Configuring additional cache storage

As your application needs change, you can increase the gateway's cache storage capacity. You can add storage capacity to your gateway without interrupting functionality or causing downtime. When you add more storage, you do so with the gateway VM turned on.

Important

When adding cache to an existing gateway, you must create new disks on the gateway host hypervisor or Amazon EC2 instance. Do not remove or change the size of existing disks that have already been allocated as cache.

To configure additional cache storage for your gateway

1. Provision one or more new disks on your gateway host hypervisor or Amazon EC2 instance. For information about how to provision a disk on a hypervisor, see your hypervisor's documentation. For information about provisioning Amazon EBS volumes for an Amazon EC2 instance, see Amazon EBS volumes in the Amazon Elastic Compute Cloud User Guide for Linux Instances. In the following steps, you will configure this disk as cache storage.

2. Open the Storage Gateway console at https://console.aws.amazon.com/storagegateway/home.

3. In the navigation pane, choose Gateways.

4. Search for your gateway and select it from the list.

5. From the Actions menu, choose Configure cache storage.

6. In the Configure cache storage section, identify the disks you provisioned. If you don't see your disks, choose the refresh icon to refresh the list. For each disk, choose Cache from the Allocated to drop-down menu.

   Note

   Cache is the only available option for allocating disks on a File Gateway.

7. Choose Save changes to save your configuration settings.
