    3939 * When prompted for component to use, include all of them to be safe (but be sure to include the SSH server one)
    4040 * When given the option - choose to continue your installation via ssh - this will give you the ability to easily set and record pass phrases
    41  * Drive partioning. If you are using 2TB disks or greater... Open a new ssh session and choose to switch to console.
     41 * Drive partioning. Our servers are now coming with four hot swappable disks. The big picture is:
     42  * One approximately 512MB partition on all four disks: configured as RAID1, used as boot partition
     43        * The rest of the space on each disk: configured as RAID10, used as encrypted disk
     44        * Encrypted disk: used as physical volume for LVM
     45        * Create on volume group: vg_${server_name}0
     46        * Create standard partitions as logical volume
     47 * Details...
     48  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.
