Metadata storage
By default, the B2B Gateway use metadata storage to persist transaction metadata on the unencrypted partition on the RAID volume.
The B2B persistence configuration can be accessed by administrators in the
default
domain. The default size for metadata storage is 1 GB to allow other uses
of the RAID volume. For a virtual DataPower® Gateway with B2B storage enabled,
the size of metadata storage must not exceed half of the entire RAID volume. For other DataPower Gateway models, the size can be safely increased to 64 GB.
The initial firmware setup does not use the RAID volume for anything besides metadata and document storage for B2B transactions.
