AWS API Changes

2016/12/20 - AWS Storage Gateway - 5 new 5 updated api methods

Changes File gateway is a new mode in the AWS Storage Gateway that support a file interface into S3, alongside the current block-based volume and VTL storage. File gateway combines a service and virtual software appliance, enabling you to store and retrieve objects in Amazon S3 using industry standard file protocols such as NFS. The software appliance, or gateway, is deployed into your on-premises environment as a virtual machine (VM) running on VMware ESXi. The gateway provides access to objects in S3 as files on a Network File System (NFS) mount point.

CreateCachediSCSIVolume (updated)

Link ¶
Changes (request)

{'SourceVolumeARN': 'string'}

Creates a cached volume on a specified cached gateway. This operation is supported only for the gateway-cached volume architecture.

Note

Cache storage must be allocated to the gateway before you can create a cached volume. Use the AddCache operation to add cache storage to a gateway.

In the request, you must specify the gateway, size of the volume in bytes, the iSCSI target name, an IP address on which to expose the target, and a unique client token. In response, AWS Storage Gateway creates the volume and returns information about it. This information includes the volume Amazon Resource Name (ARN), its size, and the iSCSI target ARN that initiators can use to connect to the volume target.

Optionally, you can provide the ARN for an existing volume as the SourceVolumeARN for this cached volume, which creates an exact copy of the existing volume’s latest recovery point. The VolumeSizeInBytes value must be equal to or larger than the size of the copied volume, in bytes.
