if an EVA6400 storage is populated with 6 diskshelves and 36 disks with the type, are the RSSs made by 6 disks, in accordance to have each RSS made vertically across the 6 diskshelves ?
And to have the EVA6400 continuing after a diskshelve lost?
As a rule RSS's have 8 memebers. If you initialize an eva with 36 disks you get 3 8 member RSS's and one 10 member RSS. To optimize your stystem you should start with a multiple off 8 disks (40 in your case) If you realy think one RSS memember per shelf helps. You require 8 shelfs and a muliple of 8 disks. Then init your array.
RSS groups are made up of between 6 and 11 disks with the optimal being 8 disks. As far as I am aware the EVA will try to build as many 8 disk RSS groups it can then make smaller/larger groups for any that don't fit. So I would expect that in your case you would have 3 x 8 disk RSS groups and 2 x 6 disk groups. If you want to have the best chance of spreading RSS groups equally across enclosures you need to start with 8 enclosures and then add the disks in groups of 8 at a time.
