How to use Enterprise Instances

Reviewed on 26 May 2021Published on 26 May 2021

This page gathers information about the creation, management and specificities of Scaleway Enterprise Instances. Enterprise Instances are high-end instances based on the AMD EPYC™ 7003 Series Processor. These Instances support the boot-on-block feature which allows them to boot from attached Block Storage volumes. lock Storage is fully backed by SSDs and comes with guaranteed IOPS for critical applications. All data on the Block Storage platform is replicated three times to ensure integrity. Your data is highly available and remains accessible even in case of a disk failure.

Enterprise Instances come without local storage and you can add one or several Block Storage volumes depending on your requirements. The minimum size of a Block Storage volume is 10GB.

Requirements:

How to create an Enterprise Instance

Follow the instructions for creating an Instance, ensuring you conform to the following:

  • Select Paris 2 or Paris 3 as your Availability Zone.

  • Select one of these Images, which are compatible with Enterprise Instances:

    • Ubuntu: Focal, Bionic, Xenial

    • Debian Buster

    • CentOS 8

    • Fedora 32

    • My images: You can populate your own list of instance templates, created from a backup image of an existing Enterprise Instance.

    • Snapshots: You can recover an Enterprise instance from a snapshot of a previously saved block volume containing a compatible boot image.

      Note:

      Enterprise Instances are not compatible with:

  • Select an Enterprise Instance as your Instance Type

  • When configuring your Block Storage volumes, bear in mind the following:

    • You can attach one or several volumes to your instance, depending on your requirements.
    • The minumum size for a Block Storage volume is 10 GB.
    • If several Block Storage volumes are connected to an Enterprise Instance, the first volume will contain the OS and is required to boot the instance. You should not detach this first volume from your Instance in the future, to avoid any issues.

How to connect to an Enterprise Instance

Follow the instructions for connecting to an Instance

How to back up an Enterprise Instance

Follow the instructions for backing up data with Snapshots

Note:

Snapshots created from a local volume (l_ssd) can not be used to create an Enterprise Instance, as it only supports booting from block volume (b_ssd).

How to use Secure Encrypted Virtualization (SEV)

Enterprise Instances rely on the AMD EPYC™ 7003 series Processor, which provides the SEV feature. AMD SEV helps keep your Instance’s data confidential, by encrypting the memory of the virtual machine. SEV doesn’t require any changes to your application software, it is enabled in the hypervisor and in the image of the Enterprise Instance. More details on the SEV feature are available at the AMD website.

You can check that SEV is activated on your Enterprise Instance by entering the following into its command line::

# dmesg | grep -i sev
Note:
  • As the encryption is activated at the boot of the Instance, the boot time can take few seconds more on larger Enterprise instances.
  • If the instance is booted into Rescue Mode, SEV is disabled automatically.
