DL380 Drive Setup (Mirrored or RAID 5)

[mgvogt11]

Can someone help me and tell me how I should setup my DL380 with 4 drives for CCM3.3 2. Should they be mirrored meaning 2 drives for the OS and 2 drives for the application? I just started this installation and researched everything except this. A quick response is needed. Thanks again.

Hi

There is not really 1 out there for CCM but have a look at the one for Unity. It gives some good practices on raid configs that can be applied to ccm as well.

In my opinion it should always be mirrored.

That way you can pop a couple of drives before upgrades and roll back very quickly if you get a dodgy patch.

I can't tell you the number of times I have been glad I can roll back quickly. I even have spare disks which I rotate every 4 weeks to ensure I always have a good copy to boot.

Thanks again. I setup the drives to be mirrored. I thought that was the practice but I wanted to make sure before I started. I appreciate the help.

Actually, you dont have a choice.

The OS install CD will re-configure the RAID into a mirror. If this is a 7835, and you have 4 drives you will likely have problems getting the right drives mirrored, because this is unsupported by the OS install.

The only model that supports 4 drives is the 7845.
