I am willing to assemble a oVirt "pod", made of 3 servers, each with 2 CPU =
sockets of 12 cores, 256GB RAM, 7 HDD 10K, 1 SSD. The idea is to use Gluste=
rFS to provide HA for the VMs. The 3 servers have a dual 40Gb NIC and a dua=
l 10Gb NIC. So my intention is to create a loop like a server triangle usin=
g the 40Gb NICs for virtualization files (VMs .qcow2) access and to move VM=
s around the pod (east /west traffic) while using the 10Gb interfaces for g=
iving services to the outside world (north/south traffic).
This said, my first question is: How should I deploy GlusterFS in such oVir=
t scenario? My questions are:
1 - Should I create 3 RAID (i.e.: RAID 5), one on each oVirt node, and then=
create a GlusterFS using them?
2 - Instead, should I create a JBOD array made of all server's disks?
3 - What is the best Gluster configuration to provide for HA while not cons=
uming too much disk space?
4 - Does a oVirt hypervisor pod like I am planning to build, and the virtua=
lization environment, benefits from tiering when using a SSD disk? And yes,=
will Gluster do it by default or I have to configure it to do so?
At the bottom line, what is the good practice for using GlusterFS in small =
pods for enterprises?
You opinion/feedback will be really appreciated!
