Hi,

Read best pratices paper (Attached).

EVa uses distributed sparing, the more space you leave, the more high available. For the disk group you can define spare drives!!

Hallo,
If you want resillience than create another diskgroup. You lost a lot of overhead.
If not the most important EVA rule, put as much disk as possible in a disk group, even if it different size or speed.
Best regards,
Herman
