RE: AS/400 UPGRADE

[Chris Bipes <chris.bipes@xxxxxxxxxxxxxxx>]

What disk IOP would you recommend?  Or would you recommend added a second
IOP and splitting the drives?  So far, We have had excellent performance.
But then I do not know if we have ever monitored the IOPs performance.

Chris:

The 6512 IOP can be configured to support 16 arms in 2 RAID sets.
"Handling" 16 arms in a write-intensive environment is another question
altogether.

Beware: the PCI disk IOPs support a maximum of 15 disk arms.
