RE: AS/400 UPGRADE

["Richard Jackson" <richardjackson@xxxxxxxxxxxxxxxxxx>]

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.

We had the same system.  510/2143.  We also mirrored the two internals just
like you are.  You did not mention which IOP the other 10 drives are
attached to, Just the load source which are internal drives.  If you have
the 6512 it can handle 16 - 6607 drives with two raid sets of 8 drives each.
That is what we had on the 510 and brought to our 720.
Here is the WRKHDWRSC *STG listing from our 720.  It was the same on the
510.

Hi Richard,

Could you, if you know, how to find out if my IOP is incapable of supporting
more than 1 RAID set.  Are you also claiming that I have 48gig of DASD on my
510?  If so, could you explain the use of the mirrored DASD.  Below you'll
find detail information on my IOP.
