    Tape Migration time

    User 12587430-Oracle

      Hi experts,

      I try to estimate how long to migrate data according the three options available in OHSM.


      With disk buffer: time to read the old format, write to disk and write to the new format, roughly I add the two following periods: tape reading and tape writing.


      With buffered copy: I don't know how the OHSM server handles the data between read and write operations, are they sequential or concurrent operations ?

      In other words the consumed time is roughly the time to read (old format) and write (new format) or only read (old format)?


      With direct copy: I assume that only the time to read (old format) may be considered.


      Thanks for your advices.
