Thanks experts. &nbsp;I'm weighing the increase through put using active/active versus pushing all storage capacity over to one controller to gain space.

Are your controllers loaded so much?

I have an old N3400 storage system with dual controllers.  I want to know if I can set up a global spare to maximize disk usage.  I currently have 9 2GB drives split 5 and 4 on each controller.  

Thanks.

Can I use a global spare on a IBM N3400 running OnTap 7?

IBM i, formerly known as AS/400, is a proprietary, midrange, object-based operating and application system. It includes a relational database, a menu-driven interface, support for multiple users, block-oriented terminal support and printers, and supports security, communications, and web-based application servers including Websphere, Apache and Tomcat.

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.
