2 TiB

Stored volume gateway 150 GiB

2 TiB

1 or more for stored volume or volumes
Tape gateway 150 GiB 64 TiB 150 GiB 2 TiB
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.
