Yaniv,

You bring up a valid point.

I asked about RAID since I was concerned about drive failures & performance.
Since Gluster will handle data replication, using HBA seems like a better choice?

>From Yaniv:

I think there are two interesting questions here:
1. Why would you want RAID? Your data is replicated already on other
Gluster nodes. RAID writes will wear out the SSDs earlier and RAID 'wastes'
additional space. The reason may be because you don't want the node to go
down in case of a single disk malfunction. Fair - but is that the case?
2. I think HW RAID should be higher performing, but that's about it.
Y.

oVirt + Gluster (hyperconverged) RAID question:
I have 3 nodes of SuperMicro hardware, each node has 1x SATADOM
(boot drive for o/s install) and 6x 1TB SSD (to be used for
Gluster).
For the SSDs, is hardware or software RAID preferred or do I use an
HBA?
The RedHat docs seem to suggest hardware RAID, others on the forum
say HBA  or software RAID.

What are other folks using?

I'm using hardware raid.
