Disk configuration

[zepelin16]

​

Hello everyone​

this is my first post, I've read enough for the forum, but just to be clear how to configure my disks, so I ask some advice about it.​

I have 5 1TB drives, and do not know which of the following would be the most appropriatesettings:​

5x1TB Raidz​

3x1TB Raidz , 2x1TB Mirror​

I'll use that to give is to network repository of all kinds of files (video, music, documents, ...) as well as drives for ESXi vmware (for ISCSI or NFS).​

​

regards​

(sorry for my English)​

What about 5x 1TB in a RAID-Z2?

I had considered, but with RaidZ lose less space

You should read this article: RAID5/RAID-Z1 is dead
A RAID-Z2 is considerably safer for your data. If you are doing regular backups though, you might be ok with a RAID-Z1. It really boils down on how important the data is and how much risk you are willing to take..

Also: A RAID-Z2 yields in the same available space as your proposed RAID-Z + Mirror combination.

I wanted to separate CIFS access to the ESXi ISCSI.
RAID-Z for CIFS, and Mirror for ISCSI ESXi

Sorry, I don't have any experience with ESXi, somebody else can chime in then.

Thanks, I will consider the RAID-Z2

A single mirror won't be great performance. I'd buy a sixth drive and stripe three mirrors in the pool for ESXi.
