Re: Question on XIV and AS/400

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

Thank you all for your questions:

The LUN sizes are 34GB and there are about 30 of them. In the past I think we had 3 internal disks totaling 450 GB.

My XIV storage manager mentioned me he thinks the stripe size is a VIOS definition (not an XIV one) ... Is there an easy way I can check it? I do not know the machine (VIOS was configured by an external provider).
