AWS Storage Gateway User Guide
Network and Firewall Requirements
If you have more than 5 million objects in your Amazon S3 bucket and you are using a General
Purposes SSD volume, a minimum root EBS volume of 350 GiB is needed for acceptable
performance of your gateway during start up. For information about how to increase your

Recommended for cached volumes and tape gateway types
• General-purpose instance family—m4 or m5 instance types. We don't recommend using the
m4.16xlarge
instance type.
• Compute-optimized instance family—c4 or c5 instance types. Select the
2xlarge
instance size or
higher to meet the required RAM requirements.
• Storage-optimized instance family—d2, i2, or i3 instance types
Note
When you create any gateway type using the c4 or m4 instance type, it can't be changed to the
c5 or m5 instance type. For information about how to upgrade your instance to the c5 or m5
instance type, see

Storage Requirements
In addition to 80 GiB disk space for the VM, you also need additional disks for your gateway.

Note
You can configure one or more local drives for your cache and upload buffer, up to the
maximum capacity.
When adding cache or upload buffer to an existing gateway, it's important 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.

Network and Firewall Requirements
Your gateway requires access to the internet, local networks, Domain Name Service (DNS) servers,
firewalls, routers, and so on. Following, you can find information about required ports and how to allow
access through firewalls and routers.
