AWS Storage Gateway User Guide
Supported iSCSI Initiators
through optimized transfers. Reads are first served through the local cache. If data is not available, it's
fetched through Amazon S3 as a read-through cache.
Writes and reads are optimized in that only the parts that are changed or requested are transferred
through your gateway. Deletes remove objects from S3. Directories are managed as folder objects in S3,
using the same syntax as in the Amazon S3 Management Console.
HTTP operations such as
GET
,
PUT
,
UPDATE
, and
DELETE
can modify files in a file share. These
operations conform to the atomic create, read, update, and delete (CRUD) functions.
Supported iSCSI Initiators
When you deploy a cached volume or stored volume gateway, you can create iSCSI storage volumes on
your gateway. When you deploy a tape gateway, the gateway is preconfigured with one media changer
and 10 tape drives. These tape drives and the media changer are available to your existing client backup
applications as iSCSI devices.
To connect to these iSCSI devices, AWS Storage Gateway supports the following iSCSI initiators:
• Windows Server 2012 and Windows Server 2012 R2
• Windows Server 2008 and Windows Server 2008 R2
• Windows 7
• Red Hat Enterprise Linux 5
• Red Hat Enterprise Linux 6
• Red Hat Enterprise Linux 7
• VMware ESX Initiator, which provides an alternative to using initiators in the guest operating systems
of your VMs
Important
Storage Gateway doesn't support Microsoft Multipath I/O (MPIO) from Windows clients.
Storage Gateway supports connecting multiple hosts to the same volume if the hosts coordinate
access by using Windows Server Failover Clustering (WSFC). However, you can't connect multiple
hosts to that same volume (for example, sharing a nonclustered NTFS/ext4 file system) without
using WSFC.
Supported Third-Party Backup Applications for a
Tape Gateway
You use a backup application to read, write, and manage tapes with a tape gateway. The following third-
party backup applications are supported to work with tape gateways.
The type of medium changer you choose depends on the backup application you plan to use. The
following table lists third-party backup applications that have been tested and found to be compatible
with tape gateways. This table includes the medium changer type recommended for each backup
application.
