Ok, I see. The spare is visible only to RAID controller which automatically uses this drive if one of the RAID 1 mirror drives fails?

comment find out RAID level on HP DL360 server
Thanks! As I did not want to install additional packages to this appliance, I finally reloaded the server and looks like this is a dedicated spare drive. I guess RAID 1(1+0) in output of cat /sys/class/scsi_disk/0:0:0:1/device/raid_level means that?

Looks like that third HDD is a dedicated spare drive Does this mean that when one of the drives in RAID1 fails, then this spare drive will automatically take its place?

comment Number of CPU cores versus frequency of cores in hypervisor
I understand the RAS part now, but I'm still bit confused about the statement that more cores means that one is able to run more VMs. Why is that so? I mean for example in case of Core i7-4790K and Xeon E5-1428L v3 both are 16GHz in total if you sum the frequencies of the cores. Why should Xeon E5-1428L v3 support more VMs?

I see. So in general there is not a huge difference between same microarchitecture 4x 4GHz cores and 8x 2GHz cores if physical CPU is used for running virtual machines?

Does vCPU map to one core of physical CPU? And by reliability features you mean ECC memory support?
