HOST BASED WRITE ORDERING FOR ASYNCHRONOUS REPLICATION
摘要
<p>A host write based write ordering mechanism is used so the write ordering on the secondary system is derived from the write ordering applied by the host to the primary system. In this scheme any set of writes that was issued in parallel on the primary system may also be issued in parallel on the secondary system. The parallel writes provide better performance compared to absolute or strict write ordering allowing only one outstanding write per volume group.</p>
