We are currently using a Fujitsu Eternus DX60 with NL-SAS disks as storage for our virtual machines.
During the last 18 month 8 out of 12 disks had to be replaced because the system claimed them to be failing. Fujitsu Support told me that this is totally normal.
Since our support contract will end within the next 6 month we need to decide whether to extend the contract or buy other hardware.
I'm not very experienced with storage systems, but i would expect less failing drives then what I learned from Fujitsu. Can anyone give me some rough numbers on how often drives need to be replaced in their storage systems?
Thanks in advance!
