AWS Storage Gateway - Managing Local Disks; Deciding the Amount of Local Disk Storage

AWS Storage Gateway User Guide
Managing Local Disks
While the gateway is stopping, you might see a message that indicates the status of the gateway.
When the gateway shuts down, a message and a Start gateway button appears in the Details tab.
When you stop your gateway, the storage resources will not be accessible until you start your storage.
If the gateway was uploading data when it was stopped, the upload will resume when you start the
gateway.
To start a volume or tape gateway
1. Open the AWS Storage Gateway console at https://console.amazonaws.cn/storagegateway/home.
2. In the navigation pane, choose Gateways and then choose the gateway to start. The status of the
gateway is Shutdown.
3. Choose Details. and then choose Start gateway.
Managing Local Disks for Your AWS Storage
Gateway
The gateway virtual machine (VM) uses the local disks that you allocate on-premises for buffering and
storage. Gateways created on Amazon EC2 instances use Amazon EBS volumes as local disks.

• Determining the Size of Upload Buffer to Allocate (p. 221)
• Determining the Size of Cache Storage to Allocate (p. 222)
• Adding an Upload Buffer or Cache Storage (p. 223)
• Using Ephemeral Storage With EC2 Gateways (p. 223)
Deciding the Amount of Local Disk Storage
The number and size of disks that you want to allocate for your gateway is up to you. Depending on the
storage solution you deploy (see Plan Your Storage Gateway Deployment (p. 8)), the gateway requires
the following additional storage:
• File gateways require at least one disk to use as a cache.
• Volume gateways:
• Stored gateways require at least one disk to use as an upload buffer.
• Cached gateways require at least two disks. One to use as a cache, and one to use as an upload
buffer.
• Tape gateways require at least two disks. One to use as a cache, and one to use as an upload buffer.
The following table recommends sizes for local disk storage for your deployed gateway. You can add
more local storage later after you set up the gateway, and as your workload demands increase.
