HI, I will enable users to check and let MFNetDisk verify if the PC is totally synchronize with the real disk 3390 by checking if pending tracks in MF and PC to be synchronize. I will support new compressed MFNetDisk 3390 disk format in open systems. This new format will not reduce the IO performance compare to what is now. I will enable to create unlimited snapshot disks mirrors in a very compressed PC disk space. Meaning sending snapshot command from MF with create snapshot of the 3390, MFNetDisk will keep the mirror activity but create new mirror only with the changed cylinders. Users can define generation to keep (unlimited). Much work need to be done to make these work but soon it will be implemented in my code.
I already wrote feature which enable the user for some special read CCW chain to make prefetch to the track to not efficient CCW (one disk read for each CCW). This will eliminate the need to send IO to PC. Still the default will be non prefetch track, but by doing modify command with PRF=Y, MFNetDisk will use this feature. Also, soon more use of processing MF DSN from PC without accessing the MF will be used for processing SMF records. This will be implement for user request. this is currently the last request in my list.
