Thank you Russ,

I suppose we could mount a partition from iSCSI storage to AFS file server for futher export to AFS clients.

Is there a way to mount same partition from iSCSI storage across multiple load balanced AFS file servers?

Is there a performance chart for AFS? We are currently able to get ~ 80MB/s transfer rate on a Gbit network if node is directly attached to iSCSI storage.
What kind of data transfer can we expect on an AFS client accessing data via AFS File server using similiar Gbit enviroment?

Thank you.
