Looked through numerous answers around the varying RAID configurations and the best approach when dealing with ESXi. I still however have some outstanding questions.
There are 8x 300GB 10K SAS drives. This machine will house 5-7 VM's. As of now those would consist of 1 misc server, 2 db servers, 1 app server, 1 web server.
Based on research it would appear to simply go with 1 logical RAID 10 drive. This seems counterintuitive to the age old mantra of placing all your eggs in one basket and thus has me viewing it as a lackluster solution. I am unable to use a USB drive to host the OS (enterprise mandate); so the internal drives must be used. I really don't want too waste 2 drives on the OS either.
As of now my plan is:
7x drives in a single RAID 10 setup
1x drive as a spare
I'm looking to confirm my decision; in case something I am unaware of exists and would be a better route.
This will exist in a DL380G7 w/HP Smart Array P410i Controller FWIW.
