on volume group: vg_${server_name}0
+        * Create standard partitions as logical volume
+ * Details...
+  Since we are using disks at are 2TB or bigger, we need to ensure that the partitions are created properly. Open a new ssh session and choose to switch to console.
