From what I remember the warning level's default has always been at 90%.

That depends on the size of the disk group. Initially the recomendation was 90%, but 10% of a disk group with many big diks can be several TB, so for big disk groups you can raise it to 95%.

As long as you leave 2 x (biggest disk on disk group) free, it's fine.

When you create a Disk Group, the default setting is 90%.

I just did this last week on a re-initialized EVA5000 so I know it has not been changed since then.

The other guides you might be reading "might" be referring to a suggested setting based on the size of your disks and how many disks are in the group.

So, as usual in tests, you have to carefully analyze the question ;-)
Good luck!
