By default, transfer resources are shared between all VJBOD Cloud volumes and LUNs. When a volume or LUN needs to upload to or download data from the cloud, VJBOD Cloud removes transfer resources from the shared transfer resource pool and temporarily allocates them to the volume or LUN, then returns them to the pool after the data transfer has finished.
A single volume or LUN may use a large number of shared transfer resources, stopping other volumes and LUNs from syncing data with the cloud. To prevent this you can reserve transfer resources for a volume or LUN, guaranteeing that those resources will always be available. You can also set a limit on the maximum number of transfer resources a volume or LUN can use.
