We have a customer who is purchasing new hardware and has a question on RAID. They are planning on four RAID 1 drive pairs. Our Knowledgebase articles suggest that RAID 10 is preferred. Is this only with databases which exceed the capacity of a physical drive? Or would RAID 1 be sufficient? More detail from the customer below We intend to run Centos 7 (current latest version I believe is 7.3) Because this is an ERP (database) application, CPU speed is not super-important to overall performance, sufficiently fast disks and RAID card with caching we believe are more important to throughput. Because this R730xd can have up to 12 drives, and we’ve only added 8, we have room to add 4 more later should we need The 128GB RAM matches what we currently have and has been sufficient. Our thought is to setup as FOUR RAID 1 drive pairs, this allows us to control (at the OS/database level) what files are under which disk heads, to maximize performance, but on this question we especially would appreciate feedback, because this knowledgebase article http://knowledgebase.progress.com/articles/Article/21152 suggests RAID 10 is better, but I wonder if that is only with databases which exceed the capacity of a physical drive? We intend to upgrade from our current Progress 10.2A to 11.7 We would appreciate any feedback you have, especially as to how to setup the 8 disks for maximum performance
