[Gluster-users] Gluster cluster questions

[Volker Dormeyer]

Hello All,

I am new to this list.

I am planning do create a cluster with several Gluster nodes. I get to
the following questions:

a) Is it possible to build a cluster with some of the bricks as SSD and
some of them with HDD? In the end I want two separate pools one fast
pool with SSD storage and a second slow pool with HDD. Is there a way to
define a scenario like this in Gluster? The question is not related to
SSD caching.

b) Or, shall I spilt this in two clusters of Gluster, one fast the
another one slow.

My imagination is to build something like this:


Kubernetes Cluster 1    ...    Kubernetes Cluster N
         |                              |
 storage class slow     <->     storage class fast

-----------------------------------------------------
                     \        /
                       Heketi
                     /        \
   Gluster 1 (fast)              Gluster 2 (slow)
