Fibrecat SX80 here with two disk enclosures and 16 SEAGATE 300GB SAS 15K ST3300655SS disks. The configuration is 1 RAID 5 array with 12 disks and 1 RAID1 array with two disks plus 1 global hot spare. One month ago 2 disks failed. We replaced them and then 1 week later 3 disks failed. Is there a possibility that the problem originates from the storage enclosures? Is there a way to check them, any diagnostic utilities etc
Thank you in advance.
