Hi,


   For Direct Attached Storage I believe I am correct in saying that
when a transaction is committed it is written to disk.



   For external storage, such as an IBM ESS(Shark) am I correct in
saying that a transactions may be written to the ESS cache and not
written to disk?



   Would this mean a subsequent general power failure could cause
transactions (otherwise supposed to be committed) to be lost?



thanks



Tim
