Hello Everyone,
I'm a newbie to MySQL but have a good knowledge and understanding of Oracle RAC. I'm asked to setup MySQL Cluster for an application with read vs. write ratio of 80:20. Set-up should be highly available and read intensive.
We have the commercial version of mysql cluster with 6 data nodes, planning to setup in 2 node groups with 3 replicas for higher redundancy and 2 Mysql nodes which will house the management nodes as well. Each data nodes comes with 96G memory and storage for all data nodes comes from SAN with 96 disks mounted via FC. We haven't done any RAID yet though it is obvious to setup RAID 1+0 but wanted to get some help and not overlook some thing very obvious.
I have already read the Evaluation Guide for 7.2GA release, in that High-End setup for disk based tables meets our setup, as we plan on housing table in both memory and disk.
As per the evaluation guide, i see mysql has recommended to house undolog, redolog/LCP, tablespaces(n) all in separate RAID sets. With 96 SAS 15K RPM disks available in Storage, I'm leaning towards creating following raid sets. Any comments or improvements is appreciated.
1. Undolog - 6+6 RAID 1+0
2. Redolog/LCP - 6+6 RAID 1+0
3. Tablespace1 - 6+6 RAID 1+0, x 6 (one raid set for each data node)
