        Subject: Primary storage pool on disk
        
        

        Hi,
        
        I have a customer who wants to put his primary storage pool on disk.  
This is
        now 3TB and can grown up to 7TB.  Incremental backup is appr 
300GB/night.
        
        But I have some questions?
        - What kind of disks should I use?  (the customer has a FastT from IBM 
with
        fiber disks, but he wants a cheaper solution)
        - What kind of raid level as protection?  Raid5, JBOD, Raild 0+1, ... ??
        - Should I use a DISK type or FILE type storage pool?
        
        Thx.
        
        Stef
