Managing local disks for your gateway
The gateway virtual machine (VM) uses the local disks that you allocate on-premises for buffering and storage. A File Gateway that you create on an Amazon EC2 instance will Amazon EBS volumes as local disks. The number and size of disks that you want to allocate for your gateway is up to you. The gateway uses the cache storage that you allocate to provide low-latency access to your recently accessed data. The cache storage acts as the on-premises durable store for data that is pending upload to Amazon FSx. File Gateways require at least one 150 GiB disk to use as a cache. After the initial configuration and deployment of your gateway, you can add more disks for cache storage as your workload demands increase. This section contains the following topics, which describe concepts and procedures related to managing local disks.
