<br></div>1. 10.10.10.1 to 10.10.10.4 with 2 bricks each and i have distributed replicated architecture...<br></div>2. Now attached this gluster storge to ovrit-engine with the following mount point <a href="http://10.10.10.2/vol1" target="_blank">10.10.10.2/vol1</a><br>
</div>3. In my cluster i have 3 hypervisior hosts (10.10.10.5 to 10.10.10.7) SPM is on 10.10.10.5...<br></div>4. What happen if 10.10.10.2 will goes down.....can hypervisior host can still access the storage ??<br></div>5. What happen if SPM goes down ???<br>

Hi Juan,<br>
<br>
Understand...but if i am using replica=3 then ?? As using the HW raid<br>
with commodity HDD will be not good choice...and if i choose HW raid<br>
with enterprise grade HDD then cost will be higher and then there will<br>
be no use to choose glusterfs for storage...<br>

For replica 3, I don't think hardware RAID would be beneficial. HW raid is recommended for replica 2 scenarios with gluster to provide an additional degree of redundancy.<span class="HOEnZb"><font color="#888888"><br>
