Can someone help out this questioner? I know zip about Cluster. I looked at the FAQ for a bit and thought that what he wants is probably doable, but I couldn't tell if it would be easy or painful to do load-balancing in this particular way. (And I'm not qualified to say if what he wants is a sensible approach, either.) regards, tom lane ------- Forwarded Message Date: Sat, 24 Feb 2007 15:37:17 +0000 From: Ivan Zoratti <ivan@xxxxxxxxx> To: tgl@xxxxxxxxxx Subject: Question on RH Cluster from a MySQL Customer Dear Tom, first of all, let me introduce myself. I am the Sales Engineering Manager for EMEA at MySQL. Kath O'Neil, our Director of Strategic Alliances, kindly gave me your name for a technical question related to the use of Red Hat and MySQL - hopefully leading to the adoption of RH Cluster. Our customer is looking for a solution that could provide high availability and scalability in a cluster environment based on linux servers that are connected to a large SAN. Their favourite choice would be to go with Red Hat. Each server connected to the SAN would provide resources to host, let's say, 5 different instances of MySQL (mysqld). Each mysqld will have its own configuration, datadir, connection port and IP address. The clustering software should be able to load-balance new mysqld instances on the available servers. For example, considering servers with same specs and workload, when the first mysqld starts, it will be placed on Server A, the second one will go on Server B and so on for C,D and E. The sixth mysqld will then go on A again, then B and so forth. If one of the server fails, the mysqld(s) is (or are) "moved" on the other servers, still in a way to guarantee a load- balance of the whole system. After my long (and hopefully clear enough) explanation, my quick question is: does RH Cluster provide this kind of features? I am mostly interested in the way we can instatiate mysqld and re-launch them on any other server in the cluster in case of fault. I would be very grateful if you could help me or address me to somebody or something for an answer. Thank you in advance for your help.
