Even though our datasheet explains RAID 10 support, customer wants to know if we could demonstrate this in real system, we checked this by BIOS and also didn't find this kind of information.
Thanks, I have checked relative information to know we support MD RAID 10 over 2 drives, before customer suspect it is RAID 10 whcih requires 4 drivers.
I believe, the only option to demo it in real system is just to take one of the hard drives out from an appliance. This should prove that:
1. hard drives are in RAID
2. RAID functions correctly
PS if I'm not mistaken, it's not just RAID 10 which requires 4 drives, but MD RAID 10 (see difference here: Non-standard RAID levels - Wikipedia, the free encyclopedia )
NB! I wouldn't recommend to use this test approach as there is no 100% guarantee that hard drive which will be removed won't fail because of unexpected power and data cut.
