I have been unable to find information reguarding the pros & cons of RAID and ODS. We are running Sun Solaris 2.5.1 with VxVM and ODS 7.23 UC1. We planning for some expansive growth in our database(s). In our Sparc Storage Arrays (SSA), we are adding 4.1gb drives (largest drives supported for this model) to store our ODS database objects. In order to get the best possible performance, what have other Informix shops done. Some of the questions I have are: Q: Should I simply create two partitions per drive? This creates two 2gb partitions which the max chunk size for ODS. Q: Should I employ RAID 0+1? Get the benefits of striping and mirroring? Q: Is your decision different based upon OLTP vs DSS?
