Creating a Gateway - AWS Storage Gateway

Creating a Gateway

In this section, you can find instructions about how to download, deploy, and activate a volume gateway.

Choosing a Gateway Type

With a volume gateway, you can create storage volumes in the Amazon Web Services Cloud that your on-premises applications can access as Internet Small Computer System Interface (iSCSI) targets. There are two options:

  • Cached volumes—Store your data in AWS and retain a copy of frequently accessed data subsets locally.

  • Stored volumes —Store all your data locally and asynchronously back up point-in-time snapshots to AWS.

To choose a gateway type

  1. Open the Amazon Web Services Management Console at https://console.aws.amazon.com/storagegateway/home, and choose the AWS Region that you want to create your gateway in.

    If you have previously created a gateway in this AWS Region, the console shows your gateway. Otherwise, the service homepage appears.

  2. If you haven't created a gateway in the AWS Region you selected, choose Get started. If you already have a gateway in the AWS Region you chose, choose Gateways from the navigation pane, and then choose Create gateway.

  3. On the Select gateway type page, choose Volume gateway, choose the type of volume, and then choose Next.

Choosing a Host Platform and Downloading the VM

If you create your gateway on-premises, you deploy the hardware appliance, or download and deploy a gateway VM, and then activate the gateway. If you create your gateway on an Amazon EC2 instance, you launch an Amazon Machine Image (AMI) that contains the gateway VM image and then activate the gateway. For information about supported host platforms, see Supported hypervisors and host requirements.

Note

You can run only file, cached volume, and tape gateways on an Amazon EC2 instance.

To choose a host platform and download the VM

  1. For Select host platform, choose the virtualization platform that you want to run your gateway on.

  2. Do one of the following:

    • If you choose the hardware appliance, activate it by following the instructions in Activating your hardware appliance.

    • If you choose one of the other options, choose Download image next to your virtualization platform to download a .zip file that contains the .ova file for your virtualization platform.

      Note

      The .zip file is over 500 MB in size and might take some time to download, depending on your network connection.

      For Amazon EC2, you create an instance from the provided AMI.

  3. If you choose a hypervisor option, deploy the downloaded image to your hypervisor. Add at least one local disk for your cache and one local disk for your upload buffer during the deployment. A file gateway requires only one local disk for a cache. For information about local disk requirements, see Hardware and storage requirements.

    Depending your hypervisor, set certain options:

    • If you choose VMware, do the following:

      • Store your disk using the Thick provisioned format option. When you use thick provisioning, the disk storage is allocated immediately, resulting in better performance. In contrast, thin provisioning allocates storage on demand. On-demand allocation can affect the normal functioning of Storage Gateway. For Storage Gateway to function properly, the VM disks must be stored in thick-provisioned format.

      • Configure your gateway VM to use paravirtualized disk controllers. For more information, see Configuring the AWS Storage Gateway VM to Use Paravirtualized Disk Controllers.

    • If you choose Microsoft Hyper-V, do the following:

      • Configure the disk type using the Fixed size option. When you use fixed-size provisioning, the disk storage is allocated immediately, resulting in better performance. If you don't use fixed-size provisioning, the storage is allocated on demand. On-demand allocation can affect the functioning of Storage Gateway. For Storage Gateway to function properly, the VM disks must be stored in fixed-size provisioned format.

      • When allocating disks, choose virtual hard disk (.vhd) file. Storage Gateway supports the .vhdx file type. By using this file type, you can create larger virtual disks than with other file types. If you create a .vhdx type virtual disk, make sure that the size of the virtual disks that you create doesn't exceed the recommended disk size for your gateway.

    • If you choose Linux Kernel-bases Virtual Machine (KVM), do the following:

      • Don't configure your disk to use sparse formatting. When you use fixed-size (nonsparse) provisioning, the disk storage is allocated immediately, resulting in better performance.

      • Use the parameter sparse=false to store your disk in nonsparse format when creating new virtual disks in the VM with the virt-install command for provisioning new virtual machines.

      • Use virtio drivers for disk and network devices.

      • We recommend that you don't set the current_memory option. If necessary, set it equal to the RAM provisioned to the gateway in the --ram parameter.

