Edge Bare Metal support: Drive layout

Learn how storage is delivered to Lumen^® Edge Bare Metal servers provisioned for your organization. When deployed, only the boot drive is formatted and configured with the installed operating system. The remaining drives are available to use for your needs.

The Defense Information Systems Agency Security Technical Implementation Guide (DISA STIG) provides strong recommendations about specific ways to make server divisions and which options should be applied to specific directories. By providing the system configured with Logical Volume Manager (LVM), you can implement the requirements of this standard.

This provides the choice to use any filesystem supported by the operating system you select. For Linux systems, that is typically a combination of ext{2,3,4}, xfs, btrfs, or zfs.

Lumen places no limitations on your filesystem choice. The precise amount of disk space in any given initial partition is subject to change.

The boot drive for Linux operating systems is configured as follows:

1. /boot/efi a FAT32 partition used for booting the operating system. In deployments, this is typically 536MiB (mebibytes).
2. The remaining disk is configured to use LVM. This allows post deployment configuration, including adding storage from other available local disks, as needed.
3. A small OS root mounted at / to provide the initial area for the installed operating system. (DISA STIG)
4. The remaining 180GiB (gibibyte, approximately) is used for post-deployment user configuration.
