When a user uploads an ISO/OVF/OVA from their desktop to VCF Automation (VCFA) Content Library, the file is temporarily stored in the Transfer Spooling Area (TSA) that resides locally within VCFA before it is finally transferred to the destination vCenter Server.

By default, VCFA uses an embedded object store backed by SeaweedFS to hold the temporary user files, which are stored in 64MB chunks. The size of the SeaweedFS volumes will be based on the VCFA deployment mode (single node vs multi-node for HA). A total of three volumes (3 replicas) will always be configured regardless of the deployment mode for VCFA and the total usable storage capacity is sum of these three volumes.
- Single Node, each volume is 75GB
- Multi-Node (Medium), each volume is 150GB
- Multi-Node (Large), each volume is 200GB