      Following is an example virt-install command for installing KVM.

      virt-install --name "SGW_KVM" --description "SGW KVM" --os-type=generic --ram=32768 --vcpus=16 --disk path=fgw-kvm.qcow2,bus=virtio,size=80,sparse=false --disk path=fgw-kvm-cache.qcow2,bus=virtio,size=1024,sparse=false --network default,model=virtio --graphics none --import
Note

For VMware, Microsoft Hyper-V, and KVM, synchronizing the VM time with the host time is required for successful gateway activation. Make sure that your host clock is set to the correct time and synchronize it with a Network Time Protocol (NTP) server.

For information about deploying your gateway to an Amazon EC2 host, see Deploy Your Gateway to an Amazon EC2 Host.

Choosing a Service Endpoint

You can activate your gateway using:

  • A public service endpoint and have your gateway communicate with AWS storage services over the public internet.

  • A Federal Information Processing Standards (FIPS) compliant public service endpoint and have your gateway communicate with AWS storage services over the public internet.

  • A public service endpoint and have your gateway communicate with AWS storage services using a virtual private cloud (VPC) endpoint, which is private.

Note

If you use a VPC endpoint, all VPC endpoint communication from your gateway to AWS services occurs through the public service endpoint using your VPC in AWS.

New Console

To choose a service endpoint

  1. For Select service endpoint, choose one of the following:

    • To have your gateway access AWS services over the public internet using a public service endpoint, choose Public.

    • To have your gateway access AWS services over the public internet using a public service endpoint that complies with FIPS, choose FIPS.

      If you require FIPS 140-2 validated cryptographic modules when accessing AWS through a command line interface or an API, use a FIPS endpoint. For more information about the available FIPS endpoints, see Federal Information Processing Standard (FIPS) 140-2.

    • To have your gateway access AWS services over a private VPC endpoint connection using a public service endpoint, choose VPC.

    Note

    The FIPS service endpoint is only available in some AWS Regions. For more information, see Storage Gateway endpoints and quotas in the AWS General Reference.

    This procedure assumes that you are activating your gateway with a public endpoint. For information about how to activate a gateway using a VPC endpoint, see Activating a gateway in a virtual private cloud.

Connecting to Your Gateway

To connect to your gateway, first get the IP address or activation key of your gateway VM. You use the IP address or activation key to activate your gateway. For gateways deployed and activated on an on-premises host, you can get the IP address or activation key from your gateway VM local console or your hypervisor client. For gateways deployed and activated on an Amazon EC2 instance, you can get the IP address or activation key from the Amazon EC2 console.

The activation process associates your gateway with your AWS account. Your gateway VM must be running for activation to succeed.

Note

Make sure that you select the correct gateway type. The .ova files and Amazon Machine Images (AMIs) for the gateway types are different and are not interchangeable.

To get the IP address or activation key for your gateway VM from the local console

  1. Log on to your gateway VM local console. For detailed instructions, see the following:

  2. Get the IP address from the top of the menu page, and note it for later use.

To get the IP address or activation key from an EC2 instance

  1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

  2. In the navigation pane, choose Instances, and then choose the EC2 instance.

  3. Choose the Details tab at the bottom, and then note the IP address or activation key. You use one of these to activate the gateway.

Note

For activation with an IP address, you can use the public or private IP address assigned to a gateway. You must be able to reach the IP address that you use from the browser from which you perform the activation.

Configuring Local Disks

When you deployed the VM, you allocated local disks for your gateway. Now you configure your gateway to use these disks.

Note

If you allocate local disks on a VMware host, make sure to configure the disks to use paravirtualized disk controllers.

When adding a cache or upload buffer to an existing gateway, make sure to create new disks in your host (hypervisor or Amazon EC2 instance). Don't change the size of existing disks if the disks have been previously allocated as either a cache or upload buffer.

  • For a cached volume, you configure at least one disk for an upload buffer and the other for cache storage.

  • For a stored volume, you configure at least one disk for an upload buffer and allocate the rest of the storage for your application data.

To configure local disks

  1. For Configure local disks, identify the disks you allocated and decide which ones you want to use for an upload buffer and cached storage. For information about disk size quotas, see Recommended local disk sizes for your gateway.

  2. For Allocated to, choose Upload buffer for the disk you want to configure as upload buffer.

  3. For cached volumes and tapes, choose Cache for the disk you want to configure as cache storage.

    If you don't see your disks, choose Refresh.

  4. Choose Continue to logging.
