LockBox storage is a service provided on Bare Metal Servers provisioned prior to 11/13/2013. For each Bare Metal Server ordered, 1GB of LockBox storage is included. LockBox is primarily used by customers to store ISOs to install Operating Systems that we currently don't offer and runs on the same host systems as our NAS service. For additional storage similar to LockBox past the 1GB limit, Network Attached Storage (NAS) can be ordered at any time.
