# Create a disk

Create a disk of the size you choose in your project and region, encrypted if you want.

## Before you begin

- A TIR project in Delhi or Chennai.
- Permission to create datasets in the project. A Member gets it through a policy that allows creating datasets.
- A name in mind, and a size. The form shows the price per GB per month for the size you pick. For
  rates, see [E2E's pricing page](https://www.e2enetworks.com/pricing). For an estimate across
  services, use the [E2E pricing calculator](https://calculator.e2enetworks.com/estimate-pricing).

## Fill in the form

1. In TIR, open your project. In the side menu, under **Storage**, select **Block Storage (Disk
   Dataset)**.
2. Select **Create Dataset**.
3. In **Dataset Name**, keep the generated name, which looks like `tir-dataset-<letters and
digits>`, or type your own. A name is up to 50 characters, uses only lowercase letters,
   numbers, and hyphens, and starts and ends with a letter or number. It must differ from the names of
   the project's other datasets, Shared File Systems, and Parallel File Systems.
   The name becomes the folder the disk appears in on an instance, `/datasets/<name>`, so choose
   one you want to read in a path.
4. (Optional) To encrypt the disk, turn **Enable Encryption** on. **E2E Managed** is the only
   encryption type. Encryption is included in the disk price. Choose now: a disk's
   encryption stays as you set it.
5. Set **Disk Size**, in GB. It starts at 100 GB, and the smallest size is 10 GB. The largest is
   your disk size limit, which is 15,000 GB unless E2E has set a different one for you. To go past
   the limit, see
   [Request a higher disk size limit](/tir/tir-block-storage/how-to/request-a-higher-disk-size-limit/).
   Later you can only make a disk bigger, and you pay for every GB you set, so start close to what
   you need.
6. Check **Total amount chargeable per month**, the cost of the size you picked.
7. Select **Create**.

With encryption on, confirm in **Dataset Encryption** first: tick "I understand that encryption
configuration cannot be changed later" and select **Continue**.

## Check the disk

The disk is created, and **Next Steps: Using Disk Storage** shows how to use it. Close that to return
to the list. The disk is **Pending** until it is ready, then **Ready**. You can mount the disk once it is **Ready**.

You can also create a disk while you create an instance. On the **Create Instance** form, under
**Storage** > **Other storage**, the link to create a new dataset opens this same form. In it,
**Storage Type** offers **EOS BUCKET** or **DISK**, and the disk fields are the same as here.

To use the disk, [mount it on an instance](/tir/tir-block-storage/how-to/mount-a-disk-on-an-instance/).
