AWS NVMe drivers for Windows instances

EBS volumes and instance store volumes are exposed as NVMe block devices on Nitro-based instances. You must have the AWS NVMe driver installed in order to use an NVMe block device. The latest AWS Windows AMIs for Windows Server 2008 R2 and later contain the required AWS NVMe driver.

For more information about EBS and NVMe, see Amazon EBS and NVMe on Windows instances. For more information about SSD instance store and NVMe, see SSD Instance Store Volumes.

Installing or upgrading AWS NVMe drivers

If you are not using the latest AWS Windows AMIs provided by Amazon, use the following procedure to install the current AWS NVMe driver. You should perform this update at a time when it is convenient to reboot your instance. Either the install script will reboot your instance or you must reboot it as the final step.

Prerequisites

PowerShell 3.0 or later

To download and install the latest AWS NVMe driver

1. Connect to your instance and log in as the local administrator.

2. Download and extract the drivers using one of the following options:

   • Using a browser:

     1. Download the latest driver package to the instance.

     2. Extract the zip archive.

   • Using PowerShell:

     invoke-webrequest https://s3.amazonaws.com/ec2-windows-drivers-downloads/NVMe/Latest/AWSNVMe.zip -outfile $env:USERPROFILE\nvme_driver.zip
     expand-archive $env:userprofile\nvme_driver.zip -DestinationPath $env:userprofile\nvme_driver

3. Install the driver by running the install.ps1 PowerShell script. If you get an error, make sure you are using PowerShell 3.0 or later.

4. If the installer does not reboot your instance, reboot the instance.
