To answer the original question, the two RAID5s is purely do to rebuild times in case of a failed disk. I suspect the factory pre-install for BE7K also came into play here since it's based off of that TRC. The flexflash was useful for ESXi but we aren't disk
space limited in TRCs so there isn't that much to be gained that I'm aware of.
<div><br>
</div>
<div>We specifically got rid of the RAID1 for ESXi because it wasted two disk spindles for the app that loads and runs entirely out of RAM. <br>
<div><br>
</div>
<div>I can't speak to the lack of RAID10 on TRCs. I suspect it's because we don't need it for iops and that anyone really passionate about it will be specs based anyway. </div>
<div><br>
</div>
<div>Do keep in mind that when you deviate from the official TRC you are technically specs based, with the additional support requirements that entails. That cost to the customer has to be considered, especially if they get into an ugly performance problem.</div>
