Transfer Resources
The
Transfer Resources
screen displays the total number of transfer resources allocated to VJBOD Cloud,
and the number of transfer allocated to each VJBOD Cloud volume and LUN. On this screen you can
manage transfer resources allocation.
Transfer Resource Overview
In VJBOD Cloud, transfer resources correspond to data uploads and downloads. If VJBOD Cloud has 100
total transfer resources, that means the application can create 100 threads for uploading data to and
downloading data from the cloud. The total transfer resources allocated to VJBOD Cloud is determined by
your NAS hardware.
Transfer Resource Allocation
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.
Transfer Resource Usage Guidelines
Problem
Solution
VJBOD Cloud is taking a long time to sync data to
the cloud.
Increase the total number of transfer resources
allocated to VJBOD Cloud.
VJBOD Cloud is using too much NAS memory, CPU,
or network bandwidth.
Decrease the total number of transfer resources
allocated to VJBOD Cloud.
