Re: Question on XIV and AS/400

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

The important part is comparing the amount and capacity of disks from
the original system vs the amount and capacity of the assigned LUNs,
for example:

Original machine had 10x4326 = 10x36Gb (minus 1 for raid5)= 324Gb on 10 arms
New machine has 30x36Gb LUNs BUT it has only 3 disks = 1080Gb on 3 arms
You need to know how many arms serve those luns, to be able to
compare.Unfortunately i havent had a VIOS capacble machine so i cant
tell you how to query VIOS for some more info...

best Regards,

Roberto
