<br>
I just implemented a (6x(4+2)) DISTRIBUTED DISPERSED gluster (v.3.10) volume based on the following hardware:<br>
<br>
- 3 gluster servers (each server with 2 CPU 10 cores, 64GB RAM, 12 hard disk SAS 12Gb/s, 10GbE storage network)<br>
<br>
Now, we need to add 3 new servers with the same hardware configuration respecting the current volume topology.<br>
If I'm right, we will obtain a DITRIBUTED DISPERSED gluster volume with 12 subvolumes, each volume will contain (4+2) bricks, that is a [12x(4+2)] volume.<br>
<br>
My question is: in the current volume configuration, only 2 bricks per subvolume or one host could be down without losing data. What it will happen in the next configuration? How many hosts could be down without losing data?<br>
<br>
Thank you very much.<br>
Mauro Tridici<br>
