# Configuring Google Managed Lustre

> Source: https://parallelworks.com/docs/storage/configuring-lustre/google-managed-lustre

The configuration parameters on this page are exclusive to Google Managed Lustre.

Google Managed Lustre is always persistent storage, so you won't be asked to choose between **Ephemeral** and **Persistent** when you create it. After you create the storage, start it with the power button to provision the filesystem.

Please note that Google Managed Lustre measures storage in tebibytes (TiB); a tebibyte is equivalent to 1,099,511,627,776 bytes, or 1.1 terabytes (TB).

#### Region

Use this dropdown menu to select the region where your storage will be created. A region represents a geographic area.

Only regions in which a network has been provisioned are listed here. Contact your organization administrator to provision a network in additional regions.

#### Zone

Use this dropdown menu to select the zone to create the filesystem in. A zone refers to an isolated location inside a region.

We recommend that your storage zone matches the zone of the cluster you're pairing the storage with.

#### Performance

Use this dropdown menu to select the throughput of your filesystem. Throughput is measured in megabytes (MB) per second, per tebibyte (TiB) of storage. The options are `125 MBps/TiB`, `250 MBps/TiB`, `500 MBps/TiB`, and `1,000 MBps/TiB`.

The **Performance** you select determines the minimum, maximum, and increments of **Capacity in TiB**. Higher performance tiers allow smaller filesystems.

For more information about performance tiers, please see [the Google Cloud documentation](https://cloud.google.com/managed-lustre/docs/performance).

#### Capacity in TiB

Use this field and slider to select the size of your filesystem in TiB. The available range depends on the **Performance** you selected:

| Performance | Minimum | Maximum | Increment |
| --- | --- | --- | --- |
| 125 MBps/TiB | 72 TiB | 7,632 TiB | 72 TiB |
| 250 MBps/TiB | 36 TiB | 3,816 TiB | 36 TiB |
| 500 MBps/TiB | 18 TiB | 1,908 TiB | 18 TiB |
| 1,000 MBps/TiB | 9 TiB | 954 TiB | 9 TiB |

Please note that altering the capacity or performance will affect your estimated hourly cost.

:::note
**Region**, **Zone**, **Performance**, and **Capacity in TiB** cannot be changed while the filesystem is running. To change them, stop the storage first.
