Step 1: Create your cache - Amazon File Cache

Step 1: Create your cache

Next, you create your cache. For this exercise, there are instructions about creating a data repository association to link to an Amazon S3 bucket when you create the File Cache.

  1. Open the AWS Management Console at

  2. Choose Caches in the navigation pane.

  3. On the dashboard, choose Create cache to start the cache creation wizard.

    Begin your configuration with the Cache details section.

    The Cache details screen, where you can enter cache parameters.
  4. For Cache name, enter a name for your cache. We recommend using a name that helps you to identify and manage the cache in the future. You can use a maximum of 256 Unicode letters, white spaces, numbers, and these special characters: + - = . _ : /

  5. For Cache storage capacity, set the amount of storage capacity for your cache, in TiB. Set this to a value of 1.2 TiB, 2.4 TiB, or increments of 2.4 TiB.

    Additionally, metadata storage capacity of 2.4 TiB is provisioned for all caches.

  6. The amount of Throughput capacity is calculated by multiplying the cache storage capacity by the throughput tier. For example, for a 1.2 TiB cache, it's 1200 MB/s; for a 9.6 TiB cache, it's 9600 MB/s.

    Throughput capacity is the sustained speed at which the file server that hosts your cache can serve data.

  7. In the Network & security section, provide networking and security group information:

    • For Virtual Private Cloud (VPC), choose the Amazon VPC that you want to associate with your cache.

    • For VPC Security Groups, the ID for the default security group for your VPC should already be added.

    • For Subnet, choose any value from the list of available subnets.

  8. In the Encryption section, for Encryption key, choose the AWS Key Management Service (AWS KMS) encryption key that protects your cache's data at rest.

  9. For Tags - optional, you can enter a key and value to add tags to your cache. A tag is a case-sensitive key-value pair that helps you to manage, filter, and search for your cache.

  10. Choose Next.

  11. In the Data repository associations (DRAs) section, there are no DRAs linking your cache to Amazon S3 or NFS data repositories. For detailed information about linking data repositories to Amazon File Cache, see To link an S3 bucket or NFS file system while creating a cache (console).

    The following instructions describe how to link your cache to an existing Amazon S3 bucket for this getting started exercise. In the Data repository association dialog box, provide information for the following fields.

    1. For Repository type, choose S3.

    2. For Data repository path, enter the path of the existing S3 bucket or prefix to associate with your cache (for example, s3://my-bucket/my-prefix/).

    3. For Cache path, enter the name of a high-level directory (such as /ns1) or subdirectory (such as /ns1/subdir) within Amazon File Cache to associate with the S3 data repository. The first forward slash in the path is required.


      Cache path can only be set to root (/) on NFS DRAs when Subdirectories is specified. If you specify root (/) as the Cache path, you can create only one DRA on the cache.

      Cache path can't be set to root (/) for an S3 DRA.

    4. Choose Add.

  12. Choose Next.

  13. Review the cache configuration shown on the Cache summary page. For your reference, note which cache settings you can modify after the cache is created.

  14. Choose Create cache.

Now that you've created your cache, note its fully qualified domain name and mount name for a later step. You can find the fully qualified domain name and mount name for a cache by choosing the name of the cache in the Caches dashboard, and then choosing Attach.
