Our production system will have two MSA70 arrays (plus two disk controllers) with each having 25 disks installed for data files. Other files are on other arrays. How should I separate this. I'm thinking each enclosure will have single RAID 10 array of 25 disks. Should I have multiple small arrays ? Should I have multiple data files ? Two on each array ? How can multiple data files help performance on single big raid 10 array ?
