I want to use Glusterfs with Ovirt 3.5...please help me to make the architecture stable for the production use :- 

I have 4 servers...every server can host 24 SSD disk(As bricks)..i want to deploy distributed replicated storage with replica =2....i don't want to use the Hardware RAID...as i think it will badly impact the performance...

1. Glusterfs 3.5 or 3.6 ?? (which one will be stable for the production use).

2. Do i use the Hardware RAID or Not ??

3. IF HW RAID then which RAID level and does it impact the performance...

4. I want to make it rock solid...so it can use for production purpose...

5. How much RAM should be sufficient on each server...on the each server i have two E5 CPU's...

6. For Network Connectivity i have 2*10G NIC with bonding on each server...

Thanks,

Punit
