HI, I decide that now is the time to give push to the replication feature of MFNetDisk.
New fix for the replication. This fix make the process of all CCWS chain easier and more reliable. overhead for the process of CCWS chain is now much better for read chain CCWS. The fix also fixes some bugs processing non standard CCWS including search key CCWS and SHARK CCWS and many more. The process to fix CCWS chains in now much more easy. I create advance tests which enable me to create many random CCWS chain automatically and analize the result in user mode and not in disable mode as it was in the past. As I said before it is now time to start and try this important feature in MFNetDisk. As I mention before the replication overhead is almost zero. The real disk which is the source disk is read only to MFNetDisk. MFnetDisk never delay the IO operation for the real disk. Also, you can freeze mirror at Sync point. You can avoid communicate with the PC during rush hour for the real disk and you can ReSync the mirrors at any time you like without losing any tracks to be ReSync. In this case only the changes tracks will be ReSync. That can be good tool to backup in short time many many real disks (IBM, EMC and HDS). If you only use the emulation of disks and tapes then this fix can be skipped.
