<p class="MsoNormal">Personally, I wouldn't leave a system in that format, it's a waste of space. Cisco's docs seem to change because at one point, the docwiki specified that it could be built in either a raid 5 or raid 10 (for the app storage), but that has
been updated.<o:p></o:p></p>

<p class="MsoNormal">I'd personally setup a mirror with the first two for ESXI and then a raid 10 with the remainder drives. You get more IOPS out of it and should have plenty of space.<o:p></o:p></p>
