Re: Question on XIV and AS/400

[Roberto José Etcheverry Romero <yggdrasil.raiker@xxxxxxxxx>]

And more importantly, how many disks and what of what kind composes
those LUNS? stripe size? there are lots of things involved in disk IO
performance...
DS4800 might be a high performance storage but you have to compare to
the original system, how many disks did it have? what kind of
controllers?

Best Regards,
