I have a dual controller netapp storage. Actually it is rebranded netapp bought from IBM - N6040. There are two disk enclosures connected to storage, one to the first controller and second enclosure to second controller. Disk enclosures are fible channel with 14 FC disk 15rpm. I created one aggregate for all disks in firts enclosure and one aggregate for all disks in second enclosures.
I am going to buy new enclosure with 14FC 15rpm disks. I was wondering how to configure it. To create new aggregate with disk for all disks in new enclosures or to add all disk to the current aggregate. Also how many enclosures is good to be added to the storage? I already read the specification, so maybe something from your experience.
I was told that it's better to buy new storage and not add more than couple disk enclosures. Is this true? Currently I have 10 blade servers connected to this storage through san switches.
