I think there may be some confusion here. By HSM I was referring to Hierarchical Storage Management, whereby there are multiple levels of storage (fast+expensive <-> slow+cheap) and files migrate up or down. Originally it was used to keep data on tape with the metadata residing on disk though it has been expanded to allow a SAS/SATA hierarchy. Quite where PKI comes in I'm not sure, unless you are implementing it over an external network.
