Intel X99 Chipset RAID0

[htpcguru]

I'm setting up a box purely for gaming VM's.  I like UnRaid's VM management interface.  I've tried Proxmox which seems to be quite popular, but it is no where near UnRaid's flexibility and user-friendliness.

 

No HDD's for this box, only SSD's.  I can simply assign an SSD as a data drive, no parity, no cache, and UnRaid operates VM's happily.  Now I've just added another same-sized SSD, and set up an Intel X99 RAID0 volume with the 2 identical SSD's.  UnRaid, however, cannot see a single Intel RAID0 volume, instead, it still sees the 2 individual SSD's.

 

I've briefly searched the forum and came across this post.

 

Can someone confirm whether UnRaid works with motherboard or intel chipset H/W Raid?

AFAIK It doesn't.

I have now put a small HDD as an UnRaid data disk (as UnRaid won't proceed without a data drive), and assign the 2 SSD's as RAID0 cache.

 

root@Tower:/mnt# btrfs fi show /mnt/cache

Any tip on benchmarking the throughput of btrfs RAID0 implementation?

Yes, that's the best way to do it.
