-Our servers are now coming with four hot swappable disks. 
+Our servers are now coming with four hot swappable disks, 2 SSD and 2 SATA.
 
 === The big picture is ===
+
   * '''All partitions should be Primary'''
-  * 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
+
+The SATA disks:
+
+  * One tiny partition on both disks uses for bios/grub data
+  * A second approximately 512MB partition on both disks: configured as RAID1, used as boot partition
+  * The rest of the space on each SATA disk: configured as RAID1, 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 - Using the Installer or manually via debootstrap ===

-Since we are using disks at are 2TB or bigger, we need to ensure that the partitions are created properly. Also, we leave 100MB at the end in case a replacement disk is a smidge smaller (thanks bug magnet!). Open a new ssh session and choose to switch to console.
