If you really mean geographic redundancy, then I do hope you have some real nice fat low-latency pipes between those 2 data centers, otherwise _any_ solution involving synchronous replication is just going to make your users real unhappy. > Are > the clients that do some transaction to my website will be affected because > heavy traffic cause by drbd real time replication? You mean will DRBD replication/resync bite a major chunk off your web application's performance? If you configure DRBD and MySQL correctly, no. You might want to have a chat with a MySQL Professional Services consultant on that matter. DRBD is a fully supported MySQL Enterprise add on. See http://www.mysql.com/drbd.
