![]() For Amazon Linux instances, install the util-linux package using the yum install command. If the lsblk command isn't present, then install the util-linux package from the package management tools for your Linux distribution. Then, retrieve the block device mapping section from the instance metadata. dev/nvme1n1 AWS1A4FC25FB16B79F76 Amazon EC2 NVMe Instance Storage 1 50.00 GB / 50.00 GB 512 B + 0 B 0įor HDD or SSD instance store volumes, get the list of attached block devices from the operating system. Node SN Model Namespace Usage Format FW Rev The example output is from an instance type that supports one NVMe SSD device: $ sudo nvme list The Model column in this output example lists if each attached device is Amazon Elastic Block Store or Amazon EC2 NVMe Instance Storage. Run the nvme list command as a privileged user: $ sudo nvme list For download and installation instructions for other distributions, see the GitHub documentation for nvme-cli, or see the documentation for your distribution. For Amazon Linux instances, use the yum command to install the nvme-cli package. Use the package management tools for your Linux distribution. Install the NVMe command line package, nvme-cli. The identification method depends on whether you have NVMe SSD or HDD/SSD instance store volumes. Determine which of your instance's attached volumes are instance store volumes.Check the quantity, size, type, and performance optimizations of instance store volumes that are available for each supported instance type. Verify the type of instance store volume (HDD, SSD, or NVMe SSD), if any, that your instance supports. ![]() After that, review the volume's information from the operating system (OS). ![]() If the instance supports instance store volumes, then check the type of instance store volumes that it supports. To identify instance store volumes on Amazon EC2 Linux instances, first check if the instance type supports instance store volumes.
