Sorry but that is the primary reason to not fully trust the client when it is 
your neck stuck out not theirs.  My guess is they did not want to spend for the 
enterprise drives got some hack in to “build” the server then when the guy 
figured out they were going to lose money supporting it they backed out.

well there was one more factor that influenced my decision (which I'm a bit 
embarrassed to say ??) dohh , after getting on call with dell, it turned out 
that these are NOT dell , or even enterprise drives.  I took the word of the 
client, and since I didn't see any yellow exclamations in the iDRAC it didn't 
dawn on me that these are consumer drives but that is what they told me the 
server is using  Samsung SSD 850

If you don't have seriously high iops needs, I doubt you need raid 10.  Jmho.

If I thought it was a site I couldn't get to quickly, I'd consider raid 6 with 
2 hot spares.  Call me crazy...

Decided on RAID 10 (6x500gb ) for a total of 1.5TB and the hot spare

Yeah, I’ve run into that as well (no hot spare) and I want to smack whoever did 
the design/config.


As for your question, “aside from a losing some space wouldn't a  raid 6 and 
hot spare make MUCH more sense?”


Well, the answer is, “it depends”  (probably, but I like throwing that out 




This site has been around for YEARS, and provides a good overview of the 
differences (pros/cons/uses) for different RAID configurations:






I used it about 7 or 8 years ago to help me decide whether to go with RAID 10 
or 0+1 on an Oracle DB configuration. (and no, I don’t remember which option I 
chose, or why).

“but still raid 5? and no hot spare?“  I’ve seen this more than once, There are 
a lot of people out there that were taught old school and that RAID 5 is the 
de-facto standard RAID setup so they stick with it for years and years!

So I inherited this server , (sitting on site since February) low and behold 
when I fire it up it turns out that whoever set it up used all 8 discs in a 
raid 5 (granted they are only 500gb enterprise ssd's ) but still raid 5? and no 
hot spare?


I'm trying to figure what the purpose of this server is/was, but aside from a 
losing some space wouldn't a  raid 6 and hot spare make MUCH more sense?


I'd like to move some of their VMs to it, as it is a brand spanking new r730 
with 96gb of ram
