Re: 70GB load source and 5 other drives

Sue, i meant presenting LUNs from a storage (say a DS5020). Those LUNs are
all from the same array so any IO to any of those disks really impacts the
array as a whole, in that case it should work the same as creating the
hosted disks on the host's ASP, right?

Sue, would that "the client load source would be busier, but
it should be spread on the host" statement apply to luns
presented thru VIOS? i believe it should, but i'd rather
ask... Always good to know best practices

If you follow the directions to get best VIOS hosted storage
using the wiki page

https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/IBM%20i%20Technology%20Updates/page/SAS%20Adapter%20Performance%20Boost%20with%20VIOS

the VSCSI drives are not spread across multiple units.
Therefore, it will matter if you have different sized
VSCSI devices.
