You may be able to convert to raid 5, but raid 50 isn't an option on this unit (unless you were to run 2 raid 5's and then a software stripe across them (really bad idea)). I'd check your IO (read/write ratio, randomness, average/mean write size, etc). Then engage a performance consultant and get some feedback about whether the performance difference could impact you (significantly). You can change to a raid type with more space usually (e.g. from raid 10 to raid 5), but not the other way around.
Hi. WE have an MD3200 that has a disk group of RAID 10, but we need extra space and want to increase the size. Can we convert the Disk group from RAID 10 to RAID 50?   I can see on the Array manager you can convert the group to RAID 5, would this make us loose our data?   Thanks Johann
MD3200 Convert RAID 10 to RAID 5 or 50
