Managing Your Volume Gateway
Managing Your Volume Gateway
Following, you can find information about how to manage your volume gateway resources.
Cached volumes are volumes in Amazon Simple Storage Service (Amazon S3) that are exposed as iSCSI
targets on which you can store your application data. You can find information following about how
to add and delete volumes for your cached setup. You can also learn how to add and remove Amazon
Elastic Block Store (Amazon EBS) volumes in Amazon EC2 gateways.

Important
If a cached volume keeps your primary data in Amazon S3, you should avoid processes that
read or write all data on the entire volume. For example, we don't recommend using virus-
scanning software that scans the entire cached volume. Such a scan, whether done on demand
or scheduled, causes all data stored in Amazon S3 to be downloaded locally for scanning, which
results in high bandwidth usage. Instead of doing a full disk scan, you can use real-time virus
scanning—that is, scanning data as it is read from or written to the cached volume.
Resizing a volume is not supported. To change the size of a volume, create a snapshot of the volume, and
then create a new cached volume from the snapshot. The new volume can be bigger than the volume
from which the snapshot was created. For steps describing how to remove a volume, see
. For steps describing how to add a volume and preserve existing data, see
All cached volume data and snapshot data is stored in Amazon S3 and is encrypted at rest using server-
side encryption (SSE). However, you cannot access this data by using the Amazon S3 API or other tools
such as the Amazon S3 Management Console.
Adding a Volume
As your application needs grow, you might need to add more volumes to your gateway. As you add
more volumes, you must consider the size of the cache storage and upload buffer you allocated to
the gateway. The gateway must have sufficient buffer and cache space for new volumes. For more
information, see
Determining the Size of Upload Buffer to Allocate (p. 221)
You can add volumes using the AWS Storage Gateway console or AWS Storage Gateway API. For
information on using the AWS Storage Gateway API to add volumes, see
