Nobus FBS volumes are launched in a particular Availability Zone and can be from 1 GB to 16 TB in size. Once a volume is launched, it can be attached to any Nobus FCS instance in the same Availability Zone. Once attached, it will appear as a mounted device similar to any hard drive or other block device. At that point, the instance can interact with the volume just as it would with a local drive, formatting it with a file system or installing applications on it directly.
