Dear Junzo,

MySQL cluster has native support for SCI our you can use the SCI Socket software. You will find more information about this and some benchmark numbers at http://dev.mysql.com/doc/mysql/en/MySQL_Cluster_Interconnects.html

With SCI Socket, you can configure MySQL cluster for regular networking and just use SCI Socket between the nodes that requires low latency/high bandiwidth connections. SCI Socket has typically 10x lower latency than Gigagit Ethernet and should support any version of MySQL Cluster that runs properly over Ethernet.

You will find the SCI Socket software and more information at http://www.dolphinics.com/products/software/sci_sockets.html

Best regards

Hugo

Hello

Very recently I found sections in the chapter of Cluster, which is decsribing utilization of high-speed interconnection called SCI. I would like to test it. Currently I have totaly 5 servers and 4 out of 5 are equiped with SCI network card. Please anyone provide me any suggestions regarding the following cluster configuration. All server are connected together with Ethernet. Node a1 through a4 are with SCI. I would like to assign mgmd and api(mysqld) to front-end and ndbd for a[1-4]. Is this feasible and reasonable configuration ?

I am using MySQL 4.1.7-gamma as of Oct. 26th, 2004.

Thank you in advance. /Junzo
