+= Server Installation
+
+== Initial steps ==
+
+ * Plug in monitor and keyboard
+ * Boot machine while USB stick is inserted (or while a network cable is plugged directly into the PXE boot machine)
+ * Enter Bios/Setup. Specify that Bios should output to serial console and make our [wiki:bios_changes standard bios changes]
+ * Ensure that server skips errors like no keyboard attached
+ * Reboot and select Boot Options and choose to boot to USB stick (or network)
+ * Choose Expert install
+ * For DNS servers,  use:
+{{{
+Telehouse: 209.51.163.29 209.51.169.83 
+XO: 209.234.253.168
+}}}
+ * 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/Disk setup == 
+
+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.

+
+You should be able to return to the graphical installer to do the rest. 
+
+For the record - here's how you can do it by hand:
+
+RAID:
+
+{{{
+mdadm --create --raid-devices=4 --level=1 --metadata=1.0 --verbose /dev/md0 /dev/sda2 /dev/sdb2 /dev/sdc2 /dev/sdd2
+mdadm --create --raid-devices=4 --level=10 --metadata=1.0 --verbose /dev/md1 /dev/sda3 /dev/sdb3 /dev/sdc3 /dev/sdd3
+}}}
+
+Now cryptsetup:
+
+{{{
+anna-install cryptsetup-udeb
+cryptsetup luksFormat /dev/md1
+cryptsetup luksOpen /dev/md1 md1_crypt
+
+pvcreate /dev/mapper/md1_crypt
+vgcreate vg_nameofserver0 /dev/mapper/md1_crypt
+lvcreate --name swap --size 1GB vg_nameofserver0
+etc.
+}}}
+
+Choose manual partition in the Debian Installer. Then:
+
+ * Choose "Congifure software RAID" (skip step if one disk system)
+  * Choose "Create MD Device"
+  * Choose RAID1
+  * Number of active devices: 4
+  * Number of spare devices: 0
+  * Now select the second partition on each device.
+  * Click Continue. Repeat for third partition on each device but select RAID10 instead of RAID1.
+  * When you are done, click Finish. Now you are back at the partition menu.
+ * Scroll down to the raid devices (or apply straight to your partitions if it's a one disk system). Modify the 512 MB RAID device: Filesystem: ext3, mount on /boot
+ * Encrypt the larger, remaining device. Save passphrase in [wiki:keyringer].
+ * Choose "Congifure LVM" (selecting the device encrypted in the previous step)
+ * Create a volume group called `vg_`''nameofserver''`0`
+ * Create logical volumes in this volume group based on your needs. Suggestions: 3GB for /, 1GB swap.
+
+== Last steps ==
+
+ * After returning to the main disk config menu, click on each logical volume that you create and specify how it should be formatted and mounted.
+ * Enter root password. Save in [wiki:keyringer].
+ * Do not install the server package or the base package - deselect all of them.
