Best method for setting up RAID

#1

Post by philm »

Hello everyone,

This is my first time setting up a RAID installation. I am currently looking for the best method to setup a RAID for the NAS. The specs on my NAS are as follows:

AMD opteron 2346
16 gigs ECC RAM
The motherboard is this: http://www.supermicro.com/Aplus/motherb ... 8DME-2.cfm
Machine:http://www.ebay.com/itm/Supermicro-24-B ... 2196219084
24 HDDS: https://www.amazon.com/Hitachi-Deskstar ... B00VXO1WQ8

The HDDs are on a PCI SATA controller which the specs can be found here:http://www.supermicro.com/products/acce ... T2-MV8.cfm (I have 3 PCI SATA controllers with 8 SATA ports each)

The motherboard features an Nvida chipset that has hardware RAID capability. I believe that these is only for the 6 SATA ports on the motherboard. Would this be a correct assumption?

If so, then I would have to setup the RAID as a software RAID for the 24 HDDs which can be done in the NAS4Free software. There are two options for the RAID, a GEOM and RAID 0/1/5. Which one would be better or is this something that depends on the application?

Or would it be better to find a way for the Nvidia chip to register the 24 HDDs?

Yes, I was looking at using ZFS as the file system. Can NAS4Free do RAID-Z2 or at least RAID-Z?

Also, does anyone know what filesystem people tend to lean towards when running on a supermicro such as mine?

Also, what is the compatibility between filesystems using ZFS?

As in, am I able to move a file from a ZFS to FAT32 or NTFS system with no issue or is there some intermediate step I need to take?

cp ( or copy) is a useful program.
typically done on a system that has both filesystems mounted ( remote or locally). The mount will take care of
filesystem specific issues.
